Liquid thermal insulation corundum. Technical characteristics and types of thermal insulation corundum Technical characteristics of liquid ceramic thermal insulation Corundum

20.06.2020

Preservation of heat indoors largely depends on the thermal insulation parameters of the building itself and the finishing materials. Reliably insulate the house - it means to reduce the cost of heating. Today, the construction industry offers many varieties of insulation materials that vary in their characteristics and cost. One of the best options is liquid thermal insulation Korund, which is durable and has excellent thermal insulation properties. Let us consider in more detail the features of the composition, selection criteria and application technique.

The unique composition of thermal insulation is also called heat-reflecting paint, since with a layer thickness of only 1 mm it can have a noticeable energy saving effect. Due to this, the thermal insulation of Corundum is very economical in terms of consumption. The composition of the filler includes microscopic hollow spheres - ceramic, polymer, composite, glass balls which are filled with rarefied air. Such microparticles can differ not only in composition, but also in the size of microgranules, percentage, uniformity of components, etc.

Externally, ceramic ultra-thin paint practically does not differ from ordinary acrylic-based paint. Despite the fact that today the construction market offers several varieties of ultra-thin insulating compositions, almost all of them have a similar structure:

Thermal paint is based on a water-acrylic solution. Its properties make it possible to ensure uniform distribution of heat-insulating components over the working surface. In addition, the composition contributes to better fixing of liquid ceramics.
The binder also contains different kind additives that improve operating parameters thermal paints. The most common material additives include natural and artificial rubbers, silicone, etc.

Liquid thermal insulation Corundum: technical characteristics and principle of operation

The temperature range for thermal paint varies from -65°C to +260°C. The main technical characteristics are vapor permeability and hygroscopicity of liquid insulation, which can be applied to almost any type of facade material: concrete, stone, brick, metal, plastic, etc.

This material guarantees the removal of condensate that forms on the walls and pipes in the room. The composition of such thermal paint includes special fixatives, catalytic agents, anti-corrosion additives, as well as a binder base on high-strength acrylic. Along with the content of microspheres, this composition is easy to apply and spread over the entire surface, providing good energy saving and thermal insulation performance.

An important argument to buy liquid thermal insulation Corundum is the safety of the substance. Due to the content of natural additives and environmentally friendly components, the treated surface is non-toxic and does not emit any odors. This allows you to use thermal paint to insulate any room. It is possible to create a resistant thermal barrier even in children's rooms or homes where allergy sufferers are located.

The thermal insulation properties of the composition can be achieved in several ways:

Through convection, i.e. heat transfer by the thermal paint layer itself. Due to the fact that most of the specific gravity of the liquid insulation consists of hollow balls, convection losses in the composition are quite insignificant.
The thermal conductivity of a material, when heat is transferred from a hotter part of the surface to a colder place. In liquid insulation, only 20% of the binder has thermal conductivity properties.
Radiation - a phenomenon in which heat transfer occurs through the internal energy of the suspension. In energy-saving paint, microscopic spheres are endowed with the properties of reflection and heat dissipation. Almost 90% of the reflected radiation turns the working surface of the wall into an analogue of a thermos.

Advantages of corundum thermal insulation

Liquid heat-saving paint is an innovative composition that differs from all existing coatings. Among the most significant advantages of its use, it is necessary to highlight the following aspects:

The versatility of matter. It can be applied to any kind of surface, including untreated, if indicated on the instructions for use. Specialists use thermal paint for processing brick, concrete, metal, plastic surfaces, as well as thermal insulation of equipment and air ducts.
Wear resistance. The applied layer of liquid insulation does not degrade over time. Corundum provides a guaranteed service life of up to 15 years, and with proper care (timely cleaning, high-quality finishing) can be doubled.
Ceramic thermal insulation has good adhesion to any type of material, which ensures good protection from moisture and air.
Substance is steady against the alkaline environment.
Liquid thermal insulation provides anti-corrosion protection and minimizes heat loss.
Dry coating with thermal paint reliably protects the treated surface from deformation due to temperature changes, atmospheric influences and moisture formation.
Ceramic thermal insulation is practical and easy to apply on surfaces of complex geometric shapes.
The material is ultra-light, which does not create an additional load on the structure. Due to this property, thermal paint is often used in roofing.
The substance is quite convenient to repair, because. in case of minor damage, the old layer can be easily removed, replacing it with a new one.
Thermal paint reflects up to 80% of the energy of ultraviolet rays.
In addition, liquid insulation is resistant to fire. When heated to + 260 ° C, the applied layer is charred, and when it reaches + 600 ° C, the thermal paint begins to decompose, releasing carbon and nitrogen oxide, which prevents the rapid spread of flame.

Disadvantages of ultra-fine thermal paint Korund

Despite the impressive list of advantages of the material, it is not without some drawbacks. Among them, the following aspects should be highlighted:

The high cost of thermal paint.
Since ceramic thermal insulation is a relatively new product on the construction market, there is no time-tested evidence that the material meets the stated characteristics.

The main types of thermal insulation

Liquid ultrathin thermal insulation is available for sale in specialized hardware stores in several versions. The entire line of polymer compositions consists of the following types:

Thermal insulation Korund Classic is a liquid suspension, which is intended for roofing and facade work. Also, this composition has found application in interior decoration rooms, providing reliable thermal insulation of walls in residential buildings and buildings general purpose. In addition, the classic variety is highly effective for insulating concrete floors, self-leveling coatings, hot and cold water supply communications, as well as window slope insulation.
Corundum Anticorrosive is a special composition for anti-corrosion purposes, which can be applied simply to a rust-covered surface, without special treatment. Such thermal paint is characterized by high adhesion to concrete and metal, creating a reliable protective and insulating layer. As a rule, this liquid thermal insulation Corundum is somewhat cheaper than the classical type and is used to create the first base layer of insulation.
Facade - a type of heat-saving paint intended for the treatment of concrete surfaces, as well as buildings made of cinder or foam blocks. The composition is applied in a thickened layer, thereby reducing the labor factor for processing surfaces of a large area. This type of thermal paint is usually used for finishing.
Winter is a liquid thermal insulation designed for work in the cold season. The principle of energy saving is based on the “thermal mirror effect”, i.e. reflection of the flow of heated air masses. This composition is universal and can be applied to almost any surface at ambient temperatures down to -10°C.

General criteria and features of choice

Ceramic thermal insulation is not yet a fairly common type of coating, due to the high cost of production. However, experts argue that this substance has exceptional performance characteristics, the value of which significantly exceeds the cost of acquisition. To choose the optimal type of liquid thermal insulation, it is important to consider the following features:

The first thing that affects the final result of processing with ceramic insulation is the density of the composition. High-quality thermal paint is characterized by an indicator of about 0.6 kg per 1 liter of product. Those. the weight of a standard bucket of 10 liters should not exceed 7.5 kg.
It is also worth looking at the container with the solution “in the light” to determine the degree of its separation. A good indicator of the quality and effectiveness of thermal insulation properties will be dense upper layer substances. As a rule, ceramic spheres have a light fraction that rises to the top. Thus, the thicker the upper layer, the higher the thermal insulation properties.
Not less than important criterion choice is the structure of the suspension itself. To determine it, you need to rub a couple of drops of heat paint between your fingers. AT qualitative composition microgranules of ceramic balls are felt, i.e. the substance is rough.
In addition, it is necessary to take into account the color of the liquid thermal insulation. Corundum is produced in white, so gray or yellow paint is a clear indication of counterfeit products.

Application area

Ultra-thin ceramic insulation Corundum is an innovative material that forms a durable elastic coating that reliably protects the surface from moisture, overheating and corrosion. This composition is used in the temperature range from -65°C to +260°C.

The main areas of application of thermal paint include:

housing and communal services facilities (including processing of pipelines for various purposes, thermal insulation of facades, roofs, windows, walls);
transport industry;
oil industry;
insulation of thermal power structures;
construction industry.

Ceramic insulation technology

It is necessary to apply ultra-thin thermal insulation Corundum on a previously prepared surface, regardless of the modification of the composition. The basic rules that should be followed before starting painting insulation include the following:

If ceramic insulation is intended for wall treatment, the work surface should be cleaned of dust and dirt, and existing gaps and chips should be expanded and filled with cement mortar.
Before carrying out painting thermal insulation on concrete slabs, they should be cleaned of "cement milk".
It is also necessary to treat the wall with an abrasive wheel, sandblasting machine or a hard metal brush.
If it is planned to treat a metal surface, it must be dedusted and degreased (substances recommended by the manufacturer - Solv-Ur, Solvent). For painting objects made of non-ferrous metal, it is necessary to remove the gloss and apply the primer composition VL-02 or VL-023.
It is also worth considering that it is necessary to dilute ceramic thermal paint immediately before applying it to the wall.

Important! It is recommended to mix liquid thermal paint Corundum manually. However, for work with large volumes, it is allowed to use a construction mixer, the speed of which should not exceed 200 rpm. Otherwise, there is a risk of destruction of the hollow ceramic granules, which will adversely affect the thermal insulation properties of the composition. As a rule, manual mixing takes 10-15 minutes. When working with a construction mixer, this figure will be 3-7 minutes.

It is also worth considering that it is necessary to add water to some modifications of the composition before starting work, so you need to carefully study the manufacturer's instructions. The volume of liquid depends on the purpose of the thermal insulation, in any case, the required proportions are indicated on the packaging of the composition.

The technique of applying ultra-thin thermal insulation Corundum is carried out in three ways:

with the help of air spraying devices;
airless spray method;
manually - using a roller or brush.

The manufacturer recommends applying the composition in three layers, while the consumption should be 1 m / m 2. When working on thermal insulation, this composition does not require additional ventilation in the room, as well as the use special means personal protection.

To guarantee the effectiveness of the result, it is important to strictly follow the manufacturer's instructions and fully adhere to the recommendations indicated on the package.

Conclusion

The use of ceramic thermal paint is an innovative approach that has undeniable advantages over traditional methods of thermal insulation of surfaces. The article discusses the main features of the liquid thermal insulation Corundum, reviews, selection criteria and the method of applying the composition. The resulting coating layer is characterized by lightness, excellent performance and ease of use.

FULLEREN SCIENTIFIC AND PRODUCTION ASSOCIATION LLC offers you a liquid ceramic heat-insulating material KORUND, which surpasses known analogues in its thermophysical properties. Own production, high-quality imported raw materials from the leaders of the chemical industry, allows us to offer our customers an exclusive line of modifications of ultra-thin heat insulators.

KORUND material has a full package of necessary certificates and fully complies with the declared technical parameters.

KORUND consists of a high quality acrylic binder, an original composition of catalysts and fixatives, ultra-thin-walled ceramic microspheres with rarefied air. In addition to the main composition, special additives are introduced into the material, which exclude the appearance of corrosion on the metal surface and the formation of fungus in conditions of high humidity on concrete surfaces. This combination makes the material light, flexible, stretchable, with excellent adhesion to the surfaces to be coated. Material similar in consistency to ordinary paint, is a suspension white color which can be applied to any surface. After drying, an elastic polymer coating is formed, which has unique thermal insulation properties compared to traditional insulators and provides anti-corrosion protection. The uniqueness of the insulating properties of Corundum is the result of the intense molecular action of rarefied air located in hollow spheres

Corundum material is highly effective in thermal insulation of building facades, roofs, interior walls, window slopes, concrete floors, hot and cold water pipelines, steam pipelines, air ducts for air conditioning systems, cooling systems, various tanks, tanks, trailers, refrigerators, etc. It is used to exclude condensate on cold water pipes and reduce heat loss in accordance with SNiP in heating systems. The material is operated at temperatures from - 60 C to + 260 C. The service life of the material, subject to the rules of application technology, is at least 15 years. To date, our material is used at facilities and enterprises different areas activities.

How does the material work from the point of view of thermophysics?

Let's start with the fact that there are three ways to transfer heat:

1. Thermal conductivity - the transfer of heat in a solid body due to the kinetic energy of molecules and atoms from a more heated to a less heated part of the body.

2. Convection - the transfer of heat in liquids, gases, granular media by flows of the substance itself.

3. Radiant heat transfer (thermal radiation) - electromagnetic radiation emitted by a substance and arising due to its internal energy.

Thermodynamics is a science that studies the laws of mutual transformation and energy transfer. The result of these processes is the temperature equilibrium in the entire system.

The method and effectiveness by which the insulating material blocks the redistribution of heat, i.e. the process of thermal equilibrium, and determines the quality of the insulation.

Heat transfer - convective or radiant heat exchange between the surface of a solid body and the environment. The intensity of this heat transfer is characterized by the heat transfer coefficient.

Liquid ceramic heat-insulating material KORUND is a complex, multi-level structure in which all three methods of heat transfer are reduced to a minimum.

The ceramic heat insulator consists of 80% microspheres, respectively, only 20% of the binder can conduct heat due to its thermal conductivity. Another part of the heat is due to convection and radiation, and since the microsphere contains rarefied air (the best insulator after vacuum), the heat loss is not large. Moreover, due to its structure, the material has a low heat transfer from the surface, which plays a decisive role in its thermal physics.

Thus, it is necessary to separate two terms: Heat Insulator and Heat Insulator, because in these materials the physics of the heat transfer process is different:

▪ insulation- the principle of operation is based on the thermal conductivity of the material (min. plate)

▪ heat insulator- to a greater extent on the physics of waves.

The effectiveness of the insulation directly depends on the thickness: the thicker the insulation layer, the better.

The thickness of the heat-insulating layer of the ultra-thin KORUND heat insulator varies from 1 to 6 mm, the subsequent increase has practically no effect on its effectiveness.

Today, Korund has the following industrial modifications -

1. Corundum Classic.

The basic modification is the best liquid thermal insulation. It is a film-forming modification that allows you to isolate objects with a surface temperature of up to +200 ° C on a permanent basis.

2. Corund Facade.

For the first time in the world, a material has been developed that can be applied in layers up to 1 mm thick at a time, and has increased vapor permeability.

3. Corundum Anticorrosive.

For the first time in Russia, a unique material has been developed that can be applied directly to a rusty surface. It is enough to simply remove the “raw” (loose) rust with a metal brush, after which you can apply KORUND Anticorrosive thermal insulation, following the instructions.

Thermal insulation Korund Anticorrosive is a highly effective thermal insulation coating with additional anticorrosive properties, and not only a preservative and corrosion modifier. All technical characteristics, requirements, instructions for use are the same as for the main material KORUND. The use of KORUND Antikor for thermal insulation of existing structures and pipelines significantly reduces labor costs, since it does not require special preparation of the working surface. Thermal insulation Corund Anticorrosive should be applied as the first layer, and for subsequent layers (for the sake of economy) you can use the "classic" thermal insulation KORUND.

4. Corundum Winter.

For the first time in Russia, a material has been developed that can be worked with negative temperature. Corundum Zima is the latest development in the line of ultra-thin liquid ceramic heat-insulating materials. Unlike all other GI materials presented on Russian market, work on applying Korund Winter can be carried out in winter period, while the minimum temperature for applying ordinary LCTMs cannot be lower than +5 °C Corundum Zima consists of a composition of special acrylic polymers and foam glass microgranules dispersed in it, as well as pigmenting, flame retardant, rheological and inhibitory additives.

Now the "winter recession" in construction is not terrible for you!

Corundum - thermal paint developed by Russian specialists and a new word in thermal insulation of any surfaces. Some types of this paint work even at temperatures above 500 degrees. And all because the material is not combustible.
Easy to apply, Corundum is a thermal insulation that lasts for a long time, from 15 years, and in terms of heat preservation replaces an additional wall of one and a half bricks.
Thermal paint is a unique development that gives protective properties to the walls of buildings, facades, concrete slabs. Using corundum paint, you save money on thermal insulation.

According to its composition, it is a suspension, water-based or varnish-based, which covers various surfaces well, even with irregularities. The consistency of the paint is pasty, the color is gray or white. It is convenient to work with a brush, roller or sprayer. The greater the thickness of the thermal paint, the higher the thermal protection will be. Its service life is from 15 to 40 years.

Insulation paint - multifunctional. It keeps heat well, does not allow water to penetrate into structures, and protects against mold formation. Corundum thermal insulation extends the service life of pipes, tanks, refrigeration equipment, air conditioners. Keeping warm is the main purpose of thermal paint, so it is indispensable for thermal insulation of pipes. The materials currently used are short-lived and harmful to humans. Pipes covered with corundum thermal insulation endure exposure to precipitation and sunlight.

According to sad statistics, a huge number of fires occur through the fault or with the direct participation of heat-insulating materials. Often the walls are lined with combustible thermal insulation, and in case of fire, fire with lightning speed with the help of this insulation spreads throughout the building, spreads to the roof and neighboring entrances. To prevent this from happening, use heat paint. It is an inexpensive, safe in all respects material that does not support combustion.

Liquid thermal insulation Korund passed climatic tests, which showed that the effectiveness of protection of coated products is maintained for at least 10 years.

Thus, ultrathin thermal insulation Corundum is an effective technological material that meets all the requirements that apply to this class of thermal insulators. Among its shortcomings, it can be noted that in the presence of performance characteristics inherent in all ultra-thin insulations, it differs in an unfavorable way by a higher price.

An innovative material that appeared relatively recently, but has already managed to attract a lot of attention in relation to itself. Why? The liquid base of ceramic thermal insulation Corundum changes the idea of insulating materials after the first use. The substance forms a sufficiently thin film, which has protection against aggressive environment and minimum thermal conductivity. An interesting point is the weight of the thermal insulation material before and after application. When the composition dries, its weight decreases to an insignificant figure and is almost invisible.

The use of such material as liquid ceramic thermal insulation Corundum has very specific goals:

Protection from external factors and maintaining integrity;
Insulation of pipeline systems;
Thermal insulation of the room.

Korund has made sure that its products are as effective as possible for its customers by presenting the following products to the market:

Classic

It has multifunctional properties and is resistant to temperature runoff (-60/+200 °C) and is able to withstand short-term critical temperature points (up to 260 °C). Designed specifically for the insulation of the main elements of the building: plumbing, heating boiler, walls, openings, facade decoration and other partitions that protect the room from climatic conditions.

Facade

This thermal insulation from Korund was created to insulate the facade of the room (residential or not, it does not matter). It has good adhesion to many surfaces, that is, high-quality use is available with almost any facing material. It has a high rate of resistance to weather vagaries and retains a greater amount of heat generated in the room, compared to foam insulation.

Anticorrosive

A unique coating to protect and prevent the effects of rust. Possesses high rate in terms of corrosion resistance. The mixture has been widely used for thermal insulation and protection of reinforced concrete and metal structures, pipes, which are used everywhere, as well as other metal products used in construction. It boasts such an opportunity as applying the mixture to the surface without first removing traces of plaque and rust.

Winter

Insulating coating, which is designed for conditions with low temperature properties. Thanks to special composition, has resistance to adhesion from surfaces after application. Including those surfaces that have a different basis - liquid and solid. In addition, such a coating protects well from the effects of alkali, salts and many acids.

The use of liquid material - ceramic thermal insulation Korund

The use of such a heat insulator does not require special expensive tools. A standard air gun will work well. It is also possible to work with such improvised tools as a roller and a brush. The application itself is simple and fast. The coating that forms the heat insulator from Corundum is smooth and seamless. This property has a good effect on the preservation of heat.

Liquid thermal insulation Corundum is a kind of coloring material, after application of which, a high-quality ceramic thermal insulation layer is formed on the surface, which also protects the surface from the negative effects of corrosion.

What is liquid thermal insulation Korund

Do you need to carry out internal thermal insulation of the walls of the room, while you want to lose a minimum of free space? Or do you need to isolate the walls from the outside, but at the same time you want them not to lose their attractiveness? appearance and that a minimum of Money? Then one right decision will use liquid thermal insulation Corundum.

Residents of our country have been living in houses with non-insulated walls for many years. And all this because they are afraid of a long, laborious and expensive process of warming. But today there is a material that can effectively, quickly and inexpensively solve this problem. And this material is liquid corundum thermal insulation. If you go through hardware stores, you can find a lot of ceramic-based heat-insulating materials. But relatively recently, scientists have developed such a heat-insulating material that is better in its technical and operational characteristics than analog materials, while its cost is no different.

Scope of liquid thermal insulation Korund

Due to the fact that Corundum thermal insulation has a liquid consistency, it has a lot of advantages over its direct counterparts, since it can be applied to a wide variety of surfaces:

Roof;
window slopes;
Pipes;
Facades of buildings;
Various kinds of containers;
Internal and external walls;
Cooling chambers.

In order to prevent the formation of any condensate on the surface of the pipeline, and hot water came to you with meager heat losses, it is recommended to treat the pipes with liquid thermal insulation Corundum. Duration operational period such a coating is equivalent to 15 years, such thermal insulation can withstand significant temperature fluctuations from -50 to +250 degrees, no analogue can boast of such technical and operational characteristics, and this is subject to the relatively low cost of the material.

Advantages of liquid thermal insulation Korund

The main advantages of liquid thermal insulation Corundum include the following positive points:

The application process can be carried out independently, for this a regular brush or sprayer can be used;
Just one millimeter of liquid thermal insulation Corundum will provide the same properties as 600 mm of rolled thermal insulation material;
Considered waterproof, not exposed to negative influence saline and ultraviolet radiation;
Provides visual access to the inspection of the isolated surface;
It is a fire-fighting material that does not support the combustion process. When exposed to 260 degrees, the material is charred, but if the temperature rises to 800 degrees, then the process of decomposition begins with the release of nitrogen oxide and carbon, and these substances stop the combustion process.

Thermal insulation corundum

The ultra-thin liquid ceramic thermal insulation Korund offered on the market is the optimal solution for many cases in terms of its product protection efficiency, durability, ease of application, but unfortunately not the price. Superfine thermal insulation Corundum is liquid composition water-based, the main component of which is a polymer latex composition. Its scope is from covering the walls of buildings and structures to thermal insulation of various types of pipelines (air, water pipes). It is also used for application to various types of industrial equipment.

Properties of liquid ceramic thermal insulation Corundum.

Like all ultra-thin thermal insulations, in addition to direct thermal protection, Corundum also prevents corrosion. In addition, the material has dielectric properties. However, in terms of price-quality ratio, it is somewhat inferior to analogues - for example, Aktorm liquid thermal insulation.

Corundum, like all representatives of this class of materials, has a significant advantage over traditional insulation using mineral wool, as it lays down in a continuous layer, leaving no gaps. In the case of mineral wool, unprotected areas always remain, which are channels for the flow of heat. In addition, Corundum is very simply and quickly applied to almost any kind of surface. In this case, it does not really matter whether it is a plane, a rough wall, or complex-shaped equipment. The composition lays down in an ultra-thin layer, providing maximum thermal insulation, the application process itself is almost the same as conventional painting and does not require much time. The composition can be applied at temperatures up to -10 ° C, which is approximately equal to or even slightly inferior to that of Aktorm thermal insulation.

Consumers who have used Corundum clearly distinguish this thermal paint from similar ones. Even if you don't have special equipment, just putting your hand to the wall covered with Corundum, you will feel warm, while the unpainted wall will cool your hand.

Corundum - the warmth of your home!

During the construction of houses, special attention is paid to thermal insulation. In the conditions of the cold winters of our country, such additional protection will be very useful. Insulation will significantly save on heating and increase the comfort of living in the house. There are many thermal insulation materials on the modern construction market. Everyone has their pros and cons, and sometimes it is very difficult to make a choice. In order not to be mistaken, it is better to learn more about the characteristics of each. In this article we will talk about such material as liquid thermal insulation Corundum. Its characteristics will be given and its advantages and disadvantages will be discussed.

Material Features

Corundum thermal insulation has recently become very popular. This is modern method using special ceramic thermal paint. Outwardly, such material is not much different from ordinary paint. All the most important is hidden inside.

Liquid thermal insulation Korund is made from a mixture of water-acrylic mortar and ceramic fillers. The first component allows the material to evenly distribute heat-insulating elements over the entire surface. And hollow ceramic spheres of microscopic dimensions act as a heat-insulating element.

Due to its composition, thermal insulation with Corundum is carried out quickly and evenly covers the entire area, going even into the most hidden areas.

Characteristics

can be carried out on any surface. Thermal paint adheres perfectly to concrete, brick or masonry, plastic or metal structures.

This material easily withstands a wide temperature range. Liquid thermal insulation "Korund" does not lose its characteristics both in extreme cold (up to -65 degrees) and in strong heat (it easily withstands temperatures up to +260 degrees).

Possessing low thermal conductivity, even a thin layer of material perfectly retains heat. Thermal insulation Corundum only 2 mm thick works more efficiently than a layer of mineral wool 60 mm thick.

Main specifications liquid heat-insulating material Corundum are as follows:

elasticity in bending - 1 mm
adhesion to concrete - 1.28 MPa;
adhesion to brickwork– 2.0 MPa;
adhesion to steel surfaces - 1.2 MPa;
thermal conductivity - 0.0012 W / m ° C;
heat transfer - 4.0 W / m ° C;
vapor permeability 0.03 mg/mh Pa

All these characteristics make Corundum the best heat-insulating material.

Advantages and disadvantages

Liquid thermal insulation Corundum is modern high-tech material. E If we talk about its advantages, then it is worth noting the following:

But this material also has its drawbacks. Yes, they include high cost heat insulator Korund. In addition, the material is new, so all of its declared characteristics have not yet received their practical confirmation.

Varieties of material

Liquid thermal insulation material Corundum available in several versions. The manufacturer offers to purchase the following varieties:

Classic - this product is widely used in roofing and facade works. Also, this brand is perfect for thermal insulation of interiors with any type of coating. Classic is a universal and highly effective heat-insulating agent;
Anticorrosive. This material is primarily used for anti-corrosion coating of metal structures. At the same time, a protective layer can be applied directly to areas with rust, without any pre-treatment;
Facade - this kind of heat-insulating material is specially designed to cover concrete, cinder-concrete and foam concrete walls and designs. It is applied in a thickened layer, which speeds up work and improves thermal insulation qualities. This variety is most often used for finishing the facades of houses;
Winter. Not always all thermal insulation work is completed in the warm season. If the insulation is carried out at temperatures up to -10 degrees, then this particular type of thermal paint should be used.

There are a number of other types of this liquid thermal insulation material, but they are used less frequently. But no matter what brand of Corundum you use, high thermal insulation properties of the coating are provided.

How to apply?

Whatever kind of liquid thermal insulation Corundum you use, before applying it, you must properly prepare the ground. First of all, the entire surface is cleaned of debris and contaminants. Weak areas, “cement milk”, and old molar coating are removed. If there are gaps and cracks, then they are sealed with a sand-cement mortar. Then any surface must be treated with an abrasive wheel or a simple metal brush.

The paint itself for thermal insulation must be mixed according to the attached instructions from the manufacturer. The most important thing is to mix manually. If use mechanical way, the ceramic microspheres may be damaged and the thermal insulation effect may be impaired.

The heat paint itself is applied by hand or with paint sprayers. You are just painting the surface. When working, there is no need for protective devices for breathing or forced air flow. Corundum is absolutely safe for humans.

Conclusion

Corundum thermal insulation is a modern, high-tech tool. With it, you can effectively insulate houses and any other structures. Therefore, despite the rather high price, Corundum is very popular, both among construction companies and among private homeowners. And the ease of its use allows anyone, even an inexperienced user, to cope with the insulation.

Liquid ultrathin insulation (as an analogue) is a new word in the matter of thermal insulation of structures. Standard methods of thermal insulation are still good, but little by little more effective solutions are coming to replace them.

Liquid insulation is just such a solution. It is able to protect the structure from freezing, while being essentially more of a paint and varnish material than a heater in the form in which we usually imagine it.

In this article, we will present to you all the nuances and features of Corundum liquid thermal insulation for consideration.

1 Features of liquid insulation

Liquid thermal insulation Korund is produced by the association of companies Fulleren. They have been manufacturing this material for many years and have managed to achieve quite serious results.

Note that liquid-type thermal insulation has not been invented recently. It is intended for the same insulation work, but it is only reproduced in a unique form.

Standard insulation is special material with low thermal conductivity. It cannot transfer heat and perfectly delimits zones with different temperatures by being in it a large number air.

That is, the insulation has a certain thickness, it is laid on the surface of the walls, thereby protecting them from the effects of external temperatures. As you yourself know, the working thickness of the plate can reach up to 10 cm or even exceed this figure.

But the characteristics of the heat-insulating material Corundum are completely different. This insulation is not in vain called liquid. If you look at it uninformed, then the composition can be confused with ordinary paint.

Indeed, this type of thermal insulation resembles paint in consistency, is applied like paint, and even the coating forms a similar one. However, after application, an ultra-thin heat-insulating film with unique parameters is formed.

This is possible due to the unique structure of the Corundum material (like y).

1.1 Insulation composition

In addition to the standard name in the form of liquid thermal insulation, this insulation has a different name - ceramic.

It is called ceramic not because it consists of ceramics or forms a ceramic surface. On the contrary, the main filler in Corundum insulation is an acrylic-type polymer, only more dense.

Ceramic insulation incorporates ceramic hemispheres with insulated filling. These hemispheres and allow you to create insulation with a thickness of 1-2 mm.

However, an ultrathin film does not consist of only hemispheres. It also contains anti-corrosion type additives, polymers, etc.

Together, they form a heater for walls, floors, ceilings, pipes, and in general any structures available to you.

After solidification, the polymer seizes, forming a very strong film, inside it there are frozen spheres, which occupy more than half of the space. They repel any thermal energy, protecting the insulated structure no worse than a mineral wool layer that is quite impressive in size.

1.2 How it works

Instructions for use states that Corundum insulation with a thickness of only 1 mm can replace up to 5 cm of mineral wool insulation. That's really super-thin thermal insulation. But how does she do it?

And everything is very simple. The fact is that when creating the Korund insulation, the developers were initially guided by the desire to eliminate heat loss in all three main areas. And these directions are probably familiar to you.

Heat loss in building structures most often occurs due to:

Heat transfers;
convection;
Radiation (even if it costs).

Heat transfer is quenched by most standard heaters. But at what cost? To level the temperature difference, a person has to use a bulky insulation with a thickness of 5 cm or more.

At the same time, it must be laid on glue or in a special frame, and then veneered. Liquid thermal insulation performs the same functions, only its structure is ten times denser, and the thermal conductivity index is almost zero.

That is, when finishing the walls, the applied liquid in the same way will not allow the air to exchange temperature with their insides, but at the same time, an ultra-thin film acts as protection here.

Convection is the transfer of heat from object to object. A highly controversial method, because in conventional construction he plays almost no role.

However, the liquid ceramic heat-insulating material Corundum can completely remove this moment.

But with radiation, things are much better. Thermal radiation standard insulation materials are not capable of extinguishing (for example, inefficient).

That is, they can only take over the radiation, but a certain amount of it will still reach the surface of the walls. Meanwhile, radiation comes from all warm objects, especially from heaters.

For additional protection, it was necessary to combine ordinary insulation with foil. The foil reflected the waves, and the insulation went about its usual tasks.

But the liquid thermal insulation Corundum repels radiation by almost 90%. Residues are simply extinguished and dispersed close to the surface of the walls.

The result is a situation where all three main expenditure items are removed by just one ultra-thin protective film. Surprisingly, customer reviews are also completely in solidarity. Corundum insulation really works and does its job well.

1.3 Pros and cons

When choosing thermal insulation, it is important to pay attention to all parameters. Take into account technical characteristics, reviews and even consumption. However, first of all, you need to look at the properties of the insulation. What makes him good, and what, on the contrary, repels you.

Developers do not eat their bread in vain. Corundum insulation has a huge list of advantages and a minimum of disadvantages. So let's deal with them in more detail.

Main advantages:

Can be applied to walls, floors, load-bearing structures, roofs, pipes, etc.
The work is done by hand, improvised means are also suitable.
Dries quickly.
A thin protective layer replaces up to 5 cm of standard insulation.
Not exposed to external influences.
Not afraid of moisture.
Does not respond to temperature changes.
Non-combustible.
An elementary method of application, as in the case of.

And this is not the whole list. Full characteristics can be assessed only after you have the instructions and certificates for Corundum thermal insulation in your hands. But even from it it follows that the material is extremely useful.

What is only worth the fact that it can be applied with a regular brush. That is, any structure that can be reached can be processed.

And now remember the standard processes of insulation. How much time should be spent to finish one column with mineral wool. And what can we say about the surface of the walls, which are surrounded by a large number of pipes?

While Corundum insulation will not cause you such problems. All you need to do is stir it up and put it on the wall. Not surprisingly, the reviews about her are all completely positive.

Main disadvantages:

Pretty high price.
Serious expense.

As for the shortcomings, they are quite trivial. Like any innovative material, Corundum insulation is expensive. This is the cost of production.

The second point, which partially overlaps with the first, is the serious consumption of paint. Corundum should be applied in several layers. Accordingly, the consumption of such material will be very serious.

It is desirable to apply at least 4-5 layers on the surface of the outer walls. This is the only way to form a high quality insulation, and be sure that it will not crack or peel off.

2 Types and differences

Corundum insulation comes in several varieties. Each of them has its own technical nuances.

There is a corundum insulation:

Classic;
Facade, Facade-Lotus;
Anticorrosive;
Winter;
Fire protection.

Liquid thermal insulation Korund Classic is a standard option that is used almost everywhere. Thermal paint is easy to apply, dries quickly and has good strength parameters.

Thermal insulation Korund Facade is intended for exterior finish walls. The Facade-Lotus sample is the front, the second level of insulation. Applied for extra protection.

Model Antikor - insulation with enhanced anti-corrosion properties, ideal for protecting wood.

The Winter model differs only in the possibility of application at sub-zero temperatures.

Well last option- paint that swells upon contact with fire, protecting the structure from fire.
