What are the functions of high temperature resistant coatings? What are the high temperature resista

High-temperature resistant coating is a kind of space energy-saving thermal insulation coating (space energy-saving thermal insulation coating includes high-temperature type and room temperature type), which is the world's first, the coating is an inorganic one-component, and the special solution is used without any peculiar smell. Temperature resistance range (-80-1800), high temperature insulation and thermal insulation coatings are only, can effectively inhibit and shield infrared radiant heat and heat conduction, heat insulation inhibition efficiency can reach about 90%, can inhibit the heat radiation and heat loss of high-temperature objects, can effectively keep cold for low-temperature objects and can inhibit the cold loss caused by ambient radiant heat, and can also prevent the occurrence of condensation of objects. High-temperature resistant coatings can also be used as high-temperature adhesives, which can withstand temperatures of 1800 or even higher, and can be used as coating materials such as ceramics, glass, and metals, as well as adhesives for ceramics, glass, metals, etc., and are widely used in metallurgy, petroleum industry, natural gas exploitation, aerospace and other industrial fields.

Smeared on the surface of metal and other objects at room temperature, drying at low temperature or self-drying at room temperature, the adhesion to the metal is very good, very hard, can not be scraped off with a blade, the strength is more obvious after high temperature calcination, and it is not cracking, it is resistant to 1800 degrees of high temperature, and can be used on the surface of metal iron, steel, aluminum, ceramics, glass, etc.

High-temperature resistant coating is an important coating, since the industrial production of silicone in the forties, the high-temperature resistant coating formulated with its products has been widely used in high-temperature motors, electrical insulation. For example, silicone aluminum powder paint is used in high-temperature anti-corrosion coatings for aircraft engines, and great achievements have been made, and silicone ceramic glass coatings meet the requirements of higher temperature anti-corrosion. But due to the poor mechanical properties of the silicone itself, adhesion.

Low abrasion resistance and solvent resistance are increasingly unable to meet the requirements of modern motors, electrical appliances, aerospace and special media, resulting in the emergence of a series of heterocyclic polymers. The polymer has been successfully used in special high-temperature engineering plastics, molding compounds, films, laminates, adhesives and coatings. In addition to the transformation of the pure silicon-oxygen backbone, in addition to the introduction of N, TI, P, B, etc. in the main chain, it is also modified with organic resin to make it heat-resistant, radiation-resistant, oil-resistant, hydrolyz-resistant, and wear-resistant.

Despite this, these new polymers have not yet been widely used in high-temperature coatings, and most of the products are still in the development stage.

High-temperature resistant coatings generally refer to special functional coatings that can withstand temperatures above 200 degrees Celsius for a long time and maintain certain physical and chemical properties, so that the protected objects can play a normal role in high-temperature environments. Borosilicate glass is used as the main filler to fill the resin matrix, which can form a new type of high-temperature resistant coating.

High-temperature resistant coatings can be divided into two categories: organic high-temperature resistant coatings and inorganic high-temperature resistant coatings. Lead phosphate powder coating is an inorganic high-temperature resistant coating. It has the characteristics of heat resistance, anti-slander and electrical conductivity, the raw materials are cheap and easy to obtain, and the preparation process is extremely simple.

This coating is commonly used to coat the plates of high-voltage electrostatic precipitators to extend the life and operation of electrostatic precipitators. Therefore, it has been widely valued by cement, metallurgy, electric power and other departments that use electrostatic precipitators.

1. If the coating is applied to the surface of the object at 1100 with 8mm, the surface temperature of the object can be reduced to less than 100.

2. Only 6mm thick high-temperature thermal insulation coating can reduce heat loss by more than 30% on the inner and outer surfaces of the furnace.

3. Brushing on the inner wall of the furnace and kiln will be smoother and smoother than the surface of any material and the flame infrared reflection function will reduce the heat absorption of the furnace wall and increase the flame temperature of the furnace.

4. Coat a box of minus 30 with a thickness of 10mm high temperature insulation and thermal insulation coating, and the temperature in the box is not higher than 0 for 24 hours.

5. The chloride ion content of the coating is zero, which can also prevent the chloride and sulfide in the air or wet in the process from entering the contact metal surface, which has a good anti-corrosion effect on the metal and will not lead to the embrittlement of the weld of metal welding.

6. The coating can be used in the flue, air duct, wind shield, etc., and the coating has good wear resistance and impact resistance.

7. The insulation coefficient of the coating is very high, and it has a good insulation effect at high temperature.

8. The paint does not have any peculiar smell, does not deform and does not decompose at high temperature.

High temperature electrical insulating coating.

High temperature electrical insulating coating is actually a ceramic coating, in addition to maintaining electrical insulation properties at high temperatures, it can also be closely "united" with metal wires, so that "seamless", even if the wire is bent around, it will not be separated, this coating is very dense, coating it, two wires with a large voltage difference touch together, and there will be no breakdown.

High-temperature electrical insulating coatings can be divided into many types depending on their chemical composition. Such as boron nitride on the surface of graphite conductors.

or alumina, fluorinated with copper coating, to 400 still has good electrical insulation properties. Enamel on metal wires.

to 700 , phosphate.

The inorganic binder coating based on the coating up to 1000 and the plasma spray alumina coating at 1300 still maintain good electrical insulation properties.

High-temperature electrical insulating coatings have been used in electric power, motors, electrical appliances, electronics, aviation, and atomic energy.

Space technology and other areas have been widely used.

1. High-temperature resistant coatings are widely used in auto parts, semiconductor technology, petrochemical industry, medical industry, electronic appliances and other fields. In industrial facilities, it is used for high-temperature corrosion protection of blast furnaces, flues, drying ducts, high-temperature hot gas pipes, heating furnaces and other non-side-excited metals and metal surfaces.

2. In the manufacturing industry, it can be used for automotive brake system parts, engine parts, semiconductor tools, high-temperature sensor probes, analytical instrument parts, microwave oven lead dates, heat-resistant parts and other parts that need to be exposed to high-temperature environments for a long time.

3. It can be used as a coating material for ceramics, glass, metal, etc., and can also be used as a binder for ceramics, glass, metal, etc., which is widely used in metallurgy, natural gas exploitation, aerospace and other industrial fields.

4. Inorganic high-temperature resistant coatings are commonly used to coat the plates of high-voltage electrostatic precipitators, which can prolong the service life of electrostatic precipitators and improve the operating conditions. Therefore, it has been widely valued by cement, metallurgy, electric power and other departments that use electric dust removal.

Thank you What are the main components of the durability of concrete?

It has certain impermeability, frost resistance, erosion resistance, heat resistance, etc., which is collectively referred to as the durability of concrete. Impermeability: refers to the ability of concrete to resist the penetration of liquids and gases; Frost resistance:

Refers to the ability of concrete to resist freezing; Erosion resistance: refers to the ability of concrete to resist erosion in various aggressive liquids and gases; Heat resistance: refers to the performance of concrete under the action of high temperature, the internal structure is not damaged, the strength is not significantly lost, and it has a certain chemical stability.

The durability of concrete mainly includes impermeability, frost resistance, carbonization resistance, alkali-aggregate reaction resistance, etc.

What is the heat resistance mechanism of high-temperature resistant materials? The heat-resistant mechanism of high-temperature resistant coatings is that in addition to resins, additives and other components, low-temperature molten materials are used in organic high-temperature resistant coatings, accounting for about 20%. Below 350 is used as a filler and mixed in the coating system.

This coating is suitable for use in environments with high operating temperatures.

1.High-temperature resistant coatings are usually made of silicone resin with good heat resistance as the base material, supplemented by Flamtard V, a low-melting glass powder of the Meiyang era**, as the backbone.

2.At 400 500 hours, the silicone resin decomposes in large quantities when heated, and the low melting point glass powder Flamtard V melts in this temperature range, instead of the silicone resin to act as a bond at high temperatures, thus forming a complete, dense coating with good adhesion.

The high temperature resistant paint is more common silicone high temperature resistant coating, the paint uses silicone resin as the film-forming substance, combined with high temperature resistant pigment fillers, solvents, additives, silicone high temperature resistant paint can be heat resistant, etc., with salt spray resistance, corrosion resistance, cold and heat cycle resistance and other advantages.
