Knowledge of heat-resistant reflective coating

Answer 1

The heat-resistant reflective coating was a functional coating with the following characteristics, applications, and effects:

** 1. Characteristic **
1. ** Heat insulation and cooling method **
- Using paint coating to achieve the effect of heat insulation and cooling.
- It has a strong ability to absorb and spontaneously radiate thermal radiation electromagnetic waves. Through the absorption and spontaneous radiation of thermal radiation electromagnetic waves, it can block a large amount of radiant heat energy outside the heat transfer interface (coating) to achieve heat insulation.
- It can reflect the sun's heat (mainly the violet rays), and it can isolate and reflect the sun's heat. It can reflect at least 90% of it.
2. ** Durability related **
- Resistance to powder, aging, and corrosion of chemical media.
3. ** Color Effect **
- Color has a certain effect on thermal reflection, usually choosing white or light color can achieve better insulation effect.
4. ** Other characteristics **
- After curing, the specific gravity of the coating was only 0.46g/ml. It was a single-component modified water-based coating. It had the characteristics of high efficiency and thin layer, and it had the functions of heat insulation, decoration, waterproof, fireproofing, anti-corrosion, insulation, and so on.
- It has moisture resistance and can effectively prevent water vapor from condensing, keep it dry, isolate water vapor, and prevent moisture from corroding objects.
- Strong attachment, can be 100% attached, strong bond, can completely bond with the material, firmly attached to the surface of the object.
- It has anti-elasticity, which can prevent the expansion and contraction of the base material under different temperatures caused by cold/heat. It has good tensile strength and elasticity.
- Grade 10 mold resistance (Grade 1 - 10 of the standard, with Grade 10 being the highest)
- It was safe, flame-resistant, and not easy to burn.
- The paint itself or the waste produced during and after use will not cause pollution to the environment.
- It is economical, low cost, high performance/price ratio, high efficiency, and the comprehensive cost is lower than traditional materials.

** 2. Usage **
1. ** Industry **
- It can be used in metal oil tanks, chemical storage tanks, liquefied gas tanks, tank trucks, chemical pipes and other fields to reduce the surface temperature and internal temperature exposed to solar thermal radiation and improve the safety during transportation.
- It was used in construction, chemical engineering, oil, medicine, metals, aerospace, transportation, marine equipment, light textile, electronics, combat tools, and so on.
2. ** Construction Domain **
- It is suitable for concrete, wood products, and the outer layer of buildings to achieve the effect of heat insulation and cooling. The surface of the building was coated with a highly reflective heat-resistant coating, which could reduce the absorption of solar radiation heat by the building and reduce the transmission of heat into the room, thereby reducing the temperature rise and protecting the roof waterproof material. It can be used for heat insulation on roofs, exterior walls, and other building parts. For example, when used on walls under the sun, it can lower the indoor temperature by about three to four degrees lower than the outdoor air temperature. When used on roofs, it can withstand high temperatures, reduce temperatures, and block sunlight. When used in the open air, it can reduce the temperature of the radiated surface by more than 30%. The surface temperature of the painted object can be reduced by more than 20 ° C, and the space temperature of the object can be reduced by more than 5 ° C.

** 3. Construction related **
- For some heat-resistant reflective paint, it can be directly applied on the sand wall (unapproved lacquer), but pay attention to cover the mortar as much as possible. The construction is convenient and effective.

** 4. Effect **
- By measuring the surface temperature of the object with a temperature gun, it could be seen that the surface temperature of the object made of heat-resistant reflective coating was generally low. The effect was better when the surface was relatively flat after scraping the putty-powder, which was generally about ten degrees lower.
- It can prevent condensation water from forming when applied to objects with condensation water condensation environment. At the same time, it has the functions of heat preservation, waterproof, damp-proof, mildew-proof, scrubbing, and so on. When it is used for heat insulation, it can keep 90% of the heat of the object from being lost. When it is painted on the metal surface, it can prevent air and water contact while heat insulation, preventing metal corrosion to a certain extent and prolonging the service life of metal items. When it is painted on outdoor equipment, it can be used for heat insulation, water resistance, and sun protection, reducing the working temperature of the equipment.
