Now there is a kind of coating to improve the thermal infrared emissivity of the surface of the object, speed up the exchange of heat between objects, and improve the heat dissipation of heat energy. Moreover, the coating has good acid and alkali resistance, long-term corrosion resistance to acid and alkali, no discoloration or shedding, and long-term protection of the substrate. This kind of coating is the ZS-411 radiation cooling coating. We all know that there are three ways of heat exchange, convection, radiation and conduction. The heat transmitted by the object radiation has a decisive relationship with the temperature of the object. The higher the temperature of the object, the more heat the object radiates outward. This phenomenon is mainly due to the short wavelength of the object with high temperature and the high frequency of emission,

We all know that there are three ways of heat exchange, convection, radiation and conduction. The heat transmitted by the object radiation has a decisive relationship with the temperature of the object. The higher the temperature of the object, the more heat the object radiates outward. This phenomenon is mainly due to the short wavelength of the object with high temperature, the high frequency of emission, and the more heat it radiates. The surface temperature of the sun can reach 6000 ° K. It continuously transmits huge energy to the earth in the form of radiation wavelength between 0.15 and 4 microns. However, in the temperature range exposed to human beings, it is of practical significance that the wavelength is thermal radiation between 0.38 and 1000 μm, and most of it is located in the range of 0.76~20 μm in the infrared ray (also called heat ray) section. When the absolute temperature is 290K, then, infrared rays having a peak at a wavelength of 10 μm are emitted. Infrared heat dissipation coating is a new functional energy-saving coating developed and produced by Beijing Zhishengweihua Chemical Co., Ltd.

ZS-411 infrared heat dissipation coating is an energy-saving coating that radiates heat away from objects in an infrared manner and is anticorrosive and waterproof. The temperature resistance range is -50~600 ℃. The coating is directly applied to the surface of the object to be heat dissipation and cooling. The ZS-411 radiation heat dissipation and cooling coating can automatically radiate the heat away from the object to the atmospheric space at an infrared wavelength of 1-13.5μm, reducing the surface and internal temperature of the object, and cooling obviously. Heat dissipation coating fillers are materials with high thermal conductivity and infrared emission, such as carbon nanotubes and spinel metal oxides. These fillers can make the ZS-411 heat dissipation coating in Dongtieying, Fengtai District, present a macro-smooth and micro-wavy radiation structure unit after forming a film. Such a structure can greatly increase the heat dissipation area and conductivity, and significantly improve the effect of heat exchange. At the same time, the spinel metal oxide that has been transited by electrons can increase the electronic energy level, improve the infrared radiation coefficient of the object, and maintain the corresponding thermal stability, heat resistance, high strength, corrosion resistance, wear resistance and other excellent properties.

In addition, in order to improve the overall strength, aging resistance and thermal stability of the ZS-411 heat dissipation coating, the coating also includes nano-scale rare earth element oxides, which can improve the overall activity of the coating composition material and optimize the various parameters of the coating. ZS-411 infrared heat dissipation coating heat dissipation is not affected by the surrounding medium, coating heat dissipation can be used in a vacuum environment, the coating in the radiation cooling, but also has a good self-cleaning and anti-corrosion, energy-saving effect is remarkable.
