High temperature resistant far infrared radiation coating is a special function of high temperature resistance, strong radiation rate, corrosion resistance and high wear resistance Energy-saving coating is developed by Beijing Zhisheng Weihua Chemical Co., Ltd. after many years. The coating is processed using nano-dispersion synthesis technology to form a dense ceramic radiation coating on the lining of high-temperature kilns and furnaces. The coating optimizes the kilns and furnaces. Thermal energy utilization.
Industrial kilns, furnaces, and boilers usually burn at high temperatures above ℃. The furnace structural materials are mainly various refractory materials such as high bricks, quartz sand, clay bricks, castables, ceramic fibers, etc. They It is not only the structural material of the furnace body, but also a heat insulation, wear-resistant and anti-erosion material. It also participates in the radiant heat exchange process. Their thermal radiation performance and insulation performance determine the thermal efficiency of the kiln, making it difficult for a single material to achieve firmness. Comprehensive requirements of structural, high thermal insulation and high radiation properties.
Generally speaking, when the temperature in the kiln and furnace is above ℃, the heat transfer is mainly radiation. Radiation heat transfer is times of convective heat transfer, accounting for more than the total heat exchange. Most of the wavelengths of high-temperature radiation energy are concentrated in the ~ band, such as ℃ and ℃, respectively, and the radiation energy is concentrated in this band. The emissivity of general refractory materials in this band is very low, while the high-temperature far-infrared radiation The coating has a high emissivity in the ~ spectrum range. >

The emissivity of refractory materials at room temperature is generally .~. As the furnace temperature increases, it will drop significantly. At high temperatures, it is only .~., while high-temperature resistant far-infrared radiation coatings can The infrared emissivity above has been maintained. >

According to Kirchhoff's law, the absorptivity and emissivity of a material are equal. When the emissivity of an object's surface increases, its ability to absorb heat also increases accordingly. Since under high temperature conditions, heat transfer is dominated by radiation, when the surface of the heated object is coated with a nano-micron high radiation coating, the ability of the heated object to absorb and emit heat is greatly improved. Under the same heating conditions, due to The improvement of heat transfer capacity will greatly improve the utilization efficiency of thermal energy, thereby achieving the purpose of energy saving.
Based on the actual working conditions of the above furnace body, Beijing Zhisheng Weihua Chemical Co., Ltd. has used high-temperature resistant far-infrared radiation coating to improve the heat exchange in the furnace through infrared radiation through thousands of tests and the use of specific furnace bodies. Working conditions, improve the combustion temperature and uniformity in the furnace, make the fuel burn more fully, increase the thermal efficiency, greatly improve the thermal efficiency of refractory materials, reduce energy consumption, save energy and extend the service life of the furnace lining.
In addition, high-temperature resistant far-infrared radiation coating on high-temperature metal pipes can speed up the heat transfer from the environment around the metal pipe to the pipe, speeding up heat energy exchange.
