High temperature alumina ceramic rollers generally refer to the ability to withstand 1580 ° C at the temperature of the inorganic material. They built furnaces, combustion chambers and other building materials that required high temperatures. It is generally made of quartz sand, clay, magnesite, dolomite and other raw materials. The heat-resistant heat-insulating coating is a group of inorganic coatings with temperature resistance of 80-1800 °C and thermal conductivity of 0.03 watts/meter. It suppresses the heat radiation and heat conduction heat of high temperature and low temperature objects, and can maintain 70 high temperature objects.

The surface temperature of 1100 °C on the surface of high temperature alumina ceramic rollers can be reduced from 1100 °C to 100 °C. In addition to high temperature insulation, light weight, light structure, long life and other characteristics can also be used to make inorganic materials resistant to high temperature and acid. The use of alkaline adhesives, such as refractory cement, magnesium bricks, etc. In a broad sense, inorganic refractory materials, heat-resistant materials mean that these compounds have high hardness, good brittleness, chemical resistance and melting point above 1500, such as high temperature glass, also belong to refractory materials. High-temperature ceramic material technology generally has two series, organic series and inorganic series. As the carrier of silicone series high-temperature coating, the maximum temperature should not exceed 400 degrees Celsius.

High temperature ceramic materials above this temperature will occur in coke or softening, while inorganic range high temperature coatings can withstand temperatures of at least 1000 degrees Celsius, coatings can withstand temperatures of 1500 ° C or higher and thermal conductivity from Yunnan University Materials Department 0.06 watts / Cubic meters, a wide range of thin coatings can provide good corrosion resistance, thick coatings not only have good anti-corrosion effect, but also can maintain insulation effect.
