Alumina Ceramics:

The high temperature resistant and wear resistant ceramic coating is based on an inorganic binder and is combined with a light, hollow and loose ceramic microbead to form an inorganic coating film, which is blocked by an air microporous layer and a reflective layer having a low thermal conductivity. The heat energy transfer effectively suppresses the radiation heat transfer and convective heat transfer. In the high temperature environment, the sensitivity of the coating film to water is reduced. The silicon-oxygen bond of the high temperature resistant wear-resistant ceramic coating forms a network with higher hardness in the organic polymer. The structure, which increases the degree of organic film and temperature resistance, the two complement each other, forming a composite coating film with excellent performance, thereby achieving the purpose of lowering the heat balance temperature of the coated surface, and the heat insulation effect is remarkable. In the high temperature flue, the exhaust pipe is painted with high temperature resistant paint, the construction thickness is 3 mm, 800 degree burning and solidification, which achieves the function of thermal insulation and heat, and is beneficial to the emission of flue gas, reducing the generation of condensed water and avoiding unnecessary The pipe is corroded.

High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
