Product introdcution of ceramic fiber cotton
Ceramic fiber cotton is the high purity clay clinker, aluminum oxide powder, silica powder, chrome sand and other raw materials in the industrial furnace at high temperature melting, the formation of fluid. Then the compressed air is used to blow or the spinning machine is used to spin the silk into fiber, and the cotton is collected by the cotton collector to form ceramic fiber cotton. Fiber cotton can be further processed into fiber blanket, board, paper, cloth, rope and other products.
Features of ceramic fiber cotton
Ceramic fiber cotton is an efficient thermal insulation material, with light weight, high strength, oxidation resistance, low thermal conductivity, good softness, corrosion resistance, small heat capacity and sound insulation characteristics.
