Brief introduction of Ceramic wool insulation
Ceramic wool insulation is made of high-purity clay clinker, aluminum oxide powder, silica powder, chrome sand and other raw materials. Ceramic wool insulation can be further processed into fiber blanket, board, paper, cloth, rope and other products.
Features of Ceramic wool insulation
Ceramic wool insulation is a kind of high-efficiency thermal insulation material, which has the characteristics of light weight, high strength, oxidation resistance, low thermal conductivity, good flexibility, corrosion resistance, small heat capacity and sound insulation.
Applications of Ceramic wool insulation
- Thermal insulation of a thermal reactor
- Flexible insulation material for high temperature piping
- Thermal insulation material for incineration equipment
- Industrial kiln, boiler lining, back lining heat insulation fire insulation
