Brief introduction of Ceramic fiber cotton
Ceramic fiber loose cotton is used to melt high-purity clay clinker, aluminum oxide powder, silica powder, chrome quartz sand and other raw materials in an industrial electric furnace at high temperature to form a fluid. Then, the compressed air is used to blow or the spinning machine is used to spin the silk into fibers, and the cotton is collected by the cotton collector to form ceramic fiber cotton.
Applications of Ceramic fiber cotton
- Industrial kiln, boiler lining, back lining heat insulation fire insulation
- Thermal insulation of steam engine gas engine and other thermal equipment
- High temperature pipe flexible insulation material; High temperature gasket; High temperature filtration
- Thermal insulation of a thermal reactor
- All kinds of industrial equipment fire protection, electrical components insulation fire protection
- Thermal insulation material for incineration equipment
- Raw materials for modules, folding blocks and veneer blocks
- Investment castings are thermally insulated
