Product introduction of ceramic fiber cotton
Ceramic fiber is a kind of high-efficiency thermal insulation material. Ceramic fiber cotton is used to melt high-purity clay clinker, aluminum oxide powder, silica powder, chrome quartz sand and other raw materials in industrial electric furnace at high temperature to form fluid.
Features of ceramic fiber cotton
- Antioxidant
- Good softness
- Corrosion resistance
- Low thermal conductivity
Applications of ceramic fiber cotton
- Thermal insulation materials for incineration equipment
- Fire protection of various industrial equipment, thermal insulation and fire protection of electrical components
- Industrial furnace, boiler lining and back lining heat insulation, fire resistance and thermal insulation
