Brief introduction of ceramic fiber cotton
Ceramic fiber cotton is a mixture of high-purity clay, alumina, silicate powder, chrome sand and other components, which is melted in an industrial electric furnace to form a liquid. Then, use the compressor blower or optical fiber press to combine the silk into fibrous tissue, and the fibrous tissue forms ceramic wool through the cotton gin. Fiber cotton can be processed into fiber clothing, board, paper, fabric, rope and other products.
Features of ceramic fiber cotton
Ceramic fiber cotton is an efficient thermal insulation material with light weight, high strength, antioxidant, low thermal conductivity, soft flexibility, corrosion resistance, small heat capacity and sound insulation.
Applications of ceramic fiber cotton
- Thermal reactor insulation
- Fire protection of various industrial equipment and thermal insulation of electrical appliances
- Thermal insulation materials for equipment combustion
- Components of modules, folds and application units
