Product introduction of ceramic fiber blanket
Ceramic fiber blanket adopts special aluminum silicate ceramic fiber filament, which is formed by special double-sided needle punching process. After the double-sided needle punching process, the interweaving degree, inner layer performance, tensile strength and surface flatness of the fiber are greatly improved. The fiber blanket does not contain organic binder, which ensures that the ceramic fiber blanket has excellent manufacturability and stability at high and low temperatures.
Advantages of ceramic fiber blanket
Ceramic fiber blanket has low thermal conductivity, low heat capacity, excellent chemical stability, excellent thermal stability and seismic resistance, excellent tensile strength, excellent sound absorption, etc. It is the best of thermal insulation refractory materials.
Applications of ceramic fiber blanket
- High temperature gasket
- Thermal insulation of high-temperature equipment
- High temperature pipeline thermal insulation
- Thermal insulation and fire protection of electrical accessories
- Fire protection and thermal insulation of military equipment
- Industrial furnace, heating device wall lining, back lining thermal insulation
