Product description of ceramic fiber board
Ceramic fiberboard is aluminum silicate fiberboard, a refractory material made of board. The product maintains good mechanical strength even after heating. Compared with the fiber blanket and felt, the product is a fiber heat insulation product with rigidity and support strength.
Advantages of ceramic fiber board
Ceramic fiber board in addition to the corresponding loose ceramic fiber cotton excellent performance, the product is hard, toughness and strength, with excellent wind erosion resistance. Heating does not expand, light weight, convenient construction, can be arbitrary shear bending, is the ideal energy saving material for furnace, pipeline and other thermal insulation equipment.
Application of ceramic fiber board
- Cement and other building materials industry kiln backing insulation
- Kiln backing insulation in petrochemical, metallurgy, ceramics and glass industries
- Heat treatment kiln backing insulation
- Non-ferrous metal industry backing insulation
- High temperature reaction, heating equipment backing insulation
