Product description of ceramic fiber board
Ceramic fiber board is a material made of aluminum silicate fiber cotton, which is then finely processed into ordinary ceramic fiber board by vacuum forming or dry forming, drying and pressing.
Features of ceramic fiber board
The ordinary type has the same performance as the corresponding loose aluminum silicate fiber cotton. The product has hard texture, high toughness and strength, and good wind erosion resistance. It is light in texture, does not expand during heating, and is convenient for construction. It can be cut and bent at will. It is an ideal energy-saving product for furnace pipes and other insulation equipment.
Advantages of ceramic fiber board
Low heat conduction and capacity.
High compressive strength and good toughness.
Good thermal stability and tensile impact properties.
Application of ceramic fiber board
Ceramic fiber board is suitable for industrial kiln wall lining and masonry insulation layer; Thermal insulation layer of high-temperature equipment; High temperature kiln lining; Kiln car protection door baffle and furnace insulation plate.
