What is ceramic fiber board
Ceramic fiber board is made of ceramic fibre cotton, a small amount of natural refractory materials and organic binders as the main raw materials, and is processed by a fully automatic control continuous production line. Ceramic fiber board is aluminum silicate fiber board, which is made of refractory materials. Even after heating, it still maintains good mechanical strength. Compared with fiber blanket and felt, this product is rigid and has supporting strength. The main raw materials are coke gem and aluminum oxide powder.
Features of ceramic fiber board
Ceramic fiber board products have high fiber content, high temperature, light weight, thermal shock resistance and other characteristics.
