Product introduction of ceramic fiber board
Ceramic fiber board is aluminum silicate fiber board, which is made of refractory materials. Compared with the fiber blanket or felt that can maintain good mechanical strength after heating, this product is a fiber heat insulation product with stronger and supportable strength. Ceramic fiber board not only has good properties corresponding to the dispersed ceramic fiber surface, but also has hard texture, excellent toughness and strength, and outstanding wind erosion resistance.
Features of ceramic fiber board
Ceramic fiber board is an ideal energy-saving material for kilns, pipes and other thermal insulation equipment because of its non expansion heating, light weight, convenient construction, and free cutting and bending.
Applications of ceramic fiber board
- Back insulation of boilers in cement and other building materials industries
- Thermal insulation of furnaces in petrochemical, metallurgical, ceramic and glass industries
- Heat treatment and insulation of kiln back
- Non ferrous metal industry has insulation background
- High temperature reaction, heating equipment and other thermal insulation
