Description of Ceramic fiber board:
Ceramic fiber board is a lightweight refractory material processed with alumina-silica fibers for applications at temperatures up to 1430C. it manufactured and designed for the thermal applications
requesting high demands on rigidity, the thermal insulation properties and abrasion resistance of ceramic fiber board have been further improved due to the higher density. Ceramic fiber board is a
vacuum formed product that resists higher gas velocities than ceramic fiber blanket. It is ideal for furnace, boiler duct and stack lining thanks to its low thermal conductivity and low heat storage,
which makes the shorter cycles times and quicker access for maintenance in the industrial furnaces possible.
Feactures of Ceramic fiber board:
1. With small heating line change
2. Low slag ball content, outstanding refractory and thermal insulation properties
3. Excellent heat reflection performance
4. Low heat storage and low thermal conductivity
5. Uniform fiber diameter, high tensile strength
6. Strong wind corrosion resistance
7. Good high temperature flexibility, excellent thermal shock resistance and mechanical vibration performance
8. Stable chemical properties, strong erosion resistance
