Product overview:

It is a kind of fibre-board product with fixed strength and hardness, which is made from ceramic fiber after deslagging with different proportions of inorganic binder and organic binder by vacuum filtration or mechanical filtration forming and drying. At present,the common ceramic fibre board has aluminum silicate ceramic fiber board and ultra-high temperature polycrystalline alumina fiber composite board.

Aluminum silicate ceramic fiber board

It is aluminosilicate fibre board. This product maintains good mechanical strength even after heating. Ceramic fibre board can withstand the high temperature of more than 1000℃. Referring to the specific data, even if the product with low density, it’s refractoriness can also reach 1260℃, this temperature is enough to melt the steel. And the product with a higher density, it can withstand more than 1400℃ high temperature, and can be used in coal-fired boilers. According to the working temperature, aluminum silicate ceramic fiber board can be divided into: general aluminum fiberboard, standard fiberboard, high purity fiberboard, high aluminum fiberboard and fiberboard containing zirconium, In addition to have the excellent performance of the corresponding bulk ceramic fiber, ceramic fibre board is hard, toughness and strength, has an excellent ability of wind erosion resistance , non-expansion after heating, light weight, convenient construction, can be cut and bend arbitrary. It is an ideal energy saving material for kiln, pipe and other insulation equipment.

Ultra-high temperature polycrystalline alumina fiber composite board

Ultra-high temperature polycrystalline alumina fiber composite board adopts polycrystalline alumina fiber as the main raw material, combined with padding and adhesive, etc., to be formed by combined method of suction and pressure . Compared with the calcined fiber products on the market, Ultra-high temperature polycrystalline alumina fiber composite board has the advantages of good processability, low thermal conductivity and low bulk density. Especially the FHB1800 ceramic fiberboard and special-shaped products can meet the requirements of high temperature 1800℃ and can service under 1700℃ for a long time, and have been used in many kilns instead of imported products, with good energy saving results and reduced use cost.
