Product overview:
Bulk Ceramic fiber（Bulk Aluminum silicate ceramic fiber ）：
It is also called bulk aluminum silicate ceramic fiber. It is made of high quality raw materials through melting and blowing or swinging process. Bulk Ceramic fiber are divided into ordinary, high aluminum, high purity and zirconium containing fiber, suitable for different service temperatures.
Bulk aluminum silicate fiber is a kind of product with low thermal conductivity, excellent thermal stability and chemical stability, no binder and corrosive substances. It always used for interlayer filling of equipment, fiber castable material, and raw material of daub material, vacuum forming product , etc.
It is a kind of new lightweight refractory materials, the material has the advantage of light weight, high temperature resistance, good thermal stability, low thermal conductivity, low heat capacity, good resistance to mechanical vibration, small thermal expansion, good thermal insulation performance. It can be made into ceramic fiber board, ceramic fiber felt, aluminum silicate fiber rope, ceramic fiber blanket, etc. through special processing. This new sealing material has character of low heat conductivity, light bulk density, long service life, high tensile strength, good elasticity, non-toxic point, is a new material to replace asbestos, and widely used for the heat insulation of equipment in metallurgy, electricity, machinery, chemical
Bulk Polycrystalline alumina fibre:
Bulk Polycrystalline alumina fiber is made by sol-gel method, which has advantages of small bulk density, low thermal conductivity, good thermal shock stability, high temperature, good chemical stability and good corrosion resistance. It is widely used in metallurgy, building materials, ceramics, aerospace and military industries.
