2000 Degree Refractory Ceramic Fiber Boards Polycrystalline Mullite Fiber Board for Furnace and Kiln Insulation Material
Polycrystalline Mullite Fiber Board Description
Polycrystalline mullite fiber board is a kind of rigid polycrystalline alumina fiber products prepared by special process by mixing polycrystalline alumina fiber wool with inorganic refractory aggregate, inorganic refractory powder and kind of additives in a fixed ratio, which can be reprocessed into various shapes and sizes of rigid shaped products by drilling and milling equipment.
Feacture of Polycrystalline Mullite 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
9. Easy to be molded and cut
Application
1.High-temperature laboratory
2.High-temperature furnaces and kilns
3.Aerospace industry
4.Back-up insulation to dense refractory linings
5.Expansion joints
6.High temperature sealing gasket
7.Anti-scour parts of lining inner paste
8.Hot surface material of high temperature furnace lining
9.Heating device thermal insulation
10.Furnace door and body filling material
