High Alumina Aluminum Silicate Fiber Cotton

High Alumina Aluminum Silicate Fiber Cotton – 62% Al₂O₃ High Alumina Refractory Fiber Wool, High Temperature Resistant Flexible Fill Thermal Insulation Material For 1200℃ Continuous Working Heat Treatment Furnace & Ceramic Kiln Inner Interlayer Gap Filling 1. Product Core Profile This high alumina aluminum silicate fiber cotton is a high-grade flexible loose-fill thermal insulation refractory, which has a completely different amorphous fibrous structure from rigid molded Refractory Brick, solid clay Firebrick, dense load-bearing High-Temperature Brick, integral furnace lining Kiln Brick, solid decorative Ceramic Brick and block-shaped porous Insulating Fire Brick. The finished material is produced by melting high-alumina batching raw materials and high-speed fiber blowing forming, with precisely controlled alumina mass fraction stabilized at 62%. A large number of ultra-fine disorderly interlaced fibers stack to form fluffy cotton texture filled with static air gaps, which can be…
