Ceramic Fiber Blanket / Aluminum Silicate Fiber Blanket
Ceramic fiber blanket, also called aluminum silicate fiber blanket, is made from long special ceramic fiber, formed by strong double surface needling, increasing inter-weaving and tensile strength. It has a range of products: ordinary type, standard type, high-purity type, high-alumina type and containing zirconium type. The performance of these products has difference, and they are suitable for different working temperatures. The product can be used after optional cutting, by using high-temperature refractory adhesive when stick.
Technical Advantages:
1.Low heat conductivity and thermal capacity
2. Excellent thermal stability and shock resistance
3. Strong tensile resistance
4. Excellent heat insulation, fireproof and sound insulation
Applications:
1. Industrial kiln, heating device, high-temperature pipeline wall lining.
2. Heat insulation of electric boiler, steam turbine and nuclear electricity.
3. Wall lining of chemical high-temperature conversion unit and heating equipment.
4. Fireproof and heat insulation of tall buildings.
5. Heat insulation of kiln door and roofs, fire partition.
6. Fireproof rolling shutter door
