Ceramic fiber blanket is flexible ,high quality ,heat preservation and thermal insulation material . Ceramic fiber blanket has many merits like small thermos table bulk density ,low heat conductivity ,good heat preservation performance ,easy cut and constructed heat preservation and insulation inside lining of furnaces . It has been exported to Malaysia ,Iraq etc .
Features:
1\Low heat storage ,Low thermal conductivity
2\Excellent insulation ,good sound absorption
3\Excellent chemical and thermal stability .
Production Technique :
Ceramic Fiber Felt are manufactured in a wet vacuum forming process by blending the chopped ceramic fiber with inorganic or organic binders for excellent abrasive resistance at high temperature .The process of production is automatic control by PLC ,and once forming .
