Aluminum Silicate Ceramic Fiber Blanket is made from long special ceramic fiber, formed by special strong double surface needling, without any binder ,increasing inter-weaving and tensile strength, so that ceramic fiber blanket own good stability under any working temperature.
Features：
♦Low thermal conductivity ,heat storage and heat capacity
♦Excellent heat insulation
♦Excellent chemical stability
♦Shock and chemical attack resistant
♦Low thermal conductivity and shrinkage
♦Resilience under working condition, Low shrinkage under high temperature
♦Excellent sound insulation and resistance of folding
Application:
♦Ceramic industry → Kiln car insulation and seal,contious and batch kiln
♦Steel industry → Heat treating and annealing furnace,furnace lining and seals,reheating furnace and ladle covers,furnace hot face repairs,soaking hit covers and repairs
♦Refing and petrochemical → reformer and pyrolisis lining,tube seals,gaskets and expansion joints,high temperature pipe,duct and turbine insulation. crude oil heater lining.
♦Power generation → Boiler insulation,expansion seals and covers insulation
♦Others → insulation of commercial dryers and ovens,refractory materials,glass furnace insulation,fire protection.
