Aluminum silicate needled blanket is a kind of heat preservation refractory material made of aluminum silicate long fiber needled by resistance furnace process.
According to the different production technology, it can be divided into spinning needle blanket and blowing needle blanket.
According to the different raw materials and formulations can be divided into: common type (STD), high purity type (HP), high aluminum type (HA), zirconium aluminum type, standard type, zirconium containing type (ZA).
Product characteristics
Aluminum silicate needled carpet is made of high quality coke gems melted at more than two thousand degrees Celsius and fused with other additives. It has many special properties, such as good extensibility, strong shock resistance, light weight, excellent heat insulation, strong stability, and no deformation at several thousand degrees high temperature. Therefore, aluminum silicate needled blankets are often used in the chemical industry, construction industry, electronics industry, aerospace industry, military industry, air conditioning and refrigeration and other fields.
advantage
White color, regular size, set fire, heat insulation, heat preservation in one, does not contain any binding agent. When used in neutral and oxidizing atmosphere for a long time, the aluminum silicate needled blanket can still maintain good tensile strength, toughness and fiber structure. The temperature is 950-1400ºC. With chemical stability, thermal stability, sound absorption and noise reduction performance, high tensile strength, low thermal conductivity; Low heat capacity.
