What is the difference between aluminium silicate needled blanket and aluminium silicate fiber felt?
The aluminum silicate needled blanket is a kind of heat preservation refractory material which is made of aluminium silicate as raw material and made by the process of electric Yin furnace and made of long fiber of aluminum silicate. According to the production process, it can be divided into wire throwing needle blanket and injection acupuncture blanket. According to different raw materials and formulations can be divided into: ordinary type (STD), Gao Chunxing (HP), (HA), high aluminum zirconium aluminum type, standard type, with zirconia type (ZA).
Aluminum silicate needled blanket is made of high-quality coke stones by more than two thousand degrees Celsius temperature of melting and solidification into fusion with other additives and have many special properties, such as, good extensibility, strong shock resistance, light weight, excellent heat insulation, good stability, no deformation at high temperature to several thousand degrees, so aluminum silicate needled blanket is often used in the chemical industry, construction industry, electronic industry, aerospace industry, military industry, air conditioning and refrigeration etc..
White color, regular size, set fire-resistant, heat insulation, insulation in one, without any binders. When used for a long time in the neutral and oxidizing atmosphere, the aluminum silicate needle blanket can still maintain good tensile strength, toughness and fiber structure. The temperature is 950-1414 centigrade. It has chemical stability, thermal stability, sound absorption and noise reduction performance, high tensile strength, low thermal conductivity and low thermal capacity.
