The aluminosilicate felt is made of high-quality pyrogem, which is melted at a high temperature of more than 2000 ℃ and solidified with other additives, and then by injection or wire throwing process. It has many special properties, such as good extensibility, strong earthquake resistance, excellent heat insulation, light weight, simple construction, easy operation, green environmental protection, harmless to human body and strong stability, It is often used in the construction industry, chemical industry, electronic industry, aerospace industry, military industry, air conditioning and refrigeration and other fields.
White color, regular size, set fire resistance, heat insulation, insulation in one, without any bond. It has chemical stability, sound absorption and noise reduction performance, thermal stability, high tensile strength, low thermal conductivity and low heat capacity. When used in neutral and oxidizing atmosphere for a long time, the aluminosilicate needle punched blanket can still maintain good tensile strength, toughness and fiber structure.
The instantaneous temperature resistance of the aluminosilicate felt is 1050-1400 ℃. Long term temperature resistance is 950-1350 ℃.
High temperature thermal insulation of steel, petrochemical and electric power;
Wall lining of industrial high temperature reaction equipment and heating equipment, special-shaped pipeline, industrial furnace wall lining, stress relieving heat insulation metal casting, stress relieving heat insulation, roof insulation of household door
Aluminum silicate felt can be divided into five grades: ordinary type, standard type, high purity type, high aluminum type, zirconium aluminum type and zirconium containing type. The bulk density ranges from 80-128 kg / m3. Thickness from 10-50mm, to meet the needs of customers under different temperatures and different requirements of insulation.
