Aluminum silicate fiber mat, also known as ceramic fiber mat, belongs to ceramic fiber board with smaller volume density.
The aluminum silicate fiber felt is made of selected high-quality coal gangue melted in an electric furnace above 2000 ℃, sprayed into fiber, and uniformly added with special adhesive, oil repellent and water repellent after heating and curing. The length of the filament aluminum silicate fiber felt is 5-6 times that of the ordinary aluminum silicate fiber, and the thermal conductivity can be reduced by 10-30% at the same density.
Specification and size: the conventional size of aluminum silicate fiber felt is 900 * 600 * 10~50mm; The bulk density is 160-250kg/m3.
The aluminum silicate fiber blanket (ceramic fiber blanket) is flexible and rolled. It is made of selected high-quality coal gangue melted in an electric furnace above 2000 ℃, sprayed into fibers, and then punched, heat treated, cut, and rolled. The fibers are evenly woven, with high tensile strength and without any binding agent.
The conventional size of aluminum silicate fiber blanket is (3000-28000) * (610-1200) * 6~60mm; The bulk density is 80-160 kg/m3.
Both continue the advantages of aluminum silicate fiber: white color, low thermal conductivity, insulation and compression resistance, chemical stability and elasticity. They are processed by different processes. They are often used as wall lining and backing of industrial furnaces and heating devices, high-temperature gaskets and expansion joints.
