Alumina silicate boards are produced by melting bauxite at over 2000℃ in an electric furnace, then mechanically spun into fibers and uniformly mixed with a specially formulated binder, anti-oil agent, and water-repellent agent, which are then cured through heating. They are mainly used for thermal insulation in the power industry, electric boilers, steam turbines, and nuclear power plants; fire and thermal insulation in shipbuilding; construction, fire-resistant doors; as wall linings for high-temperature reaction equipment and heating devices in the chemical industry; in the automotive and train manufacturing industries; fire and thermal insulation; kiln lining; and roof sealing.
