Classification and process color steel sandwich panels currently used in more types are: Color polyurethane composite board, color steel polystyrene foam complex, polyethylene materials, phenolic foam foam plastic, three types of materials, straw board inorganic fibers wood wool panels. Plywood, composite panels Caigangyanmian rock wool insulation board production process: wool board is composed of basalt (slag) by the blast melted into a liquid, stick spun by high-speed centrifugation, color steel prices, the high-speed air flow blowing, complex board manufacturers, forming a small fiber fineness, flexibility and strong wool board fibers, injection Bumian law, composite panels, rock wool plate special synthetic rubber to be injected into the wool fibers, the wool fiber composite , rock wool composite panels, and then by constant speed pendulum, uniform cloth - cotton wool fiber Bumian method, the track speed control, track up and down compression, compressed into density rock wool board, rock wool board level by the track speed control, and pendulum fall cotton decision. After the wool after the pendulum Bumian by track up and down compression, transfer to a high temperature oven, which was dried, made into wool board
