Rock wool board is made of high-quality natural rock as the main raw material, such as basalt, gabbro, dolomite, etc., with an appropriate amount of binder added, high-temperature melting and high-speed centrifugal solidification by a four-roll centrifuge. It is then collected on a collecting belt, pleated by hammering, solidified, and cut to form products of different specifications. It has the characteristics of non-flammability, low thermal conductivity, sound insulation, and good chemical stability. This product is widely used in metallurgy, electric power, chemical industry, construction, shipbuilding and other fields. It is an ideal material that is both economical and has good thermal insulation effect. The water repellency of waterproof rock wool products can reach more than 98%. Because it does not contain fluorine and chlorine, it has no corrosive effect on equipment. Products include: boards, felts, seam felts, veneer felts, belts, and shells and tubes.
