The raw materials of rock wool mainly include selected natural high-quality basalt or diabase, as well as appropriate amounts of supplementary materials. These raw materials are melted at high temperatures, centrifugally blown, and finally made into mineral wool.
After the raw materials of rock wool are melted at high temperature, the internationally advanced four-axis centrifuge is used for high-speed centrifugation into fibers. At the same time, a certain amount of binder, dust-proof oil, and water-repellent agent are sprayed into the fiber, and then collected by a cotton collector and passed through the pendulum method. , coupled with the three-dimensional method of laying cotton, curing and cutting, to form rock wool products of different specifications and uses.
