Rock wool is mainly made from natural ores such as basalt and dolomite as the core raw materials, together with appropriate amounts of coke, limestone and other auxiliary materials. Under the extreme high temperature of 1450℃ or even higher, these raw materials are completely melted, and then with the help of international advanced four-axis centrifuges, they are stretched into fine fibers under the action of high-speed centrifugal force.
At the same time, a specific amount of binder, dust oil, water-repellent agent is sprayed into the fibers, which are collected by the cotton collector, and then combined with the three-dimensional method of laying the cotton by the pendulum method, and finally cured and cut into various specifications and uses of rock wool products.
