This issue we will introduce the difference between rock wool insulation and glass wool.

     2. Raw material and production process
     Glass wool is made of glass as the main raw material, mixed with various auxiliary materials in a certain proportion, and then sent to the glass melting furnace to be fully melted, and the melted solution flows out through the drain plate and enters the centrifuge. Driven by the high-speed centrifuge, the glass is thrown into a thin glass stream, and then the high-temperature high-speed flame is used to further stretch the glass stream into fibers, and then apply atomized binder under the action of the negative pressure wind of the cotton-collecting mesh belt , The fiber attached with the resin binder settles on the moving mesh belt to form a uniform cotton felt. Then the curing process is completed in a constant temperature curing oven, and the product is shaped. After the shaping, it is cut into the product and then packaged .
     Rock wool insulation is made of refined basalt as the main raw material. After high-temperature melting, the melted raw material is made into inorganic fiber by high speed centrifuge. Then special binder and dust-proof oil are added to the fiber. And through the pendulum and special equipment the fiber arranging structure is changed. And after curing and shaping the light weight rock wool insulation products are formed. It can be processed into rock wool insulation board, rock wool insulation joint felt, rock wool insulation pipe shell and other products.
