Difference Between Glass Wool And Rock Wool

Different production materials and processes

Centrifugal glass wool is made of glass as the main raw material, mixed with other auxiliary materials in a certain proportion, and then sent to the glass furnace for full melting. After that, the melted solution flows out through the leakage plate and enters the centrifuge. Driven by the high-speed centrifuge, the centrifuge operates at high speed to throw the glass into a glass trickle. Under the action of high-temperature and high-speed flame, the glass trickle is further stretched into fibers, and then the atomized binder is applied. Under the action of negative pressure wind of cotton collecting mesh belt, the fibers attached with resin binder settle on the moving mesh belt to form a uniform cotton felt. Then, the curing process is completed through the constant temperature curing furnace, and the product is finalized, After finalization, it is cut into a predetermined product, and then packaged

Rock wool products are a new type of lightweight thermal insulation material, which is made of refined basalt as the main raw material, after high-temperature melting, inorganic fibers are made by high-speed centrifugal equipment, then special binder and dust-proof oil are added, felt is paved by swinging belt, fiber arrangement structure is changed by special equipment, and then cured According to different uses, it can be processed into rock wool board, rock wool joint felt, rock wool pipe shell and other products.
