Rock Wool
Rock Wool is produced by melting mix of basalt,limestone&coke in a special vertical furnace at very high temperature(about1500°C).Then the molten rock is made into thin fibers through a high speed centrifugal machine. After adding certain amount of binder,dust proof oil,silicon oil and mechanical operations,rock wool fibers are then processed to be the final desired product with specified physical and chemical Properties and specifications.
