Belte rock wool blanket takes selected high-quality basalt as the main raw material. After melting the day after tomorrow, it adopts the international advanced four stick centrifugal cotton making process to swing the high-temperature melt of basalt into 4-7 μ m discontinuous fiber, and then add a certain amount of adhesive, anti-dust oil and hydrophobic agent to the rock wool fiber. After sedimentation, solidification, cutting and other processes, it is made into products with different densities according to different purposes.

Application: thermal insulation, sound absorption and noise reduction of equipment in petrochemical industry, petroleum, electric power and chemical industry. Partition walls, curtain walls, roofs and maintenance of thermal insulation, sound absorption and noise reduction in the construction industry.
