1，production technical
thermal insulation basalt Rock Wool Basalt Fiber Insulation with high-quality basalt as the main raw material, after melting it,
through high-temperature spunning basalt wool into 4~7 μm non continuous
fiber with internationally advanced four-roll centrifugal wool production
technology, adding a certain amount of binder, dust laying oil and
moisture repellent into rock wool fiber, and after technologies of sedimentation, solidification, cutting, etc., the rock wool board are manufactured into series
of products with different density
