Q:The difference between rock wool and rock wool: Yanmian tube is a kind of rock wool insulation material mainly used in the pipeline. After the natural basalt is melted by high temperature, the artificial inorganic fiber is made from the high speed centrifugal equipment, and the special binder and dustproof oil are added. Temperature curing, made into a variety of specifications, different requirements of the rock wool insulation tube

Q:What role does dolomite play in rock wool products?: Polyurethane foam is a dense structure of the microporous foam, closed cell rate of 92% or more, with a smooth self-crust, is a good impervious material, in the construction of direct spraying molding technology, so Pu hard layer did not fight The overall formation of the entire impermeability of the seam, fundamentally put an end to the possibility of deepening the roof water from the seam

Q:Rock wool board is inorganic composite insulation material: Rock wool composite insulation material depends on what you compound the material

Q:Rock wool insulation material fire rating is how much: Rock wool products are: rock wool board, rock wool tube, rock wool felt, rock wool insulation and so on
