Cheap Price Rock Mineral Wool Board 60-140kg/M³ Thermal Insulation 50mm 100mm Thickness
Leadsun rock wool products are made from natural rock such as basalt and dolomite. The natural rock are melted into melts in cupola at a very high temperature about 1500°C. And the melts lava is then pour to high speed spinners through which the melts get into fibers. At the same time, the phenolic binder containing silicon and mineral oil etc are sprayed onto the surface of each fiber homogeneously.
Rock wool products is base on superior melted basalt as the main raw material, through centrifuge system of four-roller cotton process which pulls melted basaltic rockwool into a 4 ~ 7μm non continuous fibers followed by adding a certain amount of binder,dust laying oil, water repellent before settlement folding, curing, cutting and other processes, and then made into the productsof different density depending on purpose of usage like blanket or board or pipe etc shapes .meanwhile it can be non-faced or faced with wire mesh. This material using in construction.Petroleum, electric power, chemical industry equipment’s thermal insulation and Building partition wall, curtain wall, roof and building envelope thermal insulation
