water proof rock wool board Fireproof and waterproof Insulation and warm keeping rockwool, glasswool as core material 1. Introduction The rock wool products take basalt as its main raw materials, after the towering stove is melted, use high-speed acentric equipment to make basalt high-temperature melting body into inorganic fiber, and then put bond, polish, silicone oil in at the mean time. According to different requirements, we can manufacture kinds of products, such as rock wool board, rock wool pipe, rock wool blanket , rock wool elbow, tile, and so on. 2. Specification : (1)Density: 80-180kg/m3 (2)Specification:1000×600mm (3)Thickness:30-100mm (Special size can be made to order) 3. Performance: 1) Excellent thermal insulation, mechanical, fireproof and sound absorption property. 2) High acidity coefficient, good chemical stability and fiber durability. 3) Low cost and high temperature resistance. 4. Application It is widely used as thermal insulation material for high-temperature pipe, tank, equipment and vessel in petroleum, chemical and metallurgy industry. It can also be applied to partition, ceiling and building wall as thermal insulation and sound absorption material in construction industry. ***** data: Item Unit Specification Average diameter of fiber μm ≤7 Weight Kg/m3 80-180 Thermal conductivity w/m.k ≤0.044 Inflammable property Non-Inflammable Hydrophobic coefficient % ≥98 MaximumService temperature °C 650 Slag ball % ≤12 Organism % ≤3 Water % ≤0.5 Water absorption coefficient % ≤5
