Hard Rock wool roofing panels with a light weight, small thermal conductivity, good sound absorption performance, good non-flammable, chemical stability. Rock wool insulation board wall insulation rock wool board, wall insulation rock wool board is a new type of insulation, burning compartment, sound-absorbing material. Rockwool products in addition to a general with the characteristics of wool, but also has a waterproof, heat insulation separated from the cold and other properties, there is a certain chemical stability, even if long-term use in wet conditions will not occur deliquescence. The method according to JISA9512-1979 test, the water-repellent rate of 98 or more. Because of its product does not contain fluorine (F-), chlorine (Cl-), and therefore its equipment without corrosion. Ministry of Public Security in Tianjin Fire Research Institute tests identified as non-combustible material. In 2002 the introduction of high-tech automatic mineral wool plate production line with an annual capacity 12500m3, rock wool board is widely used in shipbuilding, metallurgy, electricity, construction and other industries. The product construction and installation convenience, energy-saving effect is remarkable, with high performance and low cost. Marine and water-repellent wool insulation board in the production of water-repellent additive added, with good moisture resistance. Thermal insulation and fire cut wool board ship for ship; water-repellent wool board for vehicles, mobile equipment, cold storage, air conditioning ducts and fire insulation in humid environments, and there are certain requirements for moisture applications. Building rock wool board with excellent fire protection, thermal and acoustic performance. It is mainly used for building walls, thermal insulation of the roof; building walls, firewalls, fire doors and the elevator shaft of fire and noise. For electric power, petroleum, metallurgy, shipbuilding industry, pipe insulation and heat insulation, in particular to facilitate the rapid construction of small mouth straight pipe. Special features waterproof wool tube with moisture, exhaust temperature, water-repellent, particularly suitable in rainy, humid environment, moisture absorption rate of 5%, 98% or more water-repellent. Marine rock wool insulation panels and water-repellent wool insulation board in the production of water-repellent additive added, with good moisture resistance.
