防火岩棉板
Fire prevention board
岩棉板主要以经摆锤法生产的憎水型岩棉板为保温隔热层材料,岩棉复合板是以天然岩石如玄武岩、辉长岩、白云石、铁矿石、铝钒士等为主要原料,加适量的粘结剂、憎水剂经高温熔化、纤维化而制成的无机质纤维,其执行标准是GB/T25975-2010《建筑外墙外保温用岩棉制品》;矿渣岩棉棉是以工业矿渣如高炉的矿渣、磷矿渣、粉煤灰等为主要原料,经过重熔纤维化而制成的无机质纤维。市场上主要的A级防火外墙外保温系统介绍 (以下文字选自中国建筑标准设计研究院《外墙外保温建筑构造》标准号10J121)其执行标准是GB/T11835-2007《绝热用岩棉、矿渣棉及其制品》。
Rock wool board is mainly made of water-repellent rock wool board produced by pendulum method as insulation material. Rock wool composite board is made of natural rocks such as basalt, gabbro, dolomite, iron ore, aluminium vanadium, etc. as main raw materials, with appropriate amount of binder and water-repellent agent melted at high temperature and fibrosis. The standard is GB/T 25975-2010 "Rock wool products for exterior insulation of building walls". Slag rock wool is an inorganic fiber made from industrial slag such as blast furnace slag, phosphorus slag, fly ash and other main raw materials through remelting and fibrosis. The main A-level fire exterior insulation system on the market is introduced (the following text is selected from the Chinese Academy of Architectural Standards Design and Research Standard No. 10J121). Its implementation standard is GB/T11835-2007 "Rock wool, slag wool and its products for insulation".
岩棉复合板与矿渣岩棉板统称为矿物棉,矿渣棉在20世纪70年代开始广泛的用于冶金、机械、建材、石油、化工工业,岩棉用于外墙保温在国外发达国家如欧盟 已有近30年的历史,而在我国 由于其生产成本及 造价较高,经济成本大于有机保温材料,使其运用的范围不大
Rock wool composite board and slag rock wool board are collectively called mineral wool. Slag wool has been widely used in metallurgy, machinery, building materials, petroleum and chemical industry since 1970s. Rock wool has been used for external wall insulation in developed countries such as the European Union for nearly 30 years. But in China, because of its high production cost and cost, it is economically successful. The cost is larger than that of organic thermal insulation material, so that its application scope is not large.
