岩棉及其制品是目前世界上发达国家中应用最多,效果最好的新型保温建筑材料.它与传统的保温材料相比,具有容重轻、导热系数小、不燃不腐、不蚀、耐热、保温,使用温度范围大、使用周期长等优点。同时岩棉制品安装方便,便于施工,还有优良的吸音性能,节能效果显著,因而具有广阔的市场. 但是,由于一般岩棉生产线一次性投资较大,如北京新型建材厂引进一条瑞典的岩棉生产线需人民币4000万元,生产原料运输距离远,费用高,该厂从张家口运来一吨玄武
Rock wool and its products are the newest type of thermal insulation construction materials that have been most widely used in developed countries in the world and have the best effect. Compared with traditional thermal insulation materials, they have light weight density, low thermal conductivity coefficient, no burning, no corrosion, no corrosion, and heat resistance. , Insulation, use temperature range, long life cycle and other advantages. At the same time, rock wool products are easy to install, easy to construct, and have excellent sound-absorbing properties, which have significant energy-saving effects, and thus have a broad market. However, due to the large one-time investment in general rock wool production lines, such as the introduction of a Swedish rock in Beijing New Building Materials Factory. The cotton production line needs RMB 40 million, the production materials are transported far away and the cost is high. The factory shipped a ton of basalt from Zhangjiakou.
