从有关方面获悉,防水密封材料、保温隔热材料将成为下世纪我国建材发展的两个重要方向,前景看好。1．防水密封材料1996年我国新型防水卷材产量达4800万m~2,约占防水卷材总量的7%,市场占有率达到16%。其中,改性沥青油毡2860万m~2、高降物卷材1940万m~2。今后在我国防水密封材料领域,一方面要进一步加大新型防水材料的生产和推广应用,在提高技术 It is learned from relevant parties that waterproof sealing materials and thermal insulation materials will become the two important directions for the development of China’s building materials in the next century, and their prospects are promising. 1. Waterproof sealing material 1996 China’s new waterproof membrane production reached 4800 million m 2, accounting for about 7% of the total volume of waterproofing membrane, the market share of 16%. Among them, the modified asphalt felt 28.6 million m ~ 2, dropping objects coil 19.4 million m ~ 2. In the future in our country waterproof sealing materials, on the one hand to further increase the production of new waterproof materials and promote the use of technology
