Zhang Jia-bing, Chen Qiang
Abstract: with the continuous improvement of building energy efficiency technology, all kinds of building insulation materials such as bamboo shoots, which expanded perlite insulation board as developed in recent years a new type of building insulation materials, with its light weight, high strength, heat preservation and simple production process, flame retardant and low cost a lot of advantage, begin to be accepted by the market and gradually promoted and applied. In this article, through the expanded perlite insulation board compared with other thermal insulation material, the brief analysis of the characteristics of the expanded perlite insulation board, discusses its application in the building energy conservation and development direction in the future.
Key words: building energy-saving expanded perlite insulation board
引言
随着人民生活水平的不断提高及新型城镇化进程的加快,使得我国建筑能耗日益增长,并成为今后能源消耗的一个主要增长点。据统计,目前建筑在建造及使用过程中所产生的能耗已占据社会总能耗的1∕3以上。当前,资源紧缺与环境污染问题已成为制约国民经济发展的主要问题,近年来,出现在国内多数地区的持续雾霾天气,很大程度上凸显出了能源问题对环境的影响。因此,伴随着国家节能减排政策的深入推进,建筑节能也将朝着更严、更高的标准发展。
据统计,外围护结构所散失的热量大约占建筑热量损失的70%,其中又以外墙保温对整个外围护结构保温性能影响最大,不断提高墙体保温隔热效果,对提升建筑节能水平有着重要意义。长期以来,相关企业围绕外墙保温材料开展了深入的研究与探索,一些新的产品及技术不断被开发和应用,虽然种类及名称各异,但从本质上看,保温材料仍以浆料及板材两大类为主,目前,市场上常见的有XPS板、EPS板、岩棉板、膨胀珍珠岩保温板及玻化微珠保温砂浆等。……
