国家经贸委与有关部门推出了节能建筑与新型墙体材料应用技术。它主要指建筑围护结构节能技术与新型墙体材料的应用,是建筑节能、节材的基本组成部分。其主要内容是加强围护结构的保温隔热,提高其气密性,采用保温隔热性能良好的新型体材料。包括:①聚苯外保温复合墙体:在以砖墙、砼墙或砌块墙为主体结构的外墙面上覆聚苯保温层和保护饰面,其主要性能指标满足国家标准要求,墙体传热系数可以达到0.70～0.40W/m~2·k,并解决了墙面开裂、空鼓等问题。②砼空心砌块:利用陶粒、浮石等轻骨料或炉渣等工业废料生产多排孔空心非承重砌块,密度小,保温性能好,也可用做成承重空心砌块和一次成型的保温隔热带饰面的外墙砌
The State Economic and Trade Commission and relevant departments have introduced energy-saving buildings and new wall material application technologies. It mainly refers to the building envelope energy-saving technology and the application of new wall materials, is the building of energy-saving, material-saving part of the basic components. Its main content is to strengthen the thermal insulation of the envelope structure, improve its airtightness, and adopt new body materials with good thermal insulation properties. Including: 1 Polystyrene exterior thermal insulation composite wall: covering benzene insulation layer and protective veneer on the external wall surface with brick wall, concrete wall or block wall as the main structure, and its main performance indicators meet the requirements of national standards. The body heat transfer coefficient can reach 0.70~0.40W/m~2k, and solve the problem of wall cracking and hollowing. 2. Hollow hollow blocks: The use of ceramic aggregates, pumice stones and other industrial waste materials such as lightweight aggregate or slag to produce multi-row hollow hollow non-load-bearing masonry blocks, low density, good insulation properties, can also be used as a bearing hollow block and a molding insulation Heat-insulated exterior wall cladding
