外墙外保温材料体系的科学性问题探讨之三北京环益美高分子聚合物研究所周广德建筑外保温材料及其施工工艺,既要保证具有较高的保温节能效率,又要将保温节能工程与外墙装饰装修工程相结合,科学选材、用材,规范施工,确保工程质量。本文根椐保温节能工程的实际应用情况,对几种常用的外保温材料及工艺质量方面进行综合性的对比分析与研究。关键词外墙外保温保温材料保温节能技术世界人口己达到6亿,25年将突破1亿,我国人口已过13亿,25年将达到16亿,但人均能源占有量约为世界人均占有量三分,仅为美国人均占有量的百分之五,随着经济不断发展和生活水平的提高,我国资源消费量也在不断地增加,公共建筑和住宅楼除要一次性消耗大量的水泥、钢材、木材等建筑材料外,还要长期耗用大量的电能、热能,而水、电、煤、油这四大基础能源供需矛盾日益加剧,又特别是在经济发达地区,我国各级对建筑节能工作都十分重视,实行强制性推广政策,经过几年努力推广应用,己初见成效。
