我国采用外墙保温技术已有多年历史了。能够满足节能50%、节能65%设计标准要求或更高节能标准要求。但是,从目前已完工的墙体保温工程质量情况看,无论是墙体外保温工程,还是内保温以及夹芯保温工程都存在不同程度的质量问题,如耐久性不强、裂缝、结露霉变、鼓涨脱落等,其中裂缝问题最为突出。 China has adopted wall insulation technology for many years. To meet the energy-saving 50%, 65% energy-saving design standards or higher requirements for energy-saving standards. However, from the current situation of the quality of the wall insulation project that has been completed, no matter whether it is a wall insulation project, an internal insulation or a sandwich insulation project, there are various quality problems such as poor durability, cracks, Change, drum up off, etc., of which the most prominent crack problems.
