随着我国建筑节能事业的深入开展,全国大部分大中城市都在积极推广应用外墙外保温节能技术,一些相对成熟的保温体系(如聚苯板薄抹灰体系、聚苯颗粒保温砂浆体系等)开始得到广泛应用。但由于我国区域气候的巨大差异及保温系统的复杂性,外墙外保温工程中出现了很多开裂、剥落等质量问题,严重影响了建筑的形象。预防外墙外保温系统裂缝,保证外墙外保温系统的质量,已成为业内关注的焦点。
With the deepening of China’s building energy-saving undertakings, most large and medium-sized cities across the country are actively promoting the application of exterior insulation and energy-saving technologies. Some relatively mature insulation systems (such as polystyrene board thin plastering system, polystyrene particle thermal insulation mortar system Etc.) began to be widely used. However, due to the huge difference of regional climate in our country and the complexity of thermal insulation system, many problems such as cracking and spalling appear in the exterior thermal insulation project, seriously affecting the image of the building. To prevent cracks in the external insulation system to ensure the quality of external insulation system has become the focus of the industry.
