近年来,因外墙涂料具有美观大气、施工方便及施工速度快等优点越来越多被用于各种工程当中。但有不少工程投产后甚至投产前就发现有很多裂纹,其大小、深浅、形状各异,严重影响建筑物外墙效果,有的还产生渗漏等影响到使用功能。这是因为外墙涂料与传统的装饰材料(如外墙砖等)相比抗裂性能较差。为了减少和杜绝上类施工质量通病,现特别从预防、施工及裂纹处理几个方面进行探讨研究。
In recent years, due to the beautiful appearance of the outer wall paint, construction convenience and construction speed advantages such as more and more being used in a variety of projects. However, many projects have even found many cracks before they are put into production. Their size, depth and shape are different, which seriously affect the external wall effect of the building and some also cause leakage and affect the use function. This is because the exterior paint is less crack resistant than conventional decorative materials such as exterior walls. In order to reduce and eliminate the common problems of the quality of the construction of the upper class, the study is especially carried out from the aspects of prevention, construction and crack treatment.
