一、金属网顶棚抹灰产生质量问题的调查和分析金属网顶棚抹灰普遍存在着裂缝、空鼓、脱落等质量问题,它不仅影响美观和使用,而且不安全。鉴于上述原因,我公司先后对11个工程约3万多米~2各类顶棚进行了调查和分析,现按金属网顶棚不同抹灰层分述如下: 1.底层、找平层和罩面用纸筋混合砂浆。这种顶棚表面有很多的龟裂,裂缝在同一垂直面上贯穿至底层,但各层砂浆之间的粘结力较好,无空鼓声。一般用于浴室、厨房等有大量水蒸气的房间。当水蒸气通过贯穿的裂缝,大量渗透到顶棚里,使金
First, investigation and analysis of metal mesh ceiling plaster quality problems Metal mesh ceiling plaster commonly exists cracks, hollowing, falling off and other quality problems, it not only affects the appearance and use, but also unsafe. In view of the above reasons, our company successively investigated and analyzed about 30,000 meters~2 types of ceilings for 11 projects. We now divide the different plastering layers of metal mesh ceilings as follows: 1. For the bottom layer, leveling layer and covering Paper reinforced mortar. There are many cracks on the surface of the roof, and the cracks penetrate to the bottom layer in the same vertical plane, but the adhesion between the layers of mortar is good and there is no empty drum sound. It is generally used in bathrooms, kitchens and other rooms where there is a lot of water vapor. When water vapor passes through the cracks, it penetrates into the ceiling in large quantities, making gold
