卷材满粘在砂浆基层上，因基层裂缝，导致卷材零延伸而断裂。不上人的屋面，保护层质量很轻，压不住空铺的卷材，为了防止大风吹起卷材，必须满粘法粘贴卷材，但又要防止零延伸，所以必须采取一些措施，既要满粘，又要避免零延伸。１改善基层砂浆的性能卷材的零延伸破坏是... The coils are stuck on the mortar base layer, and cracks in the base layer cause the coils to extend and break. Without the roof of a person, the quality of the protective layer is very light, and it cannot withstand the pressure of the empty sheet. In order to prevent the wind from blowing up the coiled material, the coil must be pasted with a full-stick method. However, zero elongation must be prevented. Therefore, some measures must be taken. It must be full of stickiness and zero elongation. 1 to improve the performance of the base mortar zero extension of the coil damage is ...
