长期以来,卷材防水层都采用热沥青或热沥青玛(?)脂来铺贴,既不安全,又不容易保证工程质量。屋面漏雨,地下室漏水,成为建筑工程质量通病之一。尤其是地下工程潮湿,通风不良,并且要立面铺贴卷材,操作难度大,劳动条件差。因此,防水工人很早就盼望改变这种落后的施工工艺,变热法作业为冷法作业。目前,这种希望已开始变为现实。 For a long time, the waterproofing layer of coils has been paved with hot asphalt or hot asphalt, which is neither safe nor easy to guarantee project quality. Leaking roofs and leaking in the basement have become one of the common problems in the quality of construction projects. In particular, the underground works are humid and poorly ventilated, and it is difficult to lay the membranes on the facades. The operation is difficult and the working conditions are poor. Therefore, waterproof workers have long been looking forward to changing this backward construction process, and the thermal operation is a cold operation. At present, this hope has begun to become a reality.
