目前,在屋面工程中卷材屋面的应用比较广,但还存在一个比较突出的问题,没有很好解决。问题是,由于低温和潮湿的影响,卷材屋面保温层中的水份不易蒸发,水泥砂浆层的强度降低,造成卷材铺贴不牢,无法保证施工质量。在我国北方的不少地区,低温季节一般占五个月以上。在这个时期内,无法进 At present, the application of coiled roofing in roofing projects is relatively wide, but there is still a rather outstanding problem that has not been solved. The problem is that due to the influence of low temperature and humidity, the moisture in the coil roof insulation layer is not easy to evaporate, the strength of the cement mortar layer is reduced, and the coil laying is not secure, and the construction quality cannot be guaranteed. In many areas of northern China, the cold season generally accounts for more than five months. During this period, it is impossible to enter
