以水泥或石膏为胶结材料,拌合膨胀珍珠岩,在现场浇筑成整体的保温隔热层,这种方法易于操作,但价格高,保温效果也差。因此,在北方严寒地区,较多采用的方法是将膨胀珍珠岩以松散状态铺设在屋面,形成屋面保温隔热层。如果操作方法得当,屋面保温效果比较好。根据我多年的工程实践经验,散铺珍珠岩保温屋面施工时,有以下几点必 Using cement or gypsum as a cementitious material, mixing expanded perlite and pouring it into an integral thermal insulation layer at the site, this method is easy to operate, but the price is high and the insulation effect is also poor. Therefore, in the severe cold regions of the north, the most commonly used method is to lay the expanded perlite on the roof in a loose state to form a roof thermal insulation layer. If the method of operation is appropriate, the roof insulation effect is better. According to my many years of engineering practice experience, when spreading perlite insulation roof construction, the following points must be
