我公司自1986年第一次在上海缝纫机台板厂危险品仑库采用851焦油聚氨酯屋面防水涂膜施工了一百平方米以后,至今已用于五十多个单位工程、二万七千余平方米,其中有许多是建筑面积在一万平方米左右的高层建筑,如市政协、锦沧文华大酒店、新锦江、华东电力大楼、文汇报新闻业务大楼、华山医院、华东医院等市内著名的建筑物。由于851是液态冷作业,施工时毋需再在现场熬煮沥青,因此减少了环境污染,有利操作工人健康,而且施工后形成整体的无缝防水膜,易于达到整体防水效果,故自使用这一新颖防水材料代替传统的卷材屋面后,很受设计和施工人员欢迎,使用面迅速扩大,目前我公司所施工的工程除了造价较低的多层工房和少数建设单位嫌851造价太高而未选用外,其余工程基本上选用了851作为屋面防水材料。
Our company has used 851 tar polyurethane roof waterproofing membranes for the first time since it was built in Shanghai in 1986. It has been used in more than fifty units and more than 27,000 units. Square meters, many of which are high-rise buildings with a building area of about 10,000 square meters, such as the CPPCC, Jinhua Mandarin Hotel, Xinjinjiang, East China Electric Power Building, Wenhui News Business Building, Huashan Hospital, Huadong Hospital and other cities Famous building. Because 851 is a liquid cold operation, it is not necessary to cook the asphalt at the site during construction. This reduces environmental pollution and facilitates the operation of workers’ health. Moreover, after the construction, a seamless waterproof membrane is formed and the overall waterproof effect is easily achieved. After replacing the traditional roll roof, a new type of waterproof material was welcomed by design and construction personnel. The use of the surface was rapidly expanded. Currently, the construction cost of our company is too high, besides the low-cost multi-storey workshop and a small number of construction units. Without selection, the rest of the project basically chose 851 as roofing waterproof material.
