建造冷库、大型蓄电池室等建筑时,需要涂刷冷底子油,进行“二毡三油”施工(即粘贴二层油毡,涂刷三层沥青)。在这种施工中往往存在有较大的火灾危险性。近年来,因此而发生的火灾事故已有过多起,如湖北武汉冷库、浙江普陀朱家尖冷库,江苏无锡冷库、上海石洞口电厂蓄电室等,在进行“二毡三油”施工中,都发生过重大火灾,造成了严重损失。发生这类事故的原因之一是配方不当,如朱家尖冷库用70%的汽油和沥青泪和配制冷底子油。而上海 Construction of cold storage, large battery room and other buildings, you need to brush the cold base oil, “two felt three oil ” construction (ie paste the two layers of linoleum, brushing three asphalt). In this kind of construction, there is often a big fire risk. In recent years, there have been too many fire accidents, such as cold storage in Wuhan, Hubei, Zhujiajian cold storage in Putuo, Zhejiang, Wuxi cold storage in Jiangsu, Shanghai Shidongkou power plant storage, etc., During the construction, a major fire broke out, causing serious losses. One of the causes of this type of accident is improper formulation, such as Zhujiajian cold storage with 70% of gasoline and asphalt tears and the preparation of cold base oil. Shanghai
