由上海建筑科学研究所和上海燎原化工厂共同研制生产的LP—37薄膜养护剂已在葛洲坝工程上正式应用,效果很好。LP—37薄膜养护剂是以氯乙烯、偏氯乙烯的单体为主要原料,加入一定量的乳化剂、引发剂、还原剂共聚而成的一种高聚物的乳状液。外观为乳白色,无毒,不燃,pH值2～3,含固量43～45％,最低成膜温度不小于5℃,贮存6个月无变化。这种养护剂喷洒在新浇好的混凝土面上,可以形成一层致密
The LP-37 film curing agent co-developed and produced by the Shanghai Institute of Building Research and Shanghai Ebara Chemical Plant has been formally applied to the Gezhouba Dam Project and has achieved good results. LP-37 film curing agent is a kind of high polymer emulsion obtained by copolymerizing a certain amount of emulsifier, initiator and reducing agent with the monomers of vinyl chloride and vinylidene chloride as the main raw materials. Appearance is milky white, non-toxic, non-flammable, pH 2 ~ 3, solid content of 43 ~ 45%, the minimum film formation temperature of not less than 5 °C, storage for 6 months no change. This curing agent is sprayed on the surface of fresh concrete to form a dense layer
