摘　　要：提出大型砼基磷酸萃取槽内部防腐的一种新型式——采用预硫化丁基胶板作防渗层,以酚醛胶泥砌筑粗颗粒高灰分非浸渍碳砖作防磨层的防腐方案,介绍了预硫化丁基胶、粗颗粒高灰分非浸渍碳砖、酚醛胶泥的性能,总结了相关的施工方法和经验。The inner anticorrosion treatment for largescale concretebased extraction tank of phosphroic acid is presented, which is that the plate of precure butyl rubber is taken as antipercolator and the abrasionproof layer is built with phenolic daub adhering to nondipped carbon brick with high ash and coarse meal. The characteristics of precure butyl rubber, nondipped carbon brick with high ash and coarse meal and phenolic daub are described. The treatment and experience of anticorrosion construction are also summed up.
