１．成膜物及其改性树脂的选择一种涂料性能的好坏，成膜基材起着重要作用，成膜物质直接决定涂层的耐化学介质性能和物理机械性能。作为高氯化聚乙烯涂料，其主要成膜物是高氯化聚乙烯。其氯含量应在６０％以上，从氯含量来看，高氯化聚乙烯似乎就是过氯乙烯。过氯乙烯涂料于
1. The choice of film-forming material and its modified resin The performance of a paint is good or bad. The film-forming substrate plays an important role. The film-forming material directly determines the chemical resistance and physical and mechanical properties of the coating. As a high chlorinated polyethylene coating, the main film forming material is high chlorinated polyethylene. The chlorine content should be above 60%. From the perspective of chlorine content, high-chlorinated polyethylene appears to be perchloroethylene. Perchloroethylene coatings on
