摘　　要：湿式储气罐的腐蚀原因主要是涂料涂层部位和漏涂部位钢板形成的大阴极和小阳极之间局部腐蚀。提出采用超粘附长效防腐涂料作为底漆、环氧树脂高氯化聚乙烯涂料作为外壁涂料、环氧橡胶煤沥青玻璃鳞片涂料作为内壁涂料,进行涂层防护。The main reason of corrosion of watersealed gasholder is that the partial corrosion is formed between cathode and anode due to the difference between coating and uncoated position in the individual part of steel sheet. It can prolong the watersealed gasholder life that hyperploid conglutination and lastingeffect anticorrosive paint is used as priming, epoxy resin and high chlorinated polyethylene paint is used as outside paint, and epoxyrubbercoal tar paint is used as inside paint.
