本文对大型不锈钢容器的表面化学处理,提出了比较合理的酸洗液配比成份,现场施工方案;进行了经处理后的不锈钢抗腐蚀性能的对比试验,并探讨了酸洗过程中的某些机理. In this paper, the surface chemical treatment of large stainless steel containers, put forward a more reasonable proportion of pickling ingredients, on-site construction program; conducted a comparison of the treated stainless steel corrosion resistance, and discussed the pickling process of some mechanism.
