【摘要】 为了找到一种能够很好地抑制盐酸体系对铁或铜腐蚀的清洗缓蚀剂，进行了溴泠机盐酸体系化学清洗缓蚀剂对比实验，结果发现：苯胺与浓盐酸的体积比为３ ：４０ 时，缓蚀效果理想；苯胺与浓盐酸和水的理想体积比为０．３ ：１０ ：３０ 。根椐实验可以认为，苯胺是理想的酸洗缓蚀剂。更多还原

【Abstract】 In order to obain an effective corrosion inhibitor,the comparative experiments have been carried out for hindering the corrosion of Fe and Cu in chemical cleaning process with hydrochloric acid system for bromido refrigerators.The results show that when the volume ratio of aniline and cocentrated hydrohloric acid is 3∶40,the effect of corrosion inhibiting is satisfactory,while the volume ratio of aniline,concentrated hydrochloric acid and water is 0.3∶10∶30.So,aniline is the most effective corrosion inhibitor for the chemical cieaning by acid.更多还原
