摘要
利用ＤＪＳ－２９２型恒电位仪测定碳钢于酸洗溶液中的阳极极化曲线，以比浊定量法测定酸雾含量。结果表明，缓蚀剂（ＣＡ）抑雾作用强，耗酸量低，加速酸洗速度，无过腐蚀现象，缓蚀效率可达９６％。ＣＡ组成（％）：酒石酸２．５～３．５，硫脲２～４，抑雾剂２．０，苯胺０．５～２．０，表面活性剂２．０，Ｃｌ－０．５～１．０，水余量。ＣＡ属于混合抑制型缓蚀剂。
AbstractAnodic polarization
curves of carbon steal in sulphuric acid solution have been examined by constant potential
measurement, and the acid fog contents in the air by a quantitative method of comparative
turbidity. The results showed that the inhibitor can strongly restrain the acid fog and accelerate
acid washing rate. The inhibition efficiency could reach 96%.
