多用酸洗缓蚀剂DSCH-1的研究

Preparation of Universal Corrosion Inhibitor for Acid Cleaning

由含氮的脂肪胺、芳香胺等多种常用的有机缓蚀剂复配制成的ＤＳＣＨ－１ 缓蚀剂，在硝酸中对２０＃ 锅炉钢和紫铜的缓蚀效率达９９．７％ ，在盐酸中对２０＃ 锅炉的钢的缓蚀效率达９８．５％ ，对紫铜的缓蚀效率也较高。Ｆｅ３＋ 离子浓度对ＤＳＣＨ－１

Universal Corrosion Inhibitor DSCH 1 for Acid Cleaning is compounded of multiple frequently used nitrogenous aliphatic amine and aromatic amine organic corrosion inhibitors.Efficiency of inhibition is 99.7% for 20#boiler steel and copper in nitric acid,98.5% for 20# boiler steel in chlorhydric acid,and superior for copper.Concentration of Fe 3+ has high influence on performance of Inhibitor DSCH 1。
