多功能酸洗缓蚀剂缓蚀效果的研究

对威海翔宇环保科技股份有限公司研发的多功能酸洗缓蚀剂进行了盐酸酸洗、H_2SO_4酸洗、硝酸酸洗缓蚀实验,实验结果表明,多功能酸洗缓蚀剂在盐酸酸洗、H2SO4酸洗、硝酸酸洗过程中对碳钢、16mn钢都有很好的缓蚀效果,加药浓度不同,缓蚀效果不同。多功能酸洗缓蚀剂的加药浓度一般在3‰~5‰,10%的盐酸酸洗的缓蚀率可达到98.8%、10%的H_2SO_4酸洗的缓蚀率可达到99.8%、10%的硝酸酸洗的缓蚀率可达到77%以上。

Research on Inhibition Effect of Multi-function Pickling Corrosion Inhibitor

Hydrochloric acid pickling, sulfuric acid pickling, nitric acid pickling corrosion experiments of multifunctional pickling corrosion inhibitor developed by our company were carried out. The experimental results show that the multifunctional pickling corrosion inhibitor in hydrochloric acid pickling, sulfuric acid, nitric acid pickling process has very good inhibition effect for carbon steel and16 mn steel; different drug concentration has different corrosion inhibition effect. Multifunctional pickling corrosion inhibitor concentration commonly is 3‰~5‰, 10% hydrochloric acid pickling corrosion inhibition rate can reach 98.8%, 10% sulfuric acid pickling corrosion inhibition rate can reach 99.8%, 10% nitric acid pickling corrosion inhibition rate can reach 77%.
