摘要
以钼酸钠、硫脲、吖啶、六次甲基四胺、硫酸锌、表面活性剂等合成了铝翅片换热器酸洗缓蚀剂,并用腐蚀失重法进行了评价。在8%盐酸介质中,钼酸钠∶硫脲∶吖啶∶六次甲基四胺∶硫酸锌∶表面活性剂=0.6∶1.0∶0.2∶0.8∶0.5∶0.05,40℃时,铝缓蚀率可达97%以上。
The corrosion inhibitors of aluminum were synthesized by sodiun molybdic.sulfocarbamide etc and the corrosion inhibition efficacy were studied using the weight loss method. The corrosion inhibition rate is up to 97% in 8% hydrochloric solution.
