| 摘 要： | 通过硫酸与缓蚀剂(GR-912)和苯骈三氮唑(BTA)在不同配比的情况下,分别对金属铁和铜进行腐蚀与缓蚀试验,得出了最优化配方:硫酸清洗剂对铁材质设备清洗时,硫酸的适宜浓度为1mol/L,缓蚀剂GB最佳配比为2∶1,加入量为2‰左右;对铜材质设备清洗时,硫酸的适宜浓度为0.5mol/L,缓蚀剂GB最佳配比1∶2,加入量在1‰左右。该硫酸清洗剂具有高效防腐、超强抑雾、安全廉价、性能稳定、操作方便等优点,为化学清洗工作者和设备管理者提供一种可靠的配方参考。

| Abstract: | Through sulfuric acid and corrosion inhibitor GR-912 and BTA ratio in different cases, iron and copper metal corrosion and corrosion inhibition tests carried out respectively, the optimum formulation was achieved： sulfuric acid pickling agent for cleaning iron equipment, the appropriate concentration of sulfuric acid was lmol/L, the corrosion inhibitor GB best ratio was 2 ： 1, addition amount of around 2 ; cleaning e- quipment for copper material, the appropriate concentration of sulfuric acid was 0. 5tool/L, the corrosion inhibitor GB best ratio was 1 ： 2, addition amount of around 1. The sulfuric acid cleaning agent has many advantages, such as high-efficient anticorrosion, super fog inhibitor, safe and cheap, stable performance, convenient operation, and so on, for chemical cleaning and equipment managers to provide a reliable refer- ence formula. |
