配制原油模拟液,研究了二乙基二硫代氨基甲酸钠(SDDTC)于模拟液中单独使用以及分别与硫酸锌,铬酸钠的复配对316L钢的缓蚀效果.实验表明:在高酸高氯环境下,SDDTC能够很好地抑制316L钢的腐蚀;而且SDDTC与硫酸锌、铬酸钠之复配缓蚀剂具有很好的协同增效作用.这一相关研究具有重要的实际应用意义.
The crude oil simulation liquid was prepared to study the corrosion inhibition effect of SDDTC in the simulated liquid alone and in combination with zinc sulfate and sodium chromate on the 316L steel.The experimental results show that in the high acidity high Under the chlorine environment, SDDTC can restrain the corrosion of 316L steel well, and SDDTC has good synergistic effect with zinc sulfate and sodium chromate compound corrosion inhibitor.This research has important practical significance.
