摘要
采用曼尼希碱缓蚀剂增加了电化学阻抗谱等效电路中的膜电阻和电荷转移电阻。曼尼希碱季铵盐缓蚀剂不仅降低了腐蚀反应动力学方程中的指前因子,而且增加了腐蚀反应的活化能,从而减缓了腐蚀速率。分析曼尼希碱缓蚀剂缓蚀机理及其缓蚀效果影响因素。
Using mannich alkali corrosion inhibitors increase the membrane resistance chemical impedance spectroscopy equivalent circuit and the charge transfer resistance. in the electro- Mannich base quaternary ammonium salt corrosion inhibitor not only reduces the corrosion reaction kinetics equation of refers to the former factor and increases the corrosion reaction activation energy, which slows down the corrosion rate. This paper analyzes the mannich alkali corrosion inhibitor corrosion mechanism and corrosion effect factors.
