采用稳态极化法研究了硫脲等有机胺在硫酸介质中对 4 5# 碳钢的缓蚀作用及与 I-的协同效应 ,并与 Cl-的协同效应进行了对比。结果表明 :硫脲的缓蚀性能最佳 ;几种有机胺与 I-有明显的协同效应 ;乙二胺与 I-复配使用比单独使用时缓蚀效率提高了一倍 ;尿素与 I-为负协同效应。
The steady-state polarization method was used to study the synergistic effect of thiourea and other organic amines on 45 # carbon steel in sulfuric acid medium and the synergistic effect with I-. The results show that thiourea has the best corrosion inhibition performance. Several organic amines have a synergistic effect with I-. The corrosion inhibition efficiency of ethylenediamine and I- Negative synergistic effect.
