设计了由邻氧乙酸苯甲醛-4-吡啶甲酰腙席夫碱80 mg/L,邻香草醛脱氢枞胺席夫碱6 mg/L, ZnSO450 mg/L, Tween-80100 mg/L四元复配缓蚀剂,通过失重法、极化曲线法和电化学交流阻抗技术,研究了该复配缓蚀剂在模拟现实使用环境中的缓蚀性能。结果表明,该复配缓蚀剂的缓蚀率受海水盐度的影响不大,但该复配缓蚀剂的缓蚀性能受海水温度和海水流速的影响较大,当温度低于50℃和流速较低、缓蚀剂浓度为临界浓度时,缓蚀剂对碳钢有很好的抑制作用,而有锈试样和间浸实验发现高浓度的复配缓蚀剂可以抑制碳钢的腐蚀。

The quaternary compound corrosion inhibitor containing neighbouring oxygen ethanoic acid benzene formaldehyde-4-pyridine formyl hydrazone schiff base (80 mg/L), adjacent dehydroabietic vanilla aldehyde amine schiff base (6 mg/L), ZnSO4 (50 mg/L, ) and Tween-80, (100 mg/L) , were studied using weight loss method, polarization curves, AC impedance in a series of simulated actual used environments, The results showed that the inhibitive efficiency of the compound corrosion inhibitor was only slightly affected by salinity, but significantly affected by ocean temperature and flow rate. The corrosion inhibitor had good inhibition effect on carbon steel when the temperature was lower than 50℃, the flow rate was low and the corrosion inhibitor concentration was at a critical concentration. The high concentrations of compound corrosion inhibitor could inhibit the corrosion of carbon steel in rust sample and leaching experiments.
