采用失重法及动态恒电位极化法研究了自制N—(辛基)顺丁烯酰胺酸(NOSAA)的缓蚀性能。实验结果表明:当在模拟冷却水中含有10~(-2)mol/L的NOSAA时,对45~#钢有极好的缓蚀作用。并研究了该缓蚀剂与钼酸盐的协同缓蚀效应。
The corrosion inhibition of self-made N- (octyl) maleic acid (NOSAA) was investigated by weight loss method and dynamic potentiostatic polarization. The experimental results show that: when simulated cooling water containing 10 -2 mol / L of NOSAA, 45 ~ # steel has excellent corrosion inhibition. The synergistic corrosion inhibition effect between the corrosion inhibitor and molybdate was also studied.
