摘　　要：通过动态旋转挂片实验,研究了水处理剂腐植酸钠(HA Na)的缓蚀性能以及与Zn2+和葡萄糖酸钠复配的缓蚀协同效应。结果表明:HA Na对碳钢有一定的缓蚀作用;与Zn2+复配有较好的协同效应,而与葡萄糖酸钠复配没有协同效应;但是,HA Na,Zn2+和葡萄糖酸钠三者复配表现出优异的缓蚀性能。还探讨了HA Na的缓蚀作用机理。The ability of corrosion inhibition and synergistic effect of water treatment agent of sodium humate(HA-Na) with Zn^(2+) and sodium gluconate were studied through dynamic experiments. The results show that HA-Na had good inhibition effect on steel. The synergistic effect between HA-Na and Zn^(2+) was good, but the effect between HA-Na and sodium gluconate was poor. However, the synergistic effect among HA-Na, Zn^(2+) and sodium gluconate was very good. The corrosion inhibition mechanism of HA-Na is discussed.
