由于亚硝酸盐潜在的毒性问题。近几年来,国内外纷纷寻找替代亚硝酸盐的水溶性防锈剂。替代物有有机防锈剂和无机防锈剂。有机防锈剂对铸铁的防锈效果不如亚硝酸盐,且必须高浓度使用;无机防锈剂有硼酸盐、磷酸盐、硅酸盐、钼酸盐等。近几年来,有关钼酸盐作为防锈剂的报导较多,在本文中,笔者汇集了国内外钼酸盐防锈效果的有关文献资料,并对此进行了应用试验。一、钼酸盐的防锈效果 Potential toxicity problems due to nitrite. In recent years, at home and abroad have to find alternative water-soluble nitrite rust inhibitor. Alternatives are organic rust inhibitors and inorganic rust inhibitors. Antirust effect of organic rust inhibitor on cast iron as nitrite, and must be used at high concentrations; inorganic rust inhibitors borate, phosphate, silicate, molybdate and so on. In recent years, there are many reports about molybdate as a rust inhibitor. In this paper, the author has collected relevant literature materials about molybdate rust prevention effects both at home and abroad, and applied the experiment. First, the anti-rust effect of molybdate
