摘　　要：为了在镀锌钢板表面获得耐蚀性强、与漆膜附着性好的晶态磷化膜，以硫酸羟胺、间硝基苯磺酸钠、聚乙烯醇等促进剂和添加剂进行正交试验，优选出了一种低温少渣新型磷化液。结果表明：镀锌钢板在该优选磷化液中于28-33℃磷化处理2．5min，可在其表面形成均匀、致密、耐蚀性强的磷化膜，而且膜层各项性能均能达到国家标准。该新型磷化技术有望取代传统的亚硝酸盐磷化。With hydroxylamine sulfate,sodium metanitrobenzene sulfonate,polyvinyl alcohol as promoters and other additives,the orthogonal experiments were carried out to optimize a novel phosphating solution with less dreg in low temperature.Results showed that a uniform phosphating film with excellent corrosion resistance could be formed on galvanized steel surface after phosphating for 2.5 min at 28-33℃ in the optimal phosphating solution.Moreover,the properties of film could meet the national standard.Thus,this novel phosphating technology was expected to replace the traditional nitrite phosphating.
