摘　　要：铝型材阳极氧化表面处理对环保影响很大,实现表面处理工艺向环保型工艺转换是必然趋势。针对国内众多铝型材企业在Sn-Ni混合盐常用电解着色工艺向环保型Sn盐工艺转换过程中,遇到与原色调存在差异、颜色分布能力较差和条带型分色缺陷明显等问题,根据实验室试验与生产实践经验,分析了问题的根源,并提出了相应的解决办法。The anodizing surface treatment of the Al profile has a great influence on the environment.Transformation to environmentally friendly technology is an inevitable trend. Several problems of the color difference,poor dispersion ability and obvious color separation defect are encountered during Al profile in the course of transformation from Sn-Ni mixed salt to Sn salt in the electrolytic coloring. According to the study results and practical experience,problems are analyzed and corresponding solutions are proposed.
