| 摘 要： | 研究了铝合金装饰板和铝型材表面喷涂聚偏二氟乙烯涂料的工艺流程,探讨了铝合金的前处理、磷酸-铬酸盐转化膜和聚偏二氟乙烯底漆与面漆之间的配套性,通过在磷酸-铬酸溶液中添加硝酸镍来改善转化膜性能.对铝合金的磷酸-铬酸盐转化膜配方及工艺进行了筛选,得出了加硝酸镍的铝合金磷酸-铬酸盐转化膜的最佳工艺配方.转化膜的抗蚀性是未加硝酸镍的2倍.还研究了铝合金表面喷涂聚偏二氟乙烯涂料的涂装配套性,得到了在铝合金表面喷涂氟碳涂料的最佳配套体系.

| Abstract: | The spraying coating technology of PVDF on aluminium alloy was studied.The specification of phosphate-chromate conversion film was investigated.The composition of phosphating-chromating bath was optimized by means of orthogonal and single factors tests.Nickel nitrate in the solution were used to improve the conversion film properties,such as the corrosion resistance of the film was nearly doubled.The optimum compatibile system of phosphate-chromate conversion film with PVDF primer and PVDF top coating is ob... |
