消除香槟色电泳涂漆铝型材色差的工艺实验

Process Test of Removal the Differences of Colors of the Bronze Color Electrophoretic Coating Aluminium Profiles

生产香摈色电泳涂漆铝型材时容易出现色差缺陷；工艺实验证明，为了获得色泽均匀的香槟色电泳涂漆铝型材，准确控制电解着色槽的工艺时间是关键．熟练控制碱蚀槽、阳极氧化槽、电泳槽和烘干炉的工艺参数，能够避免色差缺陷。

In producing the bronze color electrophoretic coating aluminium profiles the differences of colors can be easily created. The process test showed that to produce the uniformly gloss bronze color electrophoretic coating aluminium profiles, exactly controlling process time of electrolytic coloring bath is key. The differences of colors can be dissolved by controlling process parameters of alkali etching bath, anodization bath, electrophoresis bath and bake furnace.
