摘　　要：对紫铜色铝型材容易出现的诸多表面缺陷原因、两种防褪色工艺机理与存在缺点进行了分析。结果表明:通过试验与工业化应用实践,采用“二次电解着色法”工艺,既能有效地解决紫铜色铝型材褪色问题,又不会产生紫铜色膜裂、颜色失真等新问题。确定了工艺要点与应用条件,并且对“二次电解着色法”工艺的防褪色机理进行了研究。The reasons for surface defects of copper-colored aluminum profiles,the mechanism of two anti-fading processes and their shortcomings were analyzed.The results show that the process of"secondary electrolytic coloring"can effectively solve the fading problem of copper aluminum profiles,and will not cause new problems such as copper film cracking and color distortion through experiment and industrial application practice.Key points of the process and application conditions were determined,and the mechanisms of the“secondary electrolytic coloring method”was also studied.
