本文简述了铜及铜合金光亮酸洗发展的几个过程,提出了无黄烟无污染环境的新工艺。研究开发了新的光亮添加剂应用,不但解决了酸洗过程产生黄烟的问题。同时配合钝化研制了无铬钝化浓缩液。获得了较好的产品质量,同时也能保持较长时间不变色。 In this paper, the process of bright acid pickling of copper and copper alloy is briefly described, and a new technology of non-yellow smoke pollution-free environment is put forward. Research and development of new applications of bright additives, not only solved the pickling process of the issue of yellow smoke. At the same time with the passivation developed chromium-free passivation concentrate. Get better product quality, but also to maintain a long time does not change color.
