我国铝制品化学抛光工艺开发现状

The Status in Quo of Development in Chemical Polishing Technology for Aluminum Products in China

介绍铝制品传统三酸化学抛光工艺产生氮氧化物气体(NO_x,“黄烟”),对环境造成的污染。综述了80年代以来,我国治理黄烟的现状和研究成果。

This paper provides an introduction to the effects on environment of yellow fume of nitrogen oxides(NOx) in normal chemical polishing process for aluminum products. The progress of yellow fume control in china since 1980 was reviewed. It is pointed out that more efforts should he taken for the development and application of non-yel low fume polishing technology, especially for that of non-nitric acid chemical polishing technology.
