H_2O_2/H_2SO_4法溶解不锈钢铜包套的新方法

A New Method of Chemical Dissolving Copper Clad on Stainless Steel

介绍了一种用 H2 O2 /H2 SO4溶解不锈钢铜包套的新方法 ,对温度、稳定剂以及各种原料的浓度等影响因素进行了讨论。传统方法大多以硝酸为主要成分 ,在溶解过程中放出有毒的NOX,严重污染环境。本方法无此弊端 。

A new solution to dissolving copper clad on stainless steel is introduced in which comprises hydrogen peroxide,sulfuric acid,etc.The influential factors such as temperature,stabilizer,concentration of raw material are discussed.In conventional dissolving solution,nitric acid is used as the main component which lead to the generation of toxic NO x gases.Instead this method overcomes this shortcoming,so it is significant in protecting environment against pollution.
