针对现有常温发黑工艺中使用的亚硒酸或二氧化硒具有毒性大、价格高的缺点，提出了以硫代 替硒与铜离子反应作为主成膜物质确立的无硒常温发黑体系是解决问题的有效方式之一，并对 该发黑体系的主成膜剂及其它添加剂的选择方向进行了可行性探讨 In view of the toxicity and high price of selenious acid or selenium dioxide used in the existing blackening process at room temperature, a non-selenium-containing black system at normal temperature which is established by the reaction of sulfur with copper ion as the main film forming material is proposed One of the effective ways to solve the problem, and made a feasibility study on the selection direction of the main filming agent and other additives of the blackening system
