一、概述镀银层在大气环境中SO_2、H_2S等腐蚀性介质的作用下,很快会使银层表面生成浅黄色、黄褐色、甚至黑褐色的硫化银(其溶度积=1.6×10~(-49))薄膜,它与含硫的橡胶、胶木、油漆等物质接触,或者在高温高
First, an overview of silver-plated layer in the atmospheric environment SO_2, H_2S and other corrosive media under the action of the silver layer will soon be generated on the surface of light yellow, brown, or even dark brown silver sulfide (solubility product = 1.6 × 10 ~ (-49)) film, it with sulfur rubber, bakelite, paint and other substances in contact, or at high temperature and high
