摘要
研究了以亚硫酸盐为主络合剂的无氰镀银工艺.研究中发现加入一种添加剂,可大大提高镀液的稳定性,并使镀层光亮细致.同时,还研究了温度、pH值、添加剂等对镇液性能及镀银层性能的影响.
The electrowinning process of silver with sulphite as the main complexing agent other than with cynide was studied. Using a special additive, the stability of the electrowinning solution was enhanced greatly and the electrowinning layer of Ag was smooth and shiny' The effect on the electrowinning solution and Ag layer of temperature, pH and additive has also been studied.
