本文介绍了用水玻璃取代三乙醇胺并添加少量的 T L 混合光亮剂的锌酸盐镀液,并从电导率、电流效率、均镀能力、深镀能力等方面对溶液进行研究,将其与一般锌盐和氯化胺—氨三乙酸镀液进行了比较。本文还介绍了用此溶液得到的镀层性能及水玻璃的测定方法。 This paper describes the use of water glass instead of triethanolamine and add a small amount of TL mixed brightener zincate bath, and from the conductivity, current efficiency, average plating capacity, deep plating capacity and other aspects of the solution was studied with the general zinc Salt and ammonium chloride - ammonia triacetic acid bath were compared. This article also describes the coating properties obtained with this solution and the determination of water glass.
