本文论述以865无机光亮剂的低氰光亮镀锌新工艺。在低氰镀锌液中加入微量的865无机光亮剂(0.1～0.35克/升),可提高镀锌层的抗蚀性,防止锌层生白锈,减小镀层的脆性,使镀层结晶细致光亮,具有美丽的外观。其镀液具有较高的电流效率、均镀能力、深镀能力和极化性能。它克服了长期使用无机光亮剂硫化钠沉淀多、脆性较大和有机光亮剂易分解、脆性大、不易分析的缺点。而且含有865无机光亮剂镀锌液分析简单,易于控制。是今后碱性镀锌无机光亮剂又一个发展的方向。
This article discusses the 865 inorganic brightener low cyanide bright galvanized new technology. Adding a small amount of 865 inorganic brightener (0.1-0.35 g / L) to the low-cyanide zinc plating solution can improve the corrosion resistance of the zinc coating, prevent the white rust of the zinc coating, reduce the brittleness of the coating and make the coating crystalline and meticulous Bright, with a beautiful appearance. The bath has a high current efficiency, are plating capacity, deep plating capacity and polarization performance. It overcomes the shortcomings of long-term use of inorganic brightener sodium sulfide precipitation, brittleness and organic brightener easy decomposition, large brittleness, not easy to analyze. And contains 865 inorganic brightener zinc plating solution analysis is simple and easy to control. Is the future of alkaline zinc plating brightener another direction of development.
