摘　　要：甲基磺酸盐镀锡液是一种环保性好、生产效率高、性能优良的新型镀锡液。采用赫尔槽试验,电化学测试等手段,对镀液的电导率、沉积速率、分散能力、覆盖能力、镀液的极化能力以及镀层性能分析研究,结果表明,该镀液在45℃时的电导率为176 ms/cm,镀液的分散能力和覆盖能力分别为97.8%,82.4%,镀液的极化能力强,得到的镀层结晶细致,添加剂加入后明显改善了镀液的极化性能,提高了锡离子的析出电位。The methyl sulfonic acid tinplate bath is a new type ot electrolyte, and it has some advantages such as high environmal- protection and wide productive scope and good electrolic ability. In this paper , the performance, which consisted of conductance, covering, dispersion and cathodic polarizing abilities and depos- iting velocity,has been studied by Hull cell text and Electrochemistry performance text The results show that electrolyte＇s conductance is 176 ms/cm at 45℃, and covering and dispersion of electrolyte is 97. 8% ＆ 82. 4%. Cathodic polarizing abilities of electrolyte have been improved and crystal potential of Sn^2＋ had increased by append additive.
