【摘要】 应用阴极极化法、旋转圆盘电极法和赫尔槽试验法研究了香草醛在无氰碱性镀锌中的作用。结果表明 :香草醛能够明显地增大阴极极化 ,并在一定浓度范围内对镀层有“正整平”能力的趋势 ,它对镀液的分散能力是很有利的 ,并显著地增加了镀层的光亮度更多还原

【Abstract】 The functions of vanillin in zinc-plating with noncyanide-alkaline solution were studied with cathodic polarization, rotating disk electrode and Hull Cell testing methods. The experimental results showed that vanillin could raise cathodic polarization obviously and had a good leveling effect within the range of concentration. So it impsored the throwing powder of zinc plating solution and raised the lustre of deposit evidently.更多还原
