化工原料氯化钾电镀中光亮剂的作用及说明

发布日期:2018-01-10 作者:甘肃华扬商贸有限公司 点击:

化钾镀锌工艺中,光亮剂起着增加阴极极化的关键作用。没有光亮剂,沉积的锌镀层粗糙,呈海绵状,无实用价值。钾盐镀锌应用初期,只有少数厂家生产光亮剂。主光亮剂为苄叉丙酮,载体为平平加,效果不很理想。至目前,生产光亮剂的厂家很多,生产原料也有了改变,主光亮剂采用苯亚甲基丙酮及邻氯苯甲醛等。载体采用烷基酚乙烯醚、辛基酚聚乙烯醚及脂肪醇聚乙烯醚等,总的说来光亮剂的水平有所提高。但由于选料和组方不同,品种繁多,良莠不齐。

如何选择优质的光亮剂呢?单从外观和产品说明书不好判断。甘肃华扬商贸有限公司建议采用赫尔槽试验的方法。
