电镀添加剂的保质期及储存

更新时间:2018-2-2 来源:电刷镀 标签:

一、电镀添加剂的保质期

电镀添加剂是有保质期的,对于配比恰当,生产工艺合理的光泽剂,大多数的存放时间可以很长,2~3年也不会有什么问题,但是有些光泽剂由于所用的原材料的原因或成分过于复杂,其存放期会有所缩短,只有一年左右。无论是电镀光泽剂的生产商还是用户,都会很关心这样的问题,因此,需要有一定方法来对光泽剂的存放期做出判断。由于没有合适的老化试验方法,光泽剂的存放试验只能以自然存放时间来验证,关键是取样的方法和验证的方法。对于生产商,每生产一批光泽剂,都要取样三次并瓶装标上日期的批次,存放起来,一年或半年一次对其进行溶解性试验和霍尔槽试验,来评判其合格与否。过了存放期以后,仍无变质情况发生,则这种光泽剂的存放期是可靠的。
