彩涂卷出现爆漆现象的原因
彩涂卷,一种有着很多优良性能的材料,但也会出问题的,发生爆漆的现象,那是什么原因造成的呢?下面跟着小编一起去了解一下吧!
一、配槽时先加钝化液,后加水。由于钝化液的密度问题,比如钝化液的密度高于水的时候会造成原料混合不均匀,会出现钝化层与基板附着力不好,非常容易使彩涂卷的表面出现爆漆的现象。
二、还有钝化板温生产工艺规定是2小时检查一次,原因就是工作人员在检查的时候没有定时的对钝化板温进行跟踪。尤其是冬天的时候,2小时内温度变化也比较大,最终会造成彩涂卷时效,在压型的时候会发生划伤掉漆的现象。
三、在彩涂卷生产的过程中,出口检查镜上有灰尘,还有部分辊子上也有灰尘,灰尘会直接影响到彩涂卷的表面质量,或许刚开始的时候表现不出来,但是一旦时间长了,或者在阳光的暴晒下就会出现爆漆的现象。
