【摘要】：正0故障起因2016年9月,车间领料员错将硝酸领到氯化钾挂镀锌线调节pH值的堆放点。班组工艺管理员用盐酸调节pH值时未仔细看标贴,错将硝酸当作盐酸加入槽中。由于是8 000L的大槽,所以加入硝酸后并未出现明显的故障,只是镀件上出现少量黑色阴影,当时并没有引起重视。我们是三班制生产,白班人员没发觉,夜班人员也没发现,仍将硝酸当作
[Abstract]:In September 2016, the workshop collars mistakenly led nitric acid to the stacking point where the pH value was adjusted by the potassium chloride galvanizing line. When adjusting pH value with hydrochloric acid, the process manager of the team did not carefully look at the label and mistook nitric acid as hydrochloric acid to be added to the tank. Because it is a large trough of 8 000 L, there is no obvious fault after adding nitric acid, only a small amount of black shadow appears on the plating, which did not attract much attention at that time. We are three shifts production, the day shift personnel did not notice, the night shift staff did not notice, still regards the nitric acid as the nitric acid
