印花彩涂板酸洗六大注意点

印花彩涂板的应用越来越广泛，但印版是焊后酸洗的。印花彩涂板如果处理不好，很容易造成彩涂钢板生锈。因此，在酸洗过程中要注意以下六点：

1也可用硫酸酸洗，酸洗时间不宜过长；
2用浓度为1~2的草酸进行表面调整；
三。tal控制在15点左右，pH值不超过13；
4 印花彩涂板锌磷化处理的酸度为上限，印花彩涂板浸渍处理浓度：TA:35以上；FA:1.2ac:8（20cc发酵管）；
5酸洗后用1～2碳酸钠中和；
6印刷板必须清洗干净，水冲洗应保持溢出。

The printing plate is more and more widely used, but the printing plate is pickled after welding. If the treatment is not good, it is easy to cause the color coated steel plate to be rusted. Therefore, we should pay attention to the following six points in the pickling process:

1. Sulfuric acid can also be used for pickling, and the pickling time should not be too long;
2. Oxalic aid was used for surface adjustment with concentration of 1 ~ 2;
3. The tal should be controlled at about 15 point and the pH should not exceed 13;
4. The acidity of zinc phosphating treatment should be taken as the upper limit, the concentration of impregnation treatment: TA: 35 or above; FA: 1.2ac: 8 (20cc fermentation tube);
5. After pickling, it was neutralized with 1 ~ 2 sodium carbonate;
6. The printing board must be cleaned, and the water washing should keep overflow.
