1、除油的标准添加量为1-2L/100m2；
1. Standard adding amount of Deoiling agent is 1-2L/100m2;
2、当铜含量高于2g/L或每升工作液处理8-10mP2P 板时，请更新槽液；
2. When copper content is higher than 2g/L or 1L working solution processing 8-10mP2P board, please replace solution;
3、当槽液混浊，有大量沉淀时，请更新槽液；
3. When solution is turbid and has plenty deposit, please replace solution;
4、当小孔、残渣或显影效果不好时，可提高除油剂浓度至10%。
4. In case of small hole, residue or bad developing effect, improve concentration of Deoiling agent to 10%;

五、分析方法
V Analysis Method
槽液酸当量分析
Analysis of acid equivalent of solution
1、取2mL稀释液加入250mL锥形瓶中，再加纯水50mL；
1. Take 2ml dilute solution into a 250ml conical flask, and then add 50ml pure water;
2、加3-5滴甲基红指示剂；
2. Add 3-5 drops of methyl red indicator;
3、用0.1N NaoH滴定，滴至溶液由红色变为黄色为终点。
3. Use 0.1N NaoH for titration till the solution turns from red to yellow;
计 算：酸当量（N）=0.1 × V0.1N NaoH（ml）÷2
Calculation: acid equivalent (N) = 0.1 × V0.1N NaoH（ml）÷2
