一、产品简介
I Product Introduction
一般市售之片碱(NaOH),大约含有3%之杂质,这杂质和消泡剂所产生之胶凝物(CEL)极易造成槽壁及管路等等之其它问题及污染,亦可能衍生许多困扰,为因应PCB产品之品质要求日益趋严,遂开发CL—505去膜液,其特殊之添加剂能有效加快去膜速度和延长槽液的寿命,增加产能和减少废水量。
NaOH sold in market usually contains about 3% foreign matters, which, with defoamer, may produce CEL and causes pollution and other problems to bath wall and pipeline; as the requirement on quality of PCB turns strict day by day, CL—505 stripping liquid is designed, and its special additive can effectively speed up stripping and prolong the use life of solution as well as increase output and reduce waste water.

四、分析方法
IV Analysis Method
槽液方法:
Operating method:
1、取药液5ml稀释于100ml容量瓶中,
1. Take 5ml solution and dilute it in a 100ml bottle;
2、从容量瓶中取1ml于250ml锥形瓶中,
2. Take 1ml solution from the bottle and place it in a 250ml conical flask;
3、加入100ML纯水和3滴酚酞指示剂,
3. Add 100ml pure water and three drops of Phenolphthalein indicator;
4、用0.1N的HCL标准液滴定到红色消失为终点,记下所消耗的毫升数V,
4. Use 0,1N HCL standard solution for titration till the red color disappears, and record the volume V consumed.
(三)计算: 含量=V×20/100×100%
(III) Calculation: capacity= V×20/100×100%
(四)添加方式计算:
(IV) Calculation of adding method:
(标准值-分析值)×槽积=添加量(L)
(standard value – analyzed value) × bath volume = adding amount (L)
