一、 产品简介
I Product Introduction
AC-70是硫酸型的干净和活化剂，用于线路板消费历程。AC 70含有外表活性剂和去氧化剂，可以无效去除铜外表的油脂和氧化膜。别的它对底材仅有极小的打击(0.5-1 µm/h)。
AC-70 is a sulfuric-acid type cleaner and activator, and is used in the production of circuit board. AC 70 contains surfactant and anti-oxidant and can effectively remove the grease and oxide film on copper surface. Besides, it has slim attack on base material (0.5-1 µm/h).
AC-70不含络合剂，废水容易处置。
AC-70 does not contain complexing agent and sewage is easy to process.

2.2 开缸操纵步调（100升计）
2.2 Operating Steps (100L)
1.在已洗濯的缸中参加50升的去离子水；
1.Add 50L deionized water in the cleaned bath;
2. 一连搅拌下迟缓参加2升硫酸。留意：溶液会热；
2. Slowly add 2L sulfuric acid with continuous mixing; Note: the solution will be hot;
3.一连搅拌下迟缓参加3升AC 70；
3.Slowly add 3L AC-70 with continuous mixing;
4.加去离子水至100升。
4.Add deionized water till 100L
三、槽液维护
III Maintenance of Solution
3.1 药品斲丧量
3.1 Chemical Consumption
只要带出消耗，根据操纵条件和外表多少外形，带出消耗约- 20 - 30 ml/m²。
Only has external loss; according to operating condition and surface geometric shape, the external loss is about - 20 - 30 ml/m²
3.2 维护
3.2 Maintenance
加水补足液位。依化验后果补加硫酸。依消费量补加AC 70：3 - 5 m²/l。
Add water to supplement liquid level; according to testing result, add sulfuric acid, and according to output, add 3 - 5 m²/l AC-70
四、剖析
IV Analysis
操纵步调
Operating Steps
1.用移液管取10 ml镀液到250 ml锥形瓶中；
1.Use a pipette to take 10ml solution and place it in a 250ml conical flask;
2.加50 ml去离子水；
2.Add 50ml deionized water;
3.加5-10滴酚酞指示剂；
3.Add 5-10 drops of Phenolphthalein indicator;
4.用1.0 N氢氧化钠尺度溶液滴定至由无色变红为尽头。
4.Use 0.1N NaOH standard solution for titration till the solution changes from colorless to red;
盘算：滴定命 x 2.75 = ml/l硫酸
Calculation: titration ml x 2.75 = ml/l sulfuric acid
五、宁静防护
V Safety Protection
利用时请佩带眼罩、手套及穿宁静防护衣。若药液失慎溅及皮肤、眼睛时使用少量净水洗濯，严峻者应立刻就医诊治。
When using it, please wear eyeshade, gloves and protective clothes; in case that solution spatters into eye or on skin, immediately flush with plenty of clean water and get medical treatment if necessary.
六、废水处置
VI Sewage Treatment
洗濯水可间接用氢氧化钠或碳酸钠中和。废液应浓缩5倍后中和
The cleaning water can be neutralized by sodium hydroxide or sodium carbonate; the sewage shall be diluted by 5 times and then be neutralized; |
