1.产品简介
I. Product Introduction
SBT-204 是PTH活化历程前维护SBT-205 槽液的酸性和比重的预浸液，并确保孔壁被匀称潮湿，避免无害杂质带入SBT-205中；也用于SBT-205槽液的制备。
SBT-204 is the presoak agent which maintains the acid and specific gravity of tank liquor SBT-205 before the activation process of PTH It can ensure an evenly moist pore wall to avoid detrimental impurity brought into SBT-205. Also, it can be used in the preparation of tank liquor SBT-205.

五、槽液维护
V.Maintenance of Solution
依据处置量补加
1. Add as per handling capacity
每处置1000ft2板应补参加1.5-2.5Kg SBT-204 和200-400ml 37% 的HCl于槽中。
Add additional 1.5-2.5Kg SBT-204 and 200-400ml 37%HCI in tank so as to handle each 1000ft2 plate.
依据剖析后果控制
2. Control according to the analysis results
每进步0.1N 酸浓度，每升槽液添7.93ml 37%的HCl 。
Add 7.93ml 37% HCl per liter tank solution as each increase of 0.1N acid concentration.
每进步0.1N 氯化物浓度，每升槽液添5.28 克的SBT-204 。
Add 5.28g SBT-204 per liter tank solution as each increase of 0.1N chloride concentration
依据比重补加

六、剖析办法
VI. Analysis Methods
(一).当量浓度
(I) Equivalent concentration
步调
1. Steps
取样5mL, 加DI水浓缩至100mL
(1) Get 5mL sample and add de-ionized water to 100mL.
(2)加10滴PP 指示剂
(2) Add 10 drop PP indicator
(3)以0.1N NaOH 尺度液滴定至粉白色
(3) 0.1N NaOH standard solution is titrated to pink
盘算
2. Calculation
例：N = N of NaOH x mL of NaOH / 5
Example: 0.12N =0.1 N of NaOH x 6.0 mL of NaOH / 5
强度(%) = N * 830
3. Strength (%) = N * 830
剖析补加公式
4. Analysis of additional formula
补加物料204(L) : (尺度值—剖析值)×槽积×1.63
Additional material 204 (L): (standard value- analysis value) × tank volume×1.63
铜含量
(II) Cu content
步调
1. Steps
取样25mL,加DI水浓缩至100mL
(1) Get 25mL sample and add deionized water to dilute to 100mL
加25mLpH 10缓冲液
(2) Add 25mL buffer solution of PH value10
加5滴PAN指示剂
(3) Add 5 drops PAN indicator
以0.1M EDTA-2Na 尺度液滴定至黄色
(4) 0.1M EDTA-2Na standard solution is titrated to yellow
盘算
2. Calculation
Cu (g/L) = M of EDTA× mL. of EDTA×63.54÷25
例 :
Example:
1.27(g/L) = 0.05M of EDTA×10mL of EDTA×63.54÷25
三、 添加办法
III. Additional methods
每处置50BSM ，增补204 1.1Kg HCL 100mL
Add 1.1Kg 204 and 100mL of HCL as per treatment of each50BSM. |
