1.產品簡介
I. Product Introduction
SBT-204 是PTH活化過程前維護SBT-205 槽液的酸性和比重的預浸液，并確�？妆诒痪鶆驖駶�，防止有害雜質帶入SBT-205中；也用于SBT-205槽液的制備。
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、槽液維護
V.Maintenance of Solution
根據處理量補加
1. Add as per handling capacity
每處理1000ft2板應補加入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.
根據分析結果控制
2. Control according to the analysis results
每提高0.1N 酸濃度，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.
每提高0.1N 氯化物濃度，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
根據比重補加

六、分析方法
VI. Analysis Methods
(一).當量濃度
(I) Equivalent concentration
步驟
1. Steps
取樣5mL, 加DI水稀釋至100mL
(1) Get 5mL sample and add de-ionized water to 100mL.
(2)加10滴PP 指示劑
(2) Add 10 drop PP indicator
(3)以0.1N NaOH 標準液滴定至粉紅色
(3) 0.1N NaOH standard solution is titrated to pink
計算
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
強度(%) = N * 830
3. Strength (%) = N * 830
分析補加公式
4. Analysis of additional formula
補加物料204(L) : (標準值—分析值)×槽積×1.63
Additional material 204 (L): (standard value- analysis value) × tank volume×1.63
銅含量
(II) Cu content
步驟
1. Steps
取樣25mL,加DI水稀釋至100mL
(1) Get 25mL sample and add deionized water to dilute to 100mL
加25mLpH 10緩沖液
(2) Add 25mL buffer solution of PH value10
加5滴PAN指示劑
(3) Add 5 drops PAN indicator
以0.1M EDTA-2Na 標準液滴定至黃色
(4) 0.1M EDTA-2Na standard solution is titrated to yellow
計算
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、 添加方法
III. Additional methods
每處理50BSM ，補充204 1.1Kg HCL 100mL
Add 1.1Kg 204 and 100mL of HCL as per treatment of each50BSM. |
