過(guò)硫酸銨工藝
Production process of ammonium persulfate
過(guò)硫酸銨是由硫酸銨和稀硫酸電解后結(jié)晶而得。
Ammonium persulfate is crystallized from ammonium sulfate and dilute sulfuric acid after electrolysis.
電解法由硫酸銨和硫酸配制成電解液，經(jīng)除雜質(zhì)后進(jìn)行電解，硫酸氫根在陽(yáng)極放電而生成過(guò)二硫酸，再與硫酸銨反應(yīng)生成過(guò)硫酸銨，干燥制得過(guò)硫酸銨成品
Electrolysis method is to prepare electrolyte from ammonium sulfate and sulfuric acid. After impurities are removed, electrolysis is carried out. Hydrogen sulfate is discharged at the anode to generate persulfuric acid, and then reacts with ammonium sulfate to generate ammonium persulfate, which is dried to produce finished ammonium persulfate
３．過(guò)硫酸銨主要用途
3. Main uses of ammonium persulfate
Ａ．檢定和測(cè)定錳，用作氧化劑。
A. The determination of manganese as an oxidant.
Ｂ．造紙．油脂、肥皂業(yè)用作漂白劑
B. Paper making. Oil and soap industry used as bleach
Ｃ．用作醋酸乙烯、丙烯酸酯、氯乙烯等產(chǎn)品乳液聚合的引發(fā)劑，便宜，所得乳液耐水性較好。同時(shí)也是苯乙烯，丙烯，丁二烯等乳體發(fā)生共聚作用的引發(fā)劑。
C. As an initiator for lotion polymerization of vinyl acetate, acrylate, vinyl chloride and other products, the price is cheap, and the obtained lotion has good water resistance. It is also an initiator for copolymerization of styrene, propylene, butadiene and other emulsions.
Ｄ．化學(xué)工業(yè)用作制造過(guò)硫酸鹽和雙氧水的原料，有機(jī)高分子聚合時(shí)的助聚劑
D. The chemical industry is used as the raw material for the production of persulfate and hydrogen peroxide, and as the polymerization aid for organic polymer polymerization
Ｅ．金屬表面的處理（例如在半導(dǎo)體制造業(yè)：印刷電路的清洗和蝕刻），銅和鋁表面的活化。
E. Treatment of metal surfaces (e.g. in semiconductor manufacturing: cleaning and etching of printed circuits), activation of copper and aluminum surfaces.
Ｆ．在造紙行業(yè)特別是在制漿用作低溫漂白
F. Used for low temperature bleaching in paper industry, especially in pulping
４．存儲(chǔ)條件
4. Storage conditions
儲(chǔ)存于陰涼、干燥、通風(fēng)良好的庫(kù)房。遠(yuǎn)離火種、熱源。包裝密封，防止受潮。應(yīng)與還原劑、活性金屬粉末等分開(kāi)存放，切忌混儲(chǔ)。儲(chǔ)區(qū)應(yīng)備有合適的材料收容泄漏物。
Store in a cool, dry and well ventilated warehouse. Keep away from kindling and heat source. The package shall be sealed to prevent moisture. It shall be stored separately from reductant, active metal powder, etc., and shall not be mixed. The storage area shall be equipped with appropriate materials to contain the leakage.
