过硫酸铵:用途和操作注意事项

来源:http://www.cqeway.com/ 日期:2024-07-05 发布人: 浏览次数:0

  过硫酸铵的用途和操作注意事项。过硫酸铵是白色结晶或粉末,无气味。干燥纯品过硫酸铵能稳定数月,受潮时逐渐分解放出含臭氧的氧,加热则分解出氧气而成为焦硫酸铵。过硫酸铵易溶于水,水溶液呈酸性,并在室温中逐渐分解,在较高温度时很快分解放出氧气,并生成硫酸氢铵。

  The use and operation precautions of ammonium persulfate. Ammonium persulfate is a white crystalline or powder with no odor. Dry pure ammonium persulfate can stabilize for several months, gradually decomposing and releasing ozone containing oxygen when exposed to moisture, and decomposing into ammonium pyrosulfate when heated. Ammonium persulfate is easily soluble in water, and the aqueous solution is acidic. It gradually decomposes at room temperature and quickly releases oxygen at higher temperatures, generating ammonium bisulfate.20200611115335762.jpg

  过硫酸铵的用途

  The use of ammonium persulfate

  1.检定和测定锰,用作氧化剂。漂白剂。照相还原剂和阻滞剂。电池去极剂。用于可溶性淀粉的制备。

  1. Verify and determine manganese as an oxidant. bleaching agents. Photographic reducing agents and blockers. Battery depolarizer. Used for the preparation of soluble starch.

  2.用作醋酸乙烯、丙烯酸酯等烯类单体乳液聚合的引发剂,便宜,所得乳液耐水性较好。还用作脲醛树脂的固化剂,固化速度快。亦用作淀粉胶黏剂的助氧化剂,与淀粉成分中的蛋白质反应提高粘接性,参考用量为淀粉的0.2%~0.4%。也用作金属铜表面处理剂。

  2. It can be used as the initiator of vinyl acetate, acrylate and other vinyl monomer lotion polymerization. It is cheap and the obtained lotion has good water resistance. It is also used as a curing agent for urea formaldehyde resin, with the fastest curing speed. Also used as a co oxidant in starch adhesives, it reacts with proteins in starch components to improve adhesion, with a reference dosage of 0.2% to 0.4% of starch. Also used as a surface treatment agent for metallic copper.

  3.化学工业用作制造过硫酸盐和双氧水的原料,有机高分子聚合时的助聚剂、氯乙烯单体聚合时的引发剂。油脂、肥皂业用作漂白剂。还用于金属板蚀割时的腐蚀剂及石油工业采油等方面。食品级用作小麦改质剂、啤酒酵母防霉剂。

  3. Used in the chemical industry as raw materials for manufacturing persulfates and hydrogen peroxide, as a polymerization aid for organic polymers and an initiator for vinyl chloride monomer polymerization. Oil and soap are used as bleaching agents in the industry. It is also used as a corrosive agent for metal plate etching and oil production in the petroleum industry. Food grade is used as a wheat modifier and beer yeast antifungal agent.

  过硫酸铵的操作注意事项

  Precautions for the operation of ammonium persulfate

  过硫酸铵应该密闭操作,局部排风。操作人员必须经过专门培训,严格遵守操作规程。建议操作人员佩戴头罩型电动送风过滤式防尘呼吸器,穿聚乙烯防毒服,戴橡胶手套。远离火种、热源,工作场所严禁吸烟。

  Ammonium persulfate should be operated in a closed manner with local ventilation. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear a hood type electric air supply filter dust respirator, polyethylene gas protective clothing, and rubber gloves. Stay away from sparks and heat sources, and smoking is strictly prohibited in the workplace.

  过硫酸铵操作时避免产生粉尘。避免与还原剂、活性金属粉末接触。搬运时要轻装轻卸,防止包装及容器损坏。禁止震动、撞击和摩擦。配备相应品种和数量的消防器材及泄漏应急处理设备。倒空的容器可能残留有害物。

  Avoid generating dust during ammonium persulfate operation. Avoid contact with reducing agents and active metal powders. When handling, it is important to load and unload with care to prevent damage to the packaging and containers. Vibration, impact, and friction are prohibited. Equip corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks. Empty containers may have residual harmful substances.
