在工业生产中需要用到各种各样的化学物料,其中过硫酸钠就是代表物料之一,工业品为白色结晶。早期过硫酸钠的应用并不是广泛(过硫酸铵使用更广),而过硫酸钠中不含铵且具有更好的稳定性,所以其使用在后期逐渐取代过硫酸铵!过硫酸钠在工业生产中的应用主要包括什么?氢氧化钾厂家为您解说。
A variety of chemical materials are needed in industrial production, among which sodium persulfate is one of the representative materials, and industrial products are white crystals. In the early stage, sodium persulfate was not widely used (ammonium persulfate was more widely used), but sodium persulfate did not contain ammonium and had better stability, so its use gradually replaced ammonium persulfate in the later stage! What are the main applications of sodium persulfate in industrial production? Potassium hydroxide manufacturer will explain for you.
1、受污染的土壤修复、水处理(废水净化)、废气处理、有害物质氧化降解;
1. Contaminated soil remediation, water treatment (wastewater purification), waste gas treatment, and oxidative degradation of harmful substances;
2、乳胶或丙烯酸单体聚合液、醋酸乙烯、氯乙烯等产品的引发剂,同时也是苯乙烯、丙烯腈、丁二烯等胶体发生共聚作用的引发剂;
2. Initiator for emulsion or acrylic monomer polymerization liquid, vinyl acetate, vinyl chloride and other products, and initiator for copolymerization of styrene, acrylonitrile, butadiene and other colloids;
3、金属表面的清洁和酸洗(例如在半导体制造业:印刷电路的清洁和蚀刻),铜和铝表面的活化;
3. Cleaning and pickling of metal surfaces (for example, in semiconductor manufacturing industry: cleaning and etching of printed circuits), activation of copper and aluminum surfaces;
4、脱浆剂和漂白剂,特别为低温漂白;
4. Desizing and bleaching agents, especially low-temperature bleaching;
5、染发剂的基本成分之一,起脱色作用。
5. It is one of the basic components of hair dye and plays a decolorizing role.
此外,过硫酸钠常温下逐渐分解,加热或在乙醇中可迅速分解,分解后放出氧气并生成焦硫酸钠。湿气及铂黑、银、铅、铁、铜、镁、镍、锰等金属离子或它们的合金均可促进分解,高温(200℃左右)急剧分解,放出过氧化氢。
In addition, sodium persulfate gradually decomposes at normal temperature, and can be rapidly decomposed by heating or in ethanol. After decomposition, oxygen is released and sodium pyrosulfate is generated. Moisture, platinum black, silver, lead, iron, copper, magnesium, nickel, manganese and other metal ions or their alloys can promote decomposition, and rapidly decompose at high temperature (about 200 ℃) to release hydrogen peroxide.
