The appearance of sodium persulfate is white crystalline powder, which is easily soluble in water and can accelerate decomposition in humidity and high temperature; It can be decomposed by ethanol and silver ions, and the solubility in water is 549g/l at 20 ℃; Sodium persulfate is also prone to deliquescence. In wet air and high temperature, it can accelerate the decomposition of sodium persulfate, release oxygen and become sodium pyrosulfate.
過(guò)硫酸鈉用途主要有哪些
What are the main uses of sodium persulfate
過(guò)硫酸鈉溶液呈酸性反應(yīng)，能被醇和銀離子分解，還能與可燃物或易氧化物發(fā)生燃燒，并能助燃、助長(zhǎng)火勢(shì)，劇烈時(shí)甚發(fā)生爆炸。存放時(shí)會(huì)慢慢分解，過(guò)硫酸鈉溶液在室溫下已有明顯分解，具有強(qiáng)氧化性。
Sodium persulfate solution has an acidic reaction, can be decomposed by alcohol and silver ions, can also burn with combustibles or easy oxides, and can support combustion, contribute to fire, and even explode when it is violent. It will decompose slowly during storage. Sodium persulfate solution has been significantly decomposed at room temperature and has strong oxidation.
那么,過(guò)硫酸鈉用途都有哪些呢？
So, what are the uses of sodium persulfate?
過(guò)硫酸鈉用途主要用作漂白劑、氧化劑、乳液聚合促進(jìn)劑。還可用于照相業(yè)的廢液處理，用作印刷電路板表面金屬的軟蝕劑及紡織用脫漿劑、硫化染料發(fā)色劑等。用作油井壓裂液的破膠劑、電池去極化劑及有機(jī)高分子乳化聚合引發(fā)劑。照相工業(yè)用于膠片顯影、定影劑;還可用作廢液處理劑、金屬表面處理劑、印刷電路版的蝕刻劑等。
Sodium persulfate is mainly used as bleaching agent, oxidant and lotion polymerization promoter. It can also be used for the treatment of waste liquid in the photographic industry, as a soft etchant of metal on the surface of printed circuit boards, as a desizing agent for textiles, a sulfur dye chromogenic agent, etc. It is used as gel breaker of oil well fracturing fluid, battery depolarizer and initiator of organic polymer emulsion polymerization. In the photographic industry, it is used as film developer and fixer; It can also be used as waste liquid treatment agent, metal surface treatment agent, etching agent of printed circuit board, etc.
如存儲(chǔ)不當(dāng)，會(huì)導(dǎo)致過(guò)硫酸鈉用途大大降低，所以過(guò)硫酸鈉應(yīng)儲(chǔ)存于陰涼、干燥、通風(fēng)良好的庫(kù)房。遠(yuǎn)離火種、熱源。庫(kù)房溫度不超過(guò)30℃，相對(duì)濕度不超過(guò)80%。使用完后包裝要密封，要與還原劑、活性金屬粉末、堿類(lèi)、醇類(lèi)等分開(kāi)存放，切忌混儲(chǔ)。
Improper storage will greatly reduce the use of sodium persulfate, so sodium persulfate should be stored in a cool, dry and well ventilated warehouse. Keep away from kindling and heat sources. The temperature in the warehouse shall not exceed 30 ℃, and the relative humidity shall not exceed 80%. After use, the package should be sealed and stored separately from reductants, active metal powders, alkalis, alcohols, etc. do not mix them.
