Siv:
Kev ua liaj ua teb siv: raw khoom ntawm phosphate fertilizer thiab pub cov as-ham
Kev lag luam siv: chemical raw khoom
1. Tiv thaiv cov hlau los ntawm corrosion
2.Mixed nrog nitric acid ua tshuaj polishing tus neeg saib xyuas kom txhim kho qhov chaw tiav ntawm cov hlau
3.Material ntawm phosphatide uas yog siv los tsim cov khoom siv ntxhua khaub ncaws thiab tshuaj tua kab
4.Kev tsim cov phosphorus uas muaj cov ntaub ntawv flameretardant.
Khoom noj khoom haus additives siv: acidic flavoring, Poov Nutri-ents, xws li coca-cola.
Kev siv kho mob: los tsim cov tshuaj uas muaj phos-phorus, xws li Na 2 Glycerophosphat
Lub luag haujlwm tseem ceeb ntawm phosphoric acid:
1. Phosphoric acid yog cov khoom siv raw rau kev tsim cov phosphate chiv tseem ceeb (calcium superphosphate, potassium dihydrogen phosphate, thiab lwm yam), thiab tseem yog cov khoom siv raw rau kev tsim cov khoom noj pub mis (calcium dihydrogen phosphate).
2, kho cov hlau nto, tsim insoluble phosphate zaj duab xis ntawm cov hlau nto, thiaj li tiv thaiv cov hlau los ntawm corrosion.
3, tov nrog nitric acid raws li ib tug tshuaj txhuam hniav, los txhim kho cov tiav ntawm cov hlau nto.
4, kev tsim cov khoom siv ntxhua khaub ncaws, tshuaj tua kab raw khoom phosphate ester.
5, kev tsim cov khoom siv raw uas muaj phosphorus nplaim retardant.
6, phosphoric acid yog ib qho ntawm cov khoom noj khoom haus additives, nyob rau hauv cov zaub mov raws li ib tug qaub neeg sawv cev, poov xab tus neeg saib xyuas, cola muaj phosphoric acid. Phosphates tseem yog cov khoom noj khoom haus tseem ceeb thiab tuaj yeem siv los ua cov khoom noj ntxiv.
7. Phosphoric acid tuaj yeem siv los ua cov tshuaj uas muaj phosphate, xws li sodium glycerophosphate.
Phosphoric acid los yog orthophosphoric acid, tshuaj formula H3PO4, molecular hnyav 97.994, yog ib hom inorganic acid, yog ib tug nruab nrab muaj zog acid. Nws yog tau los ntawm dissolving phosphorus pentoxide nyob rau hauv dej kub. Orthophosphoric acid tau txais kev lag luam los ntawm kev kho apatite nrog sulfuric acid. Phosphoric acid dehydrates yooj yim hauv huab cua. Thaum tshav kub kub poob dej rau pyrophosphoric acid, thiab ntxiv poob dej rau metaphosphate.
