Khoom noj khoom haus additives phosphoric acid
Cov lus qhia zoo (GB / T 1886.15-2015)

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

Phosphoric acid feem ntau yog siv rau hauv kev lag luam, zaub mov, chiv thiab lwm yam lag luam, suav nrog cov tshuaj tiv thaiv xeb, khoom noj khoom haus, kho hniav thiab orthopedic phais, EDIC caustics, electrolytes, flux, dispersants, industrial caustics, chiv ua raw cov ntaub ntawv thiab cov khoom siv tu tsev. cov khoom. Kuj tseem siv los ua cov tshuaj siv tshuaj, phosphates yog cov as-ham rau txhua hom kev ua neej.

Phosphoric acid los yog orthophosphoric acid, nrog ib qho hnyav molecular ntawm 97.994, yog ib hom inorganic acid. Nws yog 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.

Daim ntawv thov teb:

1. Kev ua liaj ua teb: Phosphoric acid yog cov khoom siv raw rau kev tsim cov phosphate chiv tseem ceeb (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. Kev lag luam: Phosphoric acid yog ib qho tseem ceeb tshuaj raw khoom. Nws lub luag haujlwm tseem ceeb yog raws li hauv qab no:

(1) Txhawm rau kho cov hlau nto thiab tsim cov phosphate zaj duab xis insoluble ntawm cov hlau nto los tiv thaiv cov hlau los ntawm corrosion.

(2) Sib xyaw nrog nitric acid ua cov tshuaj txhuam hniav txhawm rau txhim kho qhov ua tiav ntawm cov hlau nto.

(3) Kev tsim cov tshuaj ntxuav tes, tshuaj tua kab raw khoom phosphate ester.

(4) Cov khoom siv raw rau kev tsim cov phosphorus-muaj nplaim hluav taws.

3, khoom noj khoom haus: phosphoric acid yog ib qho ntawm cov khoom noj 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.

4, tshuaj: phosphoric acid tuaj yeem siv los ua cov tshuaj phosphate, xws li sodium glycerophosphate, thiab lwm yam.
