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
Hauv kev lag luam tshuaj, phosphoric acid yog ib yam khoom tseem ceeb heev, tab sis qhov tseeb, phosphoric acid kuj tseem yuav tsum tau nkag siab qhov sib txawv! Piv txwv li, dab tsi yog qhov txawv ntawm qib zaub mov thiab qib phosphoric acid hauv kev siv?
Cov ntsiab lus ntawm cov khoom noj thiab qib phosphoric acid nce mus txog 85% thiab 75%. Kev lag luam qib phosphoric acid feem ntau yog siv rau hauv kev lag luam tshuaj, suav nrog textile printing, ntau lawm ntxuav, ntoo refractories, metallurgy thiab lwm yam hlau industries; Khoom noj khoom haus qib phosphoric acid tuaj yeem siv rau hauv cov khoom noj txhua hnub xws li cov khoom siv mis nyuj, cawv txiv hmab, qab zib thiab roj ua noj.
Dab tsi yog cov kev siv tseem ceeb ntawm cov zaub mov qib phosphoric acid?
1. Nws tuaj yeem siv los ua cov khoom noj ntxiv, xws li citric malic acid thiab lwm cov kua qaub tsw, thiab nws plays nws lub luag hauj lwm ua raw khoom rau poov xab thiab phosphate hauv kev ua noj.
2. Cov neeg nyiam cawv yuav tsum tsis txhob muaj phosphoric acid! Thaum brewing, phosphoric acid tuaj yeem muab cov khoom noj tsis tu ncua rau cov poov xab, uas tiv thaiv kev loj hlob ntawm cov kab mob stray; Hauv cov txheej txheem ntawm kev ua npias, nws tuaj yeem ua lub luag haujlwm zoo ntawm lactic acid los kho tus nqi PH!
3. Cov peev txheej dej tam sim no tseem ceeb heev, thiab phosphoric acid kuj tseem siv tau los ua cov khoom siv raw ntawm cov tshuaj ntxuav nplai thiab cov tshuaj ntxuav dej, muab cov dej ntshiab rau peb.
Muaj qib phosphoric acid yog ib qho nyuaj me ntsis, tab sis nws kuj tau siv ntau dua:
1. Phosphoric acid yuav tsum muaj qhov chaw hauv kev lag luam hlau. Yog tias koj xav ua kom cov hlau nto ntawm kev tsim khoom thiab siv ntau dua thiab zoo nkauj, phosphoric acid yuav tsum yog qhov tseem ceeb. Thaum nyob rau hauv kev sib cuag nrog cov hlau, nws yuav pab tau rau saum npoo ntawm cov dej insoluble phosphate zaj duab xis, txawm nyob rau hauv lub tom ntej ua hauj lwm, kom txo tau cov hlau corrosion.
2. Kev tu lub peev xwm ntawm phosphoric acid yeej tsis quav ntsej los ntawm ntau tus neeg. Hauv kev lag luam luam ntawv, nws tuaj yeem siv rau hauv cov kua ntxuav kom tshem tawm cov stains ntawm lub phaj offset ntau dua, thiab nws tuaj yeem dhau los ua ib feem ntawm cov tshuaj ntxuav tes hauv kev lag luam tshuaj txhua hnub!
3. Tsis tas li ntawd, nws kuj muaj nws qhov chaw hauv kev txhim kho lub neej kev pab cuam ntawm lub cub tawg, roj teeb electrolytes thiab txawm tias nquag siv cov khoom tu tawv nqaij thiab tshuaj pleev ib ce.
