Phosphoric acidcov khoom siv cog
1.Process piav qhia ntawmphosphoric acid
Phosphoric acid, tseem hu ua orthophosphoric acid, yog ib hom inorganic acid nrog cov tshuaj formula H.3PO4thiab qhov hnyav molecular ntawm kwv yees li 97.994. Nws yog tribasic nruab nrab-lub zog acid, muaj cov yam ntxwv ntawm acidic, thiab tsis yooj yim volatile, decomposed, los yog oxidized. Phosphoric acid muaj ntau yam kev siv hauv kev ua liaj ua teb, kev lag luam, thiab kev lag luam zaub mov.
Phosphoric acid feem ntau yog tsim los ntawm cov txheej txheem ntub dej lossis cov txheej txheem thermal. Qhov qub yog qhov siv tshuab tshaj plaws rau kev tsim cov phosphoric acid.
Tag nrho cov txheej txheem muaj xws li phosphate pob zeb zom, gypsum sib cais, purification thiab concentration. Cov pob zeb phosphate yog tov nrog sulfuric acid los tsim phosphoric acid thiab gypsum. Tom qab kev zom, gypsum yog cais los ntawm cov tshuaj phosphoric acid. Cov tshuaj phosphoric acid tau dhau los ua cov kauj ruam purification kom tshem tawm impurities. Lub purified phosphoric acid yog concentrated rau lub zog xav tau.
Ib txoj hauv kev purification rau phosphoric acid yog kua-kua extraction, uas muaj kev sib cais ntawm phosphoric acids los ntawm dej thiab lwm yam impurities siv organic solvents, xws li tributyl phosphate (TBP), methyl isobutyl ketone (MIBK), los yog n-octanol. Nanofiltration suav nrog kev siv cov txheej txheem ua ntej hloov pauv nanofiltration membrane, uas yog ua haujlwm los ntawm kev tso nyiaj ntawm lub siab molecular hnyav polycationic polymer ntawm polyethyleneimines. Nanofiltration tau pom tias txo cov concentration ntawm ntau yam impurities, suav nrog cadmium, aluminium, hlau, thiab cov ntsiab lus tsis tshua muaj hauv ntiaj teb.
2.Peb tuaj yeem ua dab tsi hauv qhov project phosphate acid?
CBETC tau tsom mus rau kev lag luam tshuaj phosphorus tau ntev. Raws li peb tus kheej R & D lub zog, peb koom tes nrog cov tsev kawm ntawv qib siab, cov tsev kawm ntawv thiab cov chaw tsim khoom, txhawb kev sib koom ua ke nrog kev xyaum, mob siab rau peb tus kheej rau kev txhim kho thiab siv phosphoric acid technology. Rau ntau hom phosphate pob zeb, los ntawm cov txheej txheem kev ntsuam xyuas, raws li peb cov kev ua tau zoo, peb tuaj yeem tsim cov txheej txheem tsim nyog nrog cov khoom zoo, siab phosphorus rov qab tus nqi, tsawg zog noj, ib puag ncig tus phooj ywg, thiab tsis tshua muaj peev txheej. .
