1.Dab tsi yog qhov cuam tshuam ntawm chromium-muaj cov tshuaj passivation?
Cov resin xaiv adsorbs chromate ions, thiab tom qab elution, nws yog concentrated los ntawm evaporation kom tau ib tug siab -purity chromic acid kua.
Nws tuaj yeem rov qab siv ncaj qha rau hauv lub tank passivation, uas ua kom cov peev txheej siv tau zoo tshaj plaws.
2.Chromium -cov tshuaj dawb passivation zoo li cas?
Rov qab osmosis thiab lwm cov txheej txheem membrane yog siv los mloog zoo rau cov khoom siv dej tshiab.
Nws decomposes organic Cheebtsam, txo COD, thiab ua rau cov dej khib nyiab raws li cov qauv.
Cov txiaj ntsig thiab qhov chaw: Cov kev xav tau ntxiv thiab rov siv dua, ua tiav lub voj voog kaw - voj voog.
Cov dej kho tau raws li cov qauv tso tawm.
3.Dab tsi yog cov ntsiab lus tseem ceeb rau kev siv?
Kev txheeb xyuas tseeb ntawm cov dej khib nyiab: Qhov no yog lub hauv paus ntawm txhua qhov kev txiav txim siab. Kev tsom xam meej yog qhov tseem ceeb los txiav txim siab tag nrho cov chromium, hexavalent chromium, pH, COD, conductivity, thiab cov concentration ntawm cov hlau ions loj.
Txhim kho pretreatment: Txawm li cas los xij ntawm cov txheej txheem xaiv, kev tshem tawm cov roj zoo thiab ntau-stage precision filtration yog qhov yuav tsum tau ua ua ntej rau kev ua tiav, tiv thaiv cov cuab yeej tseem ceeb tom ntej.
Pilot- ntsuas qhov ntsuas: Tom qab txiav txim siab txoj hauv kev, nws yog ib qho tseem ceeb uas yuav tsum tau kom cov khoom siv los yog lub tuam txhab engineering ua qhov kev sim ntawm - qhov chaw sim. Khiav qhov kev sim ntawm cov dej khib nyiab tiag tiag rau ib lub sijhawm los xyuas qhov kev kho mob zoo, cov khoom lag luam zoo, thiab cov nqi khiav lag luam.
Ntsuam xyuas tag nrho cov nqi ntawm lub neej: Sib piv cov cuab yeej siv peev, kev siv hluav taws xob siv hluav taws xob, kev siv reagent, tus nqi ntawm cov khoom lag luam, txuag cov nqi pov tseg pov tseg, thiab cov txiaj ntsig rov qab siv dua, tsis yog thawj zaug peev.
4.Kuv tuaj yeem tau txais kev txhawb nqa kev tshaj lij li cas?
Cov kws tshaj lij kev lag luam kev kho dej khib nyiab engineering tuam txhab lag luam: Lawv tuaj yeem muab cov kev pabcuam ua tiav suav nrog "cov txheej txheem thev naus laus zis + kev tsim qauv engineering + khoom siv + kev teeb tsa thiab commissioning".
Reputable ib puag ncig khoom manufacturers: Tshwj xeeb tshaj yog cov specializing nyob rau hauv daim nyias nyias nyias los yog ion pauv technologies.
Pab pawg thev naus laus zis ib puag ncig los ntawm cov tsev kawm qib siab lossis cov koom haum tshawb fawb: Lawv tuaj yeem muaj cov thev naus laus zis tshiab tshiab thiab tuaj yeem pab thawj tus tsav tsheb- ntsuas ntsuas.
5.Yuav ua li cas kho chromium-muaj cov tshuaj passivation?
Rau kev kho chromium-muaj cov kev daws teeb meem passivation, ion pauv yog txoj hauv kev zoo rau kev ua kom tau txais txiaj ntsig zoo ntawm chromic acid. Yog tias tsis muaj qhov xav tau rov qab siv dua, txo - cov peev txheej rov qab los tsim cov tshuaj chromium tanning yog qhov kev xaiv pheej yig thiab siv tau. Rau chromium- cov kev daws teeb meem dawb passivation, membrane concentration yog qhov tseem ceeb rau kev ua tiav nyob ze - xoom emissions. Txawm hais tias xaiv txoj kev twg los xij, kev txheeb xyuas cov kua dej pov tseg kom raug yog qhov tseem ceeb, ua raws li kev sim- ntsuas qhov ua tau zoo.
