Electroplating Kev Kho Mob Nkhaus Hlau Washetater Kev Kho Mob

Cov txheej txheem electroplating yog cov txheej txheem uas siv cov hau kev electrochemical los kho kom zoo nkauj, tiv thaiv, lossis muab cov khoom siv tshwj xeeb tshiab rau cov hlau thiab cov khoom siv hlau. Txhawm rau kom muaj qhov zoo ntawm cov khoom lag luam electroplated thiab tsim cov tsos hlau nrog lub ntsej muag zoo nkauj rau lub substrate, xws li roj, xeb, yuav tsum muab tshem tawm kom huv si ua ntej plating. Tsis tas li ntawd, cov kev daws teeb meem nyob rau saum npoo yuav tsum tau ntxuav tom qab plating. Raws li qhov tshwm sim, cov loj ntim ntawm cov txheej txheem hluav taws xob yog tsim tawm thaum lub sij hawm hluav taws xob hluav taws xob, tsim nyog kho ob lub electroplating thiab hnyav hlau zam.

Kev Kho Mob Hluav Taws Xob yog cov nyom thiab cuam tshuam nrog kev sib tw ntawm kev kho cov tshuaj tua hluav taws hnyav. Cov kev kho mob yuav tsum xav txog cov dej ua tau zoo thiab ntim, nrog rau cov txheej txheem txheej txheem, cov khoom siv tau ntau lawm, thiab kev siv dej hauv cov txheej txheem hluav taws xob. Electroplating hnyav hlau pov tseg feem ntau muaj kev nyuaj thiab nyuaj-rau-tswj tau muaj pes tsawg leeg. Nws muaj cov kuab paug muaj kuab lom xws li cyanide, acids, hexalis, tooj liab, npib tsib xee, thiab lwm tus. Ntau yam ntawm cov tshuaj no yog cov tshuaj lom tau heev, nrog qee tus neeg carcinogenic, teratogenic, lossis mutagenic, npe txaus ntshai rau tib neeg kev noj qab haus huv.

 

Kev Kho Mob Hluav Taws Xob feem ntau cov phiaj xwm ntau yam dej ntws, thiab cov khoom siv tshuaj ntxuav kom huv, thiab cov khoom siv ua kom tiav, thiab ua haujlwm los ntawm kev ua haujlwm tsis zoo lossis kev tswj hwm. Tsis tas li ntawd, cov dej khib nyiab yuav los ntawm cov nroj tsuag hauv kev siv thaum lub sijhawm kho cov txheej txheem thiab kev ntsuas ua haujlwm. Electroplating Wastewater ua kom muaj zog nyob ib puag ncig hauv ob txoj kev hauv cov khoom me me ntawm cov khoom pov tseg me me ntawm cov khoom siv tsis muaj zog ntawm cov txheej txheem (feem ntau yog los ntawm kev ntxuav cov txheej txheem).

 

Lub hom phiaj ntawm cov hluav taws xob kev kho kom zoo rau kev kho mob thiab cov tshuaj lom thiab kev rov ua dua tshiab lossis hloov cov tshuaj lom rau hauv cov ntaub ntawv tsis muaj tshuaj lom.

Cov xwm txheej tam sim no ntawm electroplating hnyav hlau khib nyiab kho tshuab

Tshuaj Lom Zem Zej Zog Qauv

Neutralism txoj kev:
(1) Yog tias cov dej khib nyiab muaj qhov siab ntev, nws yuav tsum tau nruab nrab ua ntej tawm.
(2) Electroplating wastewater feem ntau muaj cov hlau hnyav. Thaum amphoteric me li zn, pb, thiab al yog tam sim no, qib pH tam sim no tuaj yeem ua rau redissolution. Yog li ntawd, tus pH yuav tsum tau nruj me ntsis kev tswj hwm, thiab stimag prefipitation yuav tsum tau siv.
(3) Muaj qee qhov dej hauv cov dej khib nyiab, xws li harces, thiab cov tshuaj sib luag, tuaj yeem muab tshem tawm cov hlau hnyav thiab yuav tsum tau muab tshem tawm los ntawm pretreatic ua ntej tsis muaj kev cuam tshuam.
(4) Qee qhov lus me me thiab nyuaj rau khom, yog li flocculus yuav tsum tau ntxiv rau kev pab nag lossis daus.

Sulfide nag lossis daus:
Qhov tsis zoo ntawm cov qauv no suav nrog kev tsim ntawm cov sulfide me me los nag lossis daus uas yooj yim tsim. Ib qho ntxiv, seem sulfide hauv dej tuaj yeem hnov ​​mob nrog cov kua qaub los tsim cov roj av roj ntau dua, ua rau muaj kuab paug hauv theem nrab.

Oxidation-Txo Kho Mob

Cov Qauv Ferrite:
Cov qauv no muaj cov txiaj ntsig xws li cov khoom siv yooj yim, kev ua haujlwm tsis tshua muaj, yooj yim ntawm kev ua haujlwm, thiab tsis muaj kuab paug thib ob. Txawm li cas los xij, qhov tsim ntawm ferrites yuav tsum tau cua sov txog li 70 degree, uas siv lub zog tseem ceeb. Cov dej kho kuj muaj cov salinity siab, thiab hom qauv no tsis tuaj yeem siv rau kev siv dej kom muaj Mercury lossis hlau cov nyom.

Txuj Ci Electrolytic:
Kev kho mob electrolytic ntawm chromium-muaj dej khib nyiab tau siv nyob rau hauv Suav teb tau 20 xyoo. Nws muab kev tshem tawm cov tshuaj tsis zoo, tsis muaj kuab paug thib ob, thiab tso cai rau kev rov ua haujlwm ntawm cov hlau hnyav. Kwv yees li 30 hom hlau ions hauv cov dej khib nyiab tuaj yeem raug tshem tawm los ntawm kev siv hluav taws xob. Kev kho mob electrolysis yog lub thev naus laus zis kho mob uas txo qis qis tiam thiab ua rau kev rov qab zoo ntawm tooj liab, nyiaj, thiab cadmium. Txawm li cas los xij, electrolysis yog tus nqi pheej yig. Kev lag luam ua tau zoo yog feem ntau tau txhim kho thaum lub sijhawm pov tseg yog thawj lub siab ua ntej ua rau hluav taws xob hauv electrolysis.
