Cov txheej txheej electrophoretic tuaj yeem muab faib ua ntau pawg raws li hom zaj duab xis- tsim cov resin, electrode polarity, thiab cov yam ntxwv ntawm kev ua tau zoo. Cov khoom sib txawv muaj cov yam ntxwv tshwj xeeb ntawm cov khoom siv hauv qab, kev tiv thaiv tsom, thiab txheej txheem txheej txheem, ua tau raws li kev xav tau ntawm ntau hom txheej txheej. Kev nkag siab txog cov pawg no pab xaiv cov txheej txheem tsim nyog raws li cov khoom siv ua haujlwm thiab cov kev xav tau ib puag ncig hauv kev tsim khoom tiag tiag kom ua tiav cov txheej txheem zoo tagnrho thiab kev pabcuam lub neej.
Raws li electrode polarity, ntau hom yog anodic electrophoretic txheej thiab cathodic electrophoretic txheej. Nyob rau hauv anodic electrophoretic txheej, cov resin hais tsis zoo nqi nyob rau hauv da dej. Thaum lub sij hawm txheej, lub workpiece ua raws li lub anode, thiab cov txheej txheem migrate mus thiab tso rau ntawm workpiece nto. Hom kab ke no tau siv dav hauv yav dhau los vim nws tus nqi qis, tab sis nws tsis zoo rau cathodic electrophoresis raws li kev tiv thaiv corrosion thiab feem ntau yog siv rau kev tiv thaiv dav dav lossis cov khoom siv sab hauv tsev. Nyob rau hauv cathodic electrophoretic txheej, cov resin hais yog zoo them, thiab lub workpiece ua raws li cathode. Nyob rau hauv lub zog ntawm ib qho hluav taws xob teb, cov khoom yog tso rau ntawm qhov chaw. Vim tias cov tshuaj tiv thaiv cathodic txo cov kev xav ntawm corrosion ntawm cov hlau substrate, thiab cov resin nws tus kheej muaj tus ntoo khaub lig siab -kev sib txuas ceev, cov yeeb yaj kiab uas tau tshwm sim ua rau muaj kev tiv thaiv zoo rau cov tshuaj tsuag ntsev thiab tshuaj lom neeg, ua rau nws qhov kev xaiv zoo tshaj plaws rau thaj chaw uas muaj cov kev xav tau zoo xws li tsheb thiab cov khoom siv hauv tsev. Raws li cov txheej txheem resin, cov txheej txheej electrophoretic feem ntau yog muab faib ua epoxy electrophoretic txheej, acrylic electrophoretic txheej, thiab polyurethane- hloov kho electrophoretic txheej. Epoxy electrophoretic coatings siv epoxy resin ua cov matrix, uas ua rau ib tug tawv thiab ntom zaj duab xis tom qab ntoo khaub lig{10}}txuas. Lawv muaj cov tshuaj lom neeg zoo thiab dej tsis kam thiab feem ntau yog siv rau cov khoom siv thiab cov khoom siv tsheb uas muaj kev tiv thaiv corrosion siab. Acrylic electrophoretic coatings muab cov xim vibrant, huab cua zoo heev, thiab tsis tshua muaj xim daj thaum siv sab nraum zoov, ua rau lawv tsim nyog rau cov khoom siv kho kom zoo nkauj uas xav tau cov tsos zoo thiab UV tsis kam. Polyurethane-hloov electrophoretic coatings muab cov tawv tawv ntawm epoxy nrog cov huab cua tsis kam ntawm acrylic, muab kev sib npaug ntawm kev ua haujlwm tsis zoo, khawb tsis kam, thiab zoo li khaws cia, ua rau lawv haum rau siab -kawg cov khoom siv thiab cov khoom ua si.
Raws li cov yam ntxwv ua haujlwm, lawv tuaj yeem muab faib ua hom kev tiv thaiv dav dav thiab kev ua haujlwm sib xyaw ua haujlwm. Hom kev tiv thaiv dav dav tsom rau kev tiv thaiv xeb thiab kho kom zoo nkauj, nrog cov qauv yooj yim haum rau siab - ntim, nqi- cov kab ntau lawm. Cov khoom sib xyaw ua ke qhia tshwj xeeb ntxiv lossis cov khoom ntxiv ntxiv rau kev tiv thaiv yooj yim, muab cov haujlwm xws li pob zeb nti tsis kam, siab -kub tsis kam, tus kheej- ntxuav, lossis ua kom tau raws li cov kev xav tau tshwj xeeb ntawm cov tsheb tshwj xeeb, cov khoom siv hluav taws xob, lossis cov khoom siv hauv tsev. Piv txwv li, cov tshuab suav nrog flake-zoo li xeb-inhibiting pigments tuaj yeem txhim kho kev tiv thaiv, thaum lub tshuab nrog cov khoom siv hluav taws xob tuaj yeem siv rau hauv daim ntawv thov electromagnetic shielding.
Tsis tas li ntawd, raws li txoj kev kho, cov txheej txheem electrophoretic tuaj yeem muab faib ua chav tsev -kub tus kheej - ziab thiab ci - hom curing. Feem ntau cov txheej txheem electrophoretic yuav tsum tau ci ntawm qhov kub thiab txias kom tso cai rau cov resin hla tag nrho -txuas, ua tiav cov khoom ruaj khov thiab tiv thaiv kev tshaj tawm. Chav-kub tus kheej- cov txheej ziab ziab cia siab rau cov tshuaj tiv thaiv ntawm cov resin nws tus kheej los yog cov khoom siv ntxiv los ua ib zaj duab xis ntawm chav tsev kub, haum rau cov substrates tsis haum rau siab -kev kho kub lossis rau hauv - kho qhov chaw.
Zuag qhia tag nrho, electrophoretic txheej yog ntau haiv neeg, nrog rau kev sib txawv ntawm polarity, resin, muaj nuj nqi, thiab kho txoj kev. Cov pawg sib txawv hais txog qhov sib txawv ntawm cov txheej txheem qhov rai, cov khoom siv sib txuam, thiab kev ua haujlwm kawg. Kev xaiv tsim nyog tuaj yeem ua kom zoo dua cov nqi thiab kev ua haujlwm zoo thaum ua kom zoo, tso cai rau electrophoretic txheej tshuab txuas ntxiv ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw.
