Electrophoretic txheej yog txheej txheej thev naus laus zis uas siv lub tshuab hluav taws xob kom ua tiav cov txheej txheem txheej txheej, ua lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub tiv thaiv corrosion thiab kho kom zoo nkauj. Los ntawm kev siv cov hluav taws xob ncaj qha tam sim no, cov khoom sib txawv ntawm cov txheej txheem sib txawv txav mus rau qhov chaw ua haujlwm hauv qab ntawm lub zog hluav taws xob thiab tso rau hauv zaj duab xis. Cov yeeb yaj kiab no yog tom qab ntawd ci thiab kho kom tsim tau ib txheej txuas ntxiv thiab ntom ntom. Vim tias qhov sib txawv ntawm cov hluav taws xob sib txawv, cov txheej txheem tuaj yeem nkag mus rau hauv cov kab noj hniav thiab cov fab, ua tiav cov kev pab cuam uas nyuaj rau kev ua tiav nrog cov tshuaj txau.
Cov yam ntxwv tseem ceeb tshaj plaws ntawm txoj kev txheej txheej no yog kev tswj tau thiab cov yeeb yaj kiab tsis sib xws. Nyob rau hauv lub zog ntawm hluav taws xob teb, tus nqi deposition yog ze ze rau cov xim tsis, voltage, thiab lub sij hawm, yog li ua tiav ib tug ruaj khov thiab zoo ib yam tiv thaiv nyhuv ntawm txawv substrates thiab duab. Electrophoretic films feem ntau muaj cov adhesion zoo, corrosion kuj, thiab txhua yam muaj zog, ua rau lawv tshwj xeeb tshaj yog haum rau cov hlau uas yuav tsum tau muaj huab cua tsis kam thiab tiv thaiv xeb. Piv txwv li, lub cev tsheb, thav duab, thiab cov khoom siv feem ntau siv cathodic electrophoresis los tswj kev ua tau zoo nyob rau lub sijhawm ntev hauv qhov chaw hnyav thiab kev nyab xeeb.
Lwm qhov zoo ntawm electrophoretic txheej yog nyob rau hauv nws qhov sib npaug ntawm kev tiv thaiv ib puag ncig thiab kev ua haujlwm zoo. Cov txheej da dej yog rov ua dua tshiab, ua rau muaj kev siv cov txheej txheem siab thiab tsawg kawg ntawm cov organic solvent emissions, yog li txo cov pa paug pov tseg thiab hluav taws kub. Automated tswj ntawm cov kab ntau lawm tsis tsuas yog shortens lub voj voog txheej, tab sis kuj txo cov kev hloov pauv zoo los ntawm tib neeg kev ua yuam kev. Rau qhov nyuaj- zoo li cov workpieces ua nyob rau hauv loj batch, electrophoretic txheej muaj peev xwm ua tau siab - zoo tiv thaiv ntawm tus nqi qis tag nrho, thiab yog li ntawd dav siv nyob rau hauv teb xws li cov cuab yeej cuab tam, cuab yeej kho vajtse, thiab lub tsev steel lug.
Los ntawm kev xav ntawm zaj duab xis tsim mechanism, cov txheej txheem electrophoretic muaj plaub theem: electrolysis, electrophoresis, electrodeposition, thiab electroosmosis. Electrolysis decomposes cov dej hauv cov tshuaj pleev xim, tsim cov pa roj thiab hloov qhov chaw ntawm lub ntsej muag; electrophoresis txhawb kev taw qhia txav ntawm cov khoom them; electrodeposition tso cai rau cov khoom sib sau ua ke ntawm qhov chaw ua haujlwm los ua ib zaj duab xis; thiab electroosmosis tshem tawm cov dej ntau dhau thiab impurities thaum tsim cov yeeb yaj kiab, txhim kho zaj duab xis ntom ntom. Kev ci thiab kho ntxiv txhawb nqa cov ntoo khaub lig- txuas, tsim cov txheej tiv thaiv tawv thiab ruaj khov. Cov tshuab sib txawv, xws li anodic thiab cathodic electrophoresis, sib txawv hauv hom resin thiab siv tau cov substrates, nrog cathodic electrophoresis dhau los ua qhov kev xaiv tseem ceeb vim nws txoj kev tiv thaiv corrosion zoo dua.
Nrog kev nce qib hauv cov khoom siv thev naus laus zis, cov txheej txheem electrophoretic tau hloov zuj zus mus rau kev nkag siab dua, kev siv hluav taws xob qis dua, thiab ntau dua kev ua haujlwm. Qee lub tshuab tshiab ua ke cov pob zeb nti tiv thaiv, kua qaub los nag, thiab tus kheej - ntxuav cov khoom kom ua tau raws li cov kev cai nruj ntawm cov tsheb tshiab thiab cov khoom siv siab - kawg. Nyob rau tib lub sijhawm, kev txhim kho ntawm qis- qhov kub thiab txias formulations yog txo lub zog noj thiab nthuav lawv daim ntawv thov muaj peev xwm ntawm tshav kub- rhiab substrates xws li yas thiab lub teeb yuag alloys.
Zuag qhia tag nrho, electrophoretic txheej, nrog rau lawv cov kev zoo ntawm cov yeeb yaj kiab tuab, kev tiv thaiv kev ruaj ntseg, thiab ib puag ncig tus phooj ywg, tau dhau los ua txoj kev kho deg tsis tseem ceeb hauv kev tsim khoom niaj hnub no. Lawv tsis tsuas yog tswj hwm cov ntsiab lus tiv thaiv ntawm cov txheej txheem ib txwm muaj tab sis kuj txhim kho qhov tseeb thiab kev ua haujlwm zoo los ntawm kev tsav tsheb hluav taws xob, muab kev txhawb nqa rau lub sijhawm ntev - lub sijhawm ua haujlwm ntev thiab ruaj khov ntawm cov khoom lag luam.
