Electrophoresis finishing txheej txheem yog stainless hlau kev lag luam ib qho kev kho deg, electrophoresis nyob rau hauv 1807 los ntawm ib tug Lavxias teb sab tsev kawm ntawv lub npe hu ua Ferdinand Frederick Royce nrhiav tau xib fwb, tab sis nyob rau hauv lub midst ntawm lub ntiaj teb no kev lag luam technology yog tsawg, tsis muaj peev xwm los tsim ib zaj duab xis txog electrophoresis technology ntawm cov cuab yeej, xws li ib tug predicament lasted ntau tshaj 100 AW ib puas xyoo tus txiv neej, mus txog rau thaum lub npe hu ua Swedish tus txiv neej. uz cov kws tshawb fawb tau tsim ib lub xov tooj ntawm tes interface electrophoresis apparatus, electrophoresis thev naus laus zis kuj yog nyob rau xyoo 6, 70 xyoo dhau los, Tom qab ntau xyoo ntawm kev txhim kho thiab nag lossis daus, yog li nws yog siv tiag tiag hauv kev lag luam.

Ua ntej tshaj plaws, kuv xav tham txog cov yam ntxwv thiab cov ntsiab lus ntawm qhov tshwm sim ntawm electrophoresis. Electrophoresis hais txog kev txav ntawm cov khoom xa mus rau lawv cov qauv electrode nyob rau hauv qhov kev txiav txim ntawm lub tshuab hluav taws xob. Feem ntau siv rau stainless hlau, aluminium alloy thiab lwm yam hlau, tuaj yeem ua rau cov khoom muaj ntau yam xim, hauv cov khoom siv raw tsis ua mob rau cov hlau luster, tab sis kuj tuaj yeem txhim kho qhov kev ua tau zoo ntawm nws cov khoom raw, thiab muaj zog corrosion kuj, nrog electroplating txheej txheem.

Nyob rau theem pib ntawm kev nrov ntawm electrophoretic technology, ford motor co., ltd. Hauv Tebchaws Meskas yog thawj zaug siv cov txheej txheem no, uas yog thawj zaug siv rau primer ntawm lub tsheb. Tom qab ntawd, vim qhov zoo tshaj plaws los tiv thaiv corrosion thiab tiv thaiv xeb muaj peev xwm ntawm electrophoretic technology, cov cuab yeej no tau nyiam los ntawm cov thawj coj tub rog, thiab tsis ntev tau siv dav hauv kev lag luam tub rog.Txawm li cas los xij, vim muaj ntau yam teeb meem, xws li kev ruaj ntseg ntawm cov cuab yeej technology thiab blockade ntawm lub sij hawm, electrophoretic technology tsis tau nrov, thiab nws tsis tau siv nyob rau hauv lub teb ntawm niaj hnub hardware 20 xyoo dhau los.

Cov txheej txheem tseem ceeb ntawm electrophoresis: pretreatment, electrophoresis, ziab

Pretreatment kuj yog qhov zoo tshaj plaws taw tes nyob rau hauv tag nrho cov txheej txheem, tag nrho pretreatment roughly muaj: roj tshem tawm, xeb tshem tawm, phosphating, peb theem me me.

Feem ntau ntawm cov kev daws teeb meem siv rau kev tshem tawm cov roj yog thermal alkaline chemical roj tshem tawm cov kev daws teeb meem, qhov ntsuas kub yog tswj tau ntawm 60 ℃ (steam cua sov), lub sij hawm yog tswj ntawm li 20 feeb, thiab tom qab ntawd ntxuav lub substrate nrog dej kub ntawm 60 ℃ rau ob feeb.

Tom qab ntawd yog lub derusting, feem ntau yuav siv hydrochloric acid derusting kua rau ntawm lub phaj derusting, thiab tom qab ntawd nrog cov tshuaj ntxuav hauv chav sov li 10 mus rau 20 feeb.Yau nrog dej txias rau lwm feeb.

Tom qab ntawd siv 60 ℃ phosphating kua rau phosphating phaj rau 10 feeb, thiab tom qab ntawd siv cov tshuaj nrog phosphating kua kom passivate ntawm chav tsev kub rau 1 ~ 2 feeb.Yog li tag nrho cov txheej txheem ua ntej ua tiav.
