Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm electrophoretic txheej?

^{Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm electrophoretic txheej?}

^{Electrophoretic txheej yog txawv los ntawm electroplating nyob rau hauv cov nqe lus ntawm conductivity ntawm electrodeposited cov ntaub ntawv, ntxiv rau cov nyhuv ntawm hluav taws xob teb nyob rau hauv dav inorganic electrolytes. Thaum electroplating, cov conductivity tseem tsis hloov tom qab electrodeposition. Organic coatings, vim lawv cov khoom insulating, muaj kev hloov pauv tseem ceeb hauv kev tiv thaiv thaum lub sij hawm electrophoresis thaum siv electrophoretic txheej rau cov dej-raws li txheej.}

^{Thaum pib ntawm electrophoresis, dot zoo li tso nyiaj thawj zaug tshwm sim, maj mam txuas los ntawm daim tawv nqaij flaps. Raws li electrophoresis txuas ntxiv mus, cov electrodeposit yog ib feem ntawm cov rwb thaiv tsev, thiab tom qab qhov kev tiv thaiv nce mus rau qee qhov, electrophoresis tsis tshua muaj tshwm sim hauv I. Cov hluav taws xob xa hluav taws xob maj mam hloov mus rau n kev taw qhia kom txog thaum lub npoo yog coated tag.}

^{Hlau workpieces yog coated nrog electrophoretic txheej tshuab, uas muaj ntau yam ntxwv piv rau ib txwm siv systems.}

^{1. Electrophoretic txheej yog tag nrho cov tshuab thiab automated, uas tsis tsuas yog txo kev siv zog, tab sis kuj tseem txhim kho kev ua haujlwm zoo, ua rau nws tsim nyog rau kev sib dhos ua haujlwm loj. Cov txheej txheem electrophoretic yog qhov ua tau zoo heev, uas tuaj yeem txuag kev ua haujlwm thiab dhau los ua cov txheej txheem zoo rau kev txo nqi vim kev siv hluav taws xob tsawg. Automation muab kev txuas ntxiv hauv kev tsim khoom. Qhov no txhais tau hais tias qhov tshwm sim ntawm cov khoom puas tshwm sim tau txo qis heev.}

^{2. High permeability, kiag li soluble nyob rau hauv dej los yog emulsion, tsis tshua muaj viscosity tom qab tsim nrog tank tov, yooj yim rau nkag mus rau hauv lub hnab qauv thiab qhov khoob ntawm cov txheej, tshwj xeeb tshaj yog haum rau txheej txheej ntawm cov khoom siv tsis xwm yeem.}

^{3. Electrophoresis da dej muaj kev ua haujlwm siab, thiab cov txheej txheem tuaj yeem ua luam dej sai hauv qab hluav taws xob. Tom qab neutralization ntawm txheej txheej, ib qho hluav taws xob nruab nrab ntub zaj duab xis yog tsim, uas ua rau cov xim ntub dej ntub dej, ua kom tsis muaj zog, thiab txo qhov tso tawm ntawm cov xim pleev xim, tsim cov xim sib txawv thiab tuab. Los ntawm kev xaiv electrophoretic txheej ntau yam thiab kho cov mob electrophoretic,}

^{4. Kev siv cov txheej txheem tuaj yeem ncav cuag ntau dua 95%, lossis txawm tias 100%. Vim tias cov ntsiab lus tsis tshua muaj siab thiab viscosity ntawm cov roj, muaj cov txheej txheem tsawg dua los ntawm cov khoom siv coated, tshwj xeeb tshaj yog tom qab siv ultrafiltration (UF) thiab thim rov qab osmosis (RO) thev naus laus zis, txheej txheej txheej txheej txheej kaw kaw yog siv, ua rau tus nqi rov qab siab.}

^{5. Cov txheej txheej muaj peev xwm tiv thaiv corrosion thiab yog ib qho yeeb yaj kiab hauv qab hluav taws xob, uas tuaj yeem txhim kho corrosiveness ntawm sab hauv kab noj hniav, vuam, thiab cov npoo ntawm lub workpiece. Lub 20 hli tuab anodic electrophoretic txheej muaj ntsev tsis kam tshaj 300h, uas tuaj yeem ua rau cov ntsev tsuag kev ua haujlwm hauv cov yeeb yaj kiab ntau dua 500h, thiab txawm tias ncav cuag tshaj 1000h.}

^{Tau kawg, electrophoretic txheej kuj muaj cov kev txwv hauv qab no:}

^{1. Cov txheej txheem electrophoretic yuav tsum tau ua raws li cov khoom siv hluav taws xob, yog li nws tsuas yog tsim nyog rau cov khoom siv txheej txheej. Cov khoom uas tsis muaj hluav taws xob xws li ntoo, yas, roj hmab, thiab daim ntaub tsis tuaj yeem pleev xim siv txoj kev no.}

^{2. Cov coatings uas muaj ntau yam hlau uas sib txawv conductivity yuav tsum tsis txhob siv electrophoretic txheej tshuab. Qee cov txheej txheej electrophoretic yuav ua rau muaj kev tsis haum rau cov hlau ions xws li Cn thiab Sn.}
