(1) Cov txheej txheem ntws ntawm electrophoretic txheej ntawm cov hlau dav dav yog: ua ntej tu → online → degreasing → dej ntxuav → xeb tshem tawm → dej ntxuav → neutralization → dej ntxuav → phosphating → dej ntxuav → passivation → electrophoretic txheej → tank tu → ultrafiltration dej ntxuav → ziab → offline.
(2) Lub substrate thiab pre-kho ntawm cov khoom coated muaj ib qho kev cuam tshuam tseem ceeb ntawm electrophoretic txheej zaj duab xis. Castings feem ntau derusted los ntawm sandblasting los yog tua blasting, nrog paj rwb xov paj siv los tshem tawm cov plua plav ntab saum npoo ntawm lub workpiece, thiab 80 # mus rau 120 # sandpaper siv los tshem tawm cov pob hlau seem thiab lwm cov khib nyiab ntawm qhov chaw. Cov hlau nto yog kho nrog degreasing thiab xeb tshem tawm. Thaum cov kev xav tau saum npoo siab dhau lawm, phosphating thiab passivation nto kho tau ua tiav. Dub hlau workpieces yuav tsum tau kho phosphating ua ntej anodic electrophoresis, txwv tsis pub corrosion kuj ntawm cov xim zaj duab xis yuav tsis zoo. Thaum phosphating, zinc ntsev phosphating zaj duab xis nrog ib tug tuab ntawm txog 1-2 μ m feem ntau yog siv, thiab crystallization ntawm phosphating zaj duab xis yuav tsum tau zoo thiab uniform.
(3) Hauv cov txheej txheem lim, feem ntau siv cov lim dej, uas yog lub hnab ntim mesh nrog lub pore loj ntawm 25-75 μ m. Cov txheej txheej electrophoretic yog thauj los ntawm lub twj tso kua mis ntsug mus rau lub lim kom pom. Xav txog yam xws li hloov lub voj voog thiab cov xim zoo nkauj, lub hnab lim Z nrog lub pore loj ntawm 50 μ m yog qhov nyiam. Nws tsis tsuas yog ua tau raws li qhov yuav tsum tau ua ntawm cov xim zoo nkauj, tab sis kuj daws qhov teeb meem ntawm lub hnab lim lim.
(4) Lub voj voog ntim ntawm cov txheej txheem electrophoretic ncaj qha cuam tshuam rau kev ruaj ntseg ntawm cov tshuaj tank thiab qhov zoo ntawm cov xim zaj duab xis. Ua kom lub ntim ntim, txo cov sedimentation thiab npuas ntawm lub tank tov; Tab sis kev laus ntawm cov kua tank nrawm dua, kev siv hluav taws xob nce ntxiv, thiab kev ruaj ntseg ntawm cov tshuaj tank deteriorates. Nws yog qhov zoo tshaj plaws los tswj cov kev siv ntau zaus ntawm lub tank tov rau 6-8 zaug / h, uas tsis tsuas yog ua kom cov xim zoo nkauj ntawm cov yeeb yaj kiab, tab sis kuj ua kom muaj kev ruaj ntseg ntawm cov tshuaj tank.
(5) Nrog rau kev ncua sij hawm ntau lawm, qhov impedance ntawm anode diaphragm yuav nce, thiab qhov ua haujlwm tau zoo yuav txo qis. Yog li ntawd, nyob rau hauv ntau lawm, lub zog ua hauj lwm ntawm lub hwj chim mov yuav tsum maj mam nce raws li qhov voltage poob qhov teeb meem los them rau qhov voltage poob ntawm lub anode diaphragm.
(6) Lub kaw lus ultrafiltration tswj cov concentration ntawm impurity ions nkag mus rau hauv lub workpiece los xyuas kom meej txheej zoo. Thaum lub sijhawm ua haujlwm ntawm cov txheej txheem no, nws yuav tsum tau muab sau tseg tias lub kaw lus yuav tsum khiav tsis tu ncua tom qab kev ua haujlwm, thiab kev ua haujlwm tsis tu ncua yog nruj me ntsis txwv tsis pub tiv thaiv ultrafiltration membrane kom qhuav. Cov tawv nqaij qhuav thiab cov xim ua raws li ultrafiltration membrane thiab tsis tuaj yeem ntxuav kom huv si, uas yuav cuam tshuam rau permeability thiab kev pab cuam lub neej ntawm ultrafiltration membrane. Tus nqi effluent ntawm ultrafiltration membrane txo nrog lub sij hawm khiav, thiab nws yuav tsum tau ntxuav ib zaug txhua 30-40 hnub kom paub meej tias cov dej ultrafiltration yuav tsum tau rau ultrafiltration immersion thiab flushing.
(7) Cov txheej txheem electrophoretic yog tsim rau cov txheej txheem sib dhos loj. Lub voj voog hloov tshiab ntawm electrophoresis da dej tov yuav tsum tsis pub dhau 3 lub hlis. Noj cov khoom siv hluav taws xob electrophoresis nrog cov khoom tsim tawm txhua xyoo ntawm 300000 steel rings ua piv txwv, kev tswj xyuas kev tshawb fawb ntawm cov tshuaj tank yog qhov tseem ceeb. Ntau yam tsis tu ncua ntawm lub tank tov yog kuaj tsis tu ncua, thiab lub tank tov yog hloov kho thiab hloov raws li qhov ntsuas tau. Feem ntau, qhov tsis sib xws ntawm lub tank tov yog ntsuas ntawm cov zaus hauv qab no: tus nqi pH, cov ntsiab lus ntawm cov khoom siv, thiab cov khoom siv hluav taws xob electrophoresis, ultrafiltration thiab ultrafiltration ntxuav kua, cathode (anode) tov, circulating ntxuav kua, thiab deionized tu tshuaj ib hnub ib zaug. ; Yanji piv, cov ntsiab lus organic hnyav, thiab kuaj lub tank me me tau ua ob zaug hauv ib lub lis piam.
(8) Kev tswj cov xim zoo nkauj yuav tsum tsis tu ncua xyuas qhov sib xws thiab tuab ntawm txheej, thiab yuav tsum tsis txhob muaj pinholes, sagging, txiv kab ntxwv tev, wrinkles lossis lwm yam tshwm sim ntawm qhov tsos. Cov ntsuas lub cev thiab tshuaj lom neeg xws li adhesion thiab corrosion kuj ntawm cov txheej yuav tsum tau xyuas tsis tu ncua. Kev tshuaj xyuas lub voj voog yog nyob ntawm cov chaw tsim khoom cov qauv tshuaj ntsuam xyuas, thiab feem ntau txhua pawg yuav tsum tau sim.
