Cheebtsam ntawm electrophoretic txheej ntau lawm kab

Electrophoretic txheej yuav tsum tau siv cov xim electrophoretic, tseem hu ua dej-soluble txheej. Cov xim electrophoretic thiab dej distilled yuav tsum tau diluted nyob rau hauv ib qho kev faib ua ntej siv.

Electrophoretic txheej feem ntau suav nrog plaub txheej txheem ib txhij:

1. Electrophoresis: Nyob rau hauv qhov kev txiav txim ntawm cov hluav taws xob ncaj qha tam sim no, qhov zoo thiab qhov tsis zoo ntawm cov khoom siv colloidal txav mus rau hauv cov lus qhia tsis zoo thiab zoo, los yog ua luam dej.

2. Electrolysis: Oxidation txo cov tshuaj tiv thaiv tshwm sim ntawm cov electrodes, uas ua rau tsim oxidation thiab txo phenomena ntawm cov electrodes.

3. Electrodeposition: Vim electrophoresis, them cov khoom colloidal uas txav mus rau thaj tsam ntawm lub anode tso electrons nyob rau hauv template nto thiab deposit nyob rau hauv ib tug insoluble lub xeev, uas ua rau tsim ib tug xim zaj duab xis.

4. Electroosmosis: Qhov tshwm sim nyob rau hauv uas cov khoom theem tseem nyob ruaj khov thaum lub sij hawm ua kua txav nyob rau hauv qhov kev txiav txim ntawm ib qho hluav taws xob teb. Electroosmosis maj mam tso cov dej noo uas muaj nyob hauv cov xim pleev xim rau sab nraud, tsim cov xim pleev xim uas yuav luag tsis muaj tam sim no dhau los, cov ntsiab lus tsis tshua muaj dej noo, thiab ua haujlwm siab.

5. Siv hlau liab epoxy electrophoretic xim ua piv txwv: Cov xim electrophoretic no yog tsim los ntawm kev hloov kho epoxy resin, butanol, ethanolamine, talc hmoov, thiab hlau liab. Tom qab sib tov nrog dej distilled, cov xim electrophoretic tau muab cais ua qhov zoo cations thiab tsis zoo them anions nyob rau hauv qhov kev txiav txim ntawm cov hluav taws xob ncaj qha tam sim no, thiab dhau mus ua ib qho kev hloov ntawm lub cev, tshuaj, colloid, tshuaj, thiab electrochemical hloov.

Cov txheej txheem thiab cov txheej txheem rau hluav taws xob swimsuits

(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 # 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 pom, feem ntau siv thawj theem pom, thiab cov lim dej yog lub hnab mesh qauv 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 pleev xim zoo, lub hnab lim 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 kab hluav taws xob electrophoresis nrog cov khoom tsim tawm txhua xyoo ntawm 300000 steel rings ua piv txwv, kev tswj xyuas kev siv lub tank yog qhov tseem ceeb heev. Ntau yam tsis tu ncua ntawm lub tank tov yog kuaj tsis tu ncua, thiab lub tank tov tau 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.

Kev siv cov txheej txheem electrophoretic thiab cov xim pleev xim dej ua rau muaj kev vam meej hauv kev lag luam txheej txheej.

Electrophoretic txheej muaj kev tsim kho ceev ceev, uas tuaj yeem ua tiav kev siv tshuab thiab kev ua haujlwm tsis tu ncua, txo kev siv zog, cov xim pleev xim tsis zoo, muaj zog adhesion, thiab tuaj yeem tau txais cov xim sib xws, tiaj tus, thiab cov xim pleev xim rau cov cheeb tsam uas nyuaj lossis tsis zoo los ntawm txheej txheej. txoj kev, xws li rib phaj welds thiab lwm qhov chaw hais ua ntej. Kev siv tus nqi ntawm cov txheej yog siab li 90% -95%, vim cov txheej electrophoretic yog

Dej, raws li cov kuab tshuaj, muaj qhov zoo ntawm qhov tsis muaj nplaim taws, tsis muaj tshuaj lom, thiab ua haujlwm yooj yim. Cov xim zaj duab xis qhuav tom qab electrophoresis tau zoo heev adhesion, thiab nws cov xeb kuj, corrosion kuj, huab cua tsis kam, thiab lwm yam khoom yog superior rau cov xim zoo tib yam thiab kev tsim kho.
