OEM siab precision stainless hlau ntawv hlau qhov chaw

Cov txheej txheem electrophoretic txheej txheem yog txheej txheej txheej uas siv cov hluav taws xob sab nraud los ua cov xim thiab cov khoom siv uas tau muab tshem tawm hauv cov kua electrophoretic tsiv mus nyob rau hauv ib qho kev taw qhia thiab tso rau ntawm qhov chaw ntawm lub substrate ntawm ib qho ntawm cov electrodes. Cia peb saib nws cov txheej txheem yooj yim ntws:

Txheej txheem txheej txheem

Electrophoretic txheej yog tsuas yog raws li electrophoresis thiab electrodeposition. Thaum lub sij hawm txheej txheem electrophoretic txheej, cov xim xim (resins thiab pigments) txav mus rau cathode nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb, thaum lub sij hawm tsis zoo nqi hais mus rau lub anode. Thaum cov khoom siv tau zoo (resins thiab pigments) ncav cuag qhov chaw ntawm cathode (cov khoom yuav tsum tau coated), lawv tau txais electrons thiab hnov ​​​​mob nrog hydroxide ions los ua dej-insoluble tshuaj, uas tso rau ntawm cathode (cov khoom yuav tsum tau ua. coated) los ua ib qho txheej txheem txheej txheej.

Txheej txheem muaj pes tsawg leeg

Cov txheej txheem electrophoretic feem ntau muaj plaub txheej txheem hauv qab no:

1. Pretreatment ua ntej txheej: suav nrog pre-tu, degreasing, xeb tshem tawm, neutralization, dej ntxuav, phosphating, passivation thiab lwm yam txheej txheem. Cov txheej txheem pretreatment no tseem ceeb heev rau qhov zoo thiab kev ua tau zoo ntawm txheej. Lawv xyuas kom meej tias qhov saum npoo ntawm cov khoom coated yog tsis muaj roj thiab xeb, thiab cov phosphate zaj duab xis yog densely thiab evenly crystallized.
2. Electrophoretic txheej: Tom qab pretreatment tiav lawm, lub workpiece yog immersed nyob rau hauv lub electrophoretic tank thiab electrophoretic txheej yog ua los ntawm ncaj qha tam sim no. Nyob rau hauv cov txheej txheem no, cov xim hais migrate directionally nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb thiab tso rau ntawm qhov chaw ntawm lub workpiece.
3. Kev ntxuav tom qab electrophoretic: Tom qab cov txheej txheem electrophoretic tiav, lub workpiece yuav tsum tau ntxuav kom tshem tawm cov kua tank thiab lwm yam impurities txuas rau saum npoo. Cov txheej txheem ntxuav feem ntau suav nrog cov kauj ruam xws li ntxuav lub tank thiab ntxuav dej ultrafiltration.
4. Qhuav ntawm electrophoretic txheej: Thaum kawg, lub workpiece coated nrog electrophoretic txheej yog qhuav kom solidify nws mus rau hauv ib tug nyuaj txheej. Qhov ziab kom qhuav thiab lub sijhawm nyob ntawm seb hom txheej siv thiab qhov yuav tsum tau ua ntawm lub workpiece.

Cov yam ntxwv txheej txheem

Cov txheej yog plump, uniform, tiaj tus, thiab du, nrog zoo zoo nkauj thiab tiv thaiv cov khoom.

Cov txheej txheej hardness, adhesion, corrosion kuj, cuam tshuam kev ua tau zoo, thiab kev nkag mus tau zoo dua li lwm cov txheej txheem txheej.
Kev siv cov xim dej-soluble, nrog dej raws li qhov nruab nrab dissolving, txuag ntau cov organic solvents, txo cov pa phem thiab ib puag ncig kev puas tsuaj.
Cov txheej txheem txheej yog siab, cov txheej poob yog me me, thiab cov txheej txheem siv tau ncav cuag 90% ~ 95%.

Txheej txheem parameter tswj

Cov txheej txheem txheej txheej electrophoretic muaj xws li cov tsis muaj xws li cov dej da dej, cov ntsiab lus ntawm cov hmoov tshauv, MEQ (tus naj npawb ntawm millimoles ntawm cov kua qaub yuav tsum tau rau 100 grams ntawm cov ntsiab lus ntawm cov xim) thiab cov ntsiab lus organic hnyav. Kev tswj hwm ntawm cov kev txwv no yog qhov tseem ceeb los xyuas kom meej qhov zoo thiab kev ua haujlwm ntawm txheej txheej. Nyob rau tib lub sijhawm, nws tseem yuav tsum tau ua tib zoo saib xyuas cov kev cuam tshuam ntawm cov yam ntxwv xws li kev xaiv ntawm qhov pom thiab qhov loj ntawm cov voj voog ntim ntawm kev ruaj ntseg ntawm cov kua da dej thiab qhov zoo ntawm cov xim zaj duab xis.

Cov kev ceev faj

Thaum lub sij hawm electrophoretic txheej txheej txheem, lub hwj huam mov yuav tsum ruaj khov kom tsis txhob muaj kev cuam tshuam ntawm voltage hloov ntawm lub txheej zoo.
Tsis tu ncua xyuas cov xwm txheej ntawm lub tank electrophoretic thiab cov khoom siv kom ntseeg tau tias lawv ua haujlwm li qub.
nruj me ntsis tswj cov txheej txheem txheej txheem electrophoretic los xyuas kom meej tias qhov zoo thiab kev ua tau zoo ntawm txheej ua tau raws li qhov yuav tsum tau ua.
Ua tib zoo saib xyuas kev ua haujlwm nyab xeeb kom tsis txhob muaj xwm txheej xws li hluav taws xob poob siab thiab hluav taws kub thaum lub sij hawm txheej txheej electrophoretic.
