Electroplating pretreatment yog lub hauv paus ntawm electroplating thiab tus yuam sij los xyuas kom meej qhov zoo ntawm kub plating hlau.Yog tias lub substrate tsis raug kho raws li qhov yuav tsum tau ua ua ntej electroplating, txawm tias muaj cov tshuaj electroplating zoo, cov khoom siv hluav taws xob tsim nyog thiab cov khoom siv rau kev tswj cov txheej txheem electroplating, nrog rau cov neeg txawj ntse heev, nws tsis tuaj yeem tau txais cov txheej txheem electroplating kom tau raws li qhov yuav tsum tau ua.
Ua ntej plating tsis yog tsuas yog tshem tawm cov hlau matrix, thiab lub hav zoov ntawm cov roj thiab cuam tshuam rau txheej adhesion thiab lwm yam kev xav tau zoo ntawm cov khoom txawv teb chaws, kuj xav kom tshem tawm cov oxide nto, ua kom nws muaj kev huv huv thiab kev ua haujlwm saum npoo, kom ntseeg tau tias cov txheej txheem. thiab cov substrate ruaj khov nrog, raws li qhov yuav tsum tau ua ntawm cov tsos ntawm plating, qee zaum yuav ua rau qee qhov kev kho tshwj xeeb ua ntej plating.
Cov kev pab cuam thiab kev pab lub neej ntawm electrogalvanized hlau los yog cov khoom muaj feem xyuam nrog cov plating thickness.Qhov kev siv nruj dua thiab qhov kev pab cuam lub neej ntev dua, lub thickness yuav tsum tau galvanizing txheej.Cov khoom sib txawv, raws li ib puag ncig tshwj xeeb (kub, av noo, dej nag, atmospheric muaj pes tsawg leeg, thiab lwm yam) los txiav txim siab qhov kev pab cuam lub neej ntawm electroplating thickness, dig muag thickening yuav ua rau ntau yam pov tseg.Tab sis yog tias lub thickness tsis txaus, nws yuav tsis ua tau raws li qhov xav tau ntawm kev pabcuam lub neej.
Cov tuam txhab sib txawv, raws li lawv tus kheej cov khoom siv, thaum txiav txim siab hom plating, thawj zaug suav nrog cov txheej txheem ua tiav thiab tsim nyog, cov txheej txheem plating meej, tswj plating tov concentration, kev ua haujlwm txheem.Kev kho tom qab plating rau lub hom phiaj ntawm kev txhim kho kev tiv thaiv, kho kom zoo nkauj thiab lwm yam tshwj xeeb ntawm plating qhov chaw.Tom qabgalvanizing, chromate passivation, los yog lwm yam kev kho mob hloov dua siab tshiab feem ntau yuav tsum tau tsim cov hom kev hloov dua siab tshiab, uas yog ib qho ntawm cov txheej txheem tseem ceeb los xyuas kom meej qhov zoo ntawm cov plating.
