Cov kev pab cuam thiab kev pab lub neej ntawmelectrogalvanized hlau hlaulos yog tivthaiv yog ze ze rau lub thickness ntawm electroplating txheej.Qhov kev siv nruj dua thiab qhov kev pab cuam lub neej ntev dua ntawm cov hlau plating, qhov tuab ntawm electrogalvanizing hlau txheej yuav tsum tau ua.Cov khoom sib txawv, raws li ib puag ncig tshwj xeeb los txiav txim siab qhov kev pab cuam lub neej ntawm electroplating thickness, qhov muag tsis pom kev yuav ua rau txhua yam pov tseg, tab sis yog tias lub thickness tsis txaus, thiab yuav tsis ncav cuag qhov kev xav tau ntawm lub neej kev pab cuam.
Cov tuam txhab sib txawv raws li lawv tus kheej cov khoom siv, thaum txiav txim siab txog hom plating, los npaj cov txheej txheem ntau dua thiab tsim nyog, cov txheej txheem tsis meej electroplating, tswj cov concentration ntawm cov tshuaj electroplating, cov txheej txheem ua haujlwm.Plating post kev kho mob rau txhim khu kev tiv thaiv, kho kom zoo nkauj thiab lwm yam tshwj xeeb lub hom phiaj.Tom qabgalvanizing, chromate passivation los yog lwm yam kev hloov pauv kev kho mob feem ntau yog ua los ntawm cov khoom sib xws ntawm cov yeeb yaj kiab hloov dua siab tshiab, uas yog ib qho ntawm cov txheej txheem tseem ceeb los xyuas kom meej qhov zoo ntawm cov plating.
Galvanized hlautxheej txheem galvanizing: tshem tawm kev ntxhov siab ua ntej plating qhov twg lub zog tensile ntau dua 1034Mpa qhov tseem ceeb, qhov tseem ceeb ua ntej plating yuav tsum nyob ntawm 200 ± 10 ℃ kom tshem tawm kev ntxhov siab rau ntau tshaj 1 teev, carburizing lossis deg hardening yuav tsum nyob ntawm 140 ± 10 ℃ kom tshem tawm kev ntxhov siab rau ntau tshaj 5 teev.Tus neeg saib xyuas siv los ntxuav yuav tsum tsis muaj kev cuam tshuam rau lub zog ntawm cov txheej txheem thiab tsis muaj corrosion rau lub matrix.Acid activation Acid activation kua yuav tsum muaj peev xwm tshem tawm cov khoom xeb ntawm qhov chaw, oxide zaj duab xis (tawv tawv), tsis dhau corrosion rau lub matrix.
Zinc plating tuaj yeem ua zinc plated nrog zincate lossis chloride, cov khoom siv tsim nyog yuav tsum tau siv kom tau txais cov txheej txheem uas ua tau raws li cov qauv no.Tom qab lub teeb plating, kev kho lub teeb yuav tsum tau nqa tawm.Passivating qhov uas yuav tsum tau dehydrogenated yuav tsum passivated tom qab dehydrogenation.Ua ntej passivating, 1% H2SO4 lossis 1% hydrochloric acid yuav tsum tau qhib rau 5 ~ 15s.Passivation yuav tsum tau ua nrog cov xim chromate tshwj tsis yog tias tau teev tseg rau ntawm cov duab kos duab.
Daim ntawv thov dav ntawm galvanized hlau tau coj kev yooj yim rau tib neeg kev tsim khoom thiab lub neej, tab sis cov txheej txheem ntau lawmhlau hlautsis yog yuav tsum tau underestimated.Hauv kev tsim khoom, cov txheej txheem ntawm galvanized hlau yuav tsum tau tswj nruj me ntsis kom ntseeg tau qhov zoo ntawm galvanized hlau.
