1. Electroplating txheej txheem tswj
Qhov kev pab cuam thiab kev pab lub neej ntawmgalvanized hlau hlaulos yog cov khoom muaj feem cuam tshuam nrog lub thickness ntawm txheej.Qhov kev siv nruj dua thiab qhov kev pab cuam lub neej ntev dua, lub thickness yuav tsum yog txheej txheej ntawm galvanized hlau hlau.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 lub neej kev pab cuam ntawm txheej thickness, qhov muag tsis pom kev yuav ua rau txhua yam pov tseg.Tab sis yog tias lub thickness tsis txaus, nws yuav tsis ncav cuag qhov kev xav tau ntawm kev pab cuam lub neej.Cov tuam txhab sib txawv, raws li lawv tus kheej cov khoom siv, nyob rau hauv cov ntaub ntawv ntawm kev txiav txim siab plating, thawj qhov kev npaj ntawm cov txheej txheem ntau dua thiab tsim nyog txaus, cov txheej txheem plating meej, tswj plating tov concentration, kev ua haujlwm txheem.
2, kub plating hlau plating tom qab ua
Kev kho tom qab plating (passivation, kub melting, sealing thiab hydrogen tshem tawm, thiab lwm yam) rau lub hom phiaj ntawm kev txhim kho cov khoom tiv thaiv, kho kom zoo nkauj thiab lwm yam tshwj xeeb lub hom phiaj.Tom qab galvanized, chromate passivation los yog lwm yam kev kho mob hloov dua siab tshiab yog feem ntau yuav tsum tau los ua tus coj hom conversion zaj duab xis, uas yog ib qho ntawm cov txheej txheem tseem ceeb los xyuas kom meej qhov zoo ntawm post-plating.
3, galvanized hlau galvanized txheej txheem
Rau qhov tseem ceeb thiab cov khoom tseem ceeb nrog lub zog tensile ntau dua 1034Mpa, qhov kev ntxhov siab yuav tsum raug tshem tawm ntawm 200 ± 10 ℃ rau ntau tshaj 1 teev ua ntej plating, thiab rau carburized lossis nto hardened qhov chaw, qhov kev ntxhov siab yuav tsum raug tshem tawm ntawm 140 ± 10 ℃ rau ntau dua tshaj 5 teev.Tus neeg saib xyuas siv los ntxuav yuav tsum tsis muaj kev cuam tshuam rau lub zog ntawm cov txheej txheej thiab tsis muaj corrosion ntawm lub substrate.Acid activation Acid activation solution yuav tsum muaj peev xwm tshem tawm cov khoom siv corrosion thiab oxide zaj duab xis (daim tawv nqaij) ntawm qhov chaw uas tsis muaj corrosion ntau dhau ntawm matrix.
Galvanizing tuaj yeem ua los ntawm zincate galvanizing lossis chloride galvanizing.Cov tshuaj ntxiv tsim nyog yuav tsum tau siv kom tau txais cov txheej txheem uas ua tau raws li qhov yuav tsum tau ua ntawm tus qauv no.Kev kho lub teeb yuav tsum tau ua tom qab lub teeb plating.Cov khoom uas yuav tsum tau dehydrogenated rau passivation yuav tsum tau passivated tom qab dehydrogenation.Ua ntej passivation, 1% H2SO4 lossis 1% hydrochloric acid yuav tsum tau siv rau kev ua kom 5 ~ 15s.Passivation yuav tsum tau kho nrog cov xim chromate tshwj tsis yog tias tau teev tseg hauv 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 ntawm cov hlau hlau tseem tsis 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.
