Loj yob galvanized hlau yog siv cov pa roj carbon tsawg hlau ua, tom qab kos duab, pickling xeb tshem tawm, kub annealing, cua txias thiab lwm yam txheej txheem, nyob rau hauv kev siv yog ntau dav.Qhov kub ntawm cov yob loj galvanized hlau rau electroplating yuav tsum tau tswj ntawm 30 txog 50 ℃.Vim tias cov tshuaj chloride ions hauv chav da dej yog corrosive heev, quartz iav rhaub feem ntau yog siv.
Kev siv dav hauv kev xyaum, hlau hlau kuj muaj qee yam teeb meem, yooj yim xeb thiab corrosion, yog li peb tuaj yeem siv txoj kev galvanized los tiv thaiv cov khoom xeb.Ua ke nrog rau txoj kev no, hlau feem ntau siv txoj kev kho mob thiab phosphating kev kho mob, oxidation kev kho mob, thiab lwm yam. Hlau phosphating kev kho mob: hlau thiab hlau cov khoom kom tshem tawm cov roj, xeb, rau hauv ib tug tshwj xeeb muaj pes tsawg leeg ntawm cov ntsev tov, koj muaj peev xwm tsim ib txheej. ntawm dej soluble ntsev zaj duab xis nyob rau saum npoo ntawm cov hlau, cov txheej txheem no hu ua phosphating kev kho mob.
Loj yob galvanized hlau phosphating zaj duab xis yog tsaus grey rau dub grey, lub thickness yog feem ntau 5-20μm, muaj zoo corrosion kuj nyob rau hauv cov huab cua.Membrane yog cov qauv microporous, muaj zog adsorption muaj peev xwm pleev xim, xws li siv cov xim hauv qab, kev tiv thaiv corrosion tuaj yeem ua tau ntxiv.Kev kho cov hlau oxidation: Ntxiv cov khoom siv hlau rau NaOH thiab NaNO2 tov tshuaj, kev kho cua sov, qhov saum npoo tuaj yeem tsim cov txheej tuab ntawm li 0.5-1.5μm xiav oxide zaj duab xis, txhawm rau kom ncav cuag lub hom phiaj ntawm kev tiv thaiv corrosion, cov txheej txheem no hu ua xiav kev kho mob, hu ua xiav.
Cov oxide zaj duab xis no muaj ntau dua elasticity thiab lubrication, tsis cuam tshuam qhov tseeb ntawm qhov chaw.Yog li ntawd, qhov chaw ntawm precision instruments thiab optical instruments, caij nplooj ntoos hlav steel, nyias steel ntawv, zoo steel hlau thiab thiaj li nyob rau yog feem ntau bluing kev kho mob.Feem ntau siv galvanizing kev kho mob ntawm cov yob loj galvanized hlau yog sib npaug los tsim cov txheej txheem tiv thaiv ntawm qhov chaw ntawm cov hlau hlau.Cov kev siv feem ntau yog kub dip galvanizing, kub txau plating, nqus plating thiab lwm yam.Cov txheej txheem sib txawv muaj cov yam ntxwv sib xws.
