Loj lojl galvanized hlauyog dav siv nyob rau hauv kev xyaum.Hlau hlau kuj muaj qee yam teeb meem, yooj yim rau xeb thiab corrosion.Yog li, txoj kev galvanized feem ntau tuaj yeem siv los tiv thaiv corrosion ntawm cov khoom.Ntxiv rau txoj kev no, feem ntau siv cov txheej txheem kev kho hlau thiab kev kho phosphating, kev kho oxidation, thiab lwm yam. Hlau phosphating kev kho mob: hlau thiab hlau cov khoom rau roj, xeb tshem tawm, mus rau hauv ib tug tshwj xeeb muaj pes tsawg leeg ntawm acid kua immersion, muaj peev xwm tsim ib txheej ntawm insoluble. acid zaj duab xis ntawm cov hlau nto, cov txheej txheem no hu ua phosphating kev kho mob.
Roll lojgalvanized hlauphosphating zaj duab xis yog tsaus grey rau dub grey, lub thickness feem ntau yog 5-20μm, nyob rau hauv cov huab cua muaj corrosion kuj zoo.Membrane yog cov qauv microporous, xws li cov xim muaj peev xwm adsorption muaj zog, xws li siv cov xim hauv qab txheej, corrosion kuj tuaj yeem ua tau zoo dua.Hlau oxidation kev kho mob: cov khoom hlau tau ntxiv rau qhov sib xyaw ntawm NaOH thiab NaNO2 tov, kev kho cua sov, nws qhov chaw tuaj yeem tsim cov txheej tuab ntawm 0.5-1.5.μm ntawm xiav oxide zaj duab xis, thiaj li yuav 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 lubricity thiab tsis cuam tshuam qhov precision ntawm qhov chaw.Yog li ntawd, precision instruments thiab kho qhov muag ntsuas qhov chaw, caij nplooj ntoos hlav steel, nyias steel ntawv, nyias steel hlau thiab lwm yam feem ntau siv xiav ua.Loj yob galvanized hlau feem ntau siv galvanized kev kho mob, yog sib npaug los tsim cov txheej txheem tiv thaiv ntawm qhov chaw ntawm cov hlau, feem ntau siv.kub galvanizing, kub txau, nqus plating thiab lwm txoj kev, ntau txoj kev muaj cov yam ntxwv sib xws.
