Kub dipgalvanized hlau hlauyog tsim los ntawm hlau pas nrig tom qab kos duab, cua sov, thiab tom qab ntawd kos duab, Z los ntawm kub dip txheej txheem nto coated nrog zinc.Tus nqi ntawm zinc feem ntau yog tswj nyob rau hauv thaj tsam ntawm 30g / m^ 2-290g / m^2 raws li qhov xav tau ntawm ib puag ncig siv.Vim tias cov khoom tsim los ntawm cov txheej txheem kub dip galvanizing muaj lub neej ntev anticorrosive thiab dav siv ib puag ncig, kub dip galvanizing hlau hlau yog dav siv hauv kev lag luam hnyav, lub teeb kev lag luam, kev ua liaj ua teb thiab lwm yam kev lag luam hauv daim ntawv net, hlua, hlau thiab lwm yam.
Kub dip galvanizing tseem hu ua kub dip zinc thiab kub dipgalvanizing: nws yog ib txoj kev zoo ntawm hlau anticorrosion, feem ntau yog siv nyob rau hauv ntau yam industries ntawm hlau qauv chaw.Nws yog txhawm rau txhawm rau cov hlau qhov chaw tom qab xeb tshem tawm mus rau hauv cov tshuaj zinc melted ntawm li 500 ℃, kom cov neeg sab nrauv ntawm cov hlau txuas nrog zinc txheej, thiaj li ua si lub hom phiaj ntawm kev tiv thaiv corrosion.Kub dip galvanizing txheej txheem: tiav cov khoom pickling - ntxuav - ntxiv plating tov - ziab - dai plating - txias - tshuaj - ntxuav - polishing - kub dip galvanizing tiav.
Kub plating hlau tseem hu ua kub dip zinc thiab kub dipgalvanized hlau, yog ua los ntawm hlau pas nrig los ntawm kev kos duab, cua sov, thiab tom qab ntawd kos duab, thaum kawg los ntawm kub plating txheej txheem nto coated nrog zinc thiab zus tau tej cov hlau.Zinc ntau yog feem ntau tswj hauv 30g / m^2-290g / m^2 nplai.Feem ntau siv nyob rau hauv ntau yam lag luam ntawm cov khoom siv hlau.Nws yog txhawm rau txhawm rau cov hlau qhov chaw tom qab xeb tshem tawm mus rau hauv cov kua zinc melted ntawm li 500 ℃, kom cov neeg sab nrauv ntawm cov hlau txuas nrog zinc txheej, thiab tom qab ntawd ua si lub hom phiaj ntawm kev tiv thaiv corrosion.
Passivation, kub melting, kaw thiab dehydrogenation ntawm kub-dipgalvanized hlautom qab plating rau txhim khu kev tiv thaiv, kho kom zoo nkauj thiab lwm yam tshwj xeeb lub hom phiaj.Chromic acid ntsev passivation lossis lwm yam kev hloov pauv feem ntau yog ua tiav tom qab galvanizing, cov yeeb yaj kiab hloov pauv uas tsim cov hom sib xws yog ib qho ntawm cov txheej txheem ua haujlwm tseem ceeb uas ua kom zoo tom qab plating.
