Galvanized steel ntawv

Galvanized ntawv yog ib daim ntawv hlau uas nws nto yog coated nrog ib txheej ntawm zinc.Galvanizing yog ib qho txiaj ntsig zoo thiab muaj txiaj ntsig zoo tiv thaiv xeb uas siv hauv ntiaj teb rau li ib nrab ntawm lub ntiaj teb zinc ntau lawm.
Daim ntawv thov:
Galvanized steel phaj yog los tiv thaiv qhov saum npoo ntawm cov hlau phaj los ntawm corrosion mus rau nws cov kev pab cuam lub neej, coated nrog ib txheej ntawm hlau zinc nyob rau saum npoo ntawm cov hlau phaj, zinc coated steel phaj hu ua galvanized phaj.
Kev faib tawm

Raws li kev tsim khoom thiab kev ua tiav tuaj yeem muab faib ua pawg hauv qab no:
kub dip galvanized steel ntawv.Cov ntawv hlau yog immersed nyob rau hauv ib tug molten zinc da dej kom ua raws li zinc-plated steel ntawv rau saum npoo.Tam sim no, nws yog tsim los ntawm cov txheej txheem txuas ntxiv galvanizing, uas yog, coiled steel phaj txuas ntxiv mus rau hauv lub plating tank uas zinc yog yaj los ua ib daim ntawv hlau galvanized;
alloyed galvanized steel ntawv.Cov ntawv hlau no kuj yog tsim los ntawm kub dip, tab sis tam sim ntawd tom qab nws tawm, nws yog rhuab mus txog 500 ° C los ua ib tug alloy zaj duab xis ntawm zinc thiab hlau.Cov ntawv galvanized no muaj qhov zoo adhesion thiab weldability ntawm txheej;
electro-galvanized steel phaj.Kev tsim cov ntawv galvanized steel los ntawm electroplating muaj kev ua haujlwm zoo.Txawm li cas los xij, cov txheej txheej yog thinner thiab corrosion kuj tsis zoo li cov ntawv kub dip galvanized;
ib leeg-sided plating thiab ob-sided sib txawv galvanized steel.Ib sab galvanized steel, uas yog, ib yam khoom uas tsuas yog galvanized ntawm ib sab.Nws muaj qhov hloov tau zoo dua li ob sab galvanized ntawv hauv vuam, pleev xim, kho xeb thiab ua haujlwm.
Txhawm rau kom kov yeej qhov tsis txaus ntawm cov zinc tsis muaj coated ntawm ib sab, muaj ib daim ntawv galvanized coated nrog ib txheej nyias ntawm zinc ntawm lwm sab, uas yog, ib daim ntawv sib txawv ntawm ob sab galvanized;
alloy, composite galvanized steel ntawv.Nws yog ua los ntawm zinc thiab lwm yam hlau xws li txhuas, txhuas, zinc, thiab lwm yam, los yog cov hlau sib xyaw plated.Cov phaj hlau no muaj cov xeb zoo heev thiab cov txheej txheem zoo;
Ntxiv rau tsib hom saum toj no, kuj tseem muaj xim galvanized steel ntawv, luam ntawv galvanized steel ntawv, thiab polyvinyl chloride laminated galvanized steel nplooj ntawv.Txawm li cas los xij, cov khoom siv feem ntau tseem yog cov ntawv kub dip galvanized.
Cov khoom lag luam muaj feem cuam tshuam qhia cov qauv thickness, ntev thiab dav pom zoo rau cov nplooj ntawv galvanized thiab lawv cov kam rau ua.Feem ntau hais lus, qhov tuab ntawm daim ntawv galvanized yog, qhov loj dua qhov kam rau ua, tsis yog qhov ruaj khov 0.02-0.04 hli, lub thickness sib txawv kuj muaj cov kev xav tau sib txawv raws li kev tawm los, tensile coefficient, thiab lwm yam. Qhov ntev thiab dav sib txawv yog feem ntau. 5 hli, thickness ntawm daim ntawv.Feem ntau ntawm 0.4-3.2.
Nto
(1) Surface state: Cov ntawv galvanized muaj qhov sib txawv ntawm qhov chaw kho mob vim muaj ntau txoj kev kho mob hauv cov txheej txheem txheej, xws li paj zinc zoo nkauj, zoo zinc paj, paj zinc paj, paj dawb zinc thiab phosphating nto.Cov qauv German kuj tseem qhia cov theem saum npoo.
(2) Cov ntawv galvanized yuav tsum muaj qhov zoo nkauj thiab yuav tsum tsis txhob muaj qhov tsis zoo xws li tsis muaj plating, qhov, tawg thiab scum, ntau plating thickness, khawb, chromic acid stains, xeb dawb, thiab lwm yam. Cov qauv txawv teb chaws tsis meej heev. hais txog cov tsos mob tshwj xeeb.Qee qhov tsis xws luag yuav tsum tau teev nyob rau hauv daim ntawv cog lus thaum xaj.
