Galvanized Sheet Coil
Galvanizing Steel coil yog ib daim ntawv nyias nyias dipped rau hauv lub molten zinc tank kom nws nto adhere rau ib txheej ntawm zinc.Lub ntsiab siv ntawm nruam galvanized txheej txheem ntau lawm, uas yog, yob ntawm steel phaj nruam poob rau hauv lub melting zinc plating tank ua los ntawm galvanized hlau.
Galvanized coil muaj cov yam ntxwv ntawm kev tiv thaiv corrosion thiab zoo nto, thiab yog dav siv hauv kev tsim kho, khoom siv hauv tsev, tsheb, ntim khoom, tsheb thauj mus los thiab lwm yam haujlwm.
Zinc tawg yog ib qho chaw zoo nkauj ntawm cov ntawv kub kub -dip galvanized ntawv thiab coil, uas tshwm sim thaum cov hlau sawb yog coated nrog cov kua zinc tom qab dhau los ntawm zinc yias, thiab zinc grain nucleation tom qab loj hlob thaum lub ntuj solidification ntawm zinc txheej.
Zinc Bloom tiam yog cuam tshuam los ntawm qhov muaj pes tsawg leeg ntawm txheej thiab qhov cua txias / txoj kev. Thaum kub-dip galvanized sheet cov khoom tau tshwm sim thawj zaug, steel mills tsis tuaj yeem tswj qhov loj ntawm lub paj raws li lawv xav tau, thiab qhov chaw ntawm cov khoom kub kub-dip galvanized ntshiab zinc coils muaj ntau qhov ntau thiab tsawg thiab cov duab ntawm zinc paj, uas nyob rau hauv ib lub sij hawm coj mus rau kev ntseeg tias "tsuas yog cov zinc paj yog kub-dip galvanized".
Raws li kev tsim cov hlau tau txhim kho, cov txheej txheem ntawm kub -dip galvanizing ntawm cov ntawv nyias tam sim no tso cai rau kev tswj hwm ntawm kev tsim cov zinc paj, uas yog txhais los ntawm cov qauv thoob ntiaj teb loj hauv kev quab yuam.

Galvanized Steel Sheettxhais tau tias yog cov ntawv carbon steel coated nrog zinc ntawm ob sab. Galvanized Steel Chev Importer tsim galvanized steel nrog ob txheej txheem tseem ceeb: nruam kub dip galvanizing thiab electrogalvanizing.
Cov txheej txheem kub dip suav nrog hla cov hlau los ntawm cov zinc da dej, thiab cov txheej txheem electrogalvanizing suav nrog kev siv zinc los ntawm kev kho electrolytic. Yog li ntawd, zinc txheej yog ruaj khov rau hauv lub hauv paus hlau los ntawm cov hlau -zinc bonding txheej. Peb cov khoom kub-dip galvanized yog tsim raws li cov lus qhia tshwj xeeb, thiab peb cov khoom siv electro-galvanized ua raws li cov lus qhia tshwj xeeb.
Galvanizing yog ib txoj hauv kev zoo tshaj plaws thiab kev lag luam rau kev tiv thaiv liab qab steel los ntawm corrosive ib puag ncig. Zinc tsis yog tsuas yog ib qho kev thaiv ntawm cov hlau thiab ib puag ncig, tab sis kuj txi nws tus kheej los tiv thaiv cov hlau phaj hauv qab no. Thaum ob qhov sib txawv ntawm cov hlau sib txuas thiab txuas nrog dej thiab oxygen, kev txi lossis kev tiv thaiv tam sim no tshwm sim. Zinc nyiam corrodes hlau hauv hlau. Qhov kev tiv thaiv no tiv thaiv corrosion ntawm cov hlau hauv cov cheeb tsam uas tsis muaj zinc. Yog li ntawd, qhov diffusion ntawm corrosion los ntawm txiav ntug, drilling qhov, thiab lwm yam yog minimized.
