Galvanized coil yog cov khoom siv hlau uas muaj zinc txheej adhered rau saum npoo ntawm cov ntawv nyias nyias los ntawm cov txheej txheem galvanizing tas li; Nws cov khoom tseem ceeb yog hlau thiab zinc alloys. Nws yog dav categorized rau ob hom: tsis tu ncua galvanized steel los xij thiab alloyed galvanized steel los xij. Tuam Tshoj yog tus tsim khoom loj tshaj plaws hauv ntiaj teb ntawm kub-dip galvanized coils, tuav cov khoom tsim tawm txhua xyoo ntawm kwv yees li 90 lab tons. Galvanized sheets feem ntau yog siv hauv kev tsim kho kev lag luam, kev tsim khoom siv hauv tsev, kev tsim tsheb, thiab kev lag luam teeb.
Nrog rau kev lag luam nce ntxiv ntawm cov tsheb tshiab lub zog (NEVs), qhov kev thov rau cov nplooj ntawv galvanized nyob rau hauv cov sector no tau pom kev loj hlob, nrog rau nws feem ntawm tag nrho cov kev xav tau kwv yees mus txog 11.58% los ntawm Lub Kaum Hli 2025. Cov txheej txheem tsim khoom suav nrog immersing coiled steel nplooj ntawv rau hauv da dej ntawm zinc molten. Rau cov alloyed variants, cov khoom tau dhau los ntawm kev tshaj tawm - kev kho cua sov ntawm 500℃los tsim zinc- hlau alloy txheej, uas muaj qhov zoo tshaj plaws ntawm cov xim adhesion thiab weldability. Kev ua haujlwm ntau lawm suav nrog cov thev naus laus zis siab tshaj-xws li dross-skimming robots thiab zinc txheej thickness gauges- kom ntseeg tau tias cov khoom zoo sib xws.
Raws li cov yam ntxwv ntawm kev ua tau zoo, cov khoom no tau muab faib ua xya qib sib txawv, suav nrog cov kev siv dav dav, kev sib txuas ntawm cov tshuab, thiab cov ntawv thov sib sib zog nqus; lub hauv paus substrate feem ntau muaj cov txias-rolled coils los yog kub-rolled, acid-pickled coils. Hais txog cov txheej txheem txheej, cov ntawv galvanized tau muab faib ua plaub hom raws li lawv cov qauv "spangle": ib txwm spangle, minimized spangle, xoom spangle, thiab zinc- hlau alloy. Tsis tas li ntawd, cov lej tshwj xeeb-xws li ntawm Z60 txog Z600-raug xaiv los xaiv qhov hnyav ntawm zinc txheej siv rau ob sab ntawm daim ntawv.
