Galvanized Steel Chev Sheet
Galvanized Steel Chev yog tsim los ntawm immersing ib daim hlau nyias hauv lub molten zinc da dej kom ib txheej ntawm zinc adheres rau saum npoo. Raws li cov khoom siv hauv tsev nrog tus nqi tseem ceeb, galvanized steel phaj tau siv dav hauv kev tsim kho niaj hnub no.
Galvanized steel phaj coils yog tsim los ntawm cov txheej txheem txuas ntxiv galvanizing, uas yog, cov dov steel panels tau txuas ntxiv mus rau hauv lub plating da dej uas muaj zinc molten los ua galvanized steel panels. Cov phaj hlau no kuj yog ua los ntawm cov txheej txheem kub dip, tab sis nws yog rhuab mus txog 500℃tam sim ntawd tom qab tawm hauv lub tank los tsim cov yeeb yaj kiab ntawm zinc thiab hlau.
Hom galvanized coil no muaj cov xim zoo adhesion thiab weldability.Galvanized daim hlau tuaj yeem siv los ua galvanized puag daim hlau rau xim coated galvanized steel coils.

Cov yam ntxwv saum npoo
Spangle: Qhov saum npoo ntawm cov tsoos kub-dip galvanized coils feem ntau pom cov zinc siv lead ua qauv (spangle), tsim los ntawm kev sib zog thiab crystallization ntawm zinc molten, uas muab cov nyhuv zoo nkauj. Txawm li cas los xij, cov txheej txheem niaj hnub no kuj tau tsim ua tiav nrog qhov me me spangle thiab tsis muaj spangle (smoothing) kom tau raws li ntau yam kev xav tau (piv txwv li, yuav tsum tau ua kom du nto rau kev pleev xim tom ntej).
Kev Kho Hniav: Tom qab-galvanizing kev kho mob xws li passivation, oiling, thiab phosphating tuaj yeem txhim kho corrosion kuj, txhim kho xim, lossis muab luv luv - tiv thaiv xeb.
