Galvanized kauj, dipping ib daim ntawv ntawm cov hlau mus rau hauv lub molten zinc da dej kom nws adheres rau ib daim ntawv ntawm zinc ntawm nws nto.Tam sim no, cov txheej txheem txuas ntxiv galvanizing yog tsuas yog siv rau kev tsim khoom, uas yog, cov phaj steel rau hauv ib lub yob ntawm nruam immersion nyob rau hauv lub melting ntawm zinc plating tank ua los ntawm galvanized steel phaj thiab alloyed galvanized steel ntawv.Cov phaj hlau no kuj yog ua los ntawm kub dip, tab sis tam sim ntawd tom qab lub trough, nws yog rhuab mus txog 500 ℃, thiaj li hais tias nws generates ib tug alloy zaj duab xis ntawm zinc thiab hlau.Qhov no galvanized coil muaj cov txheej txheem zoo adhesion thiab weldability.
Galvanized coil khoom
a) Kub dip galvanized steel kauj.Ib tug nyias steel kauj yog dipped rau hauv lub molten zinc tank kom nws nto yog adherent rau nyias steel kauj ntawm zinc.Tam sim no, cov txheej txheem txuas ntxiv galvanizing yog tsuas yog siv rau kev tsim khoom, uas yog, cov phaj steel rau hauv ib yob ntawm nruam immersion nyob rau hauv lub melting zinc plating tank ua los ntawm galvanized steel kauj;
b) alloyed galvanized steel kauj.Cov hlau kauj no kuj yog ua los ntawm kub leaching, tab sis tam sim ntawd tom qab lub trough, nws yog rhuab mus txog 500 ℃, thiaj li hais tias nws generates ib tug alloy zaj duab xis ntawm zinc thiab hlau.Qhov no galvanized kauj muaj zoo txheej nruj thiab weldability;
a) galvanized steel kauj.Hom galvanized steel kauj no muaj kev ua haujlwm zoo los ntawm electroplating.Tab sis cov txheej yog nyias, corrosion kuj zoo li kub dip galvanized kauj;
Kev siv ntawm galvanized coil
Ib tug loj tus naj npawb ntawm galvanized nyias coils yog siv nyob rau hauv tsheb tsim, tub yees, kev tsim kho, qhov cua thiab cua sov chaw thiab cov rooj tog tsim.Zinc plating tau dhau los ua ib txoj kev tseem ceeb ntawm kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv nruj heev, tab sis kuj yog zinc txheej puas, nws tseem tuaj yeem tiv thaiv cov corrosion ntawm hlau puag hlau los ntawm kev tiv thaiv cathodic.
Galvanized coil specification
Galvanized coil specifications yog cov galvanized ntawv tuab hauv 0.4 ~ 2.0.Feem ntau tsawg dua 0.4 hli lub xeev cov tuam txhab loj steel tsis tsim, feem ntau yog rau kev tsim cov hlau me me, cov lus qhia tshwj xeeb yog 0.35, 0.30, 0.28, 0.25, feem ntau yog thinest mus rau 0.15, ntau tshaj 2.0mm vim qhov nyuaj ntawm straightening, yog li ntau tshaj 2.0 nrog qhov nce ntawm thickness ntawm tus nqi kuj nce.
