Galvanized Steel Chev

Lus piav qhia luv luv:

Galvanized coil, Ib daim hlau nyias yog muab tso rau hauv lub plating tank uas muaj zinc molten kom ib txheej ntawm zinc adheres rau nws nto.Nws yog tsuas yog tsim los ntawm cov txheej txheem galvanizing tas li, uas yog, dov steel phaj yog txuas ntxiv mus rau hauv lub plating tank uas muaj zinc molten los ua galvanized steel phaj.Galvanized coils tuaj yeem muab faib ua cov kub dov galvanized coils thiab txias dov kub dov galvanized coils, uas yog siv hauv kev tsim kho, khoom siv hauv tsev, tsheb, ntim khoom, kev thauj mus los thiab kev lag luam hauv tsev.Hauv particular, steel qauv tsim, tsheb tsim, steel warehouse manufacturing thiab lwm yam lag luam.Qhov kev thov ntawm kev tsim kho kev lag luam thiab lub teeb kev lag luam yog lub lag luam tseem ceeb ntawm galvanized coil, uas suav txog li 30% ntawm qhov kev thov ntawm cov ntawv galvanized.

Galvanized Steel Coil Processing Technology

(1) Kub-dip galvanized steel ntawv.Ib daim hlau nyias yog immersed nyob rau hauv lub plating tank uas muaj zinc molten kom ib txheej ntawm zinc adheres rau nws nto.Nws yog tsuas yog tsim los ntawm cov txheej txheem galvanizing tas li, uas yog, dov steel phaj yog txuas ntxiv mus rau hauv lub plating tank uas muaj zinc molten los ua galvanized steel phaj.

(2) Alloyed galvanized steel ntawv.Hom hlau phaj no kuj yog tsim los ntawm txoj kev kub dip, tab sis nws yog rhuab mus txog 500°C tam sim ntawd tom qab tawm hauv lub tank los tsim cov yeeb yaj kiab alloy ntawm zinc thiab hlau.Qhov no galvanized phaj muaj zoo adhesion thiab weldability.

(3) Electro-galvanized steel phaj.Hom galvanized steel ntawv no tsim los ntawm txoj kev electroplating muaj kev ua tau zoo.Txawm li cas los xij, cov txheej yog nyias thiab nws cov kev tiv thaiv corrosion tsis zoo li cov ntawv kub-dip galvanized;

(4) Ib sab galvanized steel phaj thiab ob sab galvanized steel phaj.Ib sab galvanized steel ntawv yog ib yam khoom uas yog galvanized ntawm ib sab.Nyob rau hauv cov nqe lus ntawm vuam, painting, anti-xeb kho, ua, thiab lwm yam., nws muaj zoo adaptability tshaj ob-sided galvanized nplooj ntawv.Yuav kom kov yeej qhov tsis txaus ntawm ib sab tsis tau coated nrog zinc, muaj lwm hom galvanized ntawv uas yog coated nrog ib txheej nyias ntawm zinc rau sab nraud, uas yog, ob sab galvanized ntawv;

(5) Alloy thiab composite galvanized steel los xij.Nws yog ua los ntawm zinc thiab lwm yam hlau xws li txhuas, zinc alloy lossis txawm tias cov phaj sib xyaw plated.

Galvanized Steel Chev nta

1. Corrosion Resistance: Galvanizing yog ib qho kev siv nyiaj txiag thiab kev tiv thaiv xeb uas feem ntau siv.Txog ib nrab ntawm lub ntiaj teb zinc ntau lawm yog siv rau cov txheej txheem no.Zinc tsis tsuas yog tsim cov txheej tiv thaiv ntom ntom ntawm cov hlau, tab sis kuj muaj kev tiv thaiv cathodic.Thaum cov zinc txheej puas lawm, nws tseem tuaj yeem tiv thaiv corrosion ntawm cov khoom siv hlau los ntawm kev tiv thaiv cathodic.

2. Zoo Txias Khoov thiab Vuam Kev Ua Haujlwm: qis carbon steel feem ntau yog siv, uas yuav tsum tau ua kom txias txias, kev ua haujlwm vuam thiab qee yam kev ua haujlwm stamping.

3. Reflectivity: siab reflectivity, ua rau thermal barrier

4. Cov txheej txheem muaj zog toughness, thiab cov zinc txheej ua ib qho tshwj xeeb metallurgical qauv, uas tuaj yeem tiv taus kev puas tsuaj thaum lub sij hawm thauj mus los thiab siv.
