CS-B Galvanized Rolled Steel Chev

Galvanized ntawv yog hais txog steel phaj coated nrog ib txheej ntawm zinc. Galvanizing yog ib qho kev siv nyiaj txiag thiab kev tiv thaiv zoo uas feem ntau siv. Kwv yees li ib nrab ntawm lub ntiaj teb zinc ntau lawm yog siv rau hauv cov txheej txheem no.
Galvanized steel ntawv yog los tiv thaiv corrosion ntawm cov phaj steel thiab ua kom nws lub neej ua haujlwm ntev. Ib txheej ntawm cov hlau zinc yog coated rau saum npoo ntawm cov hlau phaj, uas yog hu ua galvanized steel phaj.

Galvanized Steel Coils tau dhau los ntawm cov txheej txheem tshuaj lom neeg kom tsis txhob corroding.Lub steel tau coated nyob rau hauv cov khaubncaws sab nraud povtseg ntawm zinc vim xeb yuav tsis tawm tsam no tiv thaiv hlau.Rau suav tsis tau rau sab nraum zoov, marine, los yog industrial daim ntaub ntawv, galvanized steel yog ib qho tseem ceeb fabrication tivthaiv. Cov txheej txheem tseem ceeb ntawm kev ua steel tiv thaiv corrosion yog los ntawm alloying nrog lwm cov hlau, zinc.Thaum hlau yog submerged nyob rau hauv melted zinc, cov tshuaj tiv thaiv mus tas li bonds zinc rau cov hlau los ntawm galvanizing.Yog li ntawd, zinc tsis yog raws nraim ib tug sealer. , zoo li cov xim, vim tias nws tsis yog lub tsho hlau xwb; nws ua tau mus tas li los ua ib feem ntawm nws.

Kub-dip galvanization yog ib daim ntawv ntawm galvanization.Nws yog txheej txheem ntawm txheej hlau thiab hlau nrog zinc, uas alloys nrog rau saum npoo ntawm lub hauv paus hlau thaum immersing cov hlau nyob rau hauv ib da dej ntawm molten zinc ntawm ib tug kub ntawm ib ncig ntawm 840 ° F ( 449 ° C).Thaum raug rau cov huab cua, cov zinc ntshiab (Zn) reacts nrog oxygen (O2) los ua zinc oxide (ZnO), uas ntxiv reacts nrog carbon dioxide (CO2) los ua zinc carbonate (ZnCO3), feem ntau npub grey, cov khoom siv muaj zog uas tiv thaiv cov hlau hauv qab los ntawm kev xeb ntxiv hauv ntau qhov xwm txheej.Galvanized steel yog dav siv hauv cov ntawv thov uas xav tau corrosion tsis muaj nqi ntawm cov hlau tsis muaj nqi, thiab suav hais tias zoo tshaj ntawm cov nqi thiab lub neej voj voog. Nws tuaj yeem raug txheeb xyuas los ntawm crystallization qauv ntawm qhov chaw (feem ntau hu ua "spangle").
