Nkag siab Galvanized Steel Coils
Galvanized steel coils yog hlau nrog ib txheej ntawm zinc plated rau ntawm lawv qhov chaw los tiv thaiv corrosion. Cov txheej txheem no tsis tsuas yog txuas ntxiv lub neej kev pab cuam ntawm cov hlau, tab sis kuj txhim kho nws cov tsos. Vim lawv lub zog siab thiab ua haujlwm rau ib puag ncig corrosion, galvanized steel coils tau dav siv hauv kev lag luam xws li kev tsim kho, tsheb, thiab kev tsim khoom.
Zinc plating txheej txheem
Kub-dip galvanizing suav nrog ntau cov kauj ruam, txhua qhov tseem ceeb rau kev ua kom muaj txiaj ntsig ntawm zinc txheej. Feem ntau kub-dip galvanizing txoj kev rau steel coils suav nrog cov theem hauv qab no:
Kev kho saum npoo: Hlau yuav tsum tau ntxuav kom huv si ua ntej galvanizing kom tshem tawm cov kab mob xws li roj, roj, plua plav, thiab xeb. Qhov no feem ntau xav tau cov txheej txheem tu, suav nrog degreasing, pickling, thiab yaug. Kev kho saum npoo kom zoo yog qhov tseem ceeb vim tias txhua qhov impurities tuaj yeem ua rau tsis zoo adhesion ntawm zinc plating.
Kev kho fluorescence:Tom qab ntxuav, cov hlau coils yuav tsum tau kho nrog cov tshuaj flux, feem ntau yog tsim los ntawm zinc ammonium chloride. Cov kauj ruam no pab tiv thaiv oxidation ntawm steel nto ua ntej immersion nyob rau hauv molten zinc. Lub flux kuj txhawb kev sib raug zoo ntawm zinc thiab hlau.
Kub-dip galvanizing: Cov coil kho steel yog muab tso rau hauv lub molten zinc da dej, feem ntau ua kom sov li ntawm 450℃(842℃F). Thaum lub sijhawm txheej txheem no, cov tshuaj tiv thaiv metallurgical tshwm sim, tsim zinc- hlau alloy txheej ntawm cov hlau. Cov txheej txheej no yog qhov tseem ceeb rau kev tiv thaiv corrosion ntawm galvanized steel kauj.
Txias thiab tshuaj xyuas:Tom qab cov hlau coils raug tshem tawm ntawm lub da dej galvanizing, lawv tau txias kom cia cov zinc txheej kom khov. Cov galvanized steel coils tom qab ntawd tau txais kev tshuaj xyuas zoo kom ntseeg tau tias cov txheej txheem tsis sib xws thiab ua tau raws li cov qauv kev lag luam. Txhua qhov tsis xws lossis tsis sib xws tuaj yeem daws tau ntawm theem no.
Tom qab -kev kho mob:Qee zaum, kev kho mob ntxiv yuav tsum tau txhim kho kev ua haujlwm ntawm galvanized steel coils. Cov kev kho mob no muaj xws li passivation (uas muab ib txheej ntxiv ntawm kev tiv thaiv corrosion) los yog pleev xim rau (rau kev zoo nkauj).
Qhov zoo ntawm galvanized steel coils
Kub-dip galvanizing tuaj yeem txhim kho kev ua haujlwm ntawm steel coils, nqa ntau yam txiaj ntsig:
Corrosion Resistance: Ib qho txiaj ntsig tseem ceeb ntawm galvanized steel coils yog lawv cov corrosion kuj zoo heev. Cov txheej zinc ua raws li kev thaiv, tiv thaiv cov hlau hauv qab ntawm cov dej noo thiab ib puag ncig.
Durability: Galvanized steel coils muaj lub neej ua haujlwm ntev dua li cov hlau tsis kho, ua rau lawv xaiv kev lag luam rau ntau yam kev siv.
Cov nqi kho mob qis:Vim tias galvanized steel coils yog corrosion- tiv taus, lawv yuav tsum tau saib xyuas me ntsis, yog li txo cov nqi ntev - rau cov lag luam.
Kev siv ntau yam: Galvanized steel coils tuaj yeem siv rau hauv ntau yam kev siv, los ntawm cov vov tsev thiab phab ntsa vaj huam sib luag rau cov khoom siv tsheb thiab cov khoom siv.
nyob rau hauv xaus
Cov txheej txheem galvanizing ntawm galvanized steel coils yog ib kauj ruam tseem ceeb hauv kev txhim kho cov khoom ruaj khov thiab corrosion kuj. Los ntawm kev nkag siab txhua kauj ruam ntawm cov txheej txheem no, kev lag luam tuaj yeem nkag siab zoo dua tus nqi ntawm galvanized steel coils hauv lawv daim ntawv thov. Nrog kev txhim kho thev naus laus zis, cov txheej txheem galvanizing thiab cov ntaub ntawv tau hloov zuj zus mus tas li, kom ntseeg tau tias cov hlau galvanized tseem yog qhov kev xaiv txhim khu kev qha rau yav tom ntej.
