Galvanized steel coil kev ua haujlwm tuaj yeem sib txawv raws li cov kev xav tau tshwj xeeb thiab kev siv, hauv qab no yog ib qho piv txwv ntawm kev ua haujlwm ntau:
Kev npaj cov khoom siv: Xaiv cov khaub thuas dov los yog kub dov steel coils ntawm qhov tsim nyog specifications thiab zoo raws li cov khoom siv hauv paus kom paub meej tias qhov chaw huv si.
Pickling thiab degreasing:
Lub steel kauj yog dipped nyob rau hauv ib tug acidic tov rau pickling kom tshem tawm oxides thiab impurities ntawm qhov chaw. Tom qab ntawd, kev kho degreasing tuaj yeem ua tiav los xyuas kom meej tias qhov chaw tsis muaj roj stains.
Ntxuav dej thiab pickling neutralization:
cov steel coils yog ntxuav nrog dej kom tshem tawm cov kua qaub seem thiab neutralized los kho tus nqi pH ntawm qhov chaw.
Pretreatment txheej:
Txheej txheej ntawm pretreatment tus neeg saib xyuas nyob rau saum npoo ntawm cov hlau kauj, feem ntau yog zinc oxide tov los yog lwm yam anti-corrosion agents, kom cov adhesion thiab uniformity ntawm galvanized txheej.
Kub-dip galvanizing:
Lub pre-kho steel kauj yog dipped nyob rau hauv molten zinc los ntawm cov txheej txheem kub-dip galvanizing. Cov hlau kauj yog immersed nyob rau hauv molten zinc rau ib lub sij hawm ntawm lub sij hawm, yog li ntawd cov zinc reacts nrog cov hlau nto los ua ib tug zinc-hlau alloy txheej.
Txias thiab kho:
Tom qab galvanizing, cov hlau kauj yog txias thiab kho kom khov thiab ruaj khov ntawm zinc-hlau alloy txheej thiab khi nws ruaj khov rau cov hlau substrate.
Flatning thiab trimming:
flattening thiab trimming ntawm galvanized steel coils los xyuas kom meej tias qhov loj thiab flatness ntawm steel coils ua tau raws li qhov yuav tsum tau ua.
Kev tshuaj xyuas thiab kev tswj kom zoo:
Kev tshuaj ntsuam xyuas, kev ntsuas thickness, galvanized txheej kev soj ntsuam zoo, thiab lwm yam yog ua los ntawm galvanized steel coils los xyuas kom meej tias cov khoom ua tau raws li cov qauv thiab cov kev cai.
Txiav thiab coiling:
Raws li cov neeg siv khoom xav tau, cov galvanized steel coils raug txiav rau hauv qhov tsim nyog thiab ntev, los yog coiled rau hauv coils rau khoom.
Ntim thiab shipping:
Ntim cov txheej txheem galvanized steel coils, thiab siv cov kev tiv thaiv tsim nyog, xws li kev ntim khoom thiab lub thawv, kom ntseeg tau tias cov khoom tsis puas thaum lub sijhawm thauj mus los.
Nws yuav tsum raug sau tseg tias cov kauj ruam tshwj xeeb thiab cov kab ke hauv kev ua haujlwm yuav sib txawv vim cov tuam ntxhab sib txawv thiab cov khoom yuav tsum tau ua. Txhua qhov txuas hauv cov txheej txheem ua tiav yuav tsum tau tswj nruj nruj thiab ua raws li cov qauv tsim los xyuas kom meej qhov zoo ntawm galvanized steel coils
