Daim ntawv thov ntawm peb Galvanized Steel Coils:
1.Kev tsim kho thiab lub tsev: vov tsev; qhov cua tshuab; tes tuav; muab faib vaj huam sib luag, thiab lwm yam.
2.Kev ua haujlwm ntxiv: txheej txheej phaj.
3. Cov khoom siv hluav taws xob: tub yees; tshuab ntxhua khaub ncaws; lub kaw lus; microwave, thiab lwm yam.
Cov txheej txheem kub dip suav nrog hla cov hlau los ntawm cov zinc da dej, thiab cov txheej txheem electro galvanizing suav nrog kev siv zinc los ntawm kev kho electrolytic. Yog li ntawd, zinc txheej yog ruaj khov rau hauv lub hauv paus hlau los ntawm cov hlau-zinc bonding txheej. Peb cov khoom kub-dip galvanized yog tsim raws li specifications, thiab peb cov khoom electro-galvanized ua raws li cov specifications.
Galvanizing yog ib txoj hauv kev zoo tshaj plaws thiab kev siv nyiaj txiag los tiv thaiv cov hlau tsis muaj zog los ntawm qhov chaw corrosive. Zinc tsis yog tsuas yog ib qho kev thaiv ntawm cov hlau thiab ib puag ncig, tab sis kuj txi nws tus kheej los tiv thaiv cov hlau phaj hauv qab no. Thaum ob qhov sib txawv ntawm cov hlau sib txuas thiab txuas nrog dej thiab oxygen, kev txi lossis kev tiv thaiv tam sim no tshwm sim. Zinc nyiam corrodes hlau hauv hlau. Qhov kev tiv thaiv no tiv thaiv corrosion ntawm cov hlau hauv thaj chaw uas tsis muaj zinc. Yog li ntawd, lub diffusion ntawm corrosion los ntawm txiav ntug, drilling qhov, thiab lwm yam
