Yuav ua li casyog galvanized yeeb nkab ua los ntawm?
1. Kub dip galvanized steel yeeb nkab qauv: kub dip galvanized yeeb nkab yog ua kom cov hlau molten react nrog hlau matrix los tsim alloy txheej, kom cov matrix thiab txheej ua ke. Txhawm rau tshem tawm cov hlau oxide nyob rau saum npoo ntawm cov yeeb nkab steel, cov yeeb nkab kub-dip galvanized yog ntxuav los ntawm ammonium chloride los yog zinc chloride aqueous tov los yog tov tov tank ntawm ammonium chloride thiab zinc chloride, thiab ces xa mus rau kub-dip. galvanizing tank. Kub dip galvanizing muaj qhov zoo ntawm cov txheej txheej, muaj zog adhesion thiab lub neej ua haujlwm ntev. Lub complex lub cev thiab tshuaj tiv thaiv ntawm lub substrate ntawm kub-dip galvanized steel yeeb nkab thiab molten da dej ua rau tsim ib tug zinc ferroalloy txheej nrog ib tug compact corrosion kuj qauv. Cov txheej txheej alloy yog kev sib xyaw nrog cov zinc txheej ntshiab thiab cov yeeb nkab steel matrix. Yog li ntawd, nws cov corrosion kuj muaj zog.
2. Pre-galvanizedhlauyeeb nkab qauv: galvanized sawb yeeb nkab tau kho cov txheej txheem ntau lawm ntawm kub dip galvanized yeeb nkab. Ua ntej, steel sawb siv rau cov yeeb nkab ua yog pickled. Txhawm rau tshem tawm cov hlau oxide nyob rau saum npoo ntawm cov sawb hlau, nws yog ntxuav los ntawm ammonium chloride los yog zinc chloride aqueous tov los yog tov tov tank ntawm ammonium chloride thiab zinc chloride, thiab ces xa mus rau lub kub dip galvanizing tank. Tom qab ntawd cua qhuav thiab ua ib qhocev. Cov txheej txheej yog sib xws thiab ci, thiab cov nyiaj zinc plating yog me me, uas yog qis dua tus nqi ntawm kev tsim cov yeeb nkab kub-dip galvanized. Nws cov corrosion kuj yog me ntsis phem dua li ntawm kub-dip galvanized yeeb nkab.
