Yuav Ua Li Casyog cov yeeb nkab galvanized ua los ntawm?
1. Kub dip galvanized steel yeeb nkab qauv: kub dip galvanized yeeb nkab yog ua kom lub molten hlau nti nrog hlau matrix los ua alloy txheej, kom cov matrix thiab txheej ua ke. Txhawm rau kom tshem tawm cov hlau oxide nyob saum npoo ntawm cov yeeb nkab steel, kub-dip galvanized yeeb nkab yog ntxuav los ntawm ammonium chloride lossis zinc chloride aqueous tov los yog cov kua roj tov sib xyaw ntawm ammonium chloride thiab zinc chloride, thiab tom qab ntawd xa mus rau qhov kub-dip galvanizing tank. Kub dip galvanizing muaj qhov zoo ntawm cov khaub ncaws tsis zoo, muaj zog adhesion thiab kev pab lub neej ntev. Lub cev ua kom lub cev thiab tshuaj lom neeg nyob nruab nrab ntawm cov txheej nruab nrog kub-dip galvanized steel yeeb nkab thiab molten da dej ua rau kev tsim cov zinc ferroalloy txheej nrog lub txheej txheem ua hauj corrosion. Cov alloy txheej yog ua ke nrog ntshiab zinc txheej thiab steel yeeb nkab matrix. Yog li ntawd, nws txoj kev txhim kho corrosion yog qhov muaj zog.
2. Uantej-galvanizedhlaucov qauv yeeb nkab: galvanized sawb yeeb nkab tau hloov kho cov txheej txheem ntau lawm ntawm kub dip galvanized yeeb nkab. Ua ntej, txoj hlua steel siv rau kev ua cov yeeb nkab yog pickled. Txhawm rau tshem tawm cov hlau oxide nyob rau saum npoo ntawm cov txaij steel, nws tau ntxuav los ntawm ammonium chloride lossis zinc chloride aqueous tov los yog cov kua roj sib xyaw ntawm ammonium chloride thiab zinc chloride, thiab tom qab ntawd xa mus rau lub thawv dej kub galvanizing. Tom qab ntawd huab cua qhuav thiab ua ayeeb nkabCov. Cov txheej yog sib txawv thiab ci, thiab tus nqi ntawm cov plating zinc yog me me, uas yog qis dua tus nqi ntawm kev ua cov kub-dip galvanized yeeb nkab. Nws qhov kev txhim kho corrosion yog me ntsis zuj zus dua li qhov ntawm cov kub-dip galvanized yeeb nkab.
