Dab tsi yog qhov cuam tshuam ntawm magnesium hauv molten zinc ntawm kub-dip galvanizing?

Magnesium (Mg), uas muaj cov xim dawb-dawb thiab muaj nyob rau hauv hexagonal siv lead ua, muaj cov txheeb ze atomic loj ntawm 24.32, melting point ntawm 650 degree, thiab kub point ntawm 112{{8} } degree. Qhov sib ntxiv ntawm magnesium rau zinc txhim kho corrosion kuj, txawm nyob rau hauv ntau ntawm ob peb txhiab los yog kaum txhiab. Kev tiv thaiv corrosion yog qhov zoo tshaj plaws thaum cov ntsiab lus magnesium nyob nruab nrab ntawm 0.024-0.084%. Txawm li cas los xij, thaum cov ntsiab lus magnesium nce mus txog 0. Tab sis thaum cov ntsiab lus magnesium ntau tshaj 0.6%, galvanized txheej yuav thinner dua. Qhov sib ntxiv ntawm magnesium ua rau cov kev cuam tshuam nruab nrab thaum lub sij hawm oxidation txheej txheem ntawm zinc, thawj zaug tsim magnesium oxide, uas hloov oxygen mus rau zinc yooj yim dua yog zinc ncaj qha coj oxygen los ntawm huab cua. Feem ntau, magnesium tsis ntxiv rau hauv kev tsim cov kav dej galvanized rau cov dej thiab cov pa xa hluav taws xob, tshwj tsis yog siv rau lub sijhawm tshwj xeeb.
