Qhov cuam tshuam ntawm Magnesium hauv Molten Zinc ntawm Kub-Dip Galvanizing

Magnesium (Mg) yog silvery-dawb nyob rau hauv cov xim thiab belongs rau hexagonal crystal system, nrog ib tug txheeb ze atomic mass ntawm 24.32, ib tug melting point ntawm 65 0 degree, thiab ib tug boiling point ntawm 112 0 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% thiab 0.084%. Txawm li cas los xij, thaum cov ntsiab lus magnesium nce mus txog 0.3-0.5%, nws ua rau cov txheej galvanized ua tuab thiab rougher, hloov nws cov tsos mus rau xim dawb thiab ua rau nws nkig, thaum tseem ua rau nws cov adhesion tsis zoo. Thaum cov ntsiab lus magnesium ntau tshaj 0.6%, galvanized txheej yuav thinner dua. Qhov sib ntxiv ntawm magnesium ua rau muaj kev cuam tshuam nruab nrab thaum lub sij hawm oxidation ntawm zinc, thawj zaug ua magnesium oxide, uas hloov oxygen mus rau zinc yooj yim dua yog zinc coj oxygen ncaj qha los ntawm huab cua. Feem ntau, magnesium tsis ntxiv thaum tsim cov kav dej galvanized rau cov dej thiab roj xa mus, tshwj tsis yog tias muaj xwm txheej tshwj xeeb.
