Dab tsi yog qhov chaw ntawm cov khoom siv alloy hauv lub lauj kaub galvanizing?

Lub hauv paus ntawm ntau yam alloys nyob rau hauv molten zinc tuaj yeem faib dav rau hauv peb hom: Ua ntej, qhov tsis muaj kev cuam tshuam hauv kev lag luam zinc lossis remelted zinc, xws li txhuas, hlau, cadmium, tooj liab, arsenic, antimony, tin, thiab lwm yam. Qhov thib ob, kev txhob txwm tshaj tawm ntawm qee cov ntsiab lus alloy rau cov zinc molten rau lub hom phiaj tshwj xeeb. Piv txwv li, ntxiv cov nqi sib txawv ntawm txhuas los hloov qhov chaw tiav lossis microstructure ntawm galvanized zinc txheej. Thirdly, unavoidable impurities. Cov no suav nrog lwm cov impurities thiab cov kab mob tsis tuaj yeem nkag mus rau hauv lub lauj kaub galvanizing thaum lub sij hawm txheej txheem ntawm remelting zinc los yog ntxuav cov zinc scraps hauv av.
