Vim li cas ho kub-dip galvanizing siv rau qhov chaw ntawm cov khoom steel?

Hlau yog nquag xeb thiab txawm tias ua tiav kev puas tsuaj thaum raug huab cua, dej, lossis av. Kwv yees li ib feem kaum ntawm tag nrho cov hlau ntau lawm txhua xyoo vim yog corrosion. Yog li ntawd, kev tiv thaiv txheej los yog platings yog tsim nyog los tiv thaiv hlau los ntawm corrosion. Kub-dip galvanizing yog ib txoj kev zoo li no. Zinc tiv taus cov kev hloov pauv hauv huab cua qhuav, thiab hauv huab cua ntub, nws tsim cov txheej txheem ntom ntom ntawm zinc carbonate ntawm nws qhov chaw, uas tiv thaiv cov zinc hauv qab los ntawm kev xeb ntxiv. Tsis tas li ntawd, yog tias cov txheej galvanized puas vim qee yam, nthuav tawm thaj tsam me me ntawm cov hlau substrate, micro-galvanic cell forms ntawm zinc thiab steel substrate, ua rau cov hlau substrate cathode thiab yog li tiv thaiv. Tus nqi corrosion ntawm zinc nyob rau hauv huab cua yog ib feem kaum tsib ntawm cov hlau, qhia tias lub neej ntawm zinc tiv thaiv txheej yog ntev heev. Tsis tas li ntawd, piv rau lwm cov khoom siv hlau corrosion-resistant, zinc yog pheej yig. Yog li ntawd, kub-dip galvanizing steel yog ob qho tib si ruaj thiab nqi-zoo.
