3. Vim li cas cov khoom ntawm cov hlau ua hluav taws kub kub galvanized?

Cov hlau ua rau muaj kev cuam tshuam nrog kev xeb hauv huab cua, dej, lossis av, uas tuaj yeem ua kom tiav tsis zoo. Txhua xyoo, corrosion -} Cov hlau uas cuam tshuam ntsig txog tus account li ntawm ib feem kaum ntawm kev tsim tag nrho. Yog li, kev tiv thaiv txheej yog qhov tseem ceeb rau cov hlau los ntawm kev corrosion. Kub - dip galvanizing sawv ua cov tshuaj tseem ceeb. Zinc tseem ruaj khov nyob rau hauv cov huab cua qhuav tab sis ua ib tug dense alkaline zinc carbonate dawb paug, tiv thaiv kev tiv thaiv kev txhim kho sab hauv. Thaum lub galvanized txheej yog kev hloov kho thiab nthuav tawm steel thaj chaw muaj micro {{8} Enterchemical lub hlwb uas cov hlau ua raws li cathode. Zinc's Dinc's atmospheric dolosion tus nqi yog 1 / 15th tias ntawm cov hlau, qhia tau ntev ntev. Ntxiv mus, Zinc's tus nqi-} ua hauj lwm zoo piv rau lwm txoj kev corrosion- dip galvanizing ua cov tshuaj muaj txiaj ntsig thiab cov tshuaj daws tau.
