Galvanized steel ntawv
Galvanized ntawv yog cov ntawv hlau uas tau txais ib qho kev kho mob tshwj xeeb uas muaj cov kub kub galvanizing kub. Xws li, cov hlau yog raus rau hauv qhov zinc crucible, yog li cov ntawv txheeb tau npog nrog cov hlau no.
Nyob ntawm daim ntawv tshwj xeeb, kev siv tau tej zaum yuav tau nqa tawm hauv qhov zinc {{}}}} hlau hlau. Nyob rau hauv txhua rooj plaub, thaum nqa tawm kub, nws tag nrho cov adheres rau cov hlau, yog li cov hlau thiab da dej los ua inseparable. Qhov no tshwj xeeb tshaj yog cov ntaub ntawv ntawm zinc {{}}} hlau hlau, uas tiv thaiv chipping mus rau ib qho ntau dua.
Yog li, nws nthuav tawm ib daim ntawv sab hauv ntawm cov hlau uas suav nrog cov tuab ntawm daim ntawv, tab sis kuj yog cov txheej zinc uas muab nws uas cov xeeb ceem galvanization. Yog li, cov hlau tau txais kev tiv thaiv tag nrho los ntawm kev sib chwv nrog cov neeg sawv cev sab nraud thiab atmospheric.
Nyob rau hauv txhua rooj plaub, nws muaj tib lub peev xwm yuav raug txiav, drilled thiab punched ua lwm yam steel ntawv. Lub ntsiab sib txawv yog lub xub ntiag ntawm cov txheej txheem hlau tshiab uas ua los ua tus tiv thaiv rau lub cev hlau.
