DX52D + Z Galvanized Steel Sheet
Galvanized ntawvyog ib daim ntawv hlau uas tau txais kev kho tshwj xeeb uas muaj kub galvanizing. Yog li ntawd, cov hlau yog immersed nyob rau hauv ib tug zinc crucible, thiaj li hais tias cov nplooj ntawv yog tag nrho them nrog no hlau.
Nyob ntawm cov ntawv tshwj xeeb, qhov immersion tuaj yeem ua tiav hauv zinc- hlau alloy. Nyob rau hauv txhua rooj plaub, thaum nqa tawm kub, nws tag nrho adheres rau cov hlau, yog li hlau thiab da dej ua inseparable. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm zinc - hlau alloy, uas tiv thaiv chipping mus rau ntau dua.
Yog li ntawd, nws nthuav tawm ib daim ntawv sab hauv ntawm cov hlau uas ua rau lub thickness ntawm daim ntawv, tab sis kuj muaj zinc txheej uas muab nws tus yam ntxwv galvanization. Yog li, cov hlau muaj kev tiv thaiv tag nrho los ntawm kev sib cuag nrog cov neeg ua haujlwm sab nraud thiab atmospheric.
Nyob rau hauv txhua rooj plaub, nws muaj tib lub peev xwm los txiav, drilled thiab xuas nrig ntaus li lwm yam steel ntawv. Qhov sib txawv tseem ceeb yog qhov muaj cov txheej txheem hlau tshiab uas ua los tiv thaiv lub cev steel.
