Yog vim li cas vim li cas cov khoom zoo ntawm qhuav kub-dip galvanized zinc yog zoo dua li ntub kub-dip galvanized zinc

Thaum lub sij hawm "qhuav" kub-dip galvanizing cov txheej txheem, txhuas tuaj yeem muab ntxiv rau hauv Molten zinc-zinc alloy txheej, tshwm sim nyob rau hauv lub ci ntsa iab zinc txheej thiab cov khoom lag luam zoo. Nyob rau tib lub sijhawm, thaum lub sijhawm kub-dip galvanizing, cov kuab tshuaj tau coated rau ntawm cov leeg hlau, thiab zinc chloride nyob rau hauv cov kuab yas tau pib me ntsis nrog cov hlau substrate. Raws li cov raj steel yog rhaub thaum ziab, cov tshuaj tiv thaiv nrawm dua. Yog li ntawd, ib zaug cov raj txheem hlau yog raus hauv Molirected nyob rau hauv Molren Dinten ntawm cov hlau thiab zinc los ntawm daim ntawv thov rau kev siv cov kev ntsuas hauv zinc. Qhov no ua rau nws nyuaj rau kev ploj lawm galvanization tshwm sim. Txawm li cas los xij, cov "ntub" kub-dip galvanizing cov txheej txheem tsis muaj cov xwm txheej zoo no. Ua ntej, txhuas tsis tuaj yeem muab ntxiv rau Molten Zinc nto. Txawm hais tias aluminium ntxiv, nws yuav tshwm sim nrog chloride hnyav los ua cov chloride aluminium thiab volator. Nyob rau tib lub sijhawm, hauv "ntub" kub-dip galvanizing tsuas yog pib kom tiv thaiv nyias ntawm Molten Zinc Nto thaum nws tsis yog zinc. Yog li ntawd, lub sijhawm thov cov flux yog luv heev, thiab tshuaj ntxuav tshuaj ntxuav tau tsis muaj zog. Kev ua kom rov ua haujlwm ntawm cov raj steel sab yog tsis txaus, uas cuam tshuam cov tshuaj tiv thaiv hlau-zinc tsis zoo, ua rau nws tsis txaus siab rau cov galvanization.
