Kub-dip galvanized kav thiab pre-galvanized kav yog ob hom galvanized kav feem ntau siv hauv kev tsim kho thiab kev lag luam. Txawm hais tias lawv zoo ib yam, lawv muaj qee qhov sib txawv tseem ceeb uas cov neeg yuav khoom thiab cov neeg tsim khoom yuav tsum coj mus rau hauv tus account.
Kub-dip Galvanized Pipes
Kub-dip galvanization entails dipping cov yeeb nkab steel rau hauv ib da dej ntawm zinc ntawm qhov kub ntawm ib ncig ntawm 450 degree. Cov txheej txheem no tsim cov txheej tuab ntawm zinc txheej rau ntawm qhov chaw ntawm cov yeeb nkab steel, uas muaj kev tiv thaiv ntev los ntawm corrosion thiab xeb. Cov txheej txheem yog nrov vim nws lav ib qho kev sib tw thiab ruaj khov uas tuaj yeem kav ntev txog 50 xyoo.
Pre-galvanized yeeb nkab
Pre-galvanization cuam tshuam me me electrolysis ntawm steel kav thiab ces dipping lawv nyob rau hauv ib tug molten zinc tov. Nws coats saum npoo ntawm cov kav hlau steel nrog ib txheej nyias ntawm zinc uas muab kev tiv thaiv tsawg dua ntawm xeb thiab corrosion. Cov txheej txheem yog siv sij hawm tsawg thiab tsis tshua kim. Cov kav dej uas dhau los ntawm cov txheej txheem no yog qhov zoo tagnrho rau kev siv sab hauv tsev lossis thaj chaw uas tsis tshua muaj corrosion.
Sib piv Kub-dip Galvanized thiab Pre-galvanized kav
Thawj qhov sib txawv ntawm cov kav dej kub-dip thiab pre-galvanized yog cov tuab ntawm zinc txheej ntawm cov kav hlau. Cov kav dej kub-dip galvanized muaj cov zinc txheej uas muaj zog dua, ua rau lawv kim dua li cov kav dej ua ntej galvanized. Txawm li cas los xij, lawv muaj kev ruaj ntseg tiv thaiv xeb thiab lwm yam corrosion, ua rau lawv zoo tagnrho rau kev siv sab nraum zoov, tshwj xeeb tshaj yog nyob rau hauv kev lag luam thiab hnyav ib puag ncig.
Hauv qhov sib piv, cov kav dej ua ntej galvanized yog nyias, muaj cov txheej txheem ntau dua li cov kav dej kub, thiab, yog li ntawd, pheej yig dua. Lawv zoo meej rau kev siv sab hauv tsev lossis thaj chaw uas tsis tshua muaj kev phom sij rau ib puag ncig.
Xaus
Hauv cov ntsiab lus, kev xaiv ntawm cov kav dej kub-dip thiab pre-galvanized kav yuav nyob ntawm daim ntawv thov, lub neej yuav tsum tau muaj, ib puag ncig raug, thiab pob nyiaj siv. Cov kav dej kub-dip galvanized tiv thaiv cov kav hlau zoo los ntawm xeb thiab xeb, ua rau lawv zoo tagnrho rau kev siv sab nraum zoov thiab kev lag luam. Xwb, cov kav dej ua ntej galvanized zoo dua rau kev siv sab hauv tsev lossis thaj chaw uas tsis tshua muaj kev phom sij rau ib puag ncig.
