(1) Thickness Factor
Thickness Range: Lub thickness ntawm kub-dip galvanized zinc txheej ncaj qha cuam tshuam rau lawv lub neej. Feem ntau, tswj cov zinc txheej thickness nyob rau hauv qhov ntau ntawm 7-10 millimeters ua kom zoo corrosion kuj, yog li ncua lub neej kev pab cuam. Cov kev tshawb fawb tau pom tias cov txheej kub-dip galvanized tuab dua 3 millimeters tuaj yeem siv tau rau 5-7 xyoo, thaum cov nce mus txog 7-10 millimeters tuaj yeem tiv taus kev siv ntau dua 15 xyoo.
Kev sib piv: Muab piv rau cov galvanizing txias, kub-dip galvanizing yuav tsis muaj qhov zoo ntawm cov tuab (qhov tuab ntawm cov galvanizing txias yog nyob nruab nrab ntawm 40 micrometers mus rau 120 micrometers). Txawm li cas los xij, kub-dip galvanizing muab kev sib raug zoo zog thiab kev tiv thaiv corrosion los ntawm kev tsim cov hlau-zinc alloy txheej.
(2) Environmental Factors
Varying Environments: Lub neej ntev ntawm kub-dip galvanized coatings txawv nyob ntawm qhov chaw. Hauv kev lag luam, nroog, thiab chaw ntug hiav txwv dej, yam xws li huab cua phem, kev lag luam emissions, thiab seawater corrosion tuaj yeem cuam tshuam rau lub neej, feem ntau kav ntev 15-20 xyoo. Nyob rau hauv sib piv, nyob rau hauv cov cheeb tsam nyob deb nroog los yog roob roob uas tej yam tseem ceeb tsis tshua muaj, kub-dip galvanized txheej yuav kav ntev tshaj 30 xyoo.
Humidity thiab Corrosion: Hauv qhov chaw ntub dej, cov av noo siab, lossis qhov chaw muaj corrosive heev, zinc txheej ntawm kub-dip galvanized txheej yog ua rau kev puas tsuaj, ua rau corrosion thiab deterioration, yog li shortening lawv lifespan.
(3) Khoom zoo thiab txheej txheem
Cov Khoom Siv Zoo: Cov khoom siv zoo kub-dip galvanized feem ntau siv cov hlau zoo thiab ua tiav cov txheej txheem ntau lawm thiab kev tswj kom zoo. Cov khoom no muaj cov xim zoo nkauj thiab tuab zinc txheej uas zoo dua tiv thaiv corrosion thiab oxidation.
Txheej Txheem: Kev tsim cov txheej txheem kub-dip galvanizing suav nrog ntau cov kauj ruam xws li degreasing, pickling, dipping hauv flux, ziab thiab preheating, kub-dip galvanizing, thiab txias. Kev tswj nruj ntawm txhua kauj ruam ua kom zoo thiab adhesion ntawm zinc txheej, uas nyob rau hauv lem cuam tshuam nws lifespan.
(4) Kev tu
Kev tu tsis tu ncua: Kev saib xyuas tsis tu ncua thiab kev saib xyuas cov khoom kub-dip galvanized kuj tseem ceeb heev rau kev khaws lawv lub neej. Kev tshuaj xyuas thiab tu cov av tsis tu ncua, dej hauv pas dej, thiab cov khib nyiab ntawm cov zinc txheej, nrog rau kev kho sai sai, tuaj yeem tiv thaiv kev xeb thiab kev puas tsuaj ntxiv.
