(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 txuas nws lub neej kev pab cuam. Cov kev tshawb fawb tau pom tias kub-dip galvanized zinc coatings tuab dua 3 millimeters tuaj yeem siv tau rau 5-7 xyoo, thaum cov nce mus txog 7-10 millimeters tuaj yeem kav ntev dua 15 xyoo.
Kev sib piv: Piv rau cov galvanizing txias, kub-dip galvanizing yuav tsis muaj qhov zoo dua hauv cov tuab (qhov tuab ntawm cov galvanizing txias yog nyob nruab nrab ntawm 40 micrometers txog 120 micrometers). Txawm li cas los xij, kub-dip galvanizing muab lub zog adhesion thiab corrosion kuj los ntawm kev tsim cov hlau-zinc alloy txheej.
(2) Environmental Factors
Ib puag ncig sib txawv: Lub neej ntev ntawm kub-dip galvanized coatings txawv nyob ntawm qhov chaw. Hauv kev lag luam, nroog, thiab ntug dej hiav txwv, vim muaj cov xwm txheej xws li cov pa phem hauv huab cua, kev lag luam emissions, thiab seawater corrosion, lub neej ntawm kub-dip galvanized txheej tuaj yeem ncav cuag 15-20 xyoo. Hauv thaj chaw nyob deb nroog lossis roob roob, qhov twg cov xwm txheej no tsis tshua muaj tshwm sim, lub neej ntawm cov txheej kub-dip galvanized tuaj yeem 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 qhov ua rau puas tsuaj, ua rau corrosion thiab degradation, yog li shortening nws cov kev pab cuam lub neej.
(3) Khoom zoo thiab txheej txheem
Cov Khoom Siv Zoo: Cov khoom siv zoo kub-dip galvanized feem ntau yog siv cov hlau zoo thiab ua tiav cov txheej txheem ntau lawm thiab kev tswj kom zoo. Cov khoom no muaj qhov sib xws thiab tuab zinc txheej uas zoo dua tiv thaiv corrosion thiab oxidation.
Cov txheej txheem ntau lawm: 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 galvanized txheej, uas nyob rau hauv lem cuam tshuam nws lub neej kev pab cuam.
(4) Kev tu
Kev tu tsis tu ncua: Kev saib xyuas tsis tu ncua ntawm cov khoom kub-dip galvanized kuj yog ib qho tseem ceeb hauv kev tswj lawv lub neej. Kev tshuaj xyuas thiab tu cov av tsis tu ncua, cov dej tsub zuj zuj, thiab cov khib nyiab ntawm cov zinc txheej, thiab tam sim ntawd daws qhov kev puas tsuaj, tuaj yeem tiv thaiv corrosion thiab degradation ntxiv.
