Qhov Kev Tiv Thaiv Corrosion ntawm Galvanized Hlau Zoo Li Cas?

Cov hlau galvanized (GI hlau xaim) paub zoo txog nws lub peev xwm tiv taus xeb. Nws siv dav hauv kev tsim kho, kev ua liaj ua teb, thiab kev lag luam ntim khoom thoob plaws ntiaj teb. Ntawm ntau hom hlau galvanized,kub dipped galvanized hlau xaimyog qhov ruaj khov tshaj plaws. Thiab txawm tias cov hlau nyias nyias los ntawm cov neeg muab khoom hlau Suav teb uas ntseeg tau kuj tuaj yeem ua tau zoo hauv kev tiv taus xeb.
Qhov laj thawj rau nws txoj kev tiv thaiv xeb zoo yog cov txheej txheem galvanization. Ib txheej zinc tsim ib qho kev thaiv lub cev tiv thaiv cov dej noo, oxygen, thiab cov tshuaj corrosive. Rau cov hlau hlau kub-dipped galvanized, cov txheej zinc tuab (feem ntau 85 - 120g / m²) tsis yog tsuas yog tiv thaiv cov hlau sab hauv tab sis kuj muab kev tiv thaiv cathodic. Zinc yuav corrode ua ntej es tsis txhob hlau, uas tuaj yeem ua rau cov hlau kav ntev dua. Hom hlau no zoo heev rau kev siv sab nraum zoov. Nws tuaj yeem sawv ntsug rau nag, av noo, thiab kev raug tshuaj lom neeg me me rau li 10 - 15 xyoo hauv cov xwm txheej ib txwm muaj.
Muaj ntau yam uas cuam tshuam rau nws qhov ruaj khov. Qhov tuab ntawm cov zinc txheej yog ib qho ntawm lawv. Cov txheej tuab dua txhais tau tias kev tiv thaiv ntev dua. Cov xwm txheej ib puag ncig kuj tseem ceeb. Hauv cov cheeb tsam ntug dej hiav txwv uas muaj ntsev tsuag, cov hlau yuav xav tau galvanization hnyav dua. Qhov zoo ntawm cov khoom los ntawm cov chaw tsim khoom hlau galvanized zoo kuj tseem ceeb. Txawm tias cov hlau nyias nyias, yog tias nws tau galvanized zoo, tuaj yeem tiv taus xeb thiab puas tsuaj zoo dua li hlau liab qab. Nws yog qhov tsim nyog rau cov haujlwm sab hauv tsev lossis sab nraum zoov xws li khi lossis ua laj kab.

Cov neeg tsim khoom siv hlau hauv Suav teb ua raws li cov qauv zoo nruj heev. Lawv tuaj yeem ua kom cov zinc lo rau zoo thiab cov txheej txheem sib xws. Txawm hais tias nws yog rau cov haujlwm lag luam lossis siv txhua hnub, cov hlau galvanized muab qhov sib npaug zoo ntawm kev ua tau zoo thiab tus nqi. Nws yog qhov kev xaiv zoo tshaj plaws rau cov neeg yuav khoom uas xav tau cov khoom siv ntev thiab tsis tas yuav saib xyuas ntau.
Xaus lus,hlau galvanizedmuaj kev tiv thaiv xeb zoo heev. Nws cov kev ua tau zoo raug cuam tshuam los ntawm ntau yam, tab sis feem ntau, nws tuaj yeem ua tau raws li qhov xav tau sib txawv hauv ntau yam lag luam. Nrog rau kev lees paub zoo los ntawm cov neeg tsim khoom hauv Suav teb, nws tseem yog qhov kev xaiv txhim khu kev qha hauv kev ua lag luam. Rau cov lag luam thiab cov tib neeg uas tab tom nrhiav kev daws teeb meem hlau siv tau, cov hlau galvanized uas tiv taus xeb yeej tsim nyog xav txog.
