1.Dab tsi cuam tshuam cov txheej txheem galvanizing muaj qhov sib txawv ntawm lifespan?
Galvanized coils yog tsim los ntawm txheej txheej coiled txias- dov steel ntawv nrog zinc txheej hauv cov xov tooj ntawm tes siv hluav taws xob tam sim no. Galvanized lub kaum sab xis steel yog tsim los ntawm immersing pre- tsim, welded, los yog forged lub kaum sab xis steel rau molten zinc rau galvanizing.
Galvanized coils muaj txheej txheej zinc txheej, uas feem ntau yog sib xws, du, thiab ua kom zoo nkauj. Galvanized lub kaum sab xis steel muaj cov zinc txheej tuab, uas tej zaum yuav tsis sib npaug, tshwj xeeb tshaj yog nyob rau ntawm cov npoo thiab cov ces kaum, thiab tej zaum yuav muaj zinc tawg rau ntawm qhov chaw.
Los ntawm kev tsim khoom ib leeg, zinc txheej ntawm kub -dip galvanized lub kaum sab xis steel yog tuab dua li ntawm cov hlau electro-galvanized coils. Ib txheej zinc thicker txhais tau tias zinc tuaj yeem noj ntau dua, yog li ua rau lub neej ntev dua.
2.Yuav ua li cas zinc txheej thickness cuam tshuam rau lifespan txawv?
Galvanized lub kaum sab xis steel (kub-dip galvanized): zinc txheej yog tuab heev, feem ntau tshaj 85µm, los yog tuab dua. Nyob rau hauv cov huab cua ib puag ncig, nws lub neej kev pabcuam tuaj yeem ncav cuag 20-50 xyoo lossis ntev dua.
Galvanized coil (electro-galvanized): Cov txheej zinc yog thinner, feem ntau ntawm 5-20µm. Raws li tib lub sijhawm, nws lub neej kev pabcuam tsuas yog ob peb xyoos mus rau kaum xyoo.
3.Yuav ua li cas cov duab thiab cov qauv cuam tshuam rau lifespan txawv?
Kev tiv thaiv kaum: Lub kaum sab xis steel muaj cov npoo ntse. Thaum lub sij hawm kub -dip galvanizing, cov zinc molten ntawm cov npoo tej zaum yuav ploj vim qhov nro, tab sis cov txheej tuab kuj tseem tsim. Qhov tseem ceeb tshaj, kub-dip galvanizing tsim cov txheej txheem alloy muaj zog ntawm cov npoo. Hauv qhov sib piv, thaum electro-galvanized coils tau ua tiav tom qab (xws li khoov thiab txiav) rau hauv cov khoom, cov zinc txheej nyias ntawm cov npoo tau yooj yim puas, ua rau corrosion pib los ntawm cov ntsiab lus no.
Kev puas tsuaj: Raws li cov khoom siv, lub kaum sab xis hlau yog qhov cuam tshuam rau kev cuam tshuam thaum lub sijhawm thauj mus los thiab kev teeb tsa, tab sis vim nws cov zinc txheej tuab, cov khawb me me muaj qhov cuam tshuam me me. Galvanized coils (tshwj xeeb tshaj yog cov khoom nyias nyias), ntawm qhov tod tes, muaj cov zinc txheej thinner thiab yooj yim dua khawb thiab puas.
4.Dab tsi yog qhov tseem ceeb ntawm kev ua neej nyob txawv?
Qhov sib txawv tseem ceeb tsis yog tias nws yog "coil" lossis "lub kaum sab xis steel," tab sis yog cov txheej txheem galvanizing siv (electro-galvanizing vs. kub-dip galvanizing) thiab zinc txheej kawg thickness.
Feem ntau hais lus, feem ntau ntawm galvanized lub kaum sab xis ntawm lub khw yog kub-dip galvanized, thaum galvanized coils (tshwj xeeb yog cov khoom siv hauv tsev thiab xim-coated substrates) feem ntau yog electro-galvanized. Nyob rau hauv qhov kev sib piv no, qhov corrosion kuj ntawm galvanized lub kaum sab xis steel deb tshaj ntawm cov khoom ua tiav los ntawm electro-galvanized coils, nrog rau qhov sib txawv muaj peev xwm ncav cuag ob peb zaug lossis kaum zaus.
5.Peb yuav tsum xaiv qhov kev xaiv zoo li cas rau cov xwm txheej sib txawv?
Rau cov ntawv thov uas xav tau kev ua haujlwm siab, xws li cov qauv kev txhawb nqa, sab nraum zoov thav duab, thiab cov yees, kub -dip galvanized lub kaum sab xis steel lossis lwm yam kub -dip galvanized profiles yuav tsum yog thawj qhov kev xaiv.
Rau cov ntawv thov uas yuav tsum muaj kev tiv thaiv corrosion tsawg dua thiab qhov chaw zoo, xws li cov ntaub thaiv sab hauv tsev, cov khoom siv hluav taws xob, thiab cov khoom siv sib sib zog nqus, electro-galvanized coils yog qhov kev xaiv pheej yig.
Rau cov haujlwm uas xav tau siab heev thiab ib puag ncig hnyav, kub -dip galvanized steel coils tuaj yeem siv los ua cov khoom siv raw rau kev ua haujlwm.
