1.Vim li cas galvanized coils (electroplated zinc) tsis haum?
Tsis txaus Corrosion Resistance
Nyias Zinc Txheej: Cov thawv thauj khoom huab cua mus ncig thoob ntiaj teb, ntsib qhov chaw hnyav-los ntawm cov chaw ntub dej mus rau de-icing tshav dav hlau khiav hauv lub caij ntuj no. Cov zinc txheej ntawm cov txheej txheem electroplated galvanized zoo tib yam (feem ntau 10-30µm) sai sai deteriorates nyob rau hauv cov xwm txheej no vim khawb thiab corrosion, ua rau xeb ntawm lub substrate.
Kev Tiv Thaiv Kev Txhaum Cai Txwv Txwv: Thaum cov zinc txheej raug khawb lossis hnav tawm, nws "sacrificial anode" kev tiv thaiv tsis tu ncua, thiab xeb kis sai sai thoob plaws hauv cov hlau substrate.
Qhov Teeb Meem Ua tiav
Cov Txheej Txheem Tsis Zoo: Cov thawv ntim khoom thauj huab cua feem ntau xav tau siab - zoo, puas tsuaj - tiv taus, thiab huab cua- tiv taus cov xim pleev xim rau kev lees paub thiab kev tiv thaiv ntxiv. Ib qho yooj yim electroplated nto hinders xim adhesion, yooj yim ua rau xim tev.
Compatibility nrog Topcoat: Zinc txheej tuaj yeem tiv thaiv qee cov xim, cuam tshuam rau xim kho thiab ua rau muaj qhov tsis xws luag.
2.Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm aluminium alloys siv hauv cov thawv ntim khoom cua?
Qhov zoo:
Lub teeb yuag thiab siab zog: Nws qhov txiaj ntsig loj tshaj plaws yog nws qhov hnyav hnyav dua piv rau cov hlau.
Excellent corrosion resistance: Aluminum naturally forms a dense oxide film on its surface, providing strong corrosion resistance and preventing red rust.
Ib qho yooj yim txij nkawm: paub tab kho deg technology.
Qhov tsis zoo: tus nqi siab dua thiab qis zog piv rau cov hlau ntawm tib lub ntim.
3.Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm cov ntaub ntawv sib xyaw (xws li iav fiber ntau thiab carbon fiber reinforced plastics)?
Qhov zoo:
Lub teeb hnyav heev: sib dua li aluminium alloys.
Kev tiv thaiv corrosion zoo heev: Ua tiav rau cov dej noo, tshuaj tsuag ntsev, thiab tshuaj lom neeg.
Kev tsim tau zoo heev: tuaj yeem ua pwm rau hauv ib qho, txo cov seams thiab ua rau cov qauv ua tiav ntau dua.
Kev saib xyuas yooj yim.
Disadvantages: Tus nqi pib tsim khoom siab tshaj plaws; cuam tshuam kev tiv thaiv thiab kho txoj kev sib txawv ntawm cov hlau.
4.Nws puas tuaj yeem siv "steel"?
Weathering steel: Ib txheej tiv thaiv xeb ua rau ntawm qhov chaw los ntawm cov hlau alloy (xws li Cu, P, Cr, Ni), tiv thaiv corrosion los ntawm kev nkag mus tob. Txawm li cas los xij, yuav tsum muaj txheej txheej tshwj xeeb.
Ua ntej- kho siab- cov ntawv steel muaj zog: xws li cov tshuaj phosphate lossis siv cov txheej txheem Dacromet. Cov kev kho mob no muab kev tiv thaiv corrosion zoo tshaj thiab txheej adhesion piv rau cov khoom siv electro-galvanizing.
Kub-dip galvanized steel ntawv: Txawm tias zoo dua li electro-galvanizing, lawv qhov zoo thiab qhov hnyav teeb meem ua rau lawv tsis tshua muaj nyob rau hauv kev lag luam aerospace.
5.Dab tsi yog cov lus xaus thiab cov lus pom zoo?
Kev hais lus: nws cov kev tiv thaiv corrosion, kev kho deg zoo sib xws, thiab kev ua haujlwm ntev tsis tuaj yeem ua tau raws li qhov xav tau ntawm huab cua thauj khoom.
Kev hais lus nyiaj txiag: nws lub neej ua haujlwm luv luv thiab cov nqi kho mob siab ua rau nce tag nrho cov nqi ntawm lub neej.
Los ntawm kev xav txog kev lag luam: nws tsis ua raws li cov qauv kev xaiv cov khoom tseem ceeb thiab tsis tuaj yeem dhau cov ntawv pov thawj kev lag luam nruj.
