1.Vim li cas ua ntej-coated steel yob yog qhov kev xaiv zoo tshaj plaws?
Huab cua zoo heev thiab Corrosion Resistance:
Substrate: Siab-lub zog galvanized steel ntawv feem ntau yog siv los ua lub substrate, muab kev tiv thaiv corrosion ntau zaus ntawm cov ntawv zoo tib yam galvanized. Nws yog tshwj xeeb tshaj yog tiv taus rau qhov complex polluting ib puag ncig raws railway kab (xws li av av, ntsev, de-icing agents, thiab industrial emissions).
Txheej: Qhov saum npoo siv cov txheej txheem zoo heev, xws li PVDF (fluorocarbon) lossis HDP ( huab cua siab - polyester ). Cov coatings no muaj zog heev UV tiv thaiv, ua kom ntev - lub sij hawm (feem ntau 15-}25 xyoo) colourfastness, non-chalking, thiab tsis poob ntawm gloss, tuav ib tug check tsos.
Siab zog thiab zoo Rigidity:
Cov hlau substrate muab kev tiv thaiv zoo heev rau cua siab, cuam tshuam, thiab kev co, muaj peev xwm tiv taus lub zog pulsating thiab muaj zog cua siab tsim los ntawm siab - tsheb ciav hlau ceev, ua kom muaj kev ruaj ntseg thiab ruaj khov.
Kev ua tau zoo heev:
Raws li tau hais ua ntej, xim -coated coils yog qhov tsim nyog rau kev sib sau ua ntu zus. Ntau tus ntoo khaub lig- cov duab ntu uas yuav tsum tau ua rau lub suab tsis sib haum (xws li hom nkhaus, kaum sab xis, thiab louvered) tuaj yeem ua tau zoo kom ua tau raws li qhov sib txawv acoustic, qauv, thiab kev zoo nkauj. Nws tuaj yeem ua tau yooj yim xuas nrig ntaus (kom micro- suab perforated-absorbing vaj huam sib luag), folded, thiab txiav kom hloov mus rau qhov nyuaj installation nodes.
2.Dab tsi yog qhov yuav tsum tau ua rau xim -coated yob substrates rau railway sound barriers?
Aluminized zinc-coated steel ntawv (AZ150, zinc-aluminium-magnesium steel ntawv tseem zoo dua) yog qhov zoo dua, nrog cov txheej txheem hnyav hnyav (xws li AZ150). Lub thickness yog feem ntau 0.7mm-1.5mm, txiav txim siab raws li cua load xam.
3.Dab tsi yog qhov yuav tsum tau ua rau cov xim -coated coil txheej txheej ntawm railway suab teeb meem?
High- huab cua- cov coatings resistant yuav tsum tau:
• PVDF (fluorocarbon) txheej: Siv rau siab -tus qauv siab- kev tsheb ciav hlau ceev, thaj chaw ntug hiav txwv, thiab thaj chaw uas muaj hluav taws xob UV siab.
• HDP (siab- huab cua- resistant polyester)) txheej: Siv rau feem ntau inland pa tsheb ciav hlau tej yaam num. Ordinary polyester txheej tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua.
4.Dab tsi yog hom xim -coated roll sound barrier panels?
Tsis yog- suab-absorbing (reflective) panels:
Pav ca panels los yog panels nrog ntxiv dag zog.
Feem ntau rau lub suab rwb thaiv tsev thiab suab barrier muaj nuj nqi; qauv yooj yim.
Suab -absorbing panels:
Micro-perforated vaj huam sib luag: Hom ntau tshaj plaws. Ntau lub micropores raug xuas nrig ntaus rau hauv lub vaj huam sib luag, tsim lub suab nrov nrov- nqus cov qauv ua ke nrog cov kab noj hniav tom qab nws thiab lub suab - nqus cov khoom.
Hom Louvre: Lub vaj huam sib luag muaj qhov qhib, muab ob qho tib si txo suab nrov thiab ua haujlwm cua.
5.Dab tsi yuav tsum tau ua kom ntseeg tau thaum xaiv cov ntaub ntawv rau ib qhov project tshwj xeeb?
Qhia meej meej cov kev qhia tshwj xeeb: Qhia meej hom substrate (AZ150 aluminium-zinc coated steel), txheej txheej txheej (PVDF/HDP), zaj duab xis thickness, xim qauv, thiab yuav tsum muaj huab cua tiv thaiv ntsuas ntsuas hauv daim ntawv cog lus yuav khoom.
Xaiv cov neeg muab kev ntseeg siab: Xaiv cov loj- nplai xim-coated steel sheet manufacturers nrog kev paub hauv kev tsheb ciav hlau thiab lub suab tswj kev ua haujlwm zoo.
Tsom ntsoov rau kev tsim qauv: Lub suab thaiv yog qhov system; Dhau li ntawm cov vaj huam sib luag, qhov zoo thiab kev tsim ntawm nws cov qauv kev txhawb nqa, cov ntsaws ruaj ruaj, thiab suab -cov ntaub ntawv nqus dej yog qhov tseem ceeb sib npaug.
