1.Vim li cas thiaj muaj xim -coated steel rolls "xav" rau siv nyob rau hauv photovoltaic mounting systems?
Aesthetically pleasing: Rau qee qhov kev faib tawm photovoltaic cov haujlwm uas yuav tsum tau ua kom zoo nkauj (xws li lub ru tsev), ua ntej -coated steel coils tuaj yeem muab qhov sib haum xeeb zoo sib xws uas phim lub tsev xim.
Kev tiv thaiv corrosion zoo: Piv rau cov ntawv hlau dub zoo tib yam, cov txheej txheem ua ntej -coated steel coils muab lub cev muaj zog tiv thaiv huab cua noo thiab kev xeb.
Tus nqi qis dua: Raws li cov nqi ntawm cov khoom siv thawj zaug, qee cov qib ntawm pre-coated steel coils yuav raug nqi ntau dua- zoo dua li kub -dip galvanized kev txhawb nqa (tab sis qhov no tuaj yeem txi ntev - lub sij hawm cia siab).
2.Vim li cas xim -coated steel yob tsis yog lub hauv paus thiab kev xaiv zoo tshaj plaws rau photovoltaic mounting systems?
Corrosion Risk ntawm Hlais Ntug thiab Kev Ua Haujlwm Kev Puas Tsuaj (Qhov Teeb Meem Tseem Ceeb)
Kev tiv thaiv corrosion ntawm pre-coated steel coils cia siab rau kev ncaj ncees ntawm lawv cov txheej txheej. Thaum lawv raug txiav, xuas nrig ntaus, thiab drilled los tsim kev txhawb nqa, cov hlau substrate ntawm cov ntsiab lus ua haujlwm no ncaj qha mus rau ib puag ncig.
Cov kev txiav tawm no dhau los ua qhov pib rau corrosion. Corrosive media xws li ya raws thiab ntsev tuaj yeem nkag los ntawm cov kev txiav no, kis hauv qab txheej thiab ua rau nws hlwv, tev, thiab thaum kawg corrode tag nrho cov khoom. Cov txheej txheem no yog hu ua "txiav ntug corrosion."
Kev Sib Tw ntawm Huab Cua Resistance Ratings
Ordinary polyester pre-coated steel coils (PE) siv hauv kev tsim kho tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua rau 25-xyoo huab cua tiv thaiv thiab nws yuav ua rau chalking thiab fading.
Txawm tias muaj kev ua tau zoo -PVDF txheej txheej, lawv lub neej tsim feem ntau yog nyob ib ncig ntawm 15-20 xyoo, xa mus rau qhov xwm txheej uas cov txheej txheem tsis zoo, uas tseem poob qis ntawm 25-xyoo lub neej uas yuav tsum tau muaj rau kev txhawb nqa.
3.Dab tsi yog cov teeb meem loj tshwm sim los ntawm ib puag ncig hnyav?
Nyob rau hauv cov ntug dej hiav txwv, high salinity ua sai corrosion ntawm hlau ntawm qhov chaw txiav.
Hauv cov cheeb tsam kev lag luam, cov kua qaub nag thiab tshuaj lom neeg ua kom cov txheej txheem tsis ua haujlwm.
Nyob rau hauv siab - thaj tsam qhov siab, muaj zog ultraviolet hluav taws xob ua kom cov txheej chalking thiab aging.
4.Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm kev siv kub -dip galvanized steel ua cov khoom siv hluav taws xob photovoltaic?
kiag li mainstream. Cov txheej yog tuab (feem ntau ntau dua lossis sib npaug ntawm 65μm) thiab muaj cov cathodic tiv thaiv kev ua haujlwm ntawm "sacrificial anode", uas tuaj yeem tiv thaiv lub substrate txawm tias nws raug txiav lossis khawb, thiab lub neej tuaj yeem ncav cuag ntau tshaj 25 xyoo.
Nws muaj qhov pom yooj yim (nyiaj -dawb), hnyav hnyav, thiab nws cov khoom ua rau muaj kuab paug.,
5.Dab tsi yog cov lus pom zoo rau kev siv ua ntej-coated steel coils hauv photovoltaic mounting systems?
Xaiv nrog ceev faj: Tshwj tsis yog tias qhov project yog nyob rau hauv ib qho chaw qhuav, tsis muaj kuab paug hauv cheeb tsam nrog kev siv nyiaj tsawg heev thiab kev cia siab ntawm 10-15 xyoo, siv cov hlau coated ua ntej ua cov khoom tseem ceeb rau photovoltaic (PV) mounting systems tsis pom zoo.
Yog tias nws yuav tsum tau siv, siv cov kev daws teeb meem nruj:
Xaiv lub siab- huab cua- cov tshuaj tiv thaiv: PVDF lossis qib siab txheej txheej yuav tsum tau siv; polyester zoo tib yam siv tsis tau.
Xaiv lub tuab -coated substrate: Lub substrate yuav tsum yog galvanized steel, thiab zinc txheej hnyav tau pom zoo kom tsis pub tsawg tshaj Z180 los muab kev tiv thaiv xeb txaus.
Kho txhua qhov chaw txiav thiab tshuab nrog kev tiv thaiv- kev kho corrosion: Qhov no yog kauj ruam tseem ceeb tshaj plaws. Txhua qhov chaw txiav thiab laum yuav tsum tau coated nrog zinc-nplua nuj primer los yog tshwj xeeb los tiv thaiv- xeb xim los tsim cov txheej txheem tiv thaiv zoo. Qhov no yog tus nqi zog ntxiv uas yuav tsum tau muab xam rau hauv.
Ua ntej cov kev daws teeb meem tseem ceeb: Rau PV fais fab nroj tsuag npaj ua haujlwm rau ntau tshaj 25 xyoo, kub-dip galvanized steel mounting systems tseem yog qhov kev xaiv zoo tshaj plaws thiab kev lag luam. Lawv cov nqi-kev ua tau zoo thiab kev nyab xeeb thoob plaws hauv lawv lub neej tag nrho deb tshaj cov uas pheej hmoo ua ntej-coated steel coil tov.
