Galvanized Steel rau Hnub Ci Mounting: Qhov Kawg Qhia rau PV Systems
1. Kev Taw Qhia: Qhov Kev Xav Tau Zoo Tshaj Plaws rau PV Infrastructure
Lub ntiaj teb tab tom nthuav dav lub zog tauj dua tshiab. Hnub ci PV ua lub luag haujlwm tseem ceeb hauv kev hloov pauv ntsuab thoob ntiaj teb. Nws qhov nruab nrab loj hlob sai dua txhua xyoo.
CPIA (Tuam Tshoj Photovoltaic Industry Association) kwv yees lub ntiaj teb tshiab hnub ci PV muaj peev xwm yuav ncav cuag 500GW–667GW nyob rau hauv 2026. Meanwhile, SolarPower Europe qhia thoob ntiaj teb cumulative ntsia PV muaj peev xwm yuav tshaj 7TW los ntawm 2029 nyob rau hauv nws nruab nrab txoj kev loj hlob scenario.
Raws li Tuam Tshoj Lub Chaw Tswj Xyuas Hluav Taws Xob Hauv Tebchaws, Tuam Tshoj lub hnub ci nruab hnub muaj peev xwm nce mus txog 1,200GW (1.2TW) thaum kawg ntawm 2025. Daim duab no sawv cev rau 35.4% xyoo-ntawm- xyoo nce.
Hnub ci mounting qauv yog lub hauv paus ntawm PV system stability thiab durability. Hnub ci brackets ua raws li "steel nraub qaum" ntawm PV nroj tsuag. Lawv yuav tsum ua siab ntev rau sab nraum zoov hnyav rau ntau xyoo lawm.
Cov xwm txheej no muaj xws li qhov kub thiab txias, siab humidity, corrosion, thiab mechanical stress. Lawv tsim muaj kev thov rau siab - cov ntaub ntawv ua tau zoo.
Galvanized steel yog cov khoom siv sab saum toj rau hnub ci mounting. Nws muab kev ua haujlwm zoo, lub zog, thiab kev siv nyiaj txiag zoo. Cov lus qhia no suav nrog cov ntsiab lus, kev tsim khoom, qhov zoo, hom, kev siv, kev xaiv, kev teeb tsa, thiab cov qauv. Nws pab PV developers, installers, thiab investor txiav txim siab zoo dua.
Tshaj li 10 xyoo dhau los muab cov hlau galvanized rau kev lag luam photovoltaic, peb tau pom ua ntej yuav ua li cas xaiv cov khoom siv zoo tuaj yeem ua lossis tawg lub hnub ci project. Peb tau saib cov neeg siv khoom txuag tau ntau lab los ntawm kev xaiv siab - zoo corrosion-resistant galvanized steel rau lawv cov tshuab mounting- thiab peb kuj tau pom cov nqi tsis zoo los ntawm kev txiav cov ces kaum ntawm txheej tuab lossis cov khoom siv zog.
Raws li lub ntiaj teb hnub ci boom nrawm, peb tab tom sau phau ntawv qhia no los qhia txhua yam peb tau kawm txog galvanized steel rau hnub ci mounting.
Vim li cas Galvanized Steel tseem yog qhov kev xaiv zoo tshaj plaws rau hnub ci Mounts
Yog tias koj tau siv txhua lub sijhawm tshawb nrhiav PV mounting cov ntaub ntawv, tej zaum koj tau pom tsis muaj kev sib cav txog aluminium vs. steel vs. composite cov ntaub ntawv. Tom qab 12 xyoo hauv kev lag luam no, peb tuaj yeem qhia koj ib yam nrog qhov tseeb: rau 90% ntawm cov phiaj xwm hnub ci, xeb-cov galvanized steel muaj qhov sib npaug zoo tshaj plaws ntawm kev ua haujlwm, lub zog, thiab tus nqi.
Corrosion yog tus yeeb ncuab #1 ntawm cov qauv hnub ci sab nraum zoov. Los nag, av noo, tshuaj tsuag ntsev, thiab cov pa phem hauv kev lag luam noj tam sim ntawm cov hlau tsis muaj kev tiv thaiv, ua rau ua tsis tiav ntxov ntxov thiab raug nqi hloov. Kub-dip galvanized steel daws qhov teeb meem no nrog ob txheej tiv thaiv:
Lub cev tawv tawv uas thaiv cov dej noo thiab cov kab mob corrosive
Sacrificial anode tiv thaiv- yog tias cov txheej tau khawb, zinc corrodes ua ntej kom txuag tau cov hlau hauv qab
Peb lub hnub ci zoo tshaj plaws -qib galvanized steel dhau 2,000-teev ASTM B117 ntsev tshuaj tsuag, txhais tau tias nws yuav kav ntev 25+ xyoo txawm nyob rau hauv ib puag ncig hnyav ntug hiav txwv. Qhov ntawd ntev tshaj li qhov tsim lub neej ntawm feem ntau cov hnub ci vaj huam sib luag lawv tus kheej.
2. Galvanized Steel rau PV Mounts yog dab tsi?
Galvanized steel rau hnub ci mounting yog cov khoom tshwj xeeb kho steel. Nws siv cov txheej txheem galvanizing los txhim kho corrosion kuj zoo heev.
Nws yog tsim tshwj xeeb rau PV mounting systems. Nws tuaj yeem tiv taus ntev -ntev tawm sab nraum zoov thiab ua kom ruaj khov rau 25 xyoo lossis ntau dua.
Txheej txheem ntau lawm
Muaj ob txoj hauv kev tseem ceeb rau hnub ci- qib galvanized steel: kub-dip galvanizing thiab electro-galvanizing.
Kub-Dip Galvanizing: Feem ntau siv hauv PV tej yaam num. Nws muab kev tiv thaiv corrosion zoo dua.
Cov kauj ruam tseem ceeb:
Ntxuav: Cov neeg ua haujlwm tshem tawm tag nrho cov av, roj, thiab xeb los ntawm cov hlau substrate.
Fluxing: Cov hlau yog dipped rau hauv cov tshuaj flux los npaj rau kev sib raug zoo zinc.
Zinc Dipping: Raus cov hlau hauv molten zinc ntawm kwv yees li 450 degree. Ib ntom zinc- hlau alloy txheej txheej.
Txias: Cov hlau txias txias, thiab zinc txheej hardens rau hauv cov txheej tiv thaiv nruj.
Siab -Kev Ua Tau Zoo: Cov khoom lag luam hwm ntxiv rau kev sib tsoo, cua tshuab tshuab, npaus dov, thiab passivation los txhawb lub zog ntxiv.
Electro-Galvanizing: Siv electrolysis los tso ib txheej zinc nyias. Vim muaj kev tiv thaiv corrosion qis, nws tsuas yog me me lossis sab hauv PV tej yaam num.
3. Core Advantages rau PV daim ntawv thov
3.1 Superior Corrosion Protection
Corrosion yog qhov kev hem thawj loj tshaj plaws rau cov qauv hlau sab nraum zoov. PV brackets ntsib tas li raug los nag, av noo, tshuaj tsuag ntsev (cov ntug dej hiav txwv), thiab muaj kuab paug.
Galvanized steel ua ib qho kev thaiv lub cev uas thaiv cov dej noo thiab cov kab mob corrosive. Qhov tseem ceeb tshaj, nws muab kev tiv thaiv kev txi: yog tias cov txheej txheej khawb, zinc corrodes ua ntej los tiv thaiv cov hlau hauv qab.
Zoo kub-dip galvanized steel hla 2,000- teev ntsev tsuag tshuaj ntsuam xyuas. Qhov no ua kom lub neej ua haujlwm ntev hauv cov ntug hiav txwv hnyav, kev lag luam, thiab cov av noo ib puag ncig.

PV panels, tshwj xeeb tshaj yog cov khoom siv hluav taws xob- nplai modules, tsim cov khoom hnyav. Brackets yuav tsum tiv taus cua, hnyav daus, thiab seismic rog.
Galvanized steel tuav lub zog siab ntawm cov hlau nrog lub zog zoo heev - rau - qhov hnyav piv. Tshwj xeeb hnub ci- qib galvanized steel muaj:
Tawm Zog: Tshaj 600MPa
Tensile zog: Tshaj 700MPa
Elongation: Ntau dua lossis sib npaug li 20%
Nws nyob ruaj khov nyob rau hauv huab cua huab cua, tiv taus cua ceev txog 216 km / h thiab kub mus txog -40 degree.
3.3 Tus nqi zoo heev -Kev ua tau zoo
Txawm hais tias galvanized steel muaj tus nqi siab dua me ntsis dua li cov hlau zoo tib yam, nws lub sijhawm ntev - tus nqi yog qhov zoo dua.
Kev Kho Mob Tsawg: Nws xav tau kev saib xyuas tsawg tsawg thiab tuaj yeem kav ntev dua 50 xyoo, tshem tawm cov xeb ntau zaus thiab hloov cov nqi.
Eco- Tus phooj ywg: Hlau thiab zinc yog cov khoom siv rov ua dua tshiab, txhawb nqa kev lag luam ncig lub hom phiaj ntawm cov phiaj xwm hluav taws xob tauj dua tshiab.
Superior rau Aluminium: Piv rau txhuas alloys, galvanized steel muab lub zog muaj peev xwm ntawm tus nqi qis, ua rau nws tus nqi ntau tshaj -kev xaiv zoo rau feem ntau PV tej yaam num.
