1.How ua tuab ntawm Galvanized Txheej cuam tshuam rau kev pabcuam lub neej?
Txheem txheej txheem (piv txwv li, 180-275g / m² ntawm ob sab): xws li thaj chaw tsis muaj sia), nrog rau kev tiv thaiv corrosion lab), nrog rau kev tiv thaiv corrosion lab)
Cov txheej txheej tuab (piv txwv li, 350-600g / m² ntawm ob tog): Thaj chaw siab, thiab huab cua hiav txwv corrosion ntawm li 20-30 xyoo.
Nco tseg: Rau txhua 100g / m² ntxiv rau hauv coating thickness, kev tawm tsam lub neej corrosion, tau txuas ntxiv los ntawm 5-8 xyoos (nyob rau hauv tib qho chaw).
2.Yog ib puag ncig ib puag ncig cuam tshuam rau lub neej pabcuam?
Cov chaw qis-xeb ib puag ncig (xws li thaj chaw thaj chaw tsis muaj cov muaj kuab paug): Quav Zinc qeeb, nrog zinc txheej poob ntawm kwv yees li 1-3g / m² / xyoo. Tuab txheej txheem tuaj yeem yooj yim kav ntev tshaj 25 xyoos.
Ib nrab-corrosion ib puag ncig (xws li thaj chaw sab nrauv thiab thaj chaw ntawm thaj chaw muaj 3,8g / xyoo, xav tau ib qho kev tiv thaiv tsawg kawg 275g / m² los lav lub neej ntawm 15-20 xyoo.
High-corrosion ib puag ncig (xws li nyob rau hauv 3 km ntawm ntug dej, thiab nyob rau hauv cov cheeb tsam cuam tshuam los ntawm acid los nag): m² / xyoo, xav tau ib txheej tsawg kawg 450g / m². Kev ntsuas kev tiv thaiv kev tiv thaiv corrosion (xws li pleev xim) pom zoo; Txwv tsis pub, xeb hauv zos yuav tshwm sim tsis pub dhau 10 xyoo.
3.Thaum muaj kev teeb tsa thiab kev saib xyuas cuam tshuam rau lub neej pabcuam?
Yog tias lub bracket txheej txheej yog khawb hauv kev teeb tsa (piv txwv li, vim nws raug cov plua plav hluav taws xob (ua kom muaj zog hauv zos hluav taws xob), xeb yuav ua kom nrawm dua thiab ua kom luv dua nws lub neej.
Nquag tu cov khib nyiab saum npoo thiab kho cov txheej txheem puas tuaj yeem txuas ntxiv rau lub sij hawm tiv thaiv corrosion los ntawm 10% -20%.
4.Qhov cov qauv tsim qauv hauv kev lag luam?
Lub photovoltaic kev lag luam feem ntau yuav tsum tau hais tias kev pabcuam lub neej ntawm cov nkhaus sib phim uas ntawm photovoltaic modules (25-30 xyoo). Yog li ntawd, kev xaiv ntawm galvanized daim ntawv hlau yuav tsum ua kom tau raws li cov yuav tsum tau ua hauv qab no:
Inland cov chaw qis-corrosion: 275g / m² / m² lossis siab dua ntawm ob tog tau pom zoo (sib raug rau zinc txheej tuab ntawm kwv yees li 40μm).
Cov ntug dej hiav txwv lossis kev ua haujlwm qias neeg: 450G / m² / m² lossis ntau dua ntawm ob sab yog qhov pom zoo ntawm kwv yees li ntawm 65 xyoos
Qee cov qauv thoob ntiaj teb (xws li IEC cov qauv) yuav tsum muaj tshuaj ntsev tsawg kawg 1000 teev (sib npaug rau ntau dua 15 xyoos ntawm thaj chaw tiv thaiv kab hiav txwv).
5. Kev siv kev coj ua thiab txij nkawm, dab tsi yog anti-corrosion lub neej ntawm galvanized ntawv ntawm lub photovoltaic bracket?
Tsawg-corrosion ib puag ncig: 20-30 xyoo (txheej tuab);
Nruab nrab-corrosion ib puag ncig: 15-20 xyoos (nruab nrab-tuab txheej);
High-corrosion ib puag ncig: 10-15 xyoos (tuab txheej + yuav tsum muaj tiv thaiv ntxiv)
