Tam sim no, nrog rau kev loj hlob ntawm lub hnub ci photovoltaic kev lag luam, kev ua haujlwm thiab kev ruaj ntseg ntawm cov khoom siv hnub ci etching ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv hluav taws xob photovoltaic. Lub hauv paus granite, nrog nws zoo heev corrosion kuj thiab anti-aging zog, tau dhau los ua ib qho tseem ceeb ntawm cov khoom siv hnub ci etching.
Tiv thaiv kom muaj zog acid thiab alkali corrosion thiab tiv thaiv purity ntawm cov txheej txheem etching
Thaum lub sij hawm lub hnub ci etching txheej txheem, corrosive chemical reagents xws li hydrofluoric acid thiab nitric acid yog siv, uas muaj corrosive zoo rau cov khoom ntawm cov khoom. Ordinary hlau los yog lwm yam khoom siv hauv paus yog feem ntau ua rau corrosion thiab xeb tom qab kev sib cuag mus ntev nrog cov tshuaj no. Qhov no tsis tsuas yog paug cov tshuaj etching tab sis kuj cuam tshuam rau qhov raug thiab ruaj khov ntawm cov khoom siv.
Granite feem ntau yog tsim los ntawm cov zaub mov xws li quartz thiab feldspar, thiab nws cov khoom siv tshuaj muaj zog heev. Thaum ntsib qhov muaj zog acid thiab alkali ib puag ncig hauv cov txheej txheem etching, granite puag tuaj yeem tiv taus corrosion. Raws li cov ntaub ntawv los ntawm cov chaw kuaj kev tshaj lij, thaum lub hauv paus granite yog immersed nyob rau hauv 20% hydrofluoric acid tov rau 24 teev, lub thickness ntawm corrosion tsuas yog 0.001 hli, uas yog yuav luag negligible. Qhov no zoo heev corrosion kuj ua kom ntseeg tau tias purity ntawm cov tshuaj etching yuav tsis cuam tshuam los ntawm corrosion ntawm lub hauv paus thaum lub sij hawm ntev siv cov khoom siv etching, yog li lav qhov ruaj khov thiab sib xws ntawm cov txheej txheem etching thiab txhim kho cov txiaj ntsig ntawm photovoltaic hlwb.
Nws muaj kev ua haujlwm zoo los tiv thaiv kev laus thiab tuaj yeem txuas ntxiv lub neej kev pabcuam ntawm cov khoom siv
Thaum lub sij hawm tsim cov txheej txheem ntawm lub hnub ci etching cov cuab yeej, nws tsis tsuas yog yuav tsum tau tiv thaiv kev yaig ntawm cov tshuaj reagents, tab sis kuj muaj kev hloov kub thiab kev vibrations. Ordinary cov ntaub ntawv, nyob rau hauv lub sij hawm ntev ntawm thermal expansion thiab contraction thiab mechanical stresses, muaj feem xyuam rau cov teeb meem xws li kev laus thiab deformation, ua rau ib tug poob ntawm cov khoom raug thiab txawm yuav tsum tau hloov cov khoom los yog tag nrho lub tshuab ua ntej.
Granite muaj tus qauv sib txawv thiab hnav ris tsho sab hauv, thiab nws cov ntxhia yog qhov sib txuas nrog txhua lwm yam. Raws li kev siv ib txwm muaj, txawm tias tom qab ntau xyoo lawm, lub cev lub cev ntawm granite puag yuav tsis hloov pauv loj. Nws cov kev ua haujlwm tiv thaiv kev laus ua rau cov khoom siv hnub ci etching kom muaj kev ua haujlwm siab thiab ruaj khov rau lub sijhawm ntev. Piv txwv li, ib lub tuam txhab photovoltaic siv etching khoom nruab nrog granite puag. Tom qab ua haujlwm tas mus li rau 15 xyoo, qhov chaw qhov tseeb ntawm cov cuab yeej tseem tuaj yeem khaws cia tsis pub dhau ± 0.05mm, uas yuav luag zoo ib yam li qhov raug thaum cov cuab yeej siv thawj zaug. Piv nrog rau cov cuab yeej siv cov khoom siv zoo tib yam, lub voj voog txij nkawm txuas ntxiv los ntawm 2 mus rau 3 zaug, kev pabcuam lub neej ntawm cov khoom siv tau zoo dua qub, thiab cov khoom siv hloov pauv thiab tu cov nqi ntau tau txais kev cawmdim rau cov lag luam.
Kev ruaj ntseg kev ua tau zoo lav pab cov kev lag luam photovoltaic txo cov nqi thiab nce kev ua haujlwm
Qhov kev tiv thaiv corrosion thiab tiv thaiv kev laus ntawm granite puag muab kev ruaj khov thiab txhim khu kev qha kev ua haujlwm tau lees paub rau cov khoom siv hnub ci etching. Cov cuab yeej ruaj khov kev ua tau zoo txhais tau hais tias kev tsim khoom ntau dua thiab qis qis qis. Siv cov kab ntau lawm nrog lub peev xwm txhua xyoo ntawm 500MW ntawm cov cell photovoltaic ua piv txwv. Cov khoom siv etching nrog lub hauv paus granite tuaj yeem txo lub sijhawm poob rau kev saib xyuas los ntawm cov khoom siv corrosion thiab kev laus li ntawm 100 teev txhua xyoo, thiab nce tus nqi ntawm photovoltaic cell modules tsim los ntawm kwv yees li 2 lab yuan. Lub caij no, vim cov txheej txheem etching ruaj khov dua, cov khoom lag luam tawm tau nce los ntawm 2 mus rau 3 feem pua cov ntsiab lus, ntxiv txo cov nqi tsim khoom.
Nyob rau hauv lub backdrop ntawm lub hnub ci photovoltaic kev lag luam txoj kev nrhiav ntawm daim phiaj parity thiab txo nqi thiab kev txhim kho efficiency, granite bases, nrog rau lawv zoo heev zog ntawm corrosion kuj thiab anti-aging, tau dhau los ua tus yuam sij rau kev txhim kho kev ua tau zoo thiab txo cov nqi ntawm hnub ci etching khoom. Nws tsis tsuas yog muab kev lav phib xaub rau cov khoom lag luam zoo ntawm cov cell photovoltaic, tab sis kuj tseem pab txhawb kev txhim kho kom ruaj khov ntawm tag nrho cov kev lag luam photovoltaic.
