Lub hauv paus granite: Tus neeg saib xyuas kev tiv thaiv corrosion thiab tiv thaiv kev laus rau cov khoom siv hnub ci etching.

Tam sim no, nrog rau kev loj hlob ntawm kev lag luam photovoltaic hnub ci, kev ua tau zoo thiab kev ruaj khov ntawm cov khoom siv hnub ci etching ua lub luag haujlwm tseem ceeb hauv kev tsim cov hlwb photovoltaic ua haujlwm siab. Lub hauv paus granite, nrog nws qhov kev tiv thaiv corrosion zoo heev thiab cov khoom tiv thaiv kev laus, tau dhau los ua qhov tseem ceeb ntawm cov khoom siv hnub ci etching.

Tiv taus cov kua qaub thiab alkali corrosion muaj zog thiab tiv thaiv qhov purity ntawm cov txheej txheem etching
Thaum lub sijhawm ua haujlwm hnub ci etching, cov tshuaj reagents corrosive heev xws li hydrofluoric acid thiab nitric acid raug siv, uas muaj cov teebmeem corrosive zoo rau cov khoom ntawm cov khoom siv. Cov hlau ib txwm lossis lwm yam khoom siv hauv paus yuav raug xeb thiab xeb tom qab kev sib cuag ntev nrog cov tshuaj lom neeg no. Qhov no tsis yog tsuas yog ua rau cov tshuaj etching paug xwb tab sis kuj cuam tshuam rau qhov tseeb thiab kev ruaj khov ntawm cov khoom siv.

Granite feem ntau yog ua los ntawm cov zaub mov xws li quartz thiab feldspar, thiab nws cov khoom siv tshuaj lom neeg ruaj khov heev. Thaum ntsib cov kua qaub thiab alkali muaj zog hauv cov txheej txheem etching, lub hauv paus granite tuaj yeem tiv taus corrosion zoo. Raws li cov ntaub ntawv los ntawm cov chaw kuaj kev tshaj lij, thaum lub hauv paus granite raug muab tso rau hauv 20% hydrofluoric acid kua rau 24 teev, qhov tuab ntawm qhov corrosion tsuas yog 0.001 hli, uas yuav luag tsis pom tseeb. Qhov kev tiv thaiv corrosion zoo heev no ua kom ntseeg tau tias qhov huv ntawm cov kua etching yuav tsis raug cuam tshuam los ntawm qhov corrosion ntawm lub hauv paus thaum lub sijhawm siv cov khoom siv etching ntev, yog li lav qhov ruaj khov thiab sib xws ntawm cov txheej txheem etching thiab txhim kho cov txiaj ntsig ntawm cov hlwb photovoltaic.
Nws muaj kev ua tau zoo heev los tiv thaiv kev laus thiab tuaj yeem ua kom lub neej ua haujlwm ntawm cov khoom siv ntev dua
Thaum lub sijhawm tsim cov khoom siv hnub ci etching, nws tsis yog tsuas yog yuav tsum tau nyiaj dhau qhov kev puas tsuaj ntawm cov tshuaj reagents, tab sis kuj tseem muaj kev hloov pauv kub thiab kev co tshuab. Cov ntaub ntawv ib txwm muaj, nyob rau hauv qhov cuam tshuam ntev ntawm kev nthuav dav thermal thiab kev cog lus thiab kev ntxhov siab tshuab, feem ntau muaj teeb meem xws li kev laus thiab kev hloov pauv, ua rau kev poob qis ntawm qhov tseeb ntawm cov khoom siv thiab txawm tias qhov xav tau hloov cov khoom lossis tag nrho lub tshuab ua ntej.

Granite muaj cov qauv sab hauv uas tuab thiab sib xws, thiab nws cov pob zeb siv lead ua ke zoo sib xws. Nyob rau hauv cov xwm txheej siv ib txwm muaj, txawm tias tom qab ntau xyoo lawm, cov khoom siv ntawm lub hauv paus granite yuav tsis hloov pauv ntau. Nws cov kev ua haujlwm tiv thaiv kev laus ua rau cov khoom siv hnub ci etching tswj tau qhov tseeb thiab ruaj khov rau lub sijhawm ntev. Piv txwv li, ib lub tuam txhab photovoltaic siv cov khoom siv etching nruab nrog lub hauv paus granite. Tom qab ua haujlwm tas mus li rau 15 xyoo, qhov tseeb ntawm cov khoom siv tseem tuaj yeem tswj tau hauv ± 0.05 hli, uas yuav luag zoo ib yam li qhov tseeb thaum cov khoom siv tau muab tso rau hauv kev siv thawj zaug. Piv nrog cov khoom siv siv cov hauv paus khoom siv ib txwm muaj, lub voj voog txij nkawm tau ntev dua 2 txog 3 zaug, lub neej kev pabcuam ntawm cov khoom siv tau zoo dua, thiab ntau cov nqi hloov khoom siv thiab kev txij nkawm tau txuag rau cov lag luam.
Kev ruaj khov ntawm kev ua haujlwm lav pab kev lag luam photovoltaic txo cov nqi thiab ua kom muaj txiaj ntsig zoo dua
Qhov kev tiv thaiv corrosion thiab cov khoom tiv thaiv kev laus ntawm lub hauv paus granite muab kev ruaj khov thiab txhim khu kev qha kev ua tau zoo rau cov khoom siv hnub ci etching. Kev ua haujlwm ruaj khov ntawm cov khoom siv txhais tau tias kev ua haujlwm ntau dua thiab qis dua qhov seem. Piv txwv li, ib txoj kab ntau lawm nrog lub peev xwm txhua xyoo ntawm 500MW ntawm cov photovoltaic cells. Cov khoom siv etching nrog lub hauv paus granite tuaj yeem txo lub sijhawm tsis ua haujlwm rau kev saib xyuas los ntawm kev xeb thiab kev laus ntawm cov khoom siv los ntawm kwv yees li 100 teev txhua xyoo, thiab nce tus nqi ntawm cov photovoltaic cell modules tsim los ntawm kwv yees li 2 lab yuan. Lub caij no, vim yog cov txheej txheem etching ruaj khov dua, cov khoom lag luam tau nce ntxiv 2 txog 3 feem pua, txo cov nqi tsim khoom ntxiv.

Nyob rau hauv keeb kwm yav dhau los ntawm kev lag luam photovoltaic hnub ci nrhiav kev sib npaug ntawm lub grid thiab txo nqi thiab kev txhim kho kev ua haujlwm zoo, cov hauv paus granite, nrog lawv cov khoom zoo heev ntawm kev tiv thaiv corrosion thiab tiv thaiv kev laus, tau dhau los ua qhov tseem ceeb rau kev txhim kho kev ua tau zoo thiab txo cov nqi ntawm cov khoom siv hnub ci etching. Nws tsis tsuas yog muab kev lees paub zoo rau kev tsim cov khoom zoo ntawm cov hlwb photovoltaic, tab sis kuj pab txhawb rau kev txhim kho kev lag luam photovoltaic tag nrho.
