Granite base: Woyang'anira kukana kwa corrosion ndi anti-kukalamba pazida zoyatsira dzuwa.

Pakalipano, ndi chitukuko champhamvu cha mafakitale a solar photovoltaic, magwiridwe antchito ndi kukhazikika kwa zida zowunikira dzuwa zimathandizira kwambiri kupanga ma cell a photovoltaic apamwamba kwambiri. Maziko a granite, omwe ali ndi mphamvu zolimbana ndi dzimbiri komanso anti-kukalamba, akhala chinthu chofunikira kwambiri pazida zoyatsira dzuwa.

Pewani asidi amphamvu ndi dzimbiri za alkali ndikuteteza kuyera kwa njira yotsekera
Panthawi yopangira dzuwa, ma reagents owopsa kwambiri monga hydrofluoric acid ndi nitric acid amagwiritsidwa ntchito, omwe amawononga kwambiri zigawo za zida. Zitsulo wamba kapena zinthu zina zapansi sachedwa dzimbiri ndi dzimbiri pambuyo yaitali kukhudzana ndi mankhwala zinthu. Izi sizimangoyipitsa yankho la etching komanso zimakhudzanso kulondola komanso kukhazikika kwa zida.

Granite imapangidwa makamaka ndi mchere monga quartz ndi feldspar, ndipo mankhwala ake ndi okhazikika kwambiri. Mukayang'anizana ndi malo amphamvu a asidi ndi alkali pakupanga ma etching, maziko a granite amatha kukana dzimbiri. Malingana ndi deta yochokera ku mabungwe oyesa akatswiri, pamene maziko a granite amizidwa mu 20% hydrofluoric acid solution kwa maola 24, makulidwe a corrosion pamwamba ndi 0.001mm okha, omwe ndi osafunika. Izi zabwino kwambiri dzimbiri kukana amaonetsetsa kuti chiyero cha etching njira sadzakhudzidwa ndi dzimbiri m'munsi pa ntchito yaitali etching zipangizo, potero zimatsimikizira bata ndi kugwirizana kwa etching ndondomeko ndi kusintha mlingo zokolola za maselo photovoltaic.
Ili ndi magwiridwe antchito abwino kwambiri oletsa kukalamba ndipo imatha kuwonjezera moyo wautumiki wa zida
Panthawi yopanga zida zopangira dzuwa, sizimangofunika kupirira kukokoloka kwa ma reagents amankhwala, komanso zimasintha pafupipafupi kutentha komanso kugwedezeka kwamakina. Zida wamba, pansi pa zotsatira za nthawi yaitali za kuwonjezereka kwa kutentha ndi kuchepetsedwa ndi kupsinjika kwa makina, zimakhala zovuta kwambiri monga kukalamba ndi kusinthika, zomwe zimapangitsa kuchepa kwa zipangizo zolondola komanso ngakhale kufunika kosintha zigawo kapena makina onse pasadakhale.

Granite ili ndi mawonekedwe amkati amkati, ndipo makristasi ake amchere amalumikizana kwambiri. Pansi pakugwiritsa ntchito bwino, ngakhale patatha zaka makumi angapo, mawonekedwe amtundu wa granite sasintha kwambiri. Kuchita kwake koletsa kukalamba kumathandizira zida zopangira ma solar kuti zikhalebe zolondola komanso zokhazikika kwa nthawi yayitali. Mwachitsanzo, bizinesi ina ya photovoltaic idagwiritsa ntchito zida zomangira zomwe zili ndi maziko a granite. Pambuyo pogwira ntchito mosalekeza kwa zaka 15, kulondola kwa malo kwa zida zikanatha kusungidwa mkati mwa ± 0.05mm, zomwe zinali pafupifupi zofanana ndi zolondola pomwe zida zidayamba kugwiritsidwa ntchito. Poyerekeza ndi zida zomwe zimagwiritsa ntchito zoyambira wamba, kuwongolera kumakulitsidwa ndi 2 mpaka 3, moyo wautumiki wa zidazo umakhala wabwino kwambiri, ndipo ndalama zambiri zosinthira zida ndi kukonza zimasungidwa kumabizinesi.
Chitsimikizo chokhazikika cha ntchito chimathandizira makampani a photovoltaic kuchepetsa ndalama ndikuwonjezera mphamvu
Kukana kwa dzimbiri komanso zotsutsana ndi ukalamba za maziko a granite zimapereka chitsimikizo chokhazikika komanso chodalirika cha zida zowunikira dzuwa. Kukhazikika kwa zida kumatanthauza kuchita bwino kwambiri komanso kutsika kwa zotsalira. Tengani mzere wopanga ndi mphamvu yapachaka ya 500MW ya maselo a photovoltaic monga chitsanzo. Zida za etching zokhala ndi maziko a granite zimatha kuchepetsa nthawi yokhazikika yokonza chifukwa cha kuwonongeka kwa zida ndi ukalamba pafupifupi maola 100 chaka chilichonse, ndikuwonjezera mtengo wa ma cell a photovoltaic opangidwa ndi pafupifupi 2 miliyoni yuan. Pakadali pano, chifukwa chokhazikika chokhazikika, zokolola zawonjezeka ndi 2 mpaka 3 peresenti, ndikuchepetsanso mtengo wopanga.

Pansi pamakampani opanga ma solar photovoltaic kufunafuna kulinganiza kwa gridi ndikuchepetsa mtengo komanso kukonza bwino, zoyambira za granite, zokhala ndi mphamvu zabwino kwambiri zokana dzimbiri komanso zoletsa kukalamba, zakhala kiyi yopititsa patsogolo magwiridwe antchito ndikuchepetsa mtengo wa zida zoyatsira dzuwa. Sizimangopereka chitsimikizo cholimba cha kupanga kwapamwamba kwambiri kwa maselo a photovoltaic, komanso kumathandizira pa chitukuko chokhazikika cha mafakitale onse a photovoltaic.
