Pakadali pano, chifukwa cha chitukuko champhamvu cha makampani opanga ma solar photovoltaic, magwiridwe antchito ndi kukhazikika kwa zida zopangira ma solar etching zimagwira ntchito yofunika kwambiri popanga ma cell a photovoltaic ogwira ntchito kwambiri. Maziko a granite, omwe ali ndi mphamvu zotsutsa dzimbiri komanso zoletsa kukalamba, akhala gawo lofunika kwambiri la zida zopangira ma solar etching.
Pewani dzimbiri la asidi ndi alkali ndipo tetezani kuyera kwa njira yocheka
Pa nthawi yogwiritsa ntchito solar etching, zinthu zowononga kwambiri monga hydrofluoric acid ndi nitric acid zimagwiritsidwa ntchito, zomwe zimakhudza kwambiri zigawo za zida. Zitsulo wamba kapena zinthu zina zimakhala ndi dzimbiri pambuyo poti zakhudzana ndi mankhwala otere kwa nthawi yayitali. Izi sizimangoipitsa yankho loboola komanso zimakhudza kulondola ndi kukhazikika kwa zida.
Granite imapangidwa makamaka ndi mchere monga quartz ndi feldspar, ndipo mphamvu zake za mankhwala zimakhala zokhazikika kwambiri. Ikayang'anizana ndi chilengedwe champhamvu cha asidi ndi alkali panthawi yocheka, maziko a granite amatha kukana dzimbiri. Malinga ndi deta yochokera ku mabungwe oyesera akatswiri, maziko a granite akamizidwa mu yankho la 20% la hydrofluoric acid kwa maola 24, makulidwe a dzimbiri pamwamba pake ndi 0.001mm yokha, zomwe zimakhala zochepa kwambiri. Kukana kwabwino kwambiri kwa dzimbiri kumeneku kumatsimikizira kuti kuyera kwa yankho locheka sikudzakhudzidwa ndi dzimbiri la maziko panthawi yogwiritsa ntchito zida zocheka kwa nthawi yayitali, motero kumatsimikizira kukhazikika ndi kusinthasintha kwa njira yocheka ndikukweza kuchuluka kwa zokolola za maselo a photovoltaic.
Ili ndi mphamvu yabwino kwambiri yolimbana ndi ukalamba ndipo imatha kukulitsa moyo wa zida
Pakupanga zida zoyeretsera za dzuwa, sizimangofunika kupirira kuwonongeka kwa mankhwala, komanso zimakumana ndi kusintha kwa kutentha pafupipafupi komanso kugwedezeka kwa makina. Zipangizo wamba, zomwe zimakhudzidwa ndi kutentha kwa nthawi yayitali komanso kufupika kwa kutentha komanso kupsinjika kwa makina, zimakhala ndi mavuto monga ukalamba ndi kusintha kwa zinthu, zomwe zimapangitsa kuti zida zisamayende bwino komanso kufunika kosintha zida zonse pasadakhale.
Granite ili ndi kapangidwe ka mkati kolimba komanso kofanana, ndipo makhiristo ake amchere amalumikizana kwambiri. Munthawi yogwiritsidwa ntchito bwino, ngakhale patatha zaka makumi angapo, mawonekedwe enieni a maziko a granite sasintha kwambiri. Kagwiridwe kake koletsa kukalamba kamathandiza kuti zida zokoka ndi dzuwa zisunge kulondola kwambiri komanso kukhazikika kwa nthawi yayitali. Mwachitsanzo, kampani ina ya photovoltaic idagwiritsa ntchito zida zokoka zokhala ndi maziko a granite. Pambuyo pogwira ntchito mosalekeza kwa zaka 15, kulondola kwa malo a zidazo kumatha kusungidwa mkati mwa ±0.05mm, zomwe zinali zofanana ndi kulondola kwa zidazo pamene zidazo zidayamba kugwiritsidwa ntchito. Poyerekeza ndi zida zogwiritsa ntchito maziko wamba, nthawi yokonza imakulitsidwa ndi nthawi ziwiri mpaka zitatu, nthawi yogwiritsira ntchito zidazo imakwera kwambiri, ndipo ndalama zambiri zosinthira ndi kukonza zida zimasungidwa m'mabizinesi.
Chitsimikizo chokhazikika cha magwiridwe antchito chimathandiza makampani opanga ma photovoltaic kuchepetsa ndalama ndikuwonjezera magwiridwe antchito
Kukana dzimbiri ndi mphamvu zoletsa kukalamba kwa maziko a granite kumapereka chitsimikizo chokhazikika komanso chodalirika cha magwiridwe antchito a zida zomangira dzuwa. Kugwira ntchito bwino kwa zida zokhazikika kumatanthauza kuti ntchito yabwino kwambiri yopangira ndi kuchepetsa kuchuluka kwa zinyalala. Mwachitsanzo, tengerani mzere wopanga wokhala ndi mphamvu ya 500MW ya maselo a photovoltaic pachaka. Zipangizo zomangira zokhala ndi maziko a granite zitha kuchepetsa nthawi yogwira ntchito yokonza yomwe imayambitsidwa ndi dzimbiri ndi kukalamba kwa zida ndi maola pafupifupi 100 pachaka, ndikuwonjezera mtengo wa ma module a maselo a photovoltaic opangidwa ndi pafupifupi 2 miliyoni yuan. Pakadali pano, chifukwa cha njira yokhazikika yomangira, kuchuluka kwa zokolola zazinthu kwawonjezeka ndi maperesenti awiri mpaka atatu, zomwe zikuchepetsanso mtengo wopangira.
Popeza makampani opanga magetsi a dzuwa amagwiritsa ntchito mphamvu ya dzuwa kuti akwaniritse bwino ntchito yawo, kuchepetsa ndalama komanso kukonza bwino ntchito yawo, maziko a granite, omwe ali ndi mphamvu zabwino zopewera dzimbiri komanso kuletsa kukalamba, akhala njira yothandiza kwambiri popititsa patsogolo magwiridwe antchito komanso kuchepetsa ndalama zogwiritsira ntchito zipangizo zopangira magetsi a dzuwa. Sikuti zimangopereka chitsimikizo cholimba cha kupanga magetsi a dzuwa, komanso zimathandiza kuti makampani onse opanga magetsi a dzuwa azitha kupanga magetsi okhazikika.
