Njengamanje, ngentuthuko enamandla yemboni ye-solar photovoltaic, ukusebenza kanye nokuqina kwemishini yokuqopha ilanga kudlala indima ebalulekile ekukhiqizweni kwamaseli e-photovoltaic asebenza kahle kakhulu. Isisekelo se-granite, esinokumelana nokugqwala okuvelele kanye nezakhiwo zokulwa nokuguga, sesibe yingxenye ebalulekile yemishini yokuqopha ilanga.
Melana nokugqwala okunamandla kwe-asidi kanye ne-alkali futhi uvikele ubumsulwa benqubo yokuqopha
Ngesikhathi senqubo yokugcaba ngelanga, kusetshenziswa ama-reagent amakhemikhali agcaba kakhulu njenge-hydrofluoric acid kanye ne-nitric acid, anomphumela omuhle wokugcaba ezingxenyeni zemishini. Izisekelo zensimbi noma ezinye izinto ezivamile zivame ukugcaba nokugcaba ngemva kokuxhumana isikhathi eside nezinto ezinjalo zamakhemikhali. Lokhu akugcini nje ngokungcolisa ikhambi lokugcaba kodwa futhi kuthinta ukunemba nokuzinza kwemishini.
I-granite yakhiwe kakhulu ngamaminerali afana ne-quartz ne-feldspar, futhi izakhiwo zayo zamakhemikhali zizinzile kakhulu. Uma ibhekene nendawo enamandla ye-asidi ne-alkali enqubweni yokuqopha, isisekelo se-granite singamelana ngempumelelo nokugqwala. Ngokusho kwedatha evela ezikhungweni zokuhlola zobungcweti, lapho isisekelo se-granite sicwiliswa esixazululweni se-hydrofluoric acid esingu-20% amahora angama-24, ubukhulu bokugqwala kobuso bungu-0.001mm kuphela, okuyinto ecishe ingabi nkulu kangako. Lokhu kumelana nokugqwala okuhle kuqinisekisa ukuthi ubumsulwa besisombululo sokuqopha ngeke buthinteke ukugqwala kwesisekelo ngesikhathi sokusetshenziswa kwesikhathi eside kwemishini yokuqopha, ngaleyo ndlela kuqinisekisa ukuzinza nokuvumelana kwenqubo yokuqopha nokuthuthukisa izinga lokukhiqizwa kwamaseli e-photovoltaic.
Isebenza kahle kakhulu ekulweni nokuguga futhi ingandisa impilo yesevisi yemishini
Ngesikhathi senqubo yokukhiqiza imishini yokusika yelanga, ayigcini nje ngokubekezelela ukuguguleka kwama-reagent amakhemikhali, kodwa futhi ibhekana nokushintsha kwezinga lokushisa njalo kanye nokudlidliza kwemishini. Izinto ezivamile, ngaphansi komphumela wesikhathi eside wokwanda kokushisa kanye nokufinyela kanye nokucindezeleka kwemishini, zivame ukuba nezinkinga ezifana nokuguga kanye nokuguquguquka, okuholela ekwehleni kokunemba kwemishini ngisho nesidingo sokushintsha izingxenye noma umshini wonke kusenesikhathi.
I-Granite inesakhiwo sangaphakathi esiminyene nesilinganayo, futhi amakristalu ayo amaminerali ahlanganiswe eduze. Ngaphansi kwezimo ezijwayelekile zokusetshenziswa, ngisho nangemva kwamashumi eminyaka ambalwa, izakhiwo zomzimba zesisekelo se-granite ngeke zishintshe kakhulu. Ukusebenza kwayo okulwa nokuguga kwenza imishini yokuqopha ilanga igcine ukunemba okuphezulu nokuzinza isikhathi eside. Isibonelo, ibhizinisi elithile le-photovoltaic lisebenzise imishini yokuqopha efakwe isisekelo se-granite. Ngemva kokusebenza okuqhubekayo iminyaka eyi-15, ukunemba kokubekwa kwemishini kwakusagcinwa ngaphakathi kuka-±0.05mm, okwakucishe kufane nokunemba lapho imishini isetshenziswa okokuqala. Uma kuqhathaniswa nemishini esebenzisa izisekelo zezinto ezivamile, umjikelezo wokulungisa wandiswa izikhathi ezi-2 kuya kwezi-3, impilo yesevisi yemishini ithuthukiswa kakhulu, futhi inani elikhulu lezindleko zokufaka esikhundleni nezokuyilungisa imishini zilondolozwa emabhizinisini.
Isiqinisekiso sokusebenza okuzinzile sisiza imboni ye-photovoltaic ukunciphisa izindleko nokwandisa ukusebenza kahle
Ukumelana nokugqwala kanye nezakhiwo zokulwa nokuguga zesisekelo se-granite kunikeza iziqinisekiso zokusebenza ezizinzile nezithembekile zemishini yokugqwala yelanga. Ukusebenza kwemishini ezinzile kusho ukusebenza kahle okuphezulu kokukhiqiza kanye nesilinganiso esiphansi se-scrap. Thatha umugqa wokukhiqiza onomthamo waminyaka yonke wamaseli e-photovoltaic angu-500MW njengesibonelo. Imishini yokugqwala enesisekelo se-granite inganciphisa isikhathi sokungasebenzi kokulungiswa okubangelwa ukugqwala kwemishini nokuguga cishe ngamahora ayi-100 unyaka ngamunye, futhi inyuse inani lamamojula weseli le-photovoltaic akhiqizwa cishe yi-yuan eyizigidi ezimbili. Okwamanje, ngenxa yenqubo yokugqwala ezinzile, izinga lokukhiqiza komkhiqizo likhuphuke ngamaphesenti ama-2 kuya kwangu-3, okunciphisa kakhulu izindleko zokukhiqiza.
Ngaphansi kwesizinda sokuphishekela kwemboni ye-solar photovoltaic ukulingana kwegridi kanye nokunciphisa izindleko kanye nokuthuthukiswa kokusebenza kahle, izisekelo ze-granite, ezinezimfanelo zazo ezinhle kakhulu zokumelana nokugqwala kanye nokulwa nokuguga, ziye zaba yisihluthulelo sokuthuthukisa ukusebenza kanye nokunciphisa izindleko zemishini yokusika yelanga. Akugcini nje ngokunikeza isiqinisekiso esiqinile sokukhiqizwa kwekhwalithi ephezulu kwamaseli e-photovoltaic, kodwa futhi kunegalelo ekuthuthukisweni okusimeme kwemboni yonke ye-photovoltaic.
