Isisekelo se-Granite: Umnakekeli wokumelana nokugqwala kanye nokunqanda ukuguga kwemishini yokufaka amandla elanga.

Njengamanje, ngokuthuthukiswa okunamandla kwemboni ye-solar photovoltaic, ukusebenza nokuzinza kwemishini yokufaka ilanga kudlala indima ebalulekile ekukhiqizeni amaseli e-photovoltaic asebenza kahle kakhulu. Isisekelo se-granite, esinokumelana nokugqwala okuvelele kanye nezindawo zokulwa nokuguga, sesiyingxenye ebalulekile yemishini yokushisa ilanga.

Melana ne-asidi eqinile nokugqwala kwe-alkali futhi uvikele ubumsulwa benqubo yokufaka
Phakathi nenqubo yokufaka i-solar etching, kusetshenziswa ama-reagents amakhemikhali agqwala kakhulu njenge-hydrofluoric acid ne-nitric acid, anomthelela omkhulu wokugqwala ezingxenyeni zemishini. Izisekelo zensimbi ezivamile noma ezinye izinto zijwayele ukugqwala nokugqwala ngemva kokuxhumana isikhathi eside nalawo makhemikhali. Lokhu akugcini nje ngokungcolisa isisombululo se-etching kodwa futhi kuthinta ukunemba nokuzinza kwemishini.

I-Granite yakhiwe ngokuyinhloko ngamaminerali afana ne-quartz ne-feldspar, futhi izakhiwo zayo zamakhemikhali zizinzile ngokwedlulele. Uma ubhekene nemvelo ye-asidi eqinile ne-alkali kunqubo yokuhlanganisa, isisekelo segwadle singamelana ngempumelelo nokugqwala. Ngokwemininingwane evela ezikhungweni zokuhlola ezichwepheshile, lapho isisekelo segwadle sicwiliswa kusixazululo se-hydrofluoric acid esingu-20% amahora angu-24, ukugqwala okungaphezulu kungu-0.001mm kuphela, okucishe kungabi nalutho. Lokhu kumelana nokugqwala okuhle kakhulu kuqinisekisa ukuthi ukuhlanzeka kwesisombululo se-etching ngeke kuthinteke ukugqwala kwesisekelo ngesikhathi sokusetshenziswa kwesikhathi eside kwemishini yokufaka, ngaleyo ndlela kuqinisekisa ukuzinza nokuvumelana kwenqubo yokufaka kanye nokwenza ngcono izinga lokukhiqiza lamaseli e-photovoltaic.
Inokusebenza okuhle kakhulu kokulwa nokuguga futhi inganweba impilo yesevisi yemishini
Ngesikhathi sokukhiqizwa kwemishini yokufaka i-solar, akufanele nje kuphela ibekezelele ukuguguleka kwama-reagents amakhemikhali, kodwa futhi ihlangabezane nezinguquko ezivamile zokushisa kanye nokudlidliza kwemishini. Izinto ezivamile, ngaphansi komphumela wesikhathi eside wokunwetshwa okushisayo nokuncipha kanye nokucindezeleka kwemishini, zijwayele izinkinga ezifana nokuguga nokuguqulwa, okuholela ekwehleni kokunemba kwemishini ngisho nesidingo sokushintsha izingxenye noma umshini wonke kusengaphambili.

I-Granite inesakhiwo sangaphakathi esiminyene nesifanayo, futhi amakristalu ayo amaminerali ahlanganiswe eduze komunye nomunye. Ngaphansi kwezimo ezivamile zokusetshenziswa, ngisho nangemva kwamashumi eminyaka ambalwa, izici ezibonakalayo zesisekelo se-granite ngeke zishintshe kakhulu. Ukusebenza kwayo okulwa nokuguga kwenza umshini wokushisa ilanga ugcine ukunemba okuphezulu nokuzinza isikhathi eside. Isibonelo, inkampani ethile ye-photovoltaic yasebenzisa imishini yokuhlanganisa efakwe isisekelo se-granite. Ngemva kokusebenza okuqhubekayo iminyaka eyi-15, ukunemba kokuma kwendawo okokusebenza kwakusakwazi ukugcinwa ngaphakathi kuka-±0.05mm, okwakucishe kufane nokunemba lapho okokusebenza kuqala ukusetshenziswa. Uma kuqhathaniswa nemishini esebenzisa izinto eziyisisekelo ezijwayelekile, umjikelezo wokunakekela unwetshwa izikhathi ezi-2 kuye kwezi-3, impilo yesevisi yemishini ithuthukiswa kakhulu, futhi inani elikhulu lezindleko zokushintshwa kwemishini kanye nokugcinwa kwazo zilondolozelwa amabhizinisi.
Isiqinisekiso sokusebenza esizinzile sisiza imboni ye-photovoltaic ukunciphisa izindleko nokwandisa ukusebenza kahle
Ukumelana nokugqwala kanye nezakhiwo zokulwa nokuguga zesisekelo se-granite kunikeza iziqinisekiso ezizinzile nezithembekile zokusebenza kwemishini yokufaka ilanga. Ukusebenza kwemishini okuzinzile kusho ukusebenza kahle okuphezulu kokukhiqiza kanye nezinga eliphansi le-scrap. Thatha umugqa wokukhiqiza onamandla wonyaka we-500MW wamaseli e-photovoltaic njengesibonelo. Imishini yokufaka i-etching enesisekelo se-granite inganciphisa isikhathi sokuphumula sokulungiswa okubangelwa ukugqwala kwemishini nokuguga cishe ngamahora angu-100 unyaka ngamunye, futhi ikhulise inani lamamojula e-photovoltaic cell akhiqizwa cishe ama-yuan ayizigidi ezingu-2. Khonamanjalo, ngenxa yenqubo yokubhala ezinzile, izinga lomkhiqizo likhuphuke ngamaphesenti angu-2 kuya kwangu-3, ​​okuqhubeka nokunciphisa izindleko zokukhiqiza.

Ngaphansi kokwasemuva kwemboni ye-solar photovoltaic yokuphishekela ukulingana kwegridi nokunciphisa izindleko kanye nokwenza ngcono ukusebenza kahle, izisekelo zegwadle, ezinezici zazo ezinhle kakhulu zokumelana nokugqwala kanye nokulwa nokuguga, zibe ukhiye wokuthuthukisa ukusebenza nokunciphisa izindleko zemishini yokuhlanganisa ilanga. Akugcini nje ukunikeza isiqinisekiso esiqinile sokukhiqizwa kwekhwalithi ephezulu yamaseli e-photovoltaic, kodwa futhi kunomthelela ekuthuthukisweni okusimeme kwemboni yonke ye-photovoltaic.
