Ifoyile yobhedu, eli phepha libonakala lilula kakhulu lobhedu, linenkqubo yokwenziwa ethambileyo nentsonkothileyo.Le nkqubo ikakhulu ibandakanya ukutsalwa kunye nokusulungekiswa kobhedu, ukwenziwa kwefoyile yobhedu, kunye namanyathelo asemva kokulungiswa.
Inyathelo lokuqala kukutsalwa nokusulungekiswa kobhedu.Ngokutsho kwedatha evela kwi-United States Geological Survey (USGS), imveliso yehlabathi jikelele yobhedu ifikelele kwi-20 yezigidi zeetoni kwi-2021 (USGS, 2021).Emva kokutsalwa kwentsimbi ekrwada yobhedu, ngokwamanyathelo afana nokutyumza, ukusila, kunye nokuphaphatheka, ukugxila kobhedu malunga ne-30% yomxholo wobhedu kunokufunyanwa.Oku kugxilwa kobhedu emva koko kungena kwinkqubo yokusulungekiswa, kubandakanywa ukunyibilika, ukusulungekiswa kwe-converter, kunye ne-electrolysis, ekugqibeleni ivelise ubhedu lwe-electrolytic olunobunyulu obuphezulu ukuya kuma-99.99%.
Okulandelayo kuza inkqubo yokwenziwa kwefoyile yobhedu, enokwahlulwa ibe ziindidi ezimbini ngokuxhomekeke kwindlela yokuvelisa: ifoyile yobhedu ye-electrolytic kunye nefoyile yobhedu eqengqelekisiweyo.
I-Electrolytic copper foil yenziwa ngenkqubo ye-electrolytic.Kwiseli ye-electrolytic, i-anode yethusi iyancibilika ngokuthe ngcembe phantsi kwesenzo se-electrolyte, kwaye ii-ion zethusi, eziqhutywa yi-current, zihambela kwi-cathode kwaye zenze iidiphozithi zethusi kwindawo ye-cathode.Ubuninzi be-foil yobhedu ye-electrolytic ngokuqhelekileyo busuka kwi-5 ukuya kwi-200 micrometers, enokulawulwa ngokuchanekileyo ngokweemfuno zebhodi yesekethe eprintiweyo (PCB) ubuchwepheshe (Yu, 1988).
Ifoyile yobhedu eqengqelekisiweyo, kwelinye icala, yenziwa ngoomatshini.Ukuqala kwiphepha lobhedu elineemilimitha ezininzi ubukhulu, lincitshiswa ngokuthe ngcembe ngokuqengqeleka, ekugqibeleni livelise ifoyile yobhedu enobunzima obukwinqanaba lemicrometer (Coombs Jr., 2007).Olu hlobo lwe-foil yobhedu lunomgangatho ococekileyo kune-electrolytic copper foil, kodwa inkqubo yokuvelisa idla amandla amaninzi.
Emva kokuba i-foil yobhedu yenziwe, ngokuqhelekileyo kufuneka iqhutywe emva kokulungiswa, kubandakanywa i-annealing, unyango olungaphezulu, njl., Ukuphucula ukusebenza kwayo.Umzekelo, i-annealing inokuphucula ukudumba kunye nokuqina kwefoyile yobhedu, ngelixa unyango olungaphezulu (olufana ne-oxidation okanye i-coating) lunokonyusa ukuxhathisa ukudleka kunye nokuncamathela kwefoyile yobhedu.
Isishwankathelo, nangona ukuveliswa kunye nenkqubo yokuvelisa i-foil yobhedu inzima, imveliso yemveliso inempembelelo enkulu kubomi bethu banamhlanje.Oku kubonakaliswa kwenkqubela phambili yezobuchwepheshe, ukuguqula ubutyebi bendalo kwiimveliso eziphezulu zobugcisa ngokusebenzisa iindlela ezichanekileyo zokuvelisa.
Nangona kunjalo, inkqubo yokuvelisa i-foil yobhedu nayo izisa imingeni ethile, kubandakanywa ukusetyenziswa kwamandla, impembelelo yokusingqongileyo, njl. Ngokutsho kwengxelo, ukuveliswa kwe-1 toni yobhedu kufuna malunga ne-220GJ yamandla, kwaye ivelise iitoni ze-2.2 ze-carbon dioxide emissions (Northey). et al., 2014).Ngoko ke, kufuneka sifumane iindlela ezisebenzayo kunye nezokusingqongileyo zokuvelisa i-foil yobhedu.
Esinye isisombululo esinokubakho kukusebenzisa ubhedu oluhlaziyiweyo ukuvelisa ifoyile yobhedu.Kuxelwa ukuba ukusetyenziswa kwamandla okuvelisa ubhedu oluhlaziyiweyo kuphela i-20% yeyobhedu oluphambili, kwaye kunciphisa ukusetyenziswa kwemithombo yobhedu (UNEP, 2011).Ukongeza, ngokuhambela phambili kwetekhnoloji, sinokuphuhlisa ubuchule bokwenza ifoyile yobhedu esebenzayo kunye neyonga amandla, sinciphise ngakumbi ifuthe labo lokusingqongileyo.
Ekugqibeleni, ukuveliswa kunye nenkqubo yokuvelisa i-foil yobhedu yintsimi yezobuchwepheshe egcwele imingeni kunye namathuba.Nangona senze inkqubela ebonakalayo, usemkhulu umsebenzi ekufuneka wenziwe ukuqinisekisa ukuba ifoyile yobhedu inokuhlangabezana neemfuno zethu zemihla ngemihla lo gama sikhusela okusingqongileyo.
