Inkqubo Yokuvelisa Nokuvelisa I-Copper Foil

I-copper foil, eli phepha lobhedu elibonakala lilula kakhulu, linenkqubo yokwenziwa ebuthathaka kakhulu neyinkimbinkimbi. Le nkqubo ibandakanya ikakhulu ukukhutshelwa nokucocwa kobhedu, ukwenziwa kwe-copper foil, kunye namanyathelo okwenziwa emva kokucubungula.

Inyathelo lokuqala kukukhupha nokucoca ubhedu. Ngokwedatha evela kwi-United States Geological Survey (USGS), imveliso yehlabathi ye-copper ore ifikelele kwiitoni ezingama-20 ezigidi ngo-2021 (USGS, 2021). Emva kokukhupha i-copper ore, ngamanyathelo afana nokutyumza, ukugaya, kunye nokuflotha, i-copper concentrate enomxholo wobhedu omalunga ne-30% ingafunyanwa. Ezi copper concentrate emva koko zidlula kwinkqubo yokucocwa, kubandakanya ukunyibilikisa, ukucocwa kwe-converter, kunye ne-electrolysis, ekugqibeleni ivelisa i-electrolytic copper enobumsulwa obufikelela kwi-99.99%.

Okulandelayo kuza inkqubo yokwenziwa kwefoyile yobhedu, enokwahlulwa ibe ziintlobo ezimbini ngokuxhomekeke kwindlela yokwenziwa: ifoyile yobhedu ye-electrolytic kunye nefoyile yobhedu eqengqiweyo.

Ifoyile yekopolo ye-electrolytic yenziwa ngenkqubo ye-electrolytic. Kwiseli ye-electrolytic, i-anode yekopolo iyanyibilika kancinci kancinci phantsi kwesenzo se-electrolyte, kwaye ii-ion zekopolo, eziqhutywa yi-current, ziya kwi-cathode kwaye zenze iidiphozithi zekopolo kumphezulu we-cathode. Ubukhulu befoyile yekopolo ye-electrolytic buhlala buqala kwi-5 ukuya kwi-200 micrometers, ezinokulawulwa ngokuchanekileyo ngokweemfuno zobuchwepheshe bebhodi yesekethe eprintiweyo (PCB) (Yu, 1988).

Ifoyile yobhedu eqengqiweyo, kwelinye icala, yenziwa ngoomatshini. Iqala kwishiti yobhedu enobukhulu obuziimilimitha ezininzi, iyancitshiswa kancinci ngokuyiqengqa, ekugqibeleni ivelise ifoyile yobhedu enobukhulu obukwinqanaba le-micrometer (Coombs Jr., 2007). Olu hlobo lwefoyile yobhedu lunomphezulu othambileyo kunefoyile yobhedu ye-electrolytic, kodwa inkqubo yokuvelisa kwayo itya amandla amaninzi.

Emva kokuba i-copper foil yenziwe, idla ngokufuna ukuba iqhutywe emva kokucutshungulwa, kuquka ukucutshungulwa, ukucutshungulwa komphezulu, njl.njl., ukuphucula ukusebenza kwayo. Umzekelo, ukucutshungulwa kunokuphucula ukuguguleka kunye nokuqina kwe-copper foil, ngelixa unyango lomphezulu (njengokucutshungulwa okanye ukugqunywa) lunokuphucula ukumelana nokugqwala kunye nokunamathela kwe-copper foil.

Ngamafutshane, nangona inkqubo yokuvelisa nokuvelisa i-copper foil inzima, imveliso yemveliso inefuthe elikhulu kubomi bethu banamhlanje. Oku kukubonakaliswa kwenkqubela phambili kwezobuchwepheshe, okuguqula izixhobo zendalo zibe ziimveliso zobugcisa obuphezulu ngokusebenzisa iindlela ezichanekileyo zokuvelisa.

Nangona kunjalo, inkqubo yokwenza i-copper foil ikwazisa nemingeni ethile, kuquka ukusetyenziswa kwamandla, impembelelo kwindalo esingqongileyo, njl. Ngokwengxelo, ukuveliswa kwetoni enye yobhedu kufuna malunga ne-220GJ yamandla, kwaye kuvelisa iitoni eziyi-2.2 zokukhutshwa kwe-carbon dioxide (Northey et al., 2014). Ke ngoko, kufuneka sifumane iindlela ezisebenzayo nezinobuhlobo nokusingqongileyo zokuvelisa i-copper foil.

Esinye isisombululo esinokwenzeka kukusebenzisa ubhedu oluphinda lusetyenziswe ukuvelisa i-copper foil. Kubikwa ukuba ukusetyenziswa kwamandla okuvelisa ubhedu oluphinda lusetyenziswe yi-20% kuphela yaleyo yobhedu oluphambili, kwaye kunciphisa ukusetyenziswa kwezixhobo ze-copper ore (UNEP, 2011). Ukongeza, ngokuqhubela phambili kwetekhnoloji, singaphuhlisa iindlela zokwenza i-copper foil ezisebenzayo nezisindisa amandla, nto leyo enciphisa ngakumbi impembelelo yazo kwindalo esingqongileyo.

Ukuqukumbela, inkqubo yokuvelisa nokuvelisa i-copper foil yintsimi yetekhnoloji egcwele imingeni namathuba. Nangona senze inkqubela phambili enkulu, kusekho umsebenzi omninzi ekufuneka wenziwe ukuqinisekisa ukuba i-copper foil inokuhlangabezana neemfuno zethu zemihla ngemihla ngelixa ikhusela okusingqongileyo.
