Isicelo soShishino lweFoyile ye-Electrolytic Copper:

Njengenye yezinto ezisisiseko kwishishini lombane, ifoyile yobhedu ye-electrolytic isetyenziswa ikakhulu ukwenza ibhodi yesekethe eprintiweyo (PCB), iibhetri ze-lithium-ion, ezisetyenziswa kakhulu kwizixhobo zasekhaya, unxibelelwano, ikhompyuter (3C), kunye neshishini elitsha lamandla. Kwiminyaka yakutshanje, iimfuno ezingqongqo kunye nezitsha ziyafuneka kwifoyile yobhedu kunye nophuhliso lwetekhnoloji ye-5G kunye noshishino lwebhetri ye-lithium. Iprofayili ephantsi kakhulu (i-VLP) ye-copper foil ye-5G, kunye ne-ultra-thin copper foil ye-lithium ibhetri ilawula indlela entsha yophuhliso lobuchwepheshe be-copper foil.

Inkqubo yokuVelisa i-Electrolytic Copper Foil:

Nangona iinkcukacha kunye neempawu zefoyile yobhedu ye-electrolytic zinokuhluka kumenzi ngamnye, inkqubo ihlala ifana. Ngokuqhelekileyo, bonke abavelisi be-foil banyibilikisa i-electrolytic copper okanye i-waste copper wire, kunye ne-copper ye-electrolytic efanayo ecocekileyo esetyenziswa njengempahla ekrwada, kwi-asidi ye-sulfuric ukuvelisa isisombululo esimanzi se-copper sulfate. Emva koko, ngokuthatha i-roller yensimbi njenge-cathode, i-metallic copper i-electrodeposited phezu kwendawo ye-cathodic roller ngokuqhubekayo ngokuphendula kwe-electrolytic. Ihlanjululwe kwi-cathodic roller ngokuqhubekayo ngexesha elifanayo. Le nkqubo yaziwa ngokuba ifoyile yokuvelisa kunye nenkqubo electrolysis. Icala elikhutshiweyo (icala eligudileyo) ukusuka kwi-cathode lilo elibonakalayo kumphezulu webhodi elaminethiweyo okanye i-PCB, kunye necala elingasemva (eliqhelekileyo elaziwa ngokuba licala elirhabaxa) lilo elixhomekeke kuthotho lwezonyango zomphezulu kwaye lidityaniswe nentlaka kwiPCB. Ifoyile yobhedu enamacala amabini yenziwa ngokulawula umthamo wezongezo zendalo kwi-electrolyte kwinkqubo yokuvelisa ifoyile yobhedu yebhetri ye-lithium.

Ngexesha le-electrolysis, i-cations kwi-electrolyte ifudukela kwi-cathode, kwaye iyancipha emva kokufumana i-electron kwi-cathode. I-anion i-oxidized emva kokufudukela kwi-anode kunye nokulahlekelwa kwee-electron. Ama-electrode amabini axhunyiwe kwisisombululo se-sulphate yethusi kunye nombane othe ngqo. Emva koko, kuya kufunyanwa ukuba ubhedu kunye ne-hydrogen zihlukaniswe kwi-cathode. Impendulo yile ilandelayo:

ICathode: Cu2+ +2e → Cu 2H+ +2e → H2↑
I-Anode: 4OH- -4e → 2H2O + O2↑
2SO42-+2H2O -4e → 2H2SO4 + O2↑

Emva kokunyangwa kwendawo ye-cathode, i-copper layer efakwe kwi-cathode inokuhlanjululwa, ukufumana ubuninzi bephepha lobhedu. Iphepha lobhedu elinemisebenzi ethile libizwa ngokuba yi-copper foil.
