I-Electrolytic Copper Foil'S yoShishino lweSicelo kunye neNkqubo yokuVelisa

Isicelo soShishino lweFoil 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 nobhedu obusulungekileyo be-electrolytic obusetyenziswa njengesixhobo ekrwada, kwi-asidi ye-sulfuric ukuvelisa isisombululo esimanzi se-copper sulfate.Emva koko, ngokuthatha i-roller yensimbi njenge-cathode, i-copper ye-metallic i-electrodeposited phezu komphezulu we-cathodic roller ngokuqhubekayo ngokuphendula kwe-electrolytic.Ihlanjululwe kwi-cathodic roller ngokuqhubekayo ngexesha elifanayo.Le nkqubo yaziwa ngokuba ifoyile yokuvelisa kunye nenkqubo electrolysis.Icala elihlutyiweyo (icala eligudileyo) ukusuka kwicathode lelo libonakala kumphezulu webhodi elaminethiweyo okanye iPCB, kwaye icala elingasemva (eliqhelekileyo elaziwa ngokuba licala elirhabaxa) lelo eliphantsi koluhlu lonyango lomphezulu kwaye liphantsi koluhlu lonyango olungaphezulu idityaniswe ne-resin kwi-PCB.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.
