Isicelo Sezimboni se-Electrolytic Copper Foil:

Njengenye yezinto eziyisisekelo embonini ye-elekthronikhi, ucwecwe lwethusi lwe-electrolytic lusetshenziswa ikakhulukazi ukwenza ibhodi lesifunda eliphrintiwe (PCB), amabhethri e-lithium-ion, asetshenziswa kakhulu ezintweni zikagesi zasendlini, ukuxhumana, ikhompyutha (3C), kanye nemboni yamandla amasha. Eminyakeni yamuva, izidingo eziqinile nezintsha ziyadingeka ku-foil yethusi ngokuthuthukiswa kobuchwepheshe be-5G kanye nemboni yebhethri ye-lithium. I-foil yethusi ephansi kakhulu (i-VLP) ye-5G, kanye ne-ultra-thin copper foil yebhethri ye-lithium ibusa indlela entsha yokuthuthukiswa kobuchwepheshe be-copper foil.

Inqubo Yokukhiqiza Ye-Electrolytic Copper Foil:

Nakuba ukucaciswa kanye nezakhiwo ze-electrolytic copper foil zingahluka kumkhiqizi ngamunye, inqubo ihlala ifana. Ngokuvamile, bonke abakhiqizi be-foil bancibilikisa i-electrolytic copper noma i-waste copper wire, ne-copper ehlanzekile ye-electrolytic efanayo esetshenziswa njengempahla eluhlaza, ku-sulfuric acid ukukhiqiza isisombululo esinamanzi se-copper sulfate. Ngemuva kwalokho, ngokuthatha i-roller yensimbi njenge-cathode, ithusi lensimbi lifakwa e-electrodeposited ebusweni berola ye-cathodic ngokuqhubekayo ngokusabela kwe-electrolytic. Ihlutshiwe kusukela ku-cathodic roller ngokuqhubekayo ngesikhathi esifanayo. Le nqubo yaziwa ngokuthi inqubo yokukhiqiza i-foil kanye ne-electrolysis. Uhlangothi oluhlutshiwe (uhlangothi olubushelelezi) olusuka ku-cathode yilolo olubonakala phezu kwebhodi elamiwe noma i-PCB, kanti uhlangothi olungemuva (olwaziwa ngokuthi uhlangothi olumaholoholo) yilo olungaphansi kochungechunge lwezindlela zokwelapha ezingaphezulu futhi ihlanganiswe ne-resin ku-PCB. I-foil yethusi enezinhlangothi ezimbili yenziwa ngokulawula umthamo wezithasiselo eziphilayo ku-electrolyte ohlelweni lokukhiqiza ucwecwe lwethusi lwebhethri ye-lithium.

Ngesikhathi se-electrolysis, ama-cations ku-electrolyte athuthela ku-cathode, futhi ayancipha ngemva kokuthola ama-electron ku-cathode. Ama-anion akhishwa nge-oxidized ngemva kokuthuthela ku-anode nokulahlekelwa ama-electron. Ama-electrode amabili axhunywe kwisisombululo se-sulphate yethusi nge-current eqondile. Khona-ke, kuzotholakala ukuthi ithusi ne-hydrogen zihlukaniswa ku-cathode. Ukusabela kungokulandelayo:

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

Ngemuva kokwelashwa kwendawo ye-cathode, ungqimba lwethusi olufakwe ku-cathode lungasuswa, ukuze kutholakale ubukhulu obuthile beshidi lethusi. Ishidi lethusi elinemisebenzi ethile libizwa nge-copper foil.
