Electrolytic Copper Foil'S Industrial Application:

Monga imodzi mwa zipangizo zofunika makampani amagetsi, electrolytic mkuwa zojambulazo zimagwiritsa ntchito kupanga kusindikizidwa dera bolodi (PCB), mabatire lifiyamu-ion, chimagwiritsidwa ntchito zipangizo kunyumba, kulankhulana, kompyuta (3C), ndi makampani mphamvu zatsopano. M'zaka zaposachedwa, zofunikira zowonjezereka komanso zatsopano zimafunikira zojambula zamkuwa ndi chitukuko cha teknoloji ya 5G ndi makampani a batri a lithiamu. Chojambula chotsika kwambiri (VLP) chamkuwa cha 5G, ndi zojambulazo zopyapyala kwambiri za batri ya lithiamu zimayang'anira njira yatsopano yopangira ukadaulo wazojambula zamkuwa.

Electrolytic Copper Foil'S Manufacturing process:

Ngakhale mafotokozedwe ndi katundu wa zojambula zamkuwa za electrolytic zimatha kusiyanasiyana ndi wopanga aliyense, njirayo imakhala yofanana. Nthawi zambiri, onse opanga zojambulazo amasungunula waya wamkuwa wa electrolytic kapena waya wamkuwa, wokhala ndi mkuwa womwewo wa electrolytic womwe umagwiritsidwa ntchito ngati zopangira, mu sulfuric acid kuti apange njira yamadzi yamkuwa ya sulfate. Kenako, kutenga zitsulo wodzigudubuza monga cathode, zitsulo mkuwa ndi electrodeposited padziko cathodic wodzigudubuza mosalekeza mwa anachita electrolytic. Imapukutidwa kuchokera ku cathodic roller mosalekeza nthawi yomweyo. Njirayi imadziwika kuti kupanga zojambulazo komanso njira ya electrolysis. Mbali yovulidwa (mbali yosalala) kuchokera ku cathode ndi yomwe imawoneka pamwamba pa bolodi la laminated kapena PCB, ndipo mbali yakumbuyo (yomwe imadziwika kuti mbali yowopsya) ndiyo yomwe imayang'aniridwa ndi chithandizo chamankhwala angapo ndipo imakhala omangidwa ndi utomoni mu PCB. Chojambula chamkuwa chokhala ndi mbali ziwiri chimapangidwa poyang'anira mlingo wa zowonjezera zowonjezera mu electrolyte popanga zojambula zamkuwa za batri ya lithiamu.

Panthawi ya electrolysis, ma cations mu electrolyte amasamukira ku cathode, ndipo amachepetsedwa atapeza ma electron pa cathode. Ma anions ndi okosijeni atasamukira ku anode ndi kutaya ma electron. Ma elekitirodi awiri olumikizidwa mu mkuwa sulphate njira ndi mwachindunji panopa. Ndiye, zidzapezeka kuti mkuwa ndi haidrojeni zimalekanitsidwa pa cathode. Zomwe zimachitika ndi izi:

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

Pambuyo pa chithandizo cha cathode pamwamba, mkuwa wosanjikiza womwe umayikidwa pa cathode ukhoza kuchotsedwa, kuti upeze makulidwe ena a pepala lamkuwa. Pepala lamkuwa lomwe lili ndi ntchito zina limatchedwa zojambulazo zamkuwa.
