Kugwiritsa Ntchito Mafakitale a Electrolytic Copper Foil'S:

Monga chimodzi mwa zinthu zofunika kwambiri pamakampani amagetsi, foil yamkuwa yamagetsi imagwiritsidwa ntchito kwambiri popanga bolodi losindikizidwa (PCB), mabatire a lithiamu-ion, omwe amagwiritsidwa ntchito kwambiri pazida zapakhomo, kulumikizana, makompyuta (3C), ndi mafakitale atsopano amagetsi. M'zaka zaposachedwa, zofunikira kwambiri komanso zatsopano zimafunikira pa foil yamkuwa ndi chitukuko cha ukadaulo wa 5G ndi makampani a batire ya lithiamu. Foil yamkuwa yotsika kwambiri (VLP) ya 5G, ndi foil yamkuwa yopyapyala kwambiri ya batire ya lithiamu ndizo zomwe zimapangitsa kuti ukadaulo wa foil yamkuwa ukhale wopita patsogolo.

Njira Yopangira Foil ya Electrolytic Copper:

Ngakhale kuti kufotokozera ndi makhalidwe a electrolytic copper foil zimatha kusiyana ndi wopanga aliyense, njira yake imakhalabe yofanana. Kawirikawiri, opanga ma foil onse amasungunula electrolytic copper kapena zinyalala zamkuwa, ndi electrolytic copper yoyera yomwe imagwiritsidwa ntchito ngati zopangira, mu sulfuric acid kuti apange yankho lamadzi la copper sulfate. Pambuyo pake, potenga chitsulo chozungulira ngati cathode, mkuwa wachitsulo umayikidwa pa electrode pamwamba pa cathodic roller mosalekeza kudzera mu electrolytic reaction. Umachotsedwa kuchokera ku cathodic roller mosalekeza nthawi yomweyo. Njirayi imadziwika kuti foil producing and electrolysis process. Mbali yodulidwa (mbali yosalala) kuchokera ku cathode ndi yomwe imawonekera pamwamba pa bolodi la laminated kapena PCB, ndipo mbali yakumbuyo (yomwe imadziwika kuti rough side) ndi yomwe imathandizidwa ndi mitundu yosiyanasiyana ya pamwamba ndipo imalumikizidwa ndi resin mu PCB. Double-sided copper foil imapangidwa poyang'anira kuchuluka kwa zowonjezera zachilengedwe mu electrolyte popanga copper foil ya batri ya lithiamu.

Pa nthawi ya electrolysis, ma cation mu electrolyte amasamukira ku cathode, ndipo amachepa atatha kupeza ma electron pa cathode. Ma anion amasungunuka akasamukira ku anode ndikutaya ma electron. Ma electrode awiri amalumikizidwa mu yankho la copper sulphate ndi direct current. Kenako, zidzapezeka kuti mkuwa ndi haidrojeni zimalekanitsidwa pa cathode. Yankho lake ndi motere:

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

Pambuyo pokonza pamwamba pa cathode, wosanjikiza wa mkuwa womwe uli pa cathode ukhoza kuchotsedwa, kuti pakhale pepala la mkuwa lolimba. Pepala la mkuwa lomwe lili ndi ntchito zina limatchedwa pepala la mkuwa.
