Electrolytic Copper Foil'S Industrial Application:

Seimwe yezvinhu zvakakosha zveindasitiri yemagetsi, electrolytic copper foil inonyanya kushandiswa kugadzira yakadhindwa yedunhu bhodhi (PCB), lithium-ion mabhatiri, anoshandiswa zvakanyanya mumidziyo yemumba, kutaurirana, komputa (3C), uye indasitiri yesimba idzva. Mumakore achangopfuura, zvakanyanya kuomarara uye zvitsva zvinodiwa zvinodikanwa kune foil yemhangura nekuvandudzwa kwe5G tekinoroji uye lithium bhatiri indasitiri. Yakanyanya yakaderera mbiri (VLP) yemhangura foil ye5G, uye yakanyanya-yakatetepa yemhangura foil yelithium bhatiri inotonga nzira nyowani yekuvandudza yecopper foil tekinoroji.

Electrolytic Copper Foil'S Manufacturing process:

Kunyangwe izvo zvinotsanangurwa uye zvimiro zve electrolytic copper foil zvinogona kusiyana nemugadziri wega wega, maitiro anoramba akafanana. Kazhinji, vese vanogadzira foil vanonyungudutsa electrolytic copper kana tsvina yemhangura waya, ine kuchena kwakafanana electrolytic mhangura inoshandiswa seyakagadzirwa, mu sulfuric acid kugadzira aqueous solution yecopper sulfate. Mushure meizvozvo, nekutora simbi roller se cathode, iyo simbi yemhangura inoiswa electrodeposited pamusoro peiyo cathodic roller inoenderera kuburikidza ne electrolytic reaction. Inopepetwa kubva kune cathodic roller nguva dzose panguva imwe chete. Iyi nzira inozivikanwa seye foil kugadzira uye electrolysis process. Rutivi rwakabviswa (parutivi rwakapfava) kubva kucathode ndiro rinoonekwa pamusoro pelamineti board kana PCB, uye reseri divi (rinowanzozivikanwa seyakakasharara) ndiro rinoiswa pasi pekutevedzana kwekurapa kwepamusoro uye iri yakasungwa neresin muPCB. Iyo yakapetwa kaviri-yamativi foil yemhangura inoumbwa nekudzora dhizimusi yezve organic additives mu electrolyte mukati mekugadzira foil yemhangura ye lithium bhatiri.

Munguva ye electrolysis, cations mu electrolyte inotamira kune cathode, uye inoderedzwa mushure mekuwana maerekitironi pa cathode. Maanion anoiswa oxidized mushure mekutamira kune anode uye kurasikirwa maerekitironi. Ma electrode maviri akabatanidzwa mumhangura sulphate mhinduro ine yakananga ikozvino. Zvadaro, zvichaonekwa kuti mhangura nehydrogen zvakaparadzaniswa pane cathode. Mhinduro yacho ndeiyi:

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

Mushure mekurapwa kwenzvimbo ye cathode, mhangura yemhangura yakaiswa pane cathode inogona kupepetwa, kuti iwane humwe ukobvu hwemhangura sheet. Pepa remhangura rine mamwe mabasa rinonzi copper foil.
