Electrolytic Copper Foil'S Industrial Application:

Raws li ib qho ntawm cov ntaub ntawv tseem ceeb ntawm kev lag luam hluav taws xob, electrolytic tooj liab ntawv ci feem ntau yog siv los tsim cov ntawv luam tawm Circuit Board (PCB), lithium-ion roj teeb, dav siv hauv cov khoom siv hauv tsev, kev sib txuas lus, kev suav (3C), thiab kev lag luam hluav taws xob tshiab. Nyob rau hauv xyoo tas los no, yuav tsum nruj dua thiab tshiab yuav tsum tau rau cov ntawv ci tooj liab nrog kev txhim kho 5G thev naus laus zis thiab kev lag luam roj teeb lithium. Tsawg heev profile (VLP) tooj liab ntawv ci rau 5G, thiab ultra-thin tooj liab ntawv ci rau lithium roj teeb dominate tus tshiab txoj kev loj hlob ntawm tooj liab ntawv ci technology.

Electrolytic Copper Foil'S Manufacturing Txheej txheem:

Txawm hais tias cov lus qhia tshwj xeeb thiab cov khoom ntawm electrolytic tooj liab ntawv ci tuaj yeem sib txawv nrog txhua lub chaw tsim khoom, cov txheej txheem tseem tseem zoo ib yam. Feem ntau, txhua lub tuam txhab cov ntawv ci dissolve electrolytic tooj liab los yog khib nyiab tooj liab hlau, nrog tib purity electrolytic tooj liab siv los ua raw khoom, nyob rau hauv sulfuric acid los tsim ib tug aqueous tov ntawm tooj liab sulfate. Tom qab ntawd, los ntawm kev noj cov hlau rau cov menyuam ua cov cathode, cov hlau tooj liab yog electrodeposited rau saum npoo ntawm cov menyuam cathodic tsis tu ncua los ntawm cov tshuaj tiv thaiv electrolytic. Nws yog tev tawm ntawm cov menyuam cathodic tsis tu ncua tib lub sijhawm. Cov txheej txheem no yog hu ua cov ntawv ci tsim thiab electrolysis txheej txheem. Lub stripped sab (sab du) los ntawm lub cathode yog ib qho pom ntawm lub laminated board los yog PCB, thiab sab nraub qaum (feem ntau hu ua sab ntxhib) yog ib qho uas yuav tsum tau ua raws li kev kho deg thiab yog txuas nrog resin hauv PCB. Lub ob sab tooj liab ntawv ci yog tsim los ntawm kev tswj cov koob tshuaj ntawm cov organic additives nyob rau hauv electrolyte nyob rau hauv tus txheej txheem ntawm ua tooj liab foil rau lithium roj teeb.

Thaum lub sij hawm electrolysis, cov cations nyob rau hauv lub electrolyte migrate mus rau lub cathode, thiab yuav txo tau tom qab tau txais electrons ntawm lub cathode. Cov anions yog oxidized tom qab tsiv mus rau lub anode thiab poob electrons. Ob lub electrodes txuas nrog hauv cov tshuaj tooj liab sulphate nrog ncaj qha tam sim no. Tom qab ntawd, nws yuav pom tias tooj liab thiab hydrogen tau sib cais ntawm lub cathode. Cov tshuaj tiv thaiv yog raws li nram no:

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

Tom qab kev kho mob ntawm cathode nto, tooj liab txheej tso rau ntawm cathode tuaj yeem raug tev tawm, kom tau txais qee qhov tuab ntawm daim ntawv tooj liab. Daim ntawv tooj liab nrog qee yam haujlwm yog hu ua tooj liab ntawv.
