Electrolytic Copper Foil Daim Ntawv Thov Kev Lag Luam:

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

Cov Txheej Txheem Tsim Khoom ntawm Electrolytic Copper Foil:

Txawm hais tias cov lus qhia thiab cov khoom ntawm cov ntawv ci tooj liab electrolytic tuaj yeem sib txawv nrog txhua tus neeg tsim khoom, cov txheej txheem tseem zoo ib yam. Feem ntau, txhua tus neeg tsim khoom ntawv ci yaj cov tooj liab electrolytic lossis cov hlau tooj liab pov tseg, nrog tib qhov purity electrolytic tooj liab siv ua cov khoom siv raw, hauv sulfuric acid los tsim cov kua dej ntawm tooj liab sulfate. Tom qab ntawd, los ntawm kev siv cov hlau dov ua cathode, cov hlau tooj liab yog electrodeposited rau ntawm qhov chaw ntawm cathodic roller tas li los ntawm electrolytic reaction. Nws yog peeled los ntawm cathodic roller tas li tib lub sijhawm. Cov txheej txheem no hu ua cov ntawv ci tsim thiab electrolysis txheej txheem. Sab stripped (sab du) ntawm cathode yog qhov pom ntawm qhov chaw ntawm laminated board lossis PCB, thiab sab rov qab (feem ntau hu ua sab ntxhib) yog qhov uas raug rau ntau qhov kev kho qhov chaw thiab yog bonded nrog resin hauv PCB. Cov ntawv ci tooj liab ob sab yog tsim los ntawm kev tswj cov koob tshuaj ntawm cov organic additives hauv electrolyte hauv cov txheej txheem ntawm kev tsim cov ntawv ci tooj liab rau lithium roj teeb.

Thaum lub sijhawm electrolysis, cov cations hauv electrolyte tsiv mus rau cathode, thiab raug txo qis tom qab tau txais cov electrons ntawm cathode. Cov anions raug oxidized tom qab tsiv mus rau anode thiab poob cov electrons. Ob lub electrodes txuas nrog hauv cov kua tooj liab sulfate nrog tam sim no ncaj qha. Tom qab ntawd, nws yuav pom tias tooj liab thiab hydrogen raug sib cais ntawm 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 kho qhov chaw cathode, txheej tooj liab uas tso rau ntawm cathode tuaj yeem tev tawm, kom tau txais qee qhov tuab ntawm daim ntawv tooj liab. Daim ntawv tooj liab uas muaj qee yam haujlwm hu ua ntawv ci tooj liab.
