Electrolytic Copper Foil's Industrial Application:

Ma ke ʻano he kumu kumu o ka ʻoihana uila, hoʻohana nui ʻia ka electrolytic copper foil no ka hana ʻana i ka papa kaapuni paʻi (PCB), nā pākahi lithium-ion, hoʻohana nui ʻia i nā mea hana home, kamaʻilio, ka helu (3C), a me ka ʻoihana ikehu hou. I nā makahiki i hala iho nei, koi ʻia nā koi hou aʻe no ka copper foil me ka hoʻomohala ʻana o ka ʻenehana 5G a me ka ʻoihana pākaukau lithium. ʻO ka pahu keleawe haʻahaʻa haʻahaʻa loa (VLP) no 5G, a me ka pahu keleawe ultra-thin no ka pā lithium e hoʻomalu i ke kuhikuhi hoʻomohala hou o ka ʻenehana keleawe.

Electrolytic Copper Foil's Manufacturing Process:

ʻOiai hiki ke ʻokoʻa nā kikoʻī a me nā waiwai o ka electrolytic copper foil i kēlā me kēia mea hana, e mau ana ke kaʻina hana. ʻO ka maʻamau, hoʻopau nā mea hana foil a pau i ke keleawe electrolytic a i ʻole ka uea keleawe, me ke keleawe electrolytic maʻemaʻe like i hoʻohana ʻia e like me ka mea maka, i loko o ka sulfuric acid e hana ai i kahi wai wai o ke keleawe sulfate. Ma hope o kēlā, ma ka lawe ʻana i ka wili metala ma ke ʻano he cathode, ua hoʻopaʻa ʻia ke keleawe keleawe ma ka ʻili o ka roller cathodic e hoʻomau mau ana ma o ka hopena electrolytic. Ua ʻili ʻia mai ka ʻōwili cathodic i ka manawa like. ʻIke ʻia kēia kaʻina hana ʻo ka hana ʻana i ka foil a me ke kaʻina hana electrolysis. ʻO ka ʻaoʻao i kāʻili ʻia (ʻaoʻao maʻemaʻe) mai ka cathode ka mea i ʻike ʻia ma ka ʻili o ka papa laminated a i ʻole PCB, a ʻo ka ʻaoʻao hope (ʻike mau ʻia ʻo ka ʻaoʻao ʻoʻoleʻa) ʻo ia ka mea i kau ʻia i ke ʻano o ka mālama ʻana i ka ʻili. i hoʻopaʻa ʻia me ka resin i ka PCB. Hoʻokumu ʻia ka pahu keleawe ʻelua ʻaoʻao ma o ka hoʻomalu ʻana i ka nui o nā mea hoʻohui organik i ka electrolyte i ke kaʻina hana o ke keleawe keleawe no ka pā lithium.

I ka wā electrolysis, neʻe nā cations i ka electrolyte i ka cathode, a hoʻemi ʻia ma hope o ka loaʻa ʻana o nā electrons ma ka cathode. Hoʻopili ʻia nā anion ma hope o ka neʻe ʻana i ka anode a nalowale nā ​​electrons. Hoʻohui ʻia ʻelua mau electrodes i loko o ka solution copper sulphate me ke au pololei. A laila, e ʻike ʻia ua hoʻokaʻawale ʻia ke keleawe a me ka hydrogen ma ka cathode. Penei ka hopena:

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

Ma hope o ka mālama ʻana i ka ʻili cathode, hiki ke ʻoki ʻia ka ʻāpana keleawe i waiho ʻia ma ka cathode, e loaʻa ai kahi mānoanoa o ka pepa keleawe. ʻO ka pepa keleawe me kekahi mau hana i kapa ʻia ʻo copper foil.
