He mea keleawe lahilahi loa ke keleawe foil. Hiki ke hoʻokaʻawale ʻia ma ke kaʻina hana i ʻelua ʻano: ʻōwili (RA) keleawe a me electrolytic (ED) keleawe. He maikaʻi ka uila a me ka thermal conductivity ʻo Copper foil, a loaʻa iā ia ka waiwai o ka pale ʻana i nā hōʻailona uila a me ka magnetic. Hoʻohana nui ʻia ka foil keleawe i ka hana ʻana i nā ʻāpana uila pololei. Me ka holomua o ka hana ʻenehana hou, ʻo ke koi ʻana i nā huahana uila ʻoi aku ka lahilahi, māmā, liʻiliʻi a ʻoi aku ka lawe ʻana i ka nui o nā noi no ka foil keleawe.
Ua kapa ʻia ka pahu keleawe i ʻōwili ʻia ʻo RA copper foil. He mea keleawe ia i hana ʻia e ka ʻōwili kino. Ma muli o kāna kaʻina hana, ʻo RA copper foil kahi ʻano spherical i loko. A hiki ke hoʻololi ʻia i ka huhū palupalu a paʻakikī me ka hoʻohana ʻana i ke kaʻina hana annealing. Hoʻohana ʻia ʻo RA copper foil i ka hana ʻana i nā huahana uila kiʻekiʻe, ʻoi aku ka nui o nā mea e koi ai i kahi pae o ka maʻalahi o ka mea.
Ua kapa ʻia ʻo Electrolytic copper foil e like me ED copper foil. He mea keleawe keleawe ia i hana ʻia e ke kaʻina hoʻoheheʻe kemika. Ma muli o ke ʻano o ke kaʻina hana, electrolytic copper foil he columnar structure i loko. ʻO ke kaʻina hana o ka electrolytic copper foil he mea maʻalahi a hoʻohana ʻia i nā huahana e koi ana i ka nui o nā kaʻina hana maʻalahi, e like me nā papa kaapuni a me nā electrodes ʻino lithium.
Loaʻa nā pono a me nā hemahema o ka RA copper foil a me ka electrolytic copper foil i ka hahai ʻana i nā hiʻohiʻona:
ʻOi aku ka maʻemaʻe o RA copper foil ma ke ʻano o ke keleawe;
ʻOi aku ka maikaʻi o ka hana maʻamau o RA copper foil ma mua o ka electrolytic copper foil ma ke ʻano o nā waiwai kino;
He ʻokoʻa liʻiliʻi ma waena o nā ʻano ʻelua o ke keleawe keleawe ma ke ʻano o nā waiwai kemika;
Ma ke ʻano o ke kumukūʻai, ʻoi aku ka maʻalahi o ka ED copper foil i ka hoʻohua nui ʻana ma muli o kāna kaʻina hana maʻalahi a ʻoi aku ka liʻiliʻi ma mua o ka pepa keleawe calendered.
ʻO ka maʻamau, hoʻohana ʻia ʻo RA copper foil i ka hoʻomaka ʻana o ka hana ʻana i nā huahana, akā i ka ulu ʻana o ke kaʻina hana hana, e lawe ʻia ʻo ED copper foil i mea e hōʻemi ai i nā kumukūʻai.
He maikaʻi ka uila a me ka thermal conductivity ʻo Copper foil, a he mau mea pale maikaʻi nō hoʻi ia no nā hōʻailona uila a me ka magnetic. No laila, hoʻohana pinepine ʻia ʻo ia ma ke ʻano he ala no ka hoʻokele uila a i ʻole ka wela i nā huahana uila a me nā huahana uila, a i ʻole he mea pale no kekahi mau mea uila. Ma muli o ka ʻike a me nā waiwai kino o ke keleawe a me ke keleawe keleawe, hoʻohana ʻia lākou i ka hoʻonaninani hale a me nā ʻoihana ʻē aʻe.
ʻO ka mea maka no ka copper foil he keleawe maʻemaʻe, akā aia nā mea maka i nā moku'āina likeʻole ma muli o nā kaʻina hana likeʻole. Hana ʻia ka pahu keleawe i ʻōwili ʻia mai nā ʻāpana keleawe electrolytic cathode i hoʻoheheʻe ʻia a laila ʻōwili ʻia; Pono ka Electrolytic copper foil e hoʻokomo i nā mea maka i loko o ka sulfuric acid solution no ka hoʻoheheʻe ʻana e like me ka ʻauʻau keleawe, a laila ʻoi aku ka makemake e hoʻohana i nā mea maka e like me ke kī keleawe a i ʻole ke kelepona keleawe no ka hoʻoheheʻe maikaʻi ʻana me ka sulfuric acid.
He ʻeleʻele loa nā iona keleawe i ka lewa a hiki ke hana maʻalahi me nā ion oxygen i ka lewa e hana i ka ʻokikene keleawe. Hana mākou i ka ʻili o ka copper foil me ka lumi wela anti-oxidation i ka wā o ke kaʻina hana, akā hoʻopaneʻe wale kēia i ka manawa i hoʻopaʻa ʻia ai ka pahu keleawe. No laila, ʻōlelo ʻia e hoʻohana koke i ka foil keleawe ma hope o ka wehe ʻana. A e mālama i ka pepa keleawe i hoʻohana ʻole ʻia ma kahi maloʻo a me ka māmā māmā ma kahi mamao mai nā kinoea. ʻO ka mahana mālama mālama ʻia no ke keleawe keleawe ma kahi o 25 degere Celsius a ʻaʻole pono ka haʻahaʻa ma mua o 70%.
ʻO Copper foil ʻaʻole ia he mea conductive wale nō, akā ʻo ka ʻoihana ʻoihana ʻoi aku ka maikaʻi loa i loaʻa. ʻOi aku ka maikaʻi o ka uila a me ka wela ma mua o nā mea metala maʻamau.
ʻO ka lipine copper foil ka mea maʻamau ma ka ʻaoʻao keleawe, a hiki ke hana ʻia ka ʻaoʻao adhesive ma ke kau ʻana i ka pauka conductive i ka adhesive. No laila, pono ʻoe e hōʻoia inā pono ʻoe i ka lipine copper foil conductive ʻaoʻao hoʻokahi a i ʻole ʻelua ʻaoʻao conductive copper foil tape i ka manawa kūʻai.
Hiki ke hoʻoneʻe ʻia ka pahu keleawe me ka oxidation liʻiliʻi o ka ʻili me ka puna wai. Inā lōʻihi ka oxidation a i ʻole ka nui o ka oxidation, pono e wehe ʻia ma ka hoʻomaʻemaʻe ʻana me ka solution sulfuric acid.
Loaʻa iā CIVEN Metal kahi lipine keleawe keleawe kūikawā no ke aniani ʻeleʻele i maʻalahi loa e hoʻohana.
Ma ke kumumanaʻo, ʻae; akā naʻe, no ka mea, ʻaʻole i mālama ʻia ka hoʻoheheʻe ʻana o nā mea i loko o kahi ʻenekini a me nā mea hana like ʻole e hoʻohana i nā ʻano wela like ʻole a me nā kaʻina hana, i hui pū ʻia me nā ʻokoʻa o nā kaiapuni hana, hiki ke hoʻohui ʻia nā mea ʻokoʻa i loko o ka mea i ka wā e hana ai. ʻO ka hopena, ʻoiai inā like ke ʻano o ka mea hana, hiki ke loaʻa nā ʻokoʻa kala i nā mea mai nā mea hana like ʻole.
I kekahi manawa, ʻoiai no nā mea hoʻomaʻemaʻe keleawe kiʻekiʻe, hiki ke ʻokoʻa ke kala o ka ʻili o nā pahu keleawe i hana ʻia e nā mea hana like ʻole i ka pouli. Manaʻo kekahi poʻe he ʻoi aku ka maʻemaʻe o nā pahu keleawe ʻulaʻula ʻeleʻele. Eia nō naʻe, ʻaʻole pololei kēia no ka mea, ma waho aʻe o ka ʻike keleawe, hiki i ka maʻalahi o ka ʻili o ka pepa keleawe ke hoʻoulu i nā ʻokoʻa kala i ʻike ʻia e ka maka kanaka. No ka laʻana, ʻoi aku ka maikaʻi o ka noʻonoʻo ʻana o ka ʻili keleawe me ka maʻalahi o ka ʻili, e ʻoi aku ka māmā o ka waihoʻoluʻu o ka ʻili, a i kekahi manawa keʻokeʻo. ʻO kaʻoiaʻiʻo, he mea maʻamau kēia no ka foil keleawe me ka maʻalahi maikaʻi, e hōʻike ana he maʻalahi kaʻili a he haʻahaʻa haʻahaʻa.
Hana ʻia ka pahu keleawe electrolytic me ka hoʻohana ʻana i ke ʻano kemika, no laila ʻaʻohe aila ka ʻili o ka huahana. ʻO ka hoʻohālikelike, hana ʻia ka foil keleawe i ʻōwili ʻia me ka hoʻohana ʻana i ke ʻano ʻōwili kino, a i ka wā o ka hana ʻana, hiki ke noho mau ka aila lubricating mechanical mai nā wili ma ka ʻili a i loko o ka huahana i hoʻopau ʻia. No laila, pono ka hoʻomaʻemaʻe ʻana i ka ʻili a me ka degreasing e wehe i nā koena aila. Inā ʻaʻole wehe ʻia kēia mau koena, hiki iā lākou ke hoʻopilikia i ka pale ʻili o ka ʻili o ka huahana i hoʻopau ʻia. ʻOi aku i ka wā o ka lamination kiʻekiʻe, hiki i nā koena aila o loko ke kahe i ka ʻili.
ʻOi aku ke kiʻekiʻe o ka maʻalahi o ka ʻili keleawe, ʻoi aku ka kiʻekiʻe o ka noʻonoʻo ʻana, hiki ke ʻike ʻia ke keʻokeʻo i ka maka ʻōlohelohe. ʻOi aku ka maikaʻi ʻoi aku ka maikaʻi o ka ili a me ka wela o ka mea. Inā makemakeʻia kahi kaʻina hana hoʻopili ma hope, pono e koho i nā mea hoʻopili wai e like me ka hiki. ʻO nā uhi ʻaila, ma muli o ko lākou ʻano nui o ka molecular surface, e ʻoi aku ka ʻili.
Ma hope o ke kaʻina hana annealing, hoʻomaikaʻi ʻia ka maʻalahi a me ka plasticity o ka mea keleawe foil, ʻoiai e hoʻemi ʻia kona resistivity, e hoʻonui ana i kona conductivity uila. Eia nō naʻe, ʻoi aku ka maʻalahi o ka mea annealed i nā ʻōpala a me nā niho ke hoʻopili ʻia me nā mea paʻakikī. Hoʻohui ʻia, hiki i nā haʻalulu liʻiliʻi i ka wā o ka hana ʻana a me ka lawe ʻana i ke kaʻina hana hiki ke hoʻololi i ka mea a hana i ka embossing. No laila, pono ka mālama ʻana i ka wā o ka hana ʻana a me ka hana ʻana.
No ka mea, ʻaʻole i loaʻa i nā kūlana honua o kēia manawa nā ʻano hoʻāʻo kūpono a kūlike a me nā maʻamau no nā mea me ka mānoanoa o ka liʻiliʻi ma mua o 0.2mm, paʻakikī ka hoʻohana ʻana i nā koina paʻakikī kuʻuna e wehewehe i ke kūlana palupalu a paʻakikī paha o ka foil keleawe.
