Copper - Nā kikoʻī, nā waiwai, nā hoʻohālikelike a me nā papa

ʻO ke keleawe ka metala kahiko loa i hoʻohana ʻia e ke kanaka.Hoʻohana ʻia ia mai ka wā prehistoric.Ua ʻeli ʻia ke keleawe ma mua o 10,000 mau makahiki me kahi pendant Copper i loaʻa i kēia lā ʻo Iraq i hoʻopaʻa ʻia i 8700BC.Ma ka makahiki 5000BC, ua hooheheeia ke keleawe mai ka Copper Oxides.Loaʻa ke keleawe ma ke ʻano metala maoli a i loko o nā minerala cuprite, malachite, azurite, chalcopyrite a me bornite.
He mea hoʻohana pinepine ia o ka hana kālā.ʻO Sulphides, oxides a me carbonates ka mea nui loa.ʻO ke keleawe a me ke keleawe kekahi o nā mea ʻenehana loea i loaʻa.ʻO ka hui pū ʻana o nā waiwai kino e like me ka ikaika, conductivity, corrosion resistance, machinability a me ductility e hana i ke keleawe kūpono no ka nui o nā noi.Hiki ke hoʻonui ʻia kēia mau waiwai me nā ʻano like ʻole o ka haku mele ʻana a me nā ʻano hana hana.

Hale Hana
ʻO ka hoʻohana hope loa no ke keleawe ma ka ʻoihana hale.I loko o ka ʻoihana kūkulu hale ākea ka hoʻohana ʻana i nā mea keleawe.ʻO nā noi e pili ana i ka ʻoihana kūkulu no ke keleawe:

Kaupaku
Hoʻopili
Pūnaehana wai ua
Pūnaehana hoʻomehana
ʻO nā paipu wai a me nā mea pono
Laina aila a me ke kinoea
Uea uila
ʻO ka ʻoihana hale ka mea kūʻai hoʻokahi nui loa o ke keleawe keleawe.ʻO ka papa inoa ma lalo iho nei ka haʻihaʻi ʻana o ka hoʻohana keleawe e ka ʻoihana i kēlā me kēia makahiki:

ʻOihana kūkulu hale - 47%
Nā huahana uila - 23%
Kaʻahele - 10%
Nā mea kūʻai aku - 11%
Nā mīkini ʻenehana - 9%

Na Hana Kalepa o ke keleawe
Aia ma kahi o 370 mau haku mele no ke keleawe keleawe.ʻO ka papa maʻamau ka C106/CW024A - ka pae wai maʻamau o ke keleawe.

ʻOi aku ka nui o ka hoʻohana ʻana i ke keleawe a me ke keleawe keleawe i kēia manawa ma mua o 18 miliona tonnes i kēlā me kēia makahiki.

Noi o ke keleawe
Hiki ke hoʻohana ʻia ke keleawe a me ke keleawe i loko o kahi ʻano o nā noi.Aia kekahi o kēia mau noi:

Nā laina hoʻoili mana
Nā polokalamu hoʻolālā
Nā lako kuke
Pākuʻi
Uea uila, uwea a me na busbar
Nā uwea conductivity kiʻekiʻe
Nā uila uila
Nā mea hoʻololi wela
Paipu hau
Pahu paipu
ʻO nā kīʻaha keleawe hoʻoluʻu wai
