Ka hoʻohana ʻana i nā lāʻau keleawe a me nā lāʻau keleawe

Hoohana i na Kooko keleawe
1. Hiki ke hoʻohana ʻia no nā ʻano kikoʻī hohonu a me nā ʻāpana kūlou, e like me nā pine, rivets, washers, nuts, conduits, barometers, screens, radiator parts, etc.
2. Loaʻa iā ia ka hana mīkini maikaʻi loa, ka plasticity maikaʻi loa i ka moku wela, ka plasticity i ʻae ʻia i ke kūlana anuanu, ka machinability maikaʻi, ka maʻalahi o ka wili a me ke kuʻi ʻana, a me ka pale ʻana i ka corrosion.He ʻano keleawe maʻamau ia i hoʻohana mau ʻia.

Ka hoʻohana ʻana i nā lāʻau keleawe
1.1.ʻOi aku ka laulā o ka hoʻohana ʻana i nā koʻokoʻo keleawe ʻulaʻula ma mua o ka hao maʻemaʻe.I kēlā me kēia makahiki, hoʻomaʻemaʻe ʻia ka 50% o ke keleawe i ke keleawe maʻemaʻe, i hoʻohana ʻia i ka ʻoihana uila.ʻO ke keleawe ʻulaʻula i ʻōlelo ʻia ma ʻaneʻi he mea maʻemaʻe loa, me ka ʻike keleawe ma mua o 99.95%.ʻO ka liʻiliʻi loa o nā haumia, ʻoi aku ka phosphorus, arsenic, aluminika, a me nā mea ʻē aʻe, e hoʻemi nui i ka conductivity o ke keleawe.
2. Oxygen i loko o ke keleawe (he wahi liʻiliʻi o ka oxygen e hui maʻalahi i ka hoʻoheheʻe keleawe) he hopena nui i ka conductivity uila.ʻO ke keleawe i hoʻohana ʻia i ka ʻoihana uila ma ke ʻano he keleawe ʻole oxygen.Eia kekahi, ʻo nā mea haumia e like me ke alakaʻi, antimony, a me ka bismuth e hana i nā kristal keleawe i hiki ʻole ke hui pū, e hoʻoulu ai i ka brittleness wela a pili i ka hana ʻana o ke keleawe maʻemaʻe.Hoʻomaʻemaʻe ʻia kēia keleawe maʻemaʻe kiʻekiʻe e ka electrolysis: me ka hoʻohana ʻana i ke keleawe haumia (ʻo ia hoʻi, blister copper) ma ke anode, keleawe maʻemaʻe e like me ka cathode, a me ka solution copper sulfate e like me ka electrolyte.Ke hala ke au, hehee malie ke keleawe maemae ole ma ka anode, a kahe malie ke keleawe maemae ma ka cathode.ʻO ke keleawe i loaʻa ma kēiaʻano;hiki i ka maemae ke hiki i 99.99%.
