Pehea i hana ʻia ai ka alumini?
E kiʻi i nā mea koʻikoʻi ma ka huakaʻi alumini mai ka bauxite, ma o ka hana ʻana, hoʻohana a me ka hana hou ʻana.
Mea maka
Mea wili bauxite
Hoʻomaka ka hana ʻana o ka alumini me ka bauxite maka, kahi pālolo e like me ka ʻano lepo i loaʻa i loko o ke kāʻei a puni ka equator.ʻEli ʻia ka bauxite mai kahi mau mika ma lalo o ka lepo.
alumina
Lawe ʻia ka alumina, a i ʻole alumini oxide, mai ka bauxite ma o ka hoʻomaʻemaʻe ʻana.
Kaʻina hoʻomaʻemaʻe
Hoʻokaʻawale ʻia ka alumina mai ka bauxite me ka hoʻohana ʻana i kahi hopena wela o ka soda caustic a me ka lime.
alumina maʻemaʻe
Hoʻokaʻawale ʻia ka alumina mai ka bauxite me ka hoʻohana ʻana i kahi hopena wela o ka soda caustic a me ka lime.
Holomua
Kaʻina hoʻomaʻemaʻe
ʻO ke kū aʻe ka mea kanu metala.Maʻaneʻi, hoʻololiʻia ka alumina i hoʻomaʻemaʻeʻia i alumini.
ʻEkolu mau mea maka e pono ai no ka hana ʻana i ka alumini, ka alumini oxide, ka uila a me ke kalapona.
Holo ka uila ma waena o kahi cathode maikaʻi ʻole a me kahi anode maikaʻi, i hana ʻia ʻelua me ke kalapona.Hoʻopili ka anode me ka oxygen i loko o ka alumina a hana i CO2.
ʻO ka hopena he alumini wai, hiki ke paʻi ʻia i kēia manawa mai nā cell.
Nā huahana
Hoʻolei ʻia ka alumini wai i loko o nā extrusion ingots, sheet ingots a i ʻole foundry alloys, ma muli o ka mea e hoʻohana ʻia ai.
Hoʻololi ʻia ka alumini i nā huahana like ʻole.
Extrusion
I ke kaʻina hana extrusion, ua wela ka alumini ingot a kaomi ʻia ma o kahi mea hana i kapa ʻia he make.
ʻO ke kaʻina hana
ʻO ka ʻenehana extrusion he aneane palena ʻole no ka hoʻolālā ʻana a hāʻawi i nā manawa noi he nui.
Kaʻa ʻana
Hoʻohana ʻia nā pepa ingots no ka hana ʻana i nā huahana i ʻōwili ʻia, e like me nā papa, ka ʻōpala a me ka foil.
ʻO ke kaʻina hana
He ductile loa ka alumini.Hiki ke ʻōwili ʻia ka Foil mai 60 knm a 2-6 mm, a hiki ke ʻano lahilahi ka huahana foil hope e like me ka 0.006 mm.ʻAʻole ia e ʻae i ka mālamalama, ka ʻala a me ka ʻono i loko a i waho.
Nā mea hoʻoheheʻe kumu mua
Hoʻolei ʻia nā ʻāpana alumini i nā ʻano like ʻole.E hoʻoheheʻe hou ʻia ka metala a hana ʻia, no ka laʻana, nā rim huila a i ʻole nā ʻāpana kaʻa ʻē aʻe.
Hana hou
Pono ka 5 pakeneka o ka ikehu i hoʻohana ʻia no ka hana ʻana i ka alumini hou.
Hiki ke hana hou ʻia ka alumini me ka 100 pakeneka pono.I nā huaʻōlelo ʻē aʻe, ʻaʻohe o nā ʻano kūlohelohe alumini i nalowale i ke kaʻina hana hou.
Ua like paha ka huahana hana hou me ka huahana kumu, a i ʻole hiki ke lilo i mea ʻokoʻa loa.ʻO nā mokulele, nā kaʻa, nā paikikala, nā waʻa, nā kamepiula, nā mea pono o ka hale, nā uea a me nā kini he kumu no ka hana hou ʻana.
He aha ka mea hiki ke hana i ka alumini no ʻoe?
Hāʻawi mākou i kahi ākea o nā huahana alumini a me nā hoʻonā.E ʻimi i kāu huahana a e hoʻokaʻaʻike mai iā mākou e kūkākūkā i kāu papahana alumini me kā mākou poʻe loea.
