He pō'ai ola ka Aluminum i hiki ke ho'ohālikelike i nā metala'ē a'e.He pale ʻino ia a hiki ke hana hou ʻia, e koi ana i kahi hapa o ka ikehu i hoʻohana ʻia e hana i ka metala mua.
Hoʻolilo kēia i ka alumini i mea maikaʻi loa - hana hou ʻia a hoʻoponopono hou ʻia e hoʻokō i nā pono a me nā pilikia o nā manawa like ʻole a me nā huahana.
kaulahao waiwai alumini
1. ʻO ka ʻeli ʻana i ka Bauxite
Hoʻomaka ka hana alumini me ka bauxite maka, aia ka 15-25% alumini a loaʻa ka hapa nui ma ke kāʻei a puni ka equator.Aia ma kahi o 29 biliona tonnes o ka bauxite i ʻike ʻia a ma ke ʻano o ka unuhi ʻana i kēia manawa, ʻoi aku kēia mau mea mālama iā mākou ma mua o 100 mau makahiki.Eia nō naʻe, nui nā kumuwaiwai i ʻike ʻole ʻia e hiki ke hoʻonui i kēlā i 250-340 mau makahiki.
2. Hoʻomaʻemaʻe alumina
Ke hoʻohana nei i ke kaʻina hana Bayer, lawe ʻia ka alumina (aluminium oxide) mai ka bauxite i loko o kahi mea hoʻoheheʻe.Hoʻohana ʻia ka alumina no ka hana ʻana i ka metala mua ma ka ratio o 2:1 (2 tone alumina = 1 tone alumina).
3. ʻO ka hana alumini mua
Hoʻopaʻa ʻia ka atom alumina i ka alumina i ka oxygen a pono e wāwahi ʻia e ka electrolysis e hana i ka metala alumini.Hana ʻia kēia ma nā laina hana nui a he kaʻina hana ikaika e koi ana i ka nui o ka uila.ʻO ka hoʻohana ʻana i ka mana hou a me ka hoʻomaikaʻi mau ʻana i kā mākou hana hana he ala koʻikoʻi ia e hoʻokō ai i kā mākou pahuhopu o ka lilo ʻana i carbon neutral i kahi hiʻohiʻona ola e 2020.
4. Ka hana alumini
Hāʻawi ʻo Hydro i ka mākeke me ka ʻoi aku o 3 miliona tonnes o nā huahana casthouse aluminika i kēlā me kēia makahiki, e hoʻolilo iā mākou i mea hoʻolako alakaʻi o ka extrusion ingot, sheet ingot, foundry alloys a me ka alumini maʻemaʻe kiʻekiʻe me ka honua.ʻO ka hoʻohana maʻamau o ka alumini mua he extruding, ʻōwili a hoʻolei ʻia:
4.1 Aluminum extruding
Hiki i ka Extrusion ke hana i ka alumini i loko o nā ʻano like ʻole e hiki ke noʻonoʻo ʻia me ka hoʻohana ʻana i nā kiʻi i hana ʻia a i hana ʻia paha.
4.2 Aluminum kawili
ʻO ka pahu alumini āu e hoʻohana ai i kāu lumi kuke he kumu hoʻohālike maikaʻi ia o kahi huahana alumini ʻōwili.Hāʻawi ʻia i kona malleability loa, hiki ke ʻōwili ʻia ka alumini mai 60 knm a 2 mm a hana hou ʻia i loko o ka foil e like me ka 0.006 mm a hiki ʻole i ka māmā, ka ʻala a me ka ʻono.
4.3 Aluminum hoolei ana
ʻO ka hoʻokumu ʻana i kahi huila me kekahi metala ʻē aʻe e hoʻololi i nā waiwai o ka alumini, e hoʻohui i ka ikaika, ka nani a me ka ductility.ʻO kā mākou huahana casthouse, e like me extrusion ingots, sheet ingots, foundry alloys, wire rods a me ka alumini maʻemaʻe kiʻekiʻe, hoʻohana ʻia i ka automotive, ka lawe ʻana, nā hale, ka hoʻoili wela, nā uila a me nā mokulele.
5. Hana hou
Hoʻohana hou ʻia ka aluminika i ka 5% o ka ikehu e pono ai no ka hana ʻana i ka metala mua.Eia kekahi, ʻaʻole e pōʻino ka alumini mai ka hana hou ʻana a ma kahi o 75% o nā alumini a pau i hana ʻia e hoʻohana mau ʻia ana.ʻO kā mākou pahuhopu e ulu wikiwiki aʻe ma mua o ka mākeke i ka hana hou ʻana a lawe i kahi kūlana kiʻekiʻe ma ka ʻāpana recycling o ke kaulahao waiwai alumini, e hoʻihoʻi hou ana i 1 miliona mau tone o ka alumini i hoʻohaumia ʻia a ma hope o ka mea kūʻai aku i kēlā me kēia makahiki.
