Aluminum, he mea maʻamau i ko mākou ola i kēlā me kēia lā, mai nā kini soda a i nā ʻāpana mokulele, hoʻoulu pinepine i ka ʻike: he metala maoli ka alumini? He ʻae ʻae ka pane. ʻAʻole metala wale nō ka alumini; he mea hoʻohiwahiwa me nā waiwai kūʻokoʻa a me ka nui o nā noi. E luʻu kākou i ka mea e hana ai ka alumini i metala a me ke kumu he mea nui ia.

He aha ka wehewehe ʻana i kahi metala?

No ka hoʻomaopopo ʻana i ke kumu i hoʻokaʻawale ʻia ai ka alumini ma ke ʻano he metala, pono kakou e nana i na ano e wehewehe ana i na metala:

1. ʻO ka hoʻokō: ʻO nā metala nā mea hoʻokele maikaʻi o ka uila a me ka wela.
2. ʻōlinolino: He ʻano ʻālohilohi ko nā metala ke hoʻoliʻiliʻi ʻia.
3. Malleability a me Ductility: Hiki ke ʻoki ʻia nā metala i ʻāpana lahilahi a i ʻole e huki ʻia i loko o nā uwea me ka haki ʻole.
4. ʻO ka mānoanoa a me ka ikaika: Loaʻa i nā metala ke kiʻekiʻe a me ka ikaika.
5. Hoʻohuehue: Hiki i nā metala ke nalowale i nā electrons i nā hopena kemika, hana ana i na iona maikai.

Aluminum: He Metala ma ka wehewehe

Aluminum (hōʻailona kemika Al, helu atomika 13) kaha i keia mau pahu a pau:

1. ʻO ka hoʻokō: ʻO ka alumini ka mea lawe uila maikaʻi, ʻo ia ke kumu i hoʻohana nui ʻia ai i nā laina uila uila. ʻO kona hoʻoili wela hoʻi he mea kūpono ia no nā mea wela a me nā mea kuke.
2. ʻōlinolino: Ke poni, he ʻālohilohi ka alumini, hiʻona ʻālohilohi, ʻoluʻolu aesthetically no nā mea hoʻonaninani like ʻole.
3. Malleability a me Ductility: ʻO ka alumini ka malleable a me ka ductile, ʻae ʻia e hana ʻia i nā ʻano like ʻole a me nā hale. He mea koʻikoʻi kēia waiwai i nā kaʻina hana.
4. ʻO ka mānoanoa a me ka ikaika: He māmā ka alumini i ka hoʻohālikelike ʻia me nā metala ʻē aʻe e like me ke kila, akā, loaʻa iā ia kahi ratio ikaika-a-kaumaha maikaʻi. He mea waiwai kēia i nā ʻoihana kahi mea koʻikoʻi ka hōʻemi ʻana i ke kaumaha, e like me ka aerospace a me nā ʻāpana automotive.
5. Hoʻohuehue: Hoʻopili ka Aluminum me ka oxygen e hana i kahi ʻāpana oxide pale, ka mea e pale ai i ka poino hou aku. Hoʻonui kēia waiwai i kona lōʻihi a kūpono ia no ka hoʻohana ʻana i waho.

Nā Pono Kūikawā o Aluminum

ʻOiai kaʻana like ʻana o ka alumini i nā waiwai me nā metala ʻē aʻe, ua kaena pū kekahi i kekahi mau hiʻohiʻona:

• Haʻahaʻa haʻahaʻa: ʻO ka nui o ka alumini ma kahi o hoʻokahi hapakolu o ke kila, ʻoi aku ka māmā. ʻOi aku ka maikaʻi o kēia waiwai i nā noi i mea nui ka hoʻemi ʻana i ke kaumaha, e like me ka mokulele a me ka mokulele.
• Pale ʻino: ʻO ka papa oxide kūlohelohe i hana ʻia ma ka ʻili o ka alumini he mea pale pale i ka corrosion, He mea maikaʻi loa ia i ke kūkulu ʻana a me nā noi kai.
• Hoʻohana hou: ʻO ke alumini 100% hiki ke hana hou me ka nalowale ole o kona mau waiwai maoli. ʻO ka hana hou ʻana i ka alumini e mālama ai a hiki i 95% o ka ikehu e pono ai e hana i ka alumini hou mai ka aila maka, e hoʻolilo iā ia i koho pili kaiapuni.

Nā noi o ka Aluminum

Mahalo i kona mau waiwai like ʻole, Loaʻa ka alumini i nā noi ma nā ʻoihana he nui:

• Aerospace: ʻO ke ʻano māmā akā ikaika o ka alumini ka mea kūpono no nā kino mokulele a me nā ʻāpana.
• Kaʻa kaʻa: Aluminum is used in car frames, poloka engine, a me nā huila e hōʻemi i ke kaumaha a hoʻomaikaʻi i ka pono o ka wahie.
• Kūkulu: ʻO ke kūpaʻa ʻino o ka alumini a me ka ikaika o ke kūkulu ʻana i kūpono no ke kūkulu ʻana i nā facades, puka makani, a me na puka.
• Mea uila: ʻO kāna conductivity maikaʻi e hōʻoia i ka hoʻohana ʻana o ka alumini i nā uwila, pumehana, a me nā ʻāpana uila like ʻole.
• Hoʻopili ʻia: ʻO ke ʻano ʻawaʻawa ʻole o ka alumini a me ka hana hou ʻana e lilo ia i koho kaulana no ka ʻai a me ka mea inu, e like me nā kini a me nā pepa.
