Kū'ē ka alumini ma waena o nā metala ʻē aʻe me kona pōʻaiaola ola ʻole. ʻO kona pale ʻana i ka corrosion a me ka hana hou ʻana he mea kūʻokoʻa ia, no ka mea hiki ke hoʻohana hou ʻia i nā manawa he nui me ka haʻahaʻa haʻahaʻa haʻahaʻa e hoʻohālikelike ʻia i ka hana metala puʻupaʻa. Mai ka mining bauxite mua a hiki i ka hana ʻana i nā huahana maʻamau a me nā kaʻina hana hou ʻana, hoʻokumu kā mākou hui alumini paʻa piha i ka waiwai ma ka pōʻai holoʻokoʻa.

kaulahao waiwai alumini

1. ʻO ka ʻeli ʻana i ka Bauxite

ʻO ke kaʻina hana o ka aluminika mai ka hana ʻana o ka bauxite, kahi ʻaila i loaʻa ma kahi o 15-25% alumini a aia ka nui ma nā wahi a puni ka equator. I kēia manawa, ua manaʻo ʻia he 29 biliona tonnes o ka bauxite i hiki ke hoʻomau i ka ʻili ʻana no hoʻokahi haneli i kēia manawa. Eia kekahi, ʻo ka loaʻa ʻana o nā kumuwaiwai i ʻike ʻole ʻia e hōʻike ana i ka hiki ke hoʻonui i kēia manawa 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. Ka hana alumini mua

No ka hana ʻana i ka metala alumini, pono e wāwahi ʻia ka pilina paʻa ma waena o ka alumini a me ka oxygen i ka alumina ma o ka electrolysis. He kaʻina hana ikaika loa kēia i hana ʻia i nā hale hana nui, e koi ana i ka nui o ka uila. I mea e hoʻokō ai i kā mākou pahuhopu e lilo i carbon neutral mai kahi hiʻohiʻona lifecycle e 2020, he mea koʻikoʻi ia e hoʻohana i nā kumu mana hou a hoʻonui mau i kā mākou hana hana.

4. Ka hana alumini

ʻO ka hana alumini kahi kaʻina hana e hana ʻia ai nā mea alumini a mālama ʻia ma o nā kaʻina hana e hana ai i nā huahana alumini like ʻole. ʻO nā ʻanuʻu nui ka extruding, rolling a me ka hoʻolei ʻana. Hoʻokumu ka Extrusion i ke kaomi ma ka hoʻokuʻu ʻana i nā mea alumini ma o ka make i loko o kahi extruder, e hoʻokuʻu ʻia i loko o kahi mea me ke ʻano o ke keʻa i makemake ʻia. He kūpono kēia ʻano no ka hana ʻana i nā huahana paʻakikī e like menā puka makani, na pani puka a me na paipu. ʻO ka ʻōwili ʻana ʻo ia ka hele ʻana i nā poloka alumini a i ʻole nā ​​​​palapala ma o ke ʻano o nā kaʻina hana ʻōwili ma o ka wili wili e hana ai i loko o ka mānoanoa a me ka laula e pono ai. He kūpono kēia ʻano hana no ka hana ʻana i nā huahana e like me ka alumini alumini, nā ʻāpana alumini alumini a me nā hue alumini. ʻO ka hoʻolei ʻana, ʻo ia ka ninini ʻana i ka alumini hoʻoheheʻe ʻia i loko o kahi poʻi, a laila hoʻomaloʻo ʻia a paʻa i ke ʻano o ka huahana i makemake ʻia. He kūpono kēia ʻano hana no ka hana ʻana i nā mīkini alumini, nā ʻāpana mīkini, a me nā ʻāpana kaʻa, a me nā mea ʻē aʻe. Ma o kēia mau kaʻina hana, hiki ke hana pololei ʻia nā mea alumini i nā ʻano huahana alumini me nā hoʻohana like ʻole.

5. Hana hou

ʻO ka hana hou ʻana o ka alumini he mea ʻoi aku ka maikaʻi o ka ikehu, e hoʻohana ana i ka 5% wale nō o ka ikehu e pono ai e hana i ka alumini kumu mai nā mea maka. Eia kekahi, ʻaʻole e hoʻohaʻahaʻa ke kaʻina hana o ka alumini i kona maikaʻi, e ʻae iā ia e hoʻohana mau ʻia. ʻO ka ʻoiaʻiʻo, he 75% kupaianaha o nā alumini a pau i hana ʻia i hoʻohana mau ʻia i kēia lā. Hōʻike kēia mau ʻikepili i ka hoʻomau a me ka lōʻihi o ka alumini ma ke ʻano he mea hiki ke hana hou ʻia i nā ʻoihana like ʻole.

Hiki iā Ruiqifeng ke hāʻawi i nā huahana alumini like ʻole e hoʻokō i kāu mau pono. Inā makemake ʻoe e kamaʻilio me kā mākou hui a e aʻo hou e pili ana i ke ʻano e hiki ai iā Ruiqifeng ke pōmaikaʻi i kāu ʻoihana, e ʻoluʻolu ekāhea iā mā˚ou.
