ʻO ka Pepa Aluminum Coil Hale Hana Hana

ʻO ka hoʻohana ʻana i kahi mea e pili ana i ka nui o nā waiwai o ka mea.Ma muli o kāna mau waiwai maikaʻi loa, ʻo ka alumini kahi ākea ākea o nā noi.

ʻO nā alumini alumini a me nā alumini kekahi o nā mea waiwai nui no ka nui o nā noi.Mai ka makahiki 1956, ʻo ka hana alumini o ka honua ka mea kiʻekiʻe loa i ka metala non-ferrous, ma mua o ka hana keleawe.I kēia manawa, ʻo ka hana ʻana a me ke ʻano o ka alumini (ma ke ʻano o nā tona) ʻelua wale nō i ke kila, e lilo ana i lua metala nui loa i hoʻohana ʻia e nā kānaka;Eia kekahi, he nui loa nā kumu waiwai o ka alumini, a e like me ka helu mua ʻana, ʻoi aku ka nui o nā waihona mineral o ka alumini ma mua o 8% o nā mea i hoʻokumu i ka ʻōpala o ka honua.

ʻO ke kaumaha māmā a me ke kūpaʻa corrosion o ka alumini nā hiʻohiʻona koʻikoʻi ʻelua o kāna hana.

He ʻuʻuku loa ka nui o ka alumini, ʻo 2.7 g/cm³ wale nō.ʻOiai he palupalu ia, hiki ke hana ʻia i loko o nā alumini alumini like ʻole, e like me ka alumini paʻa, ke alumini paʻakikī paʻakikī, ka alumini rust-proof, ka alumini hoʻolei, a me nā mea ʻē aʻe. nā kaʻaahi a me nā moku.Eia kekahi, hoʻohana ʻia ka nui o ka alumini a me kāna mau alumini alumini i nā rockets space, space shuttles a me nā satellite artificial.No ka laʻana, ua haku ʻia kahi mokulele supersonic ma kahi o 70% o ka alumini a me kāna mau alumini alumini.Hoʻohana nui ʻia ka alumini i ka hana moku, a ʻo ka nui o ka alumini i hoʻohana ʻia i loko o kahi moku kaʻa nui e piʻi pinepine i nā tausani mau tona.

ʻO ka alumini ka lua wale nō i ke kālā, ke keleawe a me ke gula i ka conductivity, ʻoiai ʻo kāna conductivity he 2/3 wale nō o ke keleawe, akā ʻo ka nui wale nō ka 1/3 o ke keleawe, no laila ka hoʻoili ʻana o ka nui o ka uila, ka maikaʻi o ka uea alumini. he hapalua wale no o ka uwea keleawe.ʻAʻole hiki ke pale i ka corrosion wale nō ke kiʻi ʻoniʻoni alumini ʻili, akā loaʻa kekahi ʻano o ka insulation, no laila ʻo ka alumini i loko o ka ʻenehana hana uila, uea a me ka ʻoihana kelepona a me ka ʻoihana lekiō he nui nā hoʻohana.

ʻO ka alumini ka mea hoʻokele maikaʻi o ka wela, ʻekolu mau manawa ka nui o kona conductivity wela ma mua o ka hao, no laila hiki ke hoʻohana ʻia ka alumini i ka ʻoihana e hana i nā mea hoʻololi wela, nā mea hoʻoheheʻe wela a me nā mea kuke.

ʻO ka alumini ka ductility maikaʻi (ʻo kona ductility ka lua wale nō i ke gula a me ke kālā), ma 100 ℃ ~ 150 ℃ hiki ke hana ʻia me ka lahilahi ma mua o 0.01 mm alumini foil.Hoʻohana nui ʻia kēia mau pahu alumini no ka hoʻopili ʻana i nā cigakeke, candy, a me nā mea ʻē aʻe.

ʻAʻole maʻalahi ka ʻili o ka alumini ma muli o ke kiʻi ʻoniʻoni pale oxide, a hoʻohana pinepine ʻia e hana i nā reactors kemika, nā lāʻau lapaʻau, nā mea hoʻoheheʻe, nā mea hoʻomaʻemaʻe ʻaila, nā ʻaila a me nā paipu kinoea, etc.

He ʻulaʻula keʻokeʻo kālā ka pauda alumini (he ʻeleʻele ka waihoʻoluʻu o nā metala ma ke ʻano he pauda), a hoʻohana pinepine ʻia no ka hana ʻana i nā uhi, i ʻike mau ʻia ʻo ka pauda kālā a me ka pena kala, e pale i nā huahana hao mai ka ʻino, a ʻo ia hoʻi. uʻi.

Hiki i ke ahi alumini i ka oxygen ke hoʻopuka i ka wela a me ke kukui ʻālohilohi, i hoʻohana mau ʻia i ka hana ʻana i nā mea pahū, e like me ka ammonium alumini pahū (mai ka ammonium nitrate, ka pauka lanahu, ka pauka alumini, ka ʻeleʻele ʻeleʻele a me nā mea hoʻoheheʻe ʻē aʻe), hui pū ʻia. (e like me nā pōkā a me nā pūpū i hana ʻia me ka alumini thermite hiki ke hoʻohana ʻia no ka hoʻouka ʻana i nā pahuhopu paʻakikī e hopu i ke ahi a i ʻole nā ​​pahu pahu, nā pū, a me nā mea ʻē aʻe) a me nā hui kukui (e like me ka barium nitrate 68%, alumini pauda 28%, wormwood 4% ).

Hoʻohana pinepine ʻia ka thermite alumini e hoʻoheheʻe i nā metala refractory a me nā kaʻa kuʻi, a me nā mea ʻē aʻe.ʻO ka pauka alumini a me ka graphite, titanium dioxide (a i ʻole nā ​​​​mea hoʻoheheʻe kiʻekiʻe heʻe metala ʻē aʻe) i kekahi lākiō o ka hui pū ʻana, i uhi ʻia ma ka metala, e ka calcination kiʻekiʻe wela a hana ʻia i nā ceramics metala kiʻekiʻe. ʻenehana.

Loaʻa i ka pepa alumini nā mea hoʻohālikelike maikaʻi o ka mālamalama, e hōʻike ana i ke kukui ultraviolet ʻoi aku ka ikaika ma mua o ke kālā, ʻoi aku ka maʻemaʻe o ka alumini, ʻoi aku ka maikaʻi o kona hiki ke noʻonoʻo, no laila e hoʻohana pinepine ʻia e hana i nā mea hoʻonaninani kiʻekiʻe, e like me nā mea hoʻohālike o ka lā.

Loaʻa i ka alumini nā mea kani a me nā acoustics ʻoi aku ka maikaʻi, no laila ua hoʻohana ʻia ka alumini i nā lumi hoʻolaha, nā kaupaku i nā hale nui o kēia manawa, a me nā mea ʻē aʻe. nā mea hana haʻahaʻa haʻahaʻa, e like me ka waiho ʻana i loko o ka pahu hau, ka waiho ʻana i ka hau, nā kaʻa hau Antarctic, nā mea hana hydrogen oxide.
