ʻO nā metala non-ferrous i wehewehe haiki, i ʻike ʻia hoʻi me nā metala non-ferrous, he huaʻōlelo hui no nā metala a pau koe ka hao, manganese, a me ka chromium; ʻO ka ʻōlelo ākea, loaʻa pū nā metala non-ferrous i nā ʻāpana non-ferrous (nā ʻāpana i hana ʻia ma ka hoʻohui ʻana i hoʻokahi a i ʻole kekahi mau mea ʻē aʻe i kahi matrix metala non-ferrous (ʻoi aku ka nui ma mua o 50%).

No ke aha ke alumini he metala lele?
He haʻahaʻa haʻahaʻa haʻahaʻa ka alumini he 2.7g/cm ³ wale nō, a aia kahi kiʻiʻoniʻoni Al₂O₃ ma luna o ka ʻili, e pale ana i ka alumini kūloko mai ka hana ʻana a ʻaʻole maʻalahi i ka oxidized. He mea maʻamau ia no nā mokulele, a ʻo 70% o nā mokulele hou i hana ʻia me ka alumini aalumini alumini, no laila ua kapa ʻia ʻo ia me ka lele lele.

No ke aha he trivalent ka alumini?
ʻO ka waiho wale ʻana, ʻo ka hoʻonohonoho ʻana o nā electrons ma waho o nā ʻātoma alumini he 2, 8, 3.
ʻAʻole lawa ka helu electron o waho, ʻaʻole paʻa ke ʻano, a nalowale maʻalahi nā electron ʻekolu, no laila ke ʻike pinepine ʻia lākou he trivalent maikaʻi. Eia naʻe, ʻike maopopo ʻia ʻekolu mau electron i ʻoi aku ka paʻa ma mua o ka electron o waho o ka sodium a me nā electrons waho ʻelua o ka magnesium, no laila ʻaʻole like ka alumini e like me ka sodium a me ka magnesium.

No ke aha e koi pinepine ai nā profiles alumini i ka mālama ʻana i ka ʻili?
Inā ʻaʻole mālama ʻia nā profiles alumini me ka mālama ʻana i ka ʻili, ʻaʻole ʻoluʻolu ko lākou hiʻohiʻona a ua maʻalahi lākou i ka corrosion i ka ea haʻahaʻa, e paʻakikī ana e hoʻokō i nā koi kiʻekiʻe a me ke kūʻē i ka wā o nā profile alumini i nā mea kūkulu hale. I mea e hoʻomaikaʻi ai i nā hopena hoʻonaninani, hoʻomaikaʻi i ka pale ʻana i ka corrosion, a hoʻonui i ke ola lawelawe, pono maʻamau nā profile alumini e mālama i ka mālama ʻana.

No ke aha i ʻoi aku ka maikaʻi o ka alumini ma mua o ka hao?
ʻOiai ʻoi aku ka nui o nā mālama ʻana o ka alumini ma ka ʻōpala o ka Honua ma mua o ka hao, ʻoi aku ka paʻakikī o ke kaʻina hana o ka alumini ma mua o ka hao. ʻO ka alumini ka mea metala ikaika, a pono ka hoʻoheheʻe ʻana i ka electrolysis. ʻO ke kumukūʻai o ke kaʻina hana holoʻokoʻa ʻoi aku ka kiʻekiʻe ma mua o ka hao, no laila ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ka alumini ma mua o ka hao.

No ke aha e hoʻohana ai nā kini soda i nā kini alumini?

Loaʻa i nā kini alumini nā mea maikaʻi: ʻaʻole hiki ke haki; Māmā; ʻAʻole translucent.

Ua hana ʻia ʻo Wang Laoji, Babao Congee, a me nā mea ʻē aʻe i nā kini hao paʻakikī, no ka mea, ʻaʻohe kaomi o nā mea paʻi, a ua maʻalahi nā kini alumini. ʻOi aku ka kiʻekiʻe o ke kaomi i loko o ka soda ma mua o ka maʻamau, no laila ʻaʻohe pono e hopohopo e pili ana i ka deformation ma lalo o ke kaomi. A hiki i nā kini alumini ke hōʻoia i ke kaomi o carbon dioxide i loko o ka soda, e ʻae i ka soda e loaʻa i kahi hopena ʻono maikaʻi.

He aha nā hoʻohana o ka alumini?
He mau miliona ka hoʻohana ʻana o ka alumini, akā i ka hōʻuluʻulu ʻana, loaʻa iā ia nā hoʻohana nui aʻe:
Hoʻohana ʻia nā mea alumini i ka mokulele a me ka aerospace e hana i nā ʻili mokulele, nā papa fuselage, nā kaola, nā rotors, propellers, nā pahu wahie, nā pā pā, a me nā kia pae ʻana, a me ka moku, rocket forging apo, spacecraft wall panels, etc. i ka hoʻopili ʻana i nā mea inu, nā meaʻai, nā mea hoʻonaninani, nā lāʻau lapaʻau, nā paka, nā huahana ʻoihana, a me nā mea ʻē aʻe. nā ʻano mea alumini alumini no nā kaʻa. ʻO nā kiʻi porous nui no nā subways a me nā kaʻa māmā e hoʻopiha i ka ʻāpana home a hoʻokō i nā koi o ka localization subway. Hoʻohana ʻia lākou no ka hana ʻana i nā kaʻa kaʻa, nā kaʻa subway, nā kaʻa kaʻa kaʻaahi, nā ʻāpana kino o ke kaʻa kaʻa kaʻa kiʻekiʻe, nā puka a me nā puka makani a me nā pahu ukana, nā ʻāpana mīkini kaʻa, nā ea, radiators, panels kino, huila huila, a me nā mea moku. ʻO ka mea alumini i hoʻohana ʻia no ka hoʻopili ʻana he hōʻailona ia o ka pae hana alumini o ka ʻāina, i hana ʻia mai nā kini alumini āpau.

Hoʻohana nui ʻia ka alumini ma ke ʻano o nā ʻāpana lahilahi a me nā foil e like me nā mea hoʻopili metala, hana i nā kini, nā pāpale, nā ʻōmole, nā barela, a me nā pahu pahu. Ua haʻi aku ka ʻoihana paʻi alumini i ka "alakaʻi a me ke ahi" a ua komo i ke au o ka "mālamalama a me ka uila" ... Ua hāʻawi nā pāpaʻi PS i hoʻokumu ʻia i ka alumini i ke kākoʻo ikaika no kēia hoʻololi ʻana i ka ʻoihana paʻi. Hoʻohana nui ʻia nā mea alumini no nā mea uila ma nā ʻano like ʻole e like me busbars, wiring, conductors, nā mea uila, refrigerators, cables, etc. nā huahana like i lawe ʻia mai; Hoʻopiha ka capacitor foil electrolytic hana kiʻekiʻe i ke āpau o ka home. Hoʻohana nui ʻia nā mea alumini a me nā alumini alumini no ka hoʻonaninani ʻana i nā hale kūkulu hale, nā puka a me nā puka makani, nā kaupaku, nā mea hoʻonaninani, a me nā mea ʻē aʻe ma muli o ko lākou kūpaʻa corrosion maikaʻi loa, lawa ka ikaika, ka hana maikaʻi loa, a me ka hana kuʻi.
