ʻO nā ʻano o ke ʻano alumini ʻoihana Chongqing a me ka mālama ʻili - i hana kūikawā ʻia no ka ʻoihana alumini.

ʻO nā ʻano alumini ʻoihana Chongqing e hōʻike ʻia e ka maʻemaʻe kiʻekiʻe a me ke kūpaʻa maikaʻi i ka pala. E like me kā mākou e ʻike nei, pane ka alumini maʻemaʻe me ka oxygen i ka lewa, a e hana ʻia kahi ʻili oxide kūlohelohe lahilahi a mānoanoa ma luna o ka ʻili o ka alumini, ʻoi aku ka wikiwiki a me ka mānoanoa ma mua o nā ʻili oxide metala ʻē aʻe, no laila e pale ai i ka pala o nā kinoea ʻino a me ka makū i ka lewa a ke pāʻani nei i kahi kuleana pale.
ʻO ke ʻano alumini ʻoihana ʻo Chongqing he alumini i hana kūikawā ʻia, me nā ʻano ʻokoʻa a me ka mālama ʻana i ka ʻili o ka huahana. No laila he aha ka hana o ka mālama ʻana i ka ʻili? No ka mea, maikaʻi ke kūpaʻa ʻana o ka alumini maʻemaʻe i ka pala, akā ʻaʻole maikaʻi kona ikaika mechanical, kahi e kaupalena ai i ka hoʻohana ʻana o ka alumini i kekahi ʻano. No laila, hoʻohui ka poʻe i kekahi mau metala ʻē aʻe e like me ka magnesium, ke keleawe a me ka zinc i loko o ka alumini e hana i nā ʻano mea hoʻohui alumini like ʻole. Kiʻekiʻe ka ikaika mechanical o nā mea hoʻohui alumini, kahi e hoʻomaikaʻi nui ai i ka ikaika mechanical o ka alumini a hoʻonui i kona laulā noi. ʻOiai he kiʻekiʻe ka ikaika mechanical o nā mea hoʻohui alumini, ʻoi aku ka ʻino o ko lākou kūpaʻa corrosion ma mua o ka alumini maʻemaʻe, no laila hiki ke pala ma muli o ka oxidation. Pono kēia i ka uhi pauka e pale i nā ʻano mea hoʻohui alumini. Ua hoʻohana nui ʻia ka mea hoʻohui alumini i nā puka, nā puka makani, nā paia pale a me nā huahana ʻē aʻe o nā hale no nā makahiki he nui ma muli o kona kaumaha kikoʻī liʻiliʻi, ka maʻalahi o ka hana ʻana a me ka ikaika mechanical kiʻekiʻe.
