He mea nui nā alahaka i ka mōʻaukala kanaka. Mai ka wā kahiko i hoʻohana ai ka poʻe i nā lāʻau i ʻoki ʻia a hoʻopaʻa ʻia i nā pōhaku e hele ai i nā ala wai a me nā awāwa, a i ka hoʻohana ʻana i nā alahaka a me nā alahaka i hoʻopaʻa ʻia i ke kaula, he mea kupaianaha ka loli. ʻO ka wehe hou ʻana o ke alahaka ʻo Hong Kong-Zhuhai-Macao he mea koʻikoʻi i ka mōʻaukala o nā alahaka. I ke kūkulu ʻana i ke alahaka o kēia wā, ma waho aʻe o ka hoʻohana ʻana i nā hale paʻa i hoʻoikaika ʻia, nā mea metala, ʻoi aku ka nui o nā alumini alumini, ua lilo i mea koho nui ma muli o ko lākou mau pono like ʻole.
I ka makahiki 1933, ua hoʻohana ʻia ke alahaka alumini alumini mua o ka honua ma kahi alahaka e kahe ana i kahi muliwai ma Pittsburgh i ʻAmelika Hui Pū ʻIa. ʻOi aku ma mua o ʻumi makahiki ma hope mai, i ka makahiki 1949, ua hoʻopau ʻo Kanada i kahi alahaka alumini a pau e pili ana i ka muliwai Saguenay ma Quebec, me ka lōʻihi hoʻokahi a hiki i 88.4 mika. ʻO kēia alahaka ka hale alumini mua loa o ka honua. He uwa ko ke alahaka ma kahi o 15 mika ke kiʻekiʻe a me ʻelua alahele no ke kaʻa kaʻa. Ua hoʻohana ia i ka alumini alumini 2014-T6 a he 163 tons ka nui. Ke hoʻohālikelike ʻia i ke alahaka kila i hoʻolālā mua ʻia, ua hoʻemi ʻia ke kaumaha ma kahi o 56%.
Mai ia manawa, ʻaʻole hiki ke pale ʻia ke ʻano o nā alahaka alumini alumini. Ma waena o 1949 a me 1985, ua kūkulu ʻo United Kingdom ma kahi o 35 mau alahaka alumini alumini, ʻoiai ua kūkulu ʻo Kelemania ma kahi o 20 mau alahaka ma waena o 1950 a me 1970. ʻO ke kūkulu ʻana i nā alahaka he nui i hāʻawi i ka ʻike waiwai no nā mea hana alahaka alumini e hiki mai ana.
Ke hoʻohālikelike ʻia me ke kila, ʻoi aku ka haʻahaʻa o nā mea alumini alumini, e ʻoi aku ka māmā, me ka 34% wale nō o ke kaumaha o ke kila no ka nui like. Eia nō naʻe, loaʻa iā lākou nā ʻano ikaika e like me ke kila. Hoʻohui ʻia, hōʻike nā alumini alumini i ka elasticity maikaʻi loa a me ka pale ʻana i ka corrosion me ka haʻahaʻa haʻahaʻa o ke kumukūʻai mālama hale. ʻO ka hopena, ua loaʻa iā lākou ka noi nui i ke kūkulu ʻana i ke alahaka o kēia wā.
Ua hana nui ʻo Kina i ka hana ʻana i ke alahaka. ʻO ke alahaka ʻo Zhaozhou, e kū ana ma mua o 1500 mau makahiki, ʻo ia kekahi o nā mea kiʻekiʻe loa o ka ʻenehana alahaka Kina kahiko. I kēia au hou, me ke kōkua o ka Soviet Union mua, ua kūkulu pū ʻo Kina i kekahi mau alahaka kila, me nā alahaka ʻo Yangtze River ma Nanjing a me Wuhan, a me ke alahaka ʻo Pearl River ma Guangzhou. Eia naʻe, ʻike ʻia ka palena o ka hoʻohana ʻana i nā alahaka alumini alumini ma Kina. ʻO ke alahaka alumini alumini mua ma Kina,ʻo ia ke alahaka hele wāwae ma ke alanui Qingchun ma Hangzhou, i kūkuluʻia ma 2007. Ua hoʻolālāʻia a hoʻokomoʻia kēia alahaka e nā mea hoʻokele alahaka German, a ua laweʻia mai nā mea a pau mai Germany. I kēlā makahiki hoʻokahi, ua hoʻomohala piha ʻia ka alahaka hele wāwae ma Xujiahui, Shanghai, a hana ʻia ma ka home me ka hoʻohana ʻana i nā hale alumini alumini. Ua hoʻohana mua ʻo ia i ka alumini alumini 6061-T6 a, ʻoiai ʻo kona paona ponoʻī 15-ton, hiki ke kākoʻo i kahi ukana o 50 tons.
I ka wā e hiki mai ana, loaʻa i nā alahaka aluminika nā manaʻo hoʻomohala nui ma Kina no nā kumu he nui:
1 Ke ulu nui nei ka hana ʻana o ke kaʻaahi holo māmā o Kina, ʻoi loa ma nā ʻāina paʻakikī o nā ʻāpana komohana me nā awāwa a me nā muliwai he nui. ʻO nā alahaka alumini alumini, ma muli o ko lākou maʻalahi o ka lawe ʻana a me nā waiwai māmā, manaʻo ʻia he mākeke koʻikoʻi.
2 He ʻeleʻele nā mea kila a maikaʻi ʻole ka hana ma nā wela haʻahaʻa. Hoʻopilikia nui ka ʻino ʻana o ke kila i ke kūpaʻa o ke alahaka, ka hopena o nā kumukūʻai mālama ʻoi aʻe a me nā pōʻino palekana. I ka hoʻokaʻawale ʻana, ʻo nā mea alumini alumini ka ikaika o ka corrosion a hana maikaʻi i nā haʻahaʻa haʻahaʻa, e kūpono ana iā lākou no nā kūlana aniau like ʻole a me ka hōʻoia ʻana i ka lōʻihi o ka lōʻihi. ʻOiai ʻoi aku ka kiʻekiʻe o nā alahaka alumini alumini i nā kumukūʻai kūkulu mua, hiki i kā lākou uku mālama haʻahaʻa ke kōkua i ka hōʻemi ʻana i ke kumu kūʻai i ka manawa.
3 Ua hoʻomohala maikaʻi ʻia ka noiʻi ʻana i nā panela alahaka aluminika, ma ka home a me ka honua, a hoʻohana nui ʻia kēia mau mea. Hāʻawi nā holomua i ka noiʻi waiwai i ka hōʻoia ʻenehana no ka hoʻomohala ʻana i nā alaleʻa hou e kūpono i nā koi hana like ʻole. ʻO nā mea hana alumini Kina, ʻo ia hoʻi nā ʻoihana nunui e like me Liaoning Zhongwang, ua neʻe mālie i kā lākou manaʻo i nā profile alumini ʻoihana, e kau ana i ke kumu no ke kūkulu ʻana i ke alahaka alumini.
4 ʻO ka hana wikiwiki ʻana o ke kaʻaahi kūlanakauhale ma nā kūlanakauhale nui o Kina ke kau nei i nā koi koʻikoʻi no nā hale mai luna mai. Ma muli o ko lākou mau pono kaumaha koʻikoʻi, ʻike ʻia e hoʻolālā ʻia a hoʻohana ʻia nā alahaka alahaka alumini alumini a me nā alahaka i ka wā e hiki mai ana.
