ʻO nā mea alumini alumini kiʻekiʻe: kahi koho kipi no ka hoʻolauna ʻana i ke alahaka
2024-04-18 09:52:59
Me ka hoʻomohala wikiwiki o ka ʻepekema a me ka ʻenehana a me ka wikiwiki o ke kūlanakauhale, nā alahaka, ma ke ʻano he mea nui o ka lawe ʻana i ke kūlanakauhale, e hoʻomau mau nei i kā lākou hoʻolālā a me nā ʻano hana. Hoʻohana nui ʻia nā alahaka kila ma muli o ko lākou ikaika kiʻekiʻe a me ke kumu kūʻai haʻahaʻa. Eia naʻe, ma ka lōʻihi o ka manawa, ʻike ʻia nā pilikia e like me ka corrosion a me nā kumukūʻai mālama kiʻekiʻe. E kūʻē i kēia kāʻei kua, ua lilo nā mea alumini alumini kiʻekiʻe i mea koho hou i ke kahua o ke kūkulu ʻana i ke alahaka me kā lākou mau pono hana kūikawā.
ʻO nā pono o nā mea alumini alumini
Nā pōmaikaʻi o ka hoʻolālā māmā
ʻO ka mānoanoa o ka alumini alumini ma kahi o 2.7 g/cm³, ʻo ia wale nō ma kahi o 1/3 o ke kila. He aha ke ʻano o kēia waiwai māmā no ka hoʻolālā ʻana a me ke kūkulu ʻana i ke alahaka? ʻO ka mea mua, hiki i nā hale alahaka māmā ke hoʻemi i nā koi no nā kumu, e ʻae i nā alahaka nui e kūkulu ʻia ma nā wahi me nā kūlana geological maikaʻi ʻole. ʻO ka lua, hiki i nā hale māmā ke hōʻemi i nā kumukūʻai o ka lawe ʻana a me ka hoʻokomo ʻana, he mea koʻikoʻi loa ia ma nā wahi mamao a i ʻole nā wahi me ka palena ʻole. Eia hou, hiki i nā hale māmā ke kōkua i ka hoʻomaikaʻi ʻana i ka hana seismic i ka wā ōlaʻi no ka mea ʻoi aku ka māmā o ke kaumaha e hōʻemi i nā ikaika inertial ma lalo o ka hana ōlaʻi.
ʻO ke koʻikoʻi o ka pale ʻana i ka corrosion
Hiki i nā mea alumini alumini ke hana i kahi kiʻiʻoniʻoni oxide i loko o ke kaiapuni kūlohelohe. Hiki i kēia kiʻiʻoniʻoni oxide ke hoʻopaʻa pono i ka komo ʻana o ka wai a me ka oxygen, a laila e pale ai i ka mea mai ka corrosion. He mea koʻikoʻi kēia i ke kūkulu ʻana i ke alahaka, no ka mea, ʻike pinepine ʻia nā alahaka i nā mea a pono e kū i nā mea. Ke hoʻohālikelike ʻia me nā alahaka kila maʻamau, ʻaʻole pono nā alahaka alumini alumini i ka mālama anti-corrosion pinepine, e hōʻemi nui ana i nā kumukūʻai mālama lōʻihi a me ka hana.
ʻO ka hui kūpono o ka plasticity a me ka processability
He mea maʻalahi ka hoʻokuʻu ʻana a me ka hana ʻana i nā mea alumini alumini, a hiki ke hana ʻia nā profiles me nā ʻāpana keʻa paʻakikī, e hāʻawi ana i nā mea hou aku no ka hoʻolālā alahaka. Hiki i nā mea hoʻolālā ke hoʻolālā i nā hale alahaka nani a kūpono e like me ka mea e pono ai e hoʻokō i nā koi ʻelua o nā kūlanakauhale hou no ka ʻāina a me ka hana. Eia kekahi, ke hoʻomaikaʻi mau nei ka wiliwili alumini alumini a me ka ʻenehana pili, e ʻoi aku ka maʻalahi a me ka wikiwiki o ke kūkulu ʻana i nā alahaka alumini.
Nā waiwai mīkini a me ka ʻenehana pili o nā alumini alumini
ʻO ka noʻonoʻo piha ʻana i nā waiwai mechanical ʻOiai he haʻahaʻa haʻahaʻa ka modulus elastic o nā aluminika, ua hoʻohālikelike ʻia ko lākou ikaika kikoʻī (ka lākiō o ka ikaika a me ka density) me ka, a ʻoi aku ka maikaʻi ma mua o ke kila ikaika kiʻekiʻe. ʻO ia ke ʻano o nā hale alumini alumini hiki ke maʻalahi i ka lawe ʻana i ka ukana like. I ka manawa like, pono e noʻonoʻo ʻia nā hiʻohiʻona elastic deformation o nā alumini alumini i ka wā o ka hoʻolālā ʻana, a ʻo ka ʻoʻoleʻa a me ka ikaika o ka hale e hoʻolālā pono ʻia e hōʻoia i ka palekana a me ka paʻa o ka hale.
Hoʻohou a hoʻomohala ʻana i nā ʻenehana Hoʻohui
Hiki ke hoʻohui ʻia nā alumini alumini ma nā ʻano like ʻole, me nā pili bolted, nā pili rivet a me nā pilina welded. I mea e hōʻemi ai i ka corrosion galvanic, hoʻohana mau ʻia nā rivets aluminika a i ʻole nā bolts i nā hale alumini alumini. I ka manawa like, me ka hoʻomohala ʻana i ka ʻenehana welding, ua hoʻomaikaʻi maikaʻi ʻia ka hana wili o nā alumini alumini. ʻO MIG welding (melting inert gas welding) a me TIG welding (tungsten inert gas welding) ʻelua mau ʻano hana wili alumini alumini e hiki ai ke hāʻawi i nā hui welded kiʻekiʻe e kū ana i nā kūlana kiʻekiʻe o ke kūkulu ʻana i ke alahaka.
Hana kūpaʻa o nā alahaka aluminika
Nā Lae Hoʻolālā no ka Hana Paʻa
Hiki ke pilikia nā ʻāpana alumini alumini i ka piko ʻaoʻao a me ka torsional instability i ka wā e kulou ana, pono e nānā kūikawā i ka wā hoʻolālā. I mea e hoʻomaikaʻi ai i ka paʻa o ka hale, hiki i nā mea hoʻolālā ke hana i nā ʻano like ʻole, e like me ka hoʻohui ʻana i nā kākoʻo ākea, hoʻololi i ke ʻano cross-sectional, me ka hoʻohana ʻana i nā stiffeners, etc. a e hōʻoia i ka palekana o ka hale ma lalo o nā ukana like ʻole.
Aluminum alloy alahaka examples
ʻO Hangzhou Qingchun Alanui Waena Waena Alahaka
Ke hoʻohana nei kēia alahaka i ka pahu pahu pahu alumini alloy truss structure, a ʻo ka mea alahaka nui he 6082-T6 alumini alumini. ʻO ke alahaka 36.8 mika ka lōʻihi he 11 tons wale nō ke kaumaha, e hōʻike ana i nā pono o ka hoʻolālā māmā o nā alahaka alumini. ʻO ka hoʻolālā o ke alahaka ʻaʻole i noʻonoʻo wale i ka hana, akā noʻonoʻo pono i ka lokahi me ke kaiapuni a puni, lilo i ʻāina nani i ke kūlanakauhale.

Alahaka Pedestrian Xujiahui Shanghai
ʻO ke alahaka hele wāwae o Shanghai Xujiahui i hoʻolālā ʻia e Tongji University i hana ʻia me 6061-T6 alumini alumini, me ka lōʻihi hoʻokahi o 23 mika, ka laulā o 6 mau mika, kahi kaumaha make o 150kN wale nō, a me ka nui o ka ukana o 50t. ʻO ka hana wikiwiki a me ka hoʻohana ʻana i kēia alahaka e hōʻike ana i ka pono a me ka pono o nā alahaka alumini alumini i nā kūlanakauhale hou.

Alahaka Pedestrian Beishi Xidan
Ua kūkulu ʻia ke alumini alumini superstructure o ka Xidan Pedestrian Bridge ma Bei City e kahi hui kālā ʻē aʻe, a ʻo 6082-T6 ka mea nui alumini alloy profile. ʻO 38.1m ka lōʻihi o ka lōʻihi nui, ʻo 8m ka laulā ākea o ke alahaka, a ʻo ka lōʻihi he 84m. Ua hoʻolālā ʻia ke alahaka me ka ʻoluʻolu a me ka palekana o ka poʻe hele wāwae. I ka manawa like, ʻo ka hoʻohana ʻana i nā mea alumini alumini e hāʻawi i ke alahaka i kahi ola ʻoi aku ka lōʻihi o ka lawelawe a me nā kumukūʻai mālama haʻahaʻa.

Ka hopena
ʻO ka hoʻohana ʻana i nā mea alumini alumini kiʻekiʻe i ke kūkulu ʻana i ke alahaka ʻaʻole wale e hoʻomaikaʻi i ka hana hoʻolālā a me ka lōʻihi o nā alahaka, akā lawe pū kekahi i nā mea hou aku i ka hoʻolālā alahaka. Me ka holomua o ka ʻepekema waiwai a me ka hoʻomohala ʻana i ka ʻenehana hana, manaʻo ʻia nā alahaka aluminika e pāʻani i kahi kuleana nui i ke kūkulu ʻana i ka alahaka e hiki mai ana a lilo i loulou koʻikoʻi e pili ana i nā kūlanakauhale hou.
