Hana ʻia ka pahu alumini ma ka hoʻohui ʻana i nā mea hoʻohui i ka alumini maʻemaʻe a i ʻole ke alumini alumini, a ua hana ʻia ma ke kaʻina hana hū, a loaʻa iā ia nā ʻano o ka metala a me nā ʻōpala i ka manawa like. Loaʻa iā ia ka haʻahaʻa haʻahaʻa, kiʻekiʻe ka hopena absorption hiki, kiʻekiʻe wela ke kūpaʻa, ke ahi ikaika, ka pale ʻana i ka corrosion, ke kani ʻana a me ka hoʻohaʻahaʻa leo, haʻahaʻa thermal conductivity, kiʻekiʻe electromagnetic shielding, ikaika kū i ka wā, kānana hiki, hana maʻalahi, hoʻonohonoho maʻalahi, a kiʻekiʻe. hana pololei. , Hiki ke hoʻokō 'ia ka uhi uhi.
Loaʻa i ka pahu alumini nā waiwai kino, kemika a me ka mechanical a me ka recyclability. ʻO kēia mau waiwai maikaʻi loa o ka alumini foam e loaʻa iā ia nā manaʻo noiʻi ākea i ke kahua waiwai o kēia lā, a he mea ʻenehana hoʻohiki maikaʻi ia, ʻoi aku hoʻi i ka ʻoihana halihali, ʻoihana aerospace a me ka ʻoihana kūkulu hale.
No ke aha i wikiwiki ai ka hoʻomohala ʻana o ka pahu alumini? ʻO ia no ka nui o nā pono o ka alumini foamed, e like me ka nui o 0.1-0.4 mau manawa o ka alumini metala; ʻo kona ʻoʻoleʻa piʻo he 1.5 manawa ko ke kila; ʻO ka hana damping he 5-10 mau manawa o ka alumini metala. I ka 50% deformed ka porosity o 84% alumini foam, hiki iā ia ke komo i ka ʻoi aku ma mua o 2.5MJ / m3 o ka ikehu. I ka manawa o ka hawewe kani ma waena o 800-4000HZ, ʻoi aku ka nui o ka insulation coefficient o ka pahu alumini paʻa-cell ma luna o 0.9. I ka manawa o ka nalu electromagnetic ma waena o 2.6-18GHZ, hiki i ka pale pale electromagnetic o ka alumini foam hiki ke hiki i 60-90dB.
Ma keʻano: he maʻalahi keʻokiʻoki, wili, a me ke kāpiliʻana i ka alumini foamed; hiki ke hoʻopili ʻia i ke ʻano i makemake ʻia ma ka hoʻowili ʻana; hiki ke hoʻomaʻamaʻa ʻia i ka ʻili me ka pena organik a i ʻole nā mea pena; hiki ke uhi ʻia ma nā ʻaoʻao ʻelua e hana i kahi papa māmā nui, ʻoi aku ka rigidity. Hiki ke hoʻokomo ʻia nā mea pahu alumini ma nā wahi kiʻekiʻe me ka ʻole o nā mea hoʻokiʻekiʻe mechanical, e like me: nā kaupaku, nā paia a me nā hale, a me nā mea ʻē aʻe, hiki ke hoʻopili pono ʻia a hoʻopaʻa ʻia me nā wili, a hiki ke hoʻopili ʻia i nā paia a i ʻole nā kaupaku me nā mea hoʻopili. Metala metala - alumini foam - ʻO ka "sandwich" i hoʻokumu ʻia e ka metala metala i hoʻoilina i nā waiwai maikaʻi loa o ka pahu alumini a loaʻa ka ikaika flexural kiʻekiʻe, hiki ke hoʻohana ʻia e like me nā mea kūkulu hale hou, nā ʻāpana hana kiʻekiʻe-rigidity o ka rolling stock, etc.
