1. He aha ka Foamed Metal a me Foamed Aluminum
I ka wā o ka mōʻaukala, ʻo ka loaʻa ʻana o nā metala foamed he mea koʻikoʻi koʻikoʻi i ka hoʻololi ʻana o ke kahua holoʻokoʻa o ka ʻenehana waiwai. ʻO ka pahu metala kahi mea i loaʻa i kahi hale metala me ka nui o nā pores i hoʻopiha ʻia me nā kinoea ma ka hale. Hiki ke loaʻa nā pores o kēia mau ʻōhua metala ma ke ʻano o nā interconnections a i ʻole nā ​​sila hermetic, i ʻike ʻia he open-cell a me closed-cell foams. Iwaena o lakou,pahu aluminii kēia manawa ka metala foam me ka mana nui loa no ka noi ʻana, a ua ʻike ʻia ʻo ia ka "hōkū metala" ma muli o ke ʻano o nā waiwai maikaʻi loa, e like me ke porosity kiʻekiʻe, ka haʻahaʻa haʻahaʻa, ke kaumaha māmā, ka ikaika kiʻekiʻe, ka hoʻopiʻi maikaʻi, ka hopena maikaʻi. maikaʻi ke kani kani, a me ka pale electromagnetic. "metal star", hoʻohana nui ʻia i ka ʻenekinia aerospace, ka hana ʻana a me nā ʻano hana ʻē aʻe ma ke kahua o ka ʻepekema kino.

ʻO nā hiʻohiʻona hoʻolālā o ka pahu alumini: (a) ʻO ka pahu alumini puka wehe; (b) ʻO ka pahu alumini paʻa paʻa

2. Na waiwai a me na noi oAluminum Foam
ʻO ka pahu alumini he mea metala me ka porosity kiʻekiʻe a me ka hana porous, kahi i hoʻopaʻa ʻia ai nā pores i hoʻopaʻa ʻia ma kahi o ʻekolu hapaha o ka nui o ka nui o ka mea metala, e hoʻomālamalama loa i ka mea. Ma kahi o kēia mau waiwai, loaʻa i ka foam alumini nā waiwai hoʻoheheʻe ikaika a me ka compressibility kiʻekiʻe. E pili ana i ka density, ua ʻike ka poʻe noiʻi ʻo ka hapa nui o nā kumulāʻau alumini e loaʻa i ka density ma kahi o 0.4-1.2 g-cm-3. Eia kekahi, ʻo ka pahu alumini he kani-absorbing, recyclable a he haʻahaʻa haʻahaʻa thermal conductivity.

Hoʻomaikaʻi ʻia ka hana ʻāpana bilge kūʻē i ka hopena: 1 - ʻili luna; 2 –aluminikapahu pahu; 3 - ʻili haʻahaʻa

E pili ana i nā noi, ʻo ka pale electromagnetic, māmā a me nā waiwai absorptive o ka alumini foam e lilo ia i moho kūpono no nā ʻāpana i hoʻohana ʻia i nā ʻenehana fusion controlled, automotive, aerospace a me nā ʻoihana kūkulu ma muli o kona hiki ke pale aku i nā kaiapuni kino. I nā polokalamu fusion i hoʻopaʻa ʻia, ʻo ka pahu pahu alumini paʻa kahi mea pale electromagnetic maikaʻi loa. Ma muli o ka hoʻopili ʻana o ka skeleton foam aluminika, nona kahi ʻāpana kikoʻī kikoʻī nui a me ka hiki ke hoʻopili a hōʻike i nā hawewe electromagnetic, nā ʻano poho like ʻole, e like me nā poho absorption a me nā poho noʻonoʻo, e loaʻa i ka pahu alumini, e hāʻawi i ka ʻO ka alumini puʻupuʻu maikaʻi loa i nā waiwai pale electromagnetic. A ua ʻike ʻia nō hoʻi ke emi nei ka pono pale electromagnetic o ka pahu alumini a laila hoʻonui ʻia me ka piʻi ʻana o ka hawewe electromagnetic. I ka ʻoihana aerospace, hoʻohana ʻia ka pahu alumini ma ke ʻano he ʻāpana i ka hana ʻana i nā cones space a i ʻole turbines, kahi mea e pono ai no ka hōʻemi ʻana i ke kaumaha o nā ʻāpana mokulele ma muli o ka haʻahaʻa haʻahaʻa o ka pahu alumini. Eia kekahi, ma ke ʻano he mea hoʻonaninani maikaʻi loa, hoʻohana ʻia ka pahu alumini i ka hana ʻana i nā mea hoʻoheheʻe mokulele, nā mea hoʻoheheʻe haʻalulu a me ka lalo o nā capsules hoʻihoʻi ʻana i nā mokulele, kahi e hiki ai i ka pae palekana a pale i nā astronauts a me nā lako lewa. Ma ka lawe pono ʻana i ka ikehu a me ka hoʻoheheʻe ʻana i nā haʻalulu, hiki i ka pahu alumini ke hōʻoia i ka palekana o nā astronauts i ka hopena o kahi hopena pae moku.
I ka ʻoihana kaʻa, kōkua ka pahu alumini e hōʻemi i ka nui o nā ʻāpana i hoʻohana ʻia i loko o ke kiʻi, e hoʻomaikaʻi i ke kaʻina hana, ʻo ia ka mea e kōkua i ka hōʻemi ʻana i nā kumukūʻai a hoʻomaikaʻi i ka hana. I kēia manawa, hoʻohana ʻia ka ʻūhā alumini i nā pahu pahu, nā lālā keʻa a me nā kaola puka i nā hale kino kaʻa ma ka mākeke.

I ka hana kūkulu hale, ka hoʻohana nui opahu aluminihe mea pale, pale ahi i ka walaau nui. ʻO nā hiʻohiʻona maʻamau o nā noi hoʻolālā o ka pahu alumini paʻa paʻa ʻo London Underground station a me ka SOHO Revival Square ma Shanghai, kahi i hoʻohana ai nā mea hoʻolālā i ka nui o ka pahu alumini no ke kani ʻana a me ka insulation.

3. Ka hopena
ʻO ka loaʻa ʻana o ka pahu alumini i manaʻo ʻia he hana kupaianaha.ʻŌhā aluminihui pū ʻia nā waiwai pale electromagnetic maikaʻi loa, ke kaumaha māmā, haʻahaʻa haʻahaʻa, vibration damping a me nā waiwai absorption ikehu, e hoʻohana nui ʻia i nā ʻoihana like ʻole i kēia lā. ʻO ka mea e mahalo ai, ʻo ka alumini foam kekahi huahana pili i ke kaiapuni i hiki ke hana hou ʻia, ʻo ia hoʻi he mea hoʻomau i manaʻo ʻia e hoʻohana ʻia i ka nui o nā noi ʻoihana i ka wā e hiki mai ana.
