ʻO ka pahu alumini kahi ʻano mea hana hou, ʻo ia ka mea metala alumini matrix i hoʻopuehu ʻia i loko o nā ʻōpū he nui e like me nā mea metala ultra-māmā like ʻole, porosity maʻamau o 40% a 98%.
ʻŌhā aluminihe kiʻekiʻe ke kūpaʻa wela, ʻoiai inā hiki i ka helu heheʻe o ka huila, ʻaʻole ia e heheʻe. ʻO ka wela hoʻoheheʻe ʻana o ka alumini alumini maʻamau mai 560 a 700 ℃, akā ʻaʻole heheʻe ka pahu alumini inā ua wela a hiki i 1400 ℃. Eia kekahi, ʻaʻole ia e hoʻokuʻu i nā kinoea ʻino i nā wela kiʻekiʻe, no laila hiki iā ia ke hoʻololi i ka resin foamed a me nā huahana asbestos e like me ka wela-insulating a me nā mea wela i nā manawa he nui.
Hiki i ka pahu alumini ke hoʻopau i ka ikehu kinetic o ka ea i ka ikehu wela ma o ka vibration o ka pā pore, no laila hiki ke hoʻohana ʻia e like me nā panela acoustic no ka hoʻohaʻahaʻa ʻana i ka leo o nā alaloa a me nā alahao, nā alaloa subway, nā keʻena subway, nā alahao, nā loko ʻauʻau, nā hale hālāwai. , lumi lako nui, a pela aku. ʻO ka hoʻololi ʻana i ka mānoanoa o ka pae ea i hoʻonohonoho ʻia ma hope o ka panel acoustic hiki ke hoʻomalu i ke alapine nui o ka coefficient acoustic o ka panel foam alumini, i hiki ke hana ʻia ka panel acoustic no nā leo like ʻole. Eia hou, kapahu pahu aluminiʻaʻole e hoʻomoʻa i ka makū, ma kahi ʻano haʻahaʻa, ʻaʻole i emi ka nui o ke kani ʻana o ka leo, ʻo ia ka mea kani maikaʻi loa i loko o kahi wahi haʻahaʻa.
ʻŌhā aluminiloaʻa i ka nui o nā noi i ka ʻoihana kūkulu. No ka laʻana, me ka alumini foam manufacturing elevator hiki ke hoemi nui i kona kaumaha, pela e hoemi ai i ka ikehu, a me ka pahu alumini ka maikaʻi o ka ikehu absorption hana a hōʻoia i ka palekana o ka elevator. Inā hoʻohana ʻia ka pahu alumini ma ke ʻano he mea hoʻonaninani, ʻaʻole ia he māmā a nani wale nō, akā hiki ke pāʻani i ka hopena ahi a me ke kani.

I ke kūkulu ʻana, ʻo kahi koi maʻamau e hoʻohanamea alumini pahue hana i nā pā pākū no nā hale kiʻekiʻe. ʻO kēia ʻano o ka pale pale pale pale i loaʻa i ka ikehu absorption, ke kani ʻana o ke kani a me ka hana wela, hiki ke hoʻoulu i ka hopena o ke kaomi makani ma nā hale kiʻekiʻe, hoʻokaʻawale a hoʻemi i ka walaʻau, a hoʻomaikaʻi i ka hōʻoluʻolu. ʻAʻole pili wale ka conductivity thermal o ka pahu alumini i ka porosity, akā i ka hāʻawi ʻana i nā voids, ke pāʻani nei ka mea hope i ke alakaʻi alakaʻi, e like me ka hoʻonui ʻana o nā lua bubble ma ka perpendicular i ke kuhikuhi o ka kahe wela e hoʻonui i ka hiki. e pale i ke kahe o ka wela, a ma muli o ka hoʻohui ʻana o ke kuhikuhi a me ka puka ʻana mai o kahi "pā pale pale wela kiʻekiʻe", a no laila he mea hoʻohiki maikaʻi loa.
Aluminum foam mea e like me ke ano hou o ka hale-hana hoʻohui waiwai, me ka haʻahaʻa pili ana, māmā kaumaha, nui kiko'ī ili wahi, kiʻekiʻe kiko'ī mechanical waiwai, maikai damping hana, damping, anechoic, thermal insulation, thermal conductivity, haʻalulu absorption, electromagnetic. pale pale, hoʻoheheʻe ʻana i ka ikehu a me ka pale a me nā waiwai mechanical maikaʻi loa a me nā waiwai kino.
