Hoʻopaʻa ʻia ke kani ʻana o ke kani a hoʻopaʻa leo i ka pahu Aluminum Foam
1. ʻAno kemika.
ʻO ka pahu pahu alumini: 97% ka pauka alumini, 3% mea hoʻoulu, 1% TiH2
ʻO ka hoʻonui ʻana i ka viscose, 2% Ca. ʻO lākou ka mea mālama kaiapuni ʻaʻohe pollution.
| Pepa ʻikepili hana (Pure Aluminum) | |||
| ʻO ka mānoanoa(g/cm³) | Ka ikaika hoʻopili(Mpa) | Kulou ikaika(Mpa) | Ka hoʻoemi ʻana i ka ikehu(KJ/M³) |
| 0.25~0.30 | 3.0~4.0 | 3.0~5.0 | 1000~2000 |
| 0.30-0.40 | 4.0~7.0 | 5.0~9.0 | 2000~3000 |

2.Electrical hiʻona o nā mea.
ʻOi aku ka liʻiliʻi o ka conductivity o ka mea alumini foam ma mua o ka mea alumini paʻa.
ʻOi aku ka liʻiliʻi o ka conductivity thermal o ka pahu alumini ma mua o ka alumini paʻa, ma kahi o 0.1 - 0.2 mau manawa o ka alumini paʻa.
Eia kekahi, ʻo ka alumini foam he paʻa paʻa, ʻaʻole hiki ke puhi ʻia, ʻaʻole maʻalahi i ka oxidation, ʻaʻole maʻalahi e hana i ka wā kahiko, maikaʻi ke kū ʻana i ka wā,maikaʻi ka ho'ōla a me ka ho'ōla houʻana.
ʻO ka hana pale electromagnetic maikaʻi loa: inā he 2.6-18GHZ ka hawewe electromagnetic,
hiki ke hiki i ka 60-90dB ka mana pale electromagnetic o ka pahu alumini.
3.Corrosive mau mea waiwai.
Ka pale ʻana i ka ʻino: i ka ʻike ʻia ʻana o ke kaiapuni lewa moana no hoʻokahi makahiki, ʻaʻohe mea ʻino ʻole:
ʻO ke kūlana corrosion wikiwiki, ka hoʻokolohua paʻakai paʻakai wai 2 mau makahiki me ka ʻole.
No ka hana ʻana i ka hoʻomaʻamaʻa anti-corrosion surface, hoʻomaikaʻi hou i ka pale ʻana i ka corrosion.
4.Acoustic hiʻona.
20-40dB
5.Vibration hiʻona.
Ka ikaika absorption o ka hopena ikehu, ikehu ikehu hiki basically hiki i oi aku mamua o 50%, ka anuu wahi ikehu pono o 80% a 90%, hiki ke lilo i maikai absorption o waho ikehu, hoemi i ka hopena o ka poino.
ʻO ka hoʻoheheʻe ʻana o ka alumini foam e pili ana i kona hoʻopili maikaʻi ʻana i ka haʻalulu a i ʻole ka mana o ka ikehu impulse. He mea koʻikoʻi ka haʻi haʻalulu a i ʻole ke kū ʻana i ka hopena i ka lawe ʻana i nā kaʻa. ʻOi aku ka maikaʻi o ka alumini foam ma mua o nā mea waiwai ʻē aʻe e hoʻomoʻi i ka mana o ka ikehu hopena, he isotropic i ka hana, ʻo ia ka mea paʻa kūpono.
ʻO ka hana hoʻoheheʻe kiʻekiʻe a me ka hopena o ka ikaika absorption rate: hiki ke hoʻoheheʻe i ka alumini metala 5-10 mau manawa.
ʻO ka pahu alumini me ka porosity o 50% hiki iā ia ke komo i ka ʻoi aku ma mua o 2.5MJ/M3C o ka ikehu ke loaʻa iā ia kahi ʻano o 84%.
E ʻoki i nā ʻaoʻao like ʻole me ke kū pololei.
E ʻoki i loko o ka mānoanoa i koi ʻia e nā mea kūʻai aku e hana i ka pahu alumini
Hoʻopili ʻia ʻo Aluminum Foam
