1. Nā hiʻohiʻona haʻiʻōlelo:
Ka hana hoʻoheheʻe leo: Hiki ke hoʻoheheʻe ʻia ka pā pahu alumini paʻa paʻa e hana i kahi papa hoʻoheheʻe kani me ka nui o ke kani kani kiʻekiʻe. I ka manawa o ka wehe ʻana he 1% ~ 3%, ʻoi aku ka kiʻekiʻe o ka leo absorption rate. ʻO ka nui o ke kani ʻana o ke kani i ana ʻia e ke ʻano hawewe kū i ka laulā o 1000Hz a 2000Hz, a hiki i ka 40% a hiki i ka 80%.
ʻO ka hopena hoʻoheheʻe kani o ka alumini pahu: ʻo ka papa hoʻoheheʻe kani i hana ʻia me ka panela sanwiti alumini foam, 20mm mānoanoa, hoʻopaʻa leo: 20 ~ 40dB.
2. Kū'ē i ka wā:
Ka pale ʻana i ka corrosion: ʻike ʻia i ka lewa moana no hoʻokahi makahiki, ʻaʻohe mea ʻino; ma lalo o nā kūlana corrosion wikiwiki, ʻaʻohe mea ʻino i ka hoʻāʻo ʻana i ka wai paʻakai paʻakai no 2 mau makahiki; hōʻike ia he maikaʻi loa ke kūpaʻa ʻana o ka alumini foamed.
ʻAʻohe hoʻoheheʻe wai: ʻO ka nui o ka hoʻoheheʻe ʻana o ka wai o ka alumini foamed he 0.0%. ʻAʻohe hoʻoheheʻe ʻana o ka wai, a ʻaʻohe degradation o ka hana acoustic ma muli o ka haʻahaʻa.
ʻO nā waiwai pale wela/ʻaʻole hiki ke hoʻopau ʻia: ʻO ka alumini puaʻa e palupalu i kahi mahana kiʻekiʻe o 600 ° C, a he mea hiki ʻole ke puhi.
ʻO ka hana insulation: ʻO ka conductivity thermal o ka alumini foamed he 0.25 ~ 0.62W / mK, ka mea like me ka marble, a he hana insulation maikaʻi.
ʻO ke kūpaʻa wela: ʻO ka coefficient hoʻonui linear o ka alumini foamed he 1.934 * 10 ℃, e like me ke koneki, a ʻaʻole maʻalahi ke hoʻololi ʻia e ka wela.
3. Nā waiwai mīkini:
Mechanical waiwai: compressive ikaika: 3 i 17 MPa; ikaika flexural: 3 a 15 MPa; ikaika tensile: 2 i ka 7 MPa;
ʻO ka hana Cushioning: Hiki i ka hoʻoulu ʻana o ka ikehu ke hiki i 8J/cm3～30J/cm3, a hiki i ka alumini foamed ke komo i ka ikehu ma o ka deformation, ʻo ia ka hopena maikaʻi loa o ka ikehu absorption material.
4. Hana mīkini:
Hoʻohana nui ʻia ka pahu alumini ma nā ʻano ʻano like ʻole. He mea porous, māmā a me ke kālā keʻokeʻo me nā hiʻohiʻona maikaʻi o ka hana maʻalahi. Hiki ke ʻoki ʻia, ʻokiʻoki, hoʻolālā ʻia, wili ʻia, a me nā mea ʻē aʻe, a hiki ke hana maʻalahi i nā papa a me nā paʻi. Nā pahu a me nā ʻāpana like ʻole.
5. Palena kaiapuni ʻōmaʻomaʻo:
ʻAʻohe mea ʻawaʻawa: ʻO ka pahu alumini kahi mea i haku ʻia me nā metala a me nā pores, ʻaʻohe mea ʻawaʻawa a ʻaʻole e pakele i nā kinoea ʻona i nā wela kiʻekiʻe.
Hiki ke hana hou: ʻO nā mea kemika nui o ka pahu alumini he alumini alumini a me kā lākou oxides, hiki ke hoʻohana hou ʻia 100% me ka ʻole o ka hoʻohaumia ʻana i ke kaiapuni.
Palekana electromagnetic: Electromagnetic shielding (ma lalo o 200MHz) pale electromagnetic 90dB, me ka maikaʻi o ka hana pale electromagnetic.
6. Nā kahua noi huahana
Ma muli o kāna mau waiwai kūikawā, hiki ke hoʻohana nui ʻia nā huahana foam alumini i ka aerospace, aviation, high-speed trains, urban rail trains, shipbuilding, high-speed rail, construction, tunnels a me nā pale kani ma ke ala. haʻalulu, kiʻekiʻe absorption o ka ikehu hopena, kiʻekiʻe electromagnetic shielding hana, maikaʻi wela insulation, kiʻekiʻe wela kū'ē, ke ahi a me ka non-combustibility. Loaʻa iā ia ke aloha kaiapuni kūikawā.
ʻO ka hana hoʻoheheʻe: Hoʻāʻo ʻia e ka Institute of Solid State Physics, Chinese Academy of Sciences, ʻo ke kumu friction kūloko Q-1 o ka alumini foam hiki i 6 × 10-3.
