Ua ʻike ʻia ʻo Aluminum foam (ke metala porous e pili ana i ka aluminika a me kāna mau ʻāpana) no ka hapalua haneli, akā he liʻiliʻi ka hāʻawi ʻana a me ka hoʻohana ʻana. ʻO ke kumu nui o kēia ka haʻahaʻa haʻahaʻa o ka hoʻolālā a me nā waiwai waiwai i ka hana ʻana i nā pahu alumini. ʻO ka hoʻomohala ʻana i ka ʻenehana foam alumini i hiki ke lanakila i kekahi o kēia mau pilikia. Ua hoʻomohala ʻia a noiʻi ʻia nā kaʻina hana like ʻole no ka hana ʻana i nā ʻōpala metala.

Ma mua, ua hoʻoulu ʻia ka poʻe i hana i ia mau mea e nā mea porous maoli e like me ka lāʻau, iwi, koʻa, pumice a me kekahi mau mineral porous ʻē aʻe. ʻO ka hiʻohiʻona maʻamau o kēia mau mea ʻo ia ka hui pū ʻana o ka ikaika kiʻekiʻe, haʻahaʻa haʻahaʻa kikoʻī a me ka lawe ʻana i ka ikehu maikaʻi. I kēia mau lā, hiki i nā mea hana o nā pahu alumini ke hana i nā metala me nā waiwai like me ka maʻalahi. ʻOi aku ka laulā o ka hoʻohana ʻana o nā foam alumini i kēia manawa a he mau kaukani o nā noi like ʻole.

He mea maʻalahi me ka hoʻolālā palena ʻole a me nā noi hoʻolālā. A me kona ʻano hiʻohiʻona ʻokoʻa, loaʻa iā ia nā waiwai hoʻoheheʻe leo i kūpono no nā noi e koi ana i ka hoʻoheheʻe kani a me ka nani. Hoʻohana ʻia ia no nā Facades, nā pale pā, nā pā kaupaku a i ʻole nā ​​​​pakupaku i hāʻule, nā hale ʻaina, nā kaola, nā keʻena, nā hale hale, nā hōʻikeʻike lumi, nā papahele Terrazzo, nā hōʻailona, ​​​​nā kukui kukui, nā hōʻikeʻike, a me nā noi āu e aʻa ai e noʻonoʻo.

Hoʻokumu ka pahu alumini i nā paneli ikaika akā māmā. E like me ke ʻano o ka ʻōniʻoniʻo metala, ʻike maka ʻia, me kahi hiʻohiʻona keaka hou. No ka hoʻolālā ʻana, hana ʻia ka pahu alumini i loko o nā panela ma nā ʻano like ʻole, a ma nā mānoanoa mai 12.7mm a i 43.2 mm (nā mea maʻamau i loaʻa ke kali nei). ʻO nā mana maʻamau ka liʻiliʻi, waena a me ka nui.

Ua waiho ʻia ka ʻili o kēlā me kēia panel i kona ʻano kūlohelohe paʻa e like me ka mea i hana ʻia, a i ʻole e hoʻomākaukau ʻia i ka ʻili e hāʻawi i nā hiʻohiʻona like ʻole. ʻO nā hiʻohiʻona e like me ka ʻili paʻa "shimmering" e nānā i kahi hiʻohiʻona "huhū wai" translucent, ʻoiai nā hoʻolālā maʻamau. ʻO nā ʻaoʻao 2 o kēlā me kēia panel, i ʻike ʻia ʻo 'luna a / a i ʻole lalo, ʻokoʻa loa kekahi i kekahi.

Iecaianoaaiiuo o alumini huʻa

Aia nā kaʻina hana like ʻole no ka hana ʻana i nā pahu alumini.

I kekahi hihia, loaʻa ka pahu metala mai ka metala i hoʻoheheʻe ʻia ma nā ʻano like ʻole. Ke ma'alili a pa'akiki ka alumini, ho'opa'a ka pahu metala. Hoʻohana ʻia nā kahawai kinoea a i ʻole nā ​​​​mea puhi e hana i ka huʻa. Hoʻopau ka mea puhi puhi ma lalo o kekahi mau kūlana a hopena i ka hoʻokuʻu kinoea. Hoʻohana ʻia nā mea hoʻohui kūikawā i kekahi manawa no ka hoʻopaʻa ʻana i nā ʻōmole kinoea i ʻole e hemo ka huʻa ma mua o ka hoʻōla ʻana. Hiki ke hoʻohana ʻia kēia kaʻina hana no ka loaʻa ʻana o nā ʻāpana alumini foam, nā huahana me nā ʻano maʻalahi a me nā sanwied foam alumini. ʻO ia mau huahana he pahu metala e like me ke kumu, i uhi ʻia ma nā ʻaoʻao ʻelua me kahi papa o ka alumini paʻa.

ʻO kekahi ala ʻē aʻe ka hoʻolei ʻana me kahi mea hoʻopihapiha. No ka laʻana, hiki i nā paʻakai paʻakai ke hana ma ke ʻano he mea hoʻopiha, a laila holoi ʻia mai ka matrix aluminika, a ʻike ʻia nā pores ma kahi o nā ʻāpana paʻakai. Hoʻohana pū ʻia ka polyurethane foam me kahi uhi pale wela ma ke ʻano he mea hoʻopiha, e wela ana i ka wā o ka mālama wela.

Hoʻohana ʻia kahi kaʻina hana ʻē aʻe o ka pahu alumini hollow ceramic a i ʻole pōpō metala, i hoʻokomo ʻia i loko o ka matrix metala.

I ka hoʻoheheʻe ʻana, hiki ke hoʻohana ʻia nā granule polymer e hana i nā pores. Ma muli o ke kaʻina hana pōkole loa, ʻaʻole decompose kēia mau granules ma lalo o ka mana o nā wela kiʻekiʻe. Noho lākou i loko o ka matrix metala ma ke ʻano he mea hoʻopiha a wehe ʻia paha e ka mālama wela lōʻihi. I ka hihia hope, loaʻa kahi pahu alumini open-pored.

Hoʻokahi ka ʻaoʻao o ka hana ʻana i nā ʻūhā metala, ʻo ka pauka metallurgy. ʻO ka mea mua, hana ʻia kahi hui o ka pauka alumini me nā mea hoʻohui kūikawā. Ke hoʻomehana ʻia kēlā ʻano hui ʻana, hana ʻia ka ʻōpala a me nā kaʻina sintering, a ma hope o ka hoʻomaloʻo ʻana, e loaʻa i nā ʻano ʻano o ka pahu alumini.

ʻO ke ala hou loa e loaʻa ai nā metala porous ʻo ia ka ʻenehana additive. Me ka hana hoʻohui, hiki ke hoʻomalu pono ʻia ke ʻano a me ke ʻano 3D o ka ʻāpana. Eia nō naʻe, ʻoi aku ka nui o ke kumukūʻai o kēia kaʻina hana a hiki ke hoʻohana ʻia i kahi helu palena o nā metala.

Nā waiwai a me nā noi

ʻO ka pahu alumini paʻa-pore he porosity o 80 a 98%. Ua ʻoi aku kona ikaika ma mua o ka metala paʻa o ke kaumaha like. ʻO ka hoʻohana ʻana i ia mau mea he mana nui, ʻoi aku ka nui o ke ala o ka lawe ʻana i ka ʻoihana kaʻa, ka ʻoihana aerospace a me ka hana moku. ʻO ka hoʻohaʻahaʻa kaumaha e alakaʻi i ka mālama wahie a i ʻole hiki ke hoʻonui i ke kaumaha o ka ukana e lawe ʻia.

Hoʻopili ke ʻano porous o ka pahu alumini i ka ikehu hopena. Hiki ke hoʻohana ʻia kēia waiwai i ka wā o ka lawe ʻana e pale aku i nā kuʻi, e like me ka pale kaua a me ka pahū. ʻO ka ʻūhā metala e hoʻoheheʻe i ke kani. No laila, hiki ke hoʻohana ʻia nā panela pahu alumini e like me nā paia hoʻoheheʻe kani ma nā alanui a me nā ala kaʻa. Hiki ke hana maikaʻi ka hoʻohaʻahaʻa leo o nā hale kiʻiʻoniʻoni a me nā hale ʻaha mele. Ma muli o kona kaumaha haʻahaʻa a me ka ʻili nani, hoʻohana ʻia ka pahu alumini no ka hoʻolālā o loko a me waho.
