Nā ʻano hiʻohiʻona o nā mea alumini foam

Hoʻokumu ʻia ka pahu alumini me kahimetala aluminimea matrix a me nā pores. ʻO nā ʻāpana hoʻonohonoho o ka pahu alumini e pili ana i ke anawaena pore, porosity a i ʻole pili pili, pore pōʻai, a me kahi kikoʻī kikoʻī. Hiki ke hoʻokaʻawale ʻia ka pilina ma waena o nā hale pore e like me ka open-cell alumini foam apahu pahu alumini paʻa, ʻO ka puʻupuʻu pore o ka pahu alumini he mea maʻamau, akā hiki i nā kaʻina hana kikoʻī ke hoʻokō i kahi hoʻolaha hoʻonohonoho. ʻO ke ʻano o nā pores hiki ke hoʻopili ʻia i ka hale paʻa, kahi ʻano hāmama, a i ʻole ka hui ʻana o nā mea ʻelua. ʻO nā pores oʻūhā alumini puka hāmamaHoʻohui ʻia, ʻoiai ʻo nā pores o ka pahu alumini paʻa paʻa he kūʻokoʻa a hoʻokaʻawale ʻia mai kekahi i kekahi i hiki ke manaʻo ʻia ka pahu alumini ma ke ʻano he mea hoʻohui o ʻelua mau pae: ka alumini matrix a me nā pores. ʻO ka hale paʻa paʻa: ua paʻa loa nā paia pore i kekahi i kekahi, a ua uhi ʻia ke kinoea i loko o nā pores, he kani maikaʻi a me nā hopena insulation wela a hoʻohana mau ʻia i ka absorption ikehu, anti-collision, a me nā māla ʻē aʻe. ʻO ka wehe ʻana o ka cell cell: pili nā paia pore, me ka permeability maikaʻi o ka ea a me ka conductivity wai, kūpono no ka kānana ʻana, ka wela wela, a me nā hiʻohiʻona ʻē aʻe. No ka mea e hoʻoholo pololei nā ʻāpana o ka alumini foam i ka hana o ka alumini foam, i nā noi kūpono, pono e koho ʻia nā mea alumini foam me nā ʻāpana kūpono e like me nā noi like ʻole. Ke hoʻohālikelike ʻia me nā mea metala kahiko, ʻike ʻia ka pahu alumini e ka nui pore nui (pore nui D = 0.2 mm a 8 mm), porosity kiʻekiʻe (porosity 63% a 90%), a me ka haʻahaʻa haʻahaʻa. ʻO ke kino iwi opahu aluminihōʻike i kahi mahele reticular ʻekolu-dimensional, i loko o nā ʻāpana paʻa o ka alumini alumini. Hāʻawi kēia reticulation i nā waiwai mechanical maikaʻi loa, e like me ka ikaika kikoʻī kiʻekiʻe a me ka absorption ikehu maikaʻi. ʻO ka ʻili o waho o ka pahu alumini ka mea maʻamau me nā pores i ʻike ʻia, akā hiki ke hoʻomaikaʻi ʻia ka maikaʻi o ka ʻili ma o ka mālama ʻana (e laʻa, ka uhi ʻana, ka mīkini).

ʻO nā mea a pau, ʻo nā hiʻohiʻona o ka pahu alumini kona porosity, māmā a me ka ikaika kiʻekiʻe, a me ka ʻiʻo reticulated ʻekolu-dimensional. Hoʻoholo kēia mau mea hoʻolālā i kāna noi ākea ma nā ʻano o ka acoustic a me ka insulation thermal, ka hoʻoulu ʻana i ka ikehu, ka pale ʻana i ka hopena, ka kānana, a me ka hana māmā.

ʻO nā hiʻohiʻona o ka alumini puaʻa: (a) ka alumini puaʻa hāmama; (b) ka alumini hoʻoheheʻe ʻia
