He metala paha ka huʻa metala?

ʻO ka pahu metala kahi mea metala me nā waiwai kūikawā, nona nā waiwai metala a me nā waiwai, no laila ua kapa ʻia ka inoa metala. No laila, he mea metala ʻo foam?
ʻAe ka pane. Hana ʻia ka metala foam i nā mea metala, nona nā waiwai o ka metala e like me ka uila conductivity, thermal conductivity, ikaika a pēlā aku. I ka manawa like, he nui ka nui o nā pores liʻiliʻi i loko o ka metala, e hana ana i kahi ʻano like me ka foam, ka mea e hana ai ka pahu metala i nā waiwai o ke kaumaha māmā, ka ikaika kikoʻī kiʻekiʻe, ka insulation wela maikaʻi a pēlā aku.
Na waiwai a me na ano
1. Ke kaumaha māmā a me ka ikaika kiʻekiʻe
He kiʻekiʻe loa ka ikaika kikoʻī a me ka modulus kikoʻī o ka mea metala foam, he liʻiliʻi kona ʻano, akā kiʻekiʻe loa ka ikaika a me ka ʻoʻoleʻa, e lilo ia i mea hana māmā māmā.
2.Good thermal paʻa
Loaʻa i nā mea hoʻoheheʻe metala ke kūpaʻa wela maikaʻi a hiki ke mālama i ko lākou mau waiwai kumu i nā wela kiʻekiʻe, kahi e hiki ai ke hoʻopili iā lākou i nā wahi wela kiʻekiʻe.
3. Kiʻekiʻe kiko'ī ili
Loaʻa i nā mea metala foamed kahi ʻāpana kikoʻī kikoʻī kiʻekiʻe loa, e hāʻawi iā lākou i ka adsorption maikaʻi a me nā waiwai insulation kani.
Nā kahua noi
1.Aerospace.
Hiki ke hoʻohana ʻia nā mea metala foamed e hana i nā mea hana no nā mokulele a me nā pōhaku, e like me nā ʻēheu, fuselages a me nā pahu mīkini. Loaʻa i kēia mau ʻāpana nā hiʻohiʻona māmā a me ka ikaika kiʻekiʻe, hiki ke hoʻomaikaʻi i ka hana lele a me ka pono o ka wahie o ka mokulele.
2. Kūkulu.
Hiki ke hoʻohana ʻia nā mea hoʻoheheʻe metala no ka hana ʻana i nā panela pā kani, nā panela hale a me nā papa hale, a me nā mea ʻē aʻe.
3. ʻOihana kaʻa: Hiki ke hoʻohana ʻia nā mea metala foam i ka hana ʻana i nā mīkini kaʻa.
Hiki ke hoʻohana ʻia nā mea hao metala no ka hana ʻana i nā puʻupuʻu kaʻa, nā papa, nā noho a me nā mea ʻē aʻe, hiki ke hoʻomaikaʻi i ka ikaika a me ka hōʻoluʻolu o nā kaʻa.
4. kahua mālama kaiapuni.
Loaʻa nā mea hoʻoheheʻe metala i nā waiwai adsorption maikaʻi loa, hiki ke hoʻohana ʻia no ka mālama ʻana i ka wai ʻino, ka ʻōpala a me nā metala kaumaha a me nā mea ʻino ʻē aʻe, he ākea ka nui o nā noi kaiapuni.
Hiki ke hoʻomaikaʻi hou ʻia ka pahu metala e ka mālama ʻana i ka ʻili a me ka ʻenehana hoʻololi e hoʻomaikaʻi hou i kāna hana a me ka laulā noi. No ka laʻana, hiki ke uhi ʻia, hoʻopaʻa ʻia a me nā kaʻina hana ʻē aʻe e hoʻomaikaʻi ai i kāna anti-corrosion, wear-resistant, electrically conductive a me nā waiwai ʻē aʻe, i hiki ke hoʻohana ʻia i kahi ākea ākea. Ma ke ʻano he mea māmā a me ka ikaika kiʻekiʻe, ʻoi aku ka nui o nā mea metala foam i ka nui o nā manaʻo noi a me ka hiki ke hoʻomohala. Me ka holomua o ka ʻepekema a me ka ʻenehana a me ka hoʻonui ʻana i nā wahi noi, e pāʻani nui nā mea metala foam i ka hana koʻikoʻi i ka wā e hiki mai ana.
