Puhu keleawe 20PPI, >95% maemae, mānoanoa 12.5mm, ʻoki ʻia i ke ʻano donut OD 40mm, ID 7mm
ʻO kēia huahana e hana i ka noiʻi ʻana i nā mea hoʻololi.

Huʻa keleawe
10PPI, ʻO ke anawaena o waho= 210mm I loko o ka lua waena d = 171mm ʻO kēlā me kēia arc he ¼ o ke kaha kiʻi mua ʻO ka mānoanoa pua 25 mm.
10PPI, Anawaena o waho= 29.4mm I loko o ka lua waena d = 4 mm I loko o ka puka hope d = 3.2 ± 0.1 mm Ka mamao ma waena o nā puka kikowaena z = 7.5 mm Ka mānoanoa o ka pua 25 mm
ʻO ka huʻa kahi mea a mākou e hoʻohana ai i nā reactor kemika e hoʻomaikaʻi i ka hoʻoili wela.

Loaʻa iā ia ka ea permeability kiʻekiʻe, kokoke i nā pores pili āpau, kahi ākea ākea nui o nā pores, a me nā mea liʻiliʻi liʻiliʻi.
Hoʻohana ʻia ka pahu metala i ka hana ʻana i ka hoʻomaʻemaʻe, kānana, kākoʻo catalytic, electrodes a me nā mea hana ʻē aʻe i ka petrochemical, aerospace, a me ka pale ʻana i ke kaiapuni.

Ke hoʻohālikelike ʻia me ka metala porous sintered maʻamau, ʻoi aku ka nui o ka porosity o ka mea metala i loaʻa i nā pores foam a ʻoi aku ka nui o ka pore, hiki ke hiki i 7 mm. No ka mea, ʻo ka pahu metala kahi mea i hoʻohui ʻia i ʻelua ʻāpana i haku ʻia me kahi ʻāpana metala matrix skeleton hoʻomau a me kahi pore dispersed phase a i ʻole ka hoʻomau mau ʻana, hilinaʻi kona mau waiwai i ka matrix metala i hoʻohana ʻia, porosity a me ka hoʻolālā pore, a pili i ke kaʻina hana hoʻomākaukau. ʻO ka maʻamau, hoʻemi ʻia nā waiwai metala me ka piʻi ʻana o ka porosity, a ʻo kona conductivity uila a me ka conductivity thermal kekahi emi nui. Ke hoʻemi ʻia ka pahu metala, ma muli o ka hoʻonui ʻia o ka ikaika a me ka hopena paʻakikī o nā mea i hoʻokumu ʻia e ka hāʻule ʻana o nā pores, ʻoi aku ka maikaʻi o ka ʻona metala i nā hiʻohiʻona absorption ikehu.
