Aia he 5 mau palena nui o kahuʻa metalamea:

1. mea metala kumu, ʻo ia hoʻi, kametala porous foamhana ʻia nā mea metala, i kēia manawa, kā mākou noiʻi nui a me ka hoʻomohala ʻana a me ka hana ʻana o nā meanickel foam, keleawe, hao, hao-nickel alloy, copper-nickel alloy, a me nā ʻano like ʻole o ka mālama ʻana i ka wela o ka ʻili o ka mea e like me ka chromium infiltration.

2. mānoanoa, i kēia manawa, nā mea i hāʻawi ʻia ʻo ia nā mea pepa a pau, ʻo ka mānoanoa he 0.7mm-25mm.

3. PPI, Pākē no ka helu o nā puka i kēlā me kēia ʻīniha, ʻo ka pākuʻi he ʻāpana kūikawā o ka mea puna puna, e hōʻike ana i ka helu o nā cell sponge ma kēlā me kēia ʻīniha lōʻihi o ka lōʻihi pololei ma, ʻo ka ʻike intuitive ka nui o ka waiwai PPI, ʻoi aku ka liʻiliʻi. hiki ke ʻike ʻia nā lua ma ka ʻili o ka mea me ka maka ʻōlohelohe, hāʻawi nui mākou i kēia manawa i ka 10PPI a i ka 140PPI ma waena o nā mea, e pili ana i nā palena o ka sponge. substrate, PPI nā palena ma nā hoʻonui o 10, e like me mākou Hāʻawi mākou i 10, 20, 30, 40 a me nā ʻāpana PPI ʻē aʻe o ka mea, akā ʻaʻole hāʻawi i ka PPI o 23, 38 a me nā mea ʻē aʻe.

4. density, mahele ʻia ka nui i ka nui a me ka ʻili o ka ʻili, ʻo ka nui ka nui o ke kaumaha o ka mea i loko o ka leo paʻa, e like me 1000g / m3, ʻoi aku ka nui o ke kaumaha o ka huahana ma kahi paʻa ma lalo o ka mānoanoa i kuhikuhi ʻia, e like me 10mm mānoanoa, 1600g/m2; hoʻoholo ka paʻakikī i ka ikaika o ka mea.

5. wahi, i kēia manawa, ʻo ka ʻāpana o ka ʻāpana maʻamau o nā mea i hāʻawi ʻia a hiki i 500X500mm, (koe wale no ka hana nui o nā mea kāʻei mau, pono nā ʻāpana ʻē aʻe i kahi kauoha paʻa, hoʻolālā mākou i nā mea hana hou).

Inā pono ʻoe e kūʻai i nā huahana metala foam, pono ʻoe e hoʻoholo i nā ʻāpana ʻelima ma luna aʻe i mea e hoʻoholo ai i nā kikoʻī kikoʻī a me ke kumukūʻai o ka metala foam.
