Nā Pākuʻi Paʻa Māmā | Nā ʻĀpana Hoʻohuʻi Kiʻekiʻe no ka Kelepona Kelepona
ʻO ka pahu pahu he mea hoʻoheheʻe ʻia me ʻekolu mau ʻano porosity: pores gel, nā pores capillary a me nā pores ea [82]. ʻO nā waiwai ikaika o ka pahu pahu e pili pono ana i ka nui a me ka hāʻawi ʻana i kēia mau pores. He kiʻekiʻe ka permeability a me ka ratio ikaika-a-kaumaha maikaʻi. He mea hana hoihoi loa ia, a hiki ke hoʻohana ʻia i nā noi e like me nā tunnels lalo, papahele a me na paia.
Hana ʻia ka ʻōhū ma ka hoʻohana ʻana i kahi protein a i ʻole synthetic foaming agent i hoʻoheheʻe ʻia i ka wai. ʻOi aku ka kiʻekiʻe o ka hoʻonui ʻana o ka mea hoʻohua ma mua o ka wai, ka mea e hiki ai ke hana i ka nui o ka pua. Hoʻoulu ʻia ka ʻōhū i loko o ke keʻena hui me ka ea compressor, ʻo ia ka mea e hoʻonui ai i nā ʻōhū a hana i kahi ʻano o nā ʻōmole pili. Hoʻohui ʻia ka ʻūhā me nā mea kumu ʻē aʻe e like me ka lehu lele, lepo i hoʻopaʻa ʻia i ka umu ahi (GGBFS) a me ka mahu silika.
E ninini ʻia ka ʻōpala i loko o nā pahu kila a uhi ʻia me ka cellophane e pale ai i ka hoʻoheheʻe ʻana o ka wai. Hoʻāʻo ʻia nā ʻāpana paʻakikī no ka ikaika compressive. Hōʻike nā hopena i ka manaʻo o ka pāpaʻi i ka hopena pololei i kona ikaika paʻa, a ʻo ka mānoanoa kiʻekiʻe e alakaʻi i ka ikaika compressive haʻahaʻa. ʻO ka nui o ka pore a me ka hāʻawi ʻana i ka ʻūhā kekahi mea nui, akā, aia kahi kūʻai ma waena o ka nui o ka pore a me ka ikaika. ʻOi aku ka maikaʻi o nā hiʻohiʻona ikaika.
