*Nā hiʻohiʻona hoʻoneʻe lepo o ka pahu kānana

1. Ka kānana hohonu

He ʻuʻuku kēia ʻano mea kānana, a he nui ka ʻokoʻa ma waena o ka fiber a me ka fiber.No ka laʻana, he 20-100 μm ka lua o ka polyester needled feel.I ka 1 μm ka nui o ka nui o ka lepo, i ka wā o ka kānana ʻana, e komo kahi ʻāpana o nā ʻāpana maikaʻi i ka mea kānana a noho ma hope, a e pakele ka ʻāpana ʻē aʻe ma o ka mea kānana.ʻO ka hapa nui o ka lepo e pili ana i ka ʻili o ka mea kānana e hana i kahi papa kānana, kahi e kānana ai i ka lepo i loko o ke kahe o ka lepo.ʻO nā'āpana liʻiliʻi e komo ana i ka mea kānana e hoʻonui i ke kū'ēʻana a paʻakikī i ka mea kānana a hiki i ka wā i'ōpalaʻia.Kapa ʻia kēia ʻano kānana i ka kānana hohonu.

2. Ili kānana

Ma ka ʻaoʻao o ka mea kānana manuahi e hoʻopili ai i ke kinoea i loko o ka lepo, ua hoʻopaʻa ʻia kahi ʻāpana microporous film, a ʻo ke āpau ma waena o nā fibers he 0.1-0.2 μm wale nō.Inā he 1 μm ka nui o ka lepo o ka lepo, kokoke i ka pauka a pau e pani ʻia ma ka ʻili o ka membrane microporous, ʻaʻole hiki i ka lepo maikaʻi ke komo i loko o ka mea kānana, ua kapa ʻia kēia ʻano kānana.ʻO ka kānana ʻili he ʻenehana kānana kūpono, hiki iā ia ke hoʻomaikaʻi hou i ka maikaʻi o ka wehe ʻana i ka lepo, hoʻemi i ka nalowale o ke kaomi o ka mea kānana, a mālama nui i ka hoʻohana ʻana i ka mana o ka ʻōnaehana wehe lepo.Inā lahilahi ka fiber o ka mea kānana, ma hope o kahi kaʻina hana kūikawā, ʻaʻole hiki iā ia ke mālama wale i kahi degere o ka ea permeability, akā e hoʻemi hoʻi i ke āpau ma waena o nā fibers.ʻOiai ʻaʻole i uhi ʻia kēia mea kānana ma luna o ka ʻili, he paʻakikī i nā ʻāpana maikaʻi o ka lepo ke komo i ka mea kānana.Hiki ke hoʻohana ʻia kēia ʻano mea kānana me ka ʻole o nā membrane lehulehu no ka kānana ʻili.ʻO ka mea kānana i hoʻohana ʻia no ka hana ʻana i ka pahu kānana, aia nā mea kānana kānana he nui a me ka media filter non-multi-membrane, inā hiki ke hoʻokō ʻia ka kānana ili ma muli o ka mea kānana i koho ʻia.
