1. Hoʻopaʻa i nā ʻāpana lepo i ka lewa, e neʻe me ka neʻe inertial a i ʻole ka neʻe Brownian random a i ʻole ka neʻe ʻana e kekahi ikaika kahua. Ke pā ka ʻenekini ʻāpana i nā mea ʻē aʻe, aia ka ikaika van der Waals ma waena o nā mea (molecular a me molecular, ʻO ka ikaika ma waena o ka pūʻulu mole a me ka pūʻulu mole ka mea e pili ai nā ʻāpana i ka ʻili o ka fiber. ʻO ka lepo e komo ana i ka mea kānana ʻoi aku ka nui o ka paʻi ʻana i ka waena, a pili ia i ka wā e paʻi ai i ke ʻano. paʻa.
2. Ke neʻe nei ka lepo inertia a me ka diffusion i ka inertia i ka ea. I ka wā e ʻike ai i nā fiber disorderly, hoʻololi ka ea i ke ala, a hoʻopaʻa ʻia nā ʻāpana e ka inertia, e paʻi i ka fiber a hoʻopaʻa ʻia. ʻO ka nui o ka ʻāpana, ʻoi aku ka maʻalahi o ka hopena, a ʻoi aku ka maikaʻi o ka hopena. Hoʻohana ʻia ka lepo ʻāpana liʻiliʻi no ka neʻe ʻana o Brownian. ʻOi aku ka liʻiliʻi o nā ʻāpana, ʻoi aku ka ikaika o ka neʻe ʻana i nā ʻano like ʻole, ʻoi aku ka nui o ka manawa e paʻi i nā mea pale a ʻoi aku ka maikaʻi o ka hopena kānana. Hoʻohana nui ʻia nā ʻāpana liʻiliʻi ma mua o 0.1 micron i ka lewa no ka neʻe Brownian, a liʻiliʻi nā ʻāpana a maikaʻi ka hopena kānana. Hoʻohana nui ʻia nā ʻāpana nui ma mua o 0.3 microns no ka neʻe inertial, a ʻoi aku ka nui o nā ʻāpana, ʻoi aku ka kiʻekiʻe o ka pono. ʻAʻole maopopo ʻo ka diffusion a me ka inertia ka mea paʻakikī loa e kānana. I ka ana ana i ka hana ana o ke kiʻekiʻe-efficiency kānana, ua hoakaka pinepine ia e ana i ka lepo waiwai waiwai i ka loa paakiki e ana.
3. Hana Electrostatic No kekahi kumu, hiki ke hoʻopiʻi ʻia nā fibers a me nā ʻāpana me kahi hopena electrostatic. Hiki ke hoʻomaikaʻi nui ʻia ka hopena kānana o ka mea kānana electrostatically charged. Ke kumu: Hoʻololi ka uila i ka lepo i kona alahele a pā i kahi mea pale. Hoʻopaʻa paʻa ka lepo i ka uila ma luna o ka uila. ʻO nā mea hiki ke lawe i ka uila paʻa no ka manawa lōʻihi i kapa ʻia ʻo "electret". ʻAʻole hoʻololi ʻia ka pale ʻana o ka mea ma hope o ka uila static, a ʻike maopopo ʻia ka hopena kānana. ʻAʻole koʻikoʻi ka uila static i ka hopena kānana, akā hoʻokani wale i kahi hana kōkua.
4. Ke kānana kemika ʻO nā kānana kemika nui loa e hoʻopili i nā molekele kinoea ʻino. Aia ka nui o nā micropores i ʻike ʻole ʻia i loko o ka mea kalapona i hoʻāla ʻia, nona kahi wahi adsorption nui. I ke kalapona i ho'āla 'ia o ka nui o ka palaoa raiki, 'oi aku ka nui o ka wahi i loko o nā micropores ma mua o 'umi mau mika square. Ma hope o ka hoʻopili ʻana o nā molekala manuahi me ke kalapona i hoʻāla ʻia, hoʻoheheʻe lākou i loko o ka wai i loko o nā micropores a noho i loko o nā micropores ma muli o ke kumu capillary, a ua hui pū kekahi me ka mea. ʻO Adsorption me ka loaʻa ʻole o kahi hopena kemika nui i kapa ʻia ʻo physical adsorption. Hoʻohana ʻia kekahi o nā kalapona i hoʻāla ʻia, a ua hoʻopili nā ʻāpana adsorbed me ka mea e hana ai i mea paʻa a i ʻole kinoea kino ʻole, i kapa ʻia ʻo Huai adsorption. E hoʻonāwaliwali mau ʻia ka mana adsorption o ke kalapona i hoʻohana ʻia i ka wā o ka hoʻohana ʻana i ka mea, a i ka wā e nāwaliwali ai i kekahi ʻano, e ʻoki ʻia ka kānana. Inā he adsorption kino wale nō, hiki ke hana hou ʻia ke kalapona i hoʻāla ʻia e ka hoʻomehana ʻana a i ʻole ka mahu e hoʻoneʻe i nā kinoea ʻino mai ke kalapona hoʻāla ʻia.
