I kēia manawa,ulana ʻole i hoʻoheheʻe ʻiaHoʻohana nui ʻia nā lole i ke kahua o nā mea kānana. Mai ka makahiki 1970, ua hoʻomohala ʻia a hoʻohana ʻia nā ʻano ʻenehana hoʻouku like ʻole a me nā kānana kū hoʻokahi me nā uku electrostatic ma ke kāwili ʻana i nā fibers like ʻole. ʻO ka hopena koke ka hana electret electrostatic o kēia manawa. I kēia manawa, ʻo nā ʻano electret e pili nui ana i ka milo electrostatic, ka hoʻouku corona, ka electrification friction, ka polarization thermal, ka hoʻopōkā electron low-energy, ka jet wai maʻemaʻe, a pēlā aku. Ma muli o nā kaʻina hana electret electrostatic like ʻole o nā mea, ʻokoʻa loa nā waiwai o nā kino electret i hoʻokumu ʻia, a he ʻokoʻa ka hoʻomaikaʻi ʻana i ka hana kānana a me ka hoʻomau electrostatic.
ʻO kaʻoiaʻiʻo, ʻo ka hana kānana o nā lole nonwoven meltblown he emi wale nō ma mua o 70%, a ʻaʻole lawa ka hilinaʻi wale ʻana i ka hopena pale mechanical o ka hōʻuluʻulu ʻekolu-dimensional o nā fiber ultrafine me nā fibers maikaʻi, nā lua liʻiliʻi a me ka porosity kiʻekiʻe. A i ʻole, ʻo ka hoʻonui wale ʻana i ka mānoanoa o ke kaumaha gram mea e hoʻonui nui i ke kūpaʻa kānana. No laila, hoʻohui ka hoʻoheheʻe ʻana a me ka pīpī ʻana i nā mea kānana i ka hopena hoʻopiʻi electrostatic i ka hoʻoheheʻe ʻana a me ka pīpī ʻana i ka lole ma o ke kaʻina hana electrostatic electoral-electrode, a hoʻohana i ke ʻano electrostatic e hoʻomaikaʻi i ka pono kānana, hiki ke hiki i ka% a i ka%. ʻO ia hoʻi e hoʻokō i ke kūlana KN95 a i ʻole ma luna.
Hoʻohana ka mea kānana ea Electret i ka polarity o ke fiber ponoʻī e hoʻopili i ka lepo electrostatic a hopu i nā bacteria a me nā virus. ʻOkoʻa ka uku uila o ka electret o ka polypropylene fused jet fiber mai ke kāʻei friction o nā mea maʻamau. ʻAʻole ʻepekema ke kaha kiʻi i nā ʻāpana pepa e hoʻoholo ai inā ua hoʻopiʻi ʻia ka spray i hoʻoheheʻe ʻia a inā paha he hana kānana ka mask ma o ke ʻano o ka friction electrification. ʻO ka electrification friction kahi uku manawa pōkole, ʻo ia ka hōʻiliʻili ʻana o ka uku ʻili i kahi hanana manawa pōkole. ʻO ka uku friction ka uku polarized ʻili maikaʻi a maikaʻi ʻole, ʻoiai ʻo ka uku fiber electret ka uku kūloko keu i hoʻohui ʻia ma ka hoʻopili ʻana i ka uku voltage kiʻekiʻe i ka wā o ke kaʻina hana electret. Hoʻopuehu ʻia kēia mau uku i loko o ka loko porous o ka fiber ultrafine i hoʻoheheʻe ʻia ma ke ʻano o nā nanoparticles master electret. ʻO ke kūpaʻa wai o ka mea jet i hoʻoheheʻe ʻia a me ka pale o ka fiber ultrafine e hoʻopaʻa paʻa i kēia mau uku i loko. Ke komo wale nā ʻāpana maikaʻi i loko o ka papa jet i hoʻoheheʻe ʻia, hoʻomaka ka hopena electrostatic a me ke ʻano o ka fiber ultrafine e pāʻani i kahi kuleana.
ʻO ka mea i kapa ʻia he uila static no ka mea ʻo ka mea polypropylene molten jet ponoʻī he insulating, he ʻano mea electpoles nō hoʻi, no laila ʻaʻole e neutralized randomly ka uku, hoʻopau randomly. Mālama ʻia ka uku hoʻokuʻu voltage kiʻekiʻe loa i loko o ka fiber no ka manawa lōʻihi me ka lawa ʻana o ka uila. Eia kekahi, ʻo ia ka noho pū ʻana o nā uku he nui, ʻaʻole he ʻano uku i hana ʻia e ka friction. No laila, ʻaʻole hiki i ka macro adsorption ke hōʻike pololei i ka hana microscopic charge. Hoʻohana ʻia ka porosity kiʻekiʻe a me nā waiwai electret electrostatic hāmama o nā fibers ultrafine e hāʻawi i ka pono kiʻekiʻe a me ka maikaʻi kānana haʻahaʻa. Ma ke ʻano hana antibacterial loa, ʻo ka lole electret melt-blown e hoʻoulu i kahi kahua electrostatic ikaika a me ke kahe microelectronics o ka bacteria, e hōʻino i kāna protein a me ka nucleic acid mutation, e luku i ka bacteria o ka ʻili o ka ʻili, pepehi i ka bacteria, hoʻokuʻu i nā ions maikaʻi ʻole tourmaline ponoʻī i ālai ʻia kekahi mau kaʻina hana metabolic microbial bacteria, me ka ʻōnaehana hanu, ka hana o ka enzyme, ka hoʻoili nui ʻana mai ka paia cell, no laila ke kāohi nei i nā cell bacteria he hopena antibacterial.
Hemea hana lole ulana ʻole i hoʻoheheʻe ʻia, e ʻoluʻolu e kūkākūkā me mākou ~
