I kēia manawa,lole ulana ʻole i puhi ʻiahoʻohana nui ʻia ma ke kahua o nā mea kānana. Mai ka makahiki 1970, ua hoʻomohala ʻia a hoʻohana ʻia nā ʻano ʻenehana hoʻouku like ʻole me nā hoʻopiʻi electrostatic ma ke kāwili ʻana i nā fibers like ʻole. ʻO ka hopena koke ka hana electret electrostatic o kēia manawa. ʻO nā ʻano electret nui i kēia manawa e pili ana i ka electrostatic spinning, corona charging, friction electrification, thermal polarization a me ka low energy electron beam bombardment. Ma muli o nā ʻano hana electret electrostatic like ʻole (nā kaʻina hana) o nā mea, ʻokoʻa loa nā waiwai o nā kino electret i hoʻokumu ʻia.
ʻO kaʻoiaʻiʻo, ʻo ka hana kānana o ka meltblown nonwoven 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 fibers 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 pinepine nā mea kānana pīpī hoʻoheheʻe i ka hopena hoʻopiʻi electrostatic i ka lole pīpī hoʻoheheʻe ma o ke kaʻina hana koho electrostatic. Hiki i ka pono o ka kānana ke hiki i 99.9% a i 99.99% ma ka hoʻohana ʻana i ke ʻano electrostatic. KN95 maʻamau.
Hoʻohana ka mea kānana ea Electret i ka polarity o ke fiber ponoʻī e adsorb i ka lepo electrostatic a hopu i nā bacteria a me nā virus. 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 i puhi ʻia e ka electret melt-blown e hoʻoulu i kahi kahua electrostatic ikaika a me ke kahe microelectronics o nā bacteria, e hōʻino i kāna protein a me ka nucleic acid mutation, e luku i ka bacteria o ka ʻili, pepehi i ka bacteria, e 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 e pale ana i nā cell bacteria i ka hopena antibacterial.
ʻO ka hoʻoheheʻe ʻana - nā mea kānana jet electret e hopu i nā ʻāpana ma o ka hana pālua o ka pale mechanical a me ka adsorption electrostatic. Pili loa ke kū'ē mechanical i ke ʻano a me nā waiwai o nā mea: ke hoʻopiʻi ʻia ka lole pīpī hoʻoheheʻe ʻia e ka corona me kahi volta o kekahi mau haneli a i kekahi mau kilovolts, hoʻolaha nā fibers i loko o kahi pūnaewele o nā lua ma muli o ka repulsion electrostatic, a ʻoi aku ka nui o ka nui ma waena o nā fibers ma mua o ka nui o ka lepo, no laila e hana ana i kahi ʻano hāmama. Ke hele ka lepo ma o ka mea kānana jet hoʻoheheʻe ʻia, ʻaʻole hiki i ka hopena electrostatic ke huki wale i nā ʻāpana lepo i hoʻopiʻi ʻia, akā hopu pū i nā ʻāpana neutral polarized e ka hopena induction electrostatic. ʻO ke kiʻekiʻe o ka hiki electrostatic o ka mea, ʻoi aku ke kiʻekiʻe o ka nui o ka uku o ka mea, ʻoi aku ka nui o ka uku, ʻoi aku ka ikaika o ka hopena electrostatic. Hiki i ka hoʻokuʻu ʻana o Corona ke hoʻomaikaʻi nui i ka hana kānana o ka polypropylene melting - spraying cloth. ʻO ka hoʻohui ʻana o nā ʻāpana tourmaline hiki ke hoʻomaikaʻi maikaʻi i ka pono electret, hoʻonui i ka pono kānana, hoʻemi i ke kū'ē kānana, hoʻonui i ka nui o ka uku o ka fiber, a hoʻonui i ka hiki ke mālama o ka fiber net. ʻOi aku ka maikaʻi o ka hopena piha i ka wā e hoʻohui ʻia ai ka 6% tourmaline electret. Eia kekahi ʻO ka nui o nā mea electret e hoʻonui i ka neutralization o ka neʻe ʻana o ka mea lawe.
Ma luna e pili ana i: he aha ka hoʻolauna ʻana o ka lole ulana ʻole i ulana ʻia me ka hoʻoheheʻe ʻia, manaʻolana e loaʻa kekahi kōkua iā ʻoe; Hana mākouBEF99 i hoʻoheheʻe ʻia,kānana ʻana i ka hoʻoheheʻe ʻia,lole ulana ʻole i hoʻoheheʻe ʻia no ka pale maka;Welina mai e kūkākūkā ~
