Hōʻike ka N i N95 masks ʻaʻole kū i ka ʻaila, ʻo ia hoʻi, ʻaʻole kū i ka ʻaila; Hōʻike ka helu i ka pono kānana ke hoʻāʻo ʻia me 0.3 micron particles, a ʻo 95 ka mea hiki ke kānana i ka liʻiliʻi he 95% o nā mea liʻiliʻi e like me ka maʻi maʻi influenza, lepo, pollen, haze, a me ka uahi. E like me nā masks lapaʻau lapaʻau, ʻo ke ʻano nui o nā masks N95 he ʻekolu mau ʻāpana: kahi papa moisture-proof surface, kahi kānana waena a me kahi papa adsorption, a me kahi papa ʻili i loko. ʻO ka mea maka i hoʻohana ʻia ʻo ia ka lole polypropylene meltblown kiʻekiʻe. No ka mea he mau lole hehee lakou a pau, he aha ke kumu o ka hiki ole ana o ka filtration i ka pono?
ʻO nā kumu no ka maikaʻi kānana substandard o ka lole meltblown mask
ʻO ka hana kānana o ka meltblown non-woven lole ponoʻī ma lalo o 70%. ʻAʻole lawa ka hilinaʻi wale ʻana i ka hopena mechanical barrier o nā ʻāpana fiber 3-dimensional o nā meltblown ultrafine fibers me nā fibers maikaʻi, nā liʻiliʻi liʻiliʻi, a me ka porosity kiʻekiʻe. A i ʻole, ʻo ka hoʻonui wale ʻana i ke kaumaha a me ka mānoanoa o ka mea e hoʻonui nui ai i ka pale kānana. No laila, hoʻohui pinepine ʻia nā mea kānana e hoʻoheheʻe ʻia i ka electrostatic i ka lole i hoʻoheheʻe ʻia ma o ke kaʻina o ka electrostatic polarization, me ka hoʻohana ʻana i nā ʻano electrostatic e hoʻomaikaʻi ai i ka pono kānana, hiki ke hiki i 99.9% a 99.99%. ʻO ia hoʻi, hiki i ke kūlana N95 a i luna paha.
Ke kumu o ka hoʻoheheʻe ʻana i ka lole pulu kānana
ʻO ka lole i hoʻoheheʻe ʻia i hoʻohana ʻia no nā masks maʻamau N95 e hopu nui i nā ʻāpana ma o ka hopena pālua o ka mechanical barrier a me ka electrostatic adsorption. ʻO ka hopena mechanical barrier pili pili loa i ke ʻano a me nā waiwai o ka mea: i ka wā e hoʻopiʻi ʻia ai ka meltblown fabric e ka corona me ka volta o nā haneli he mau tausani volts, hoʻoheheʻe ʻia nā fibers i loko o kahi pūnaewele o nā pores ma muli o ka electrostatic repulsion. Ke hele ka lepo i ka mea kānana hoʻoheheʻe ʻia, ʻaʻole wale ka hopena electrostatic e huki pono i nā ʻāpana lepo i hoʻopaʻa ʻia, akā hopu pū kekahi i nā ʻāpana kū ʻole polarized ma o ka hopena induction electrostatic. ʻOi aku ka kiʻekiʻe o ka pono electrostatic o ka mea, ʻoi aku ka kiʻekiʻe o ka nui o ka hoʻopiʻi o ka mea, ʻoi aku ka nui o nā kumu kiko e lawe ai, a ʻoi aku ka ikaika o ka hopena electrostatic. Hiki i ka hoʻokuʻu ʻana o Corona ke hoʻomaikaʻi maikaʻi i ka hana kānana o ka lole polypropylene meltblown. ʻO ka hoʻohui ʻana i nā ʻāpana tourmaline hiki ke hoʻomaikaʻi maikaʻi i ka polarizability, hoʻonui i ka pono kānana, hoʻemi i ka pale ʻana i ka kānana, hoʻonui i ka nui o ka ili o ka fiber, a hoʻonui i ka hiki ke mālama ʻia o ka pūnaewele fiber.
ʻO ka hoʻohui ʻana i ka 6% tourmaline i ka electrode he hopena maikaʻi loa. ʻO ka nui o nā mea polarizable hiki ke hoʻonui i ka neʻe a me ka neutralization o nā mea lawe uku. Pono e loa'a i ka nanometer a i 'ole ka micro nanometer ka nui a me ke kaulike. Hiki i ka polar masterbatch maikaʻi ke hoʻomaikaʻi i ka hana wili me ka ʻole o ka pili ʻana i ka nozzle, hoʻomaikaʻi i ka pono kānana, pale i ka hoʻohaʻahaʻa electrostatic, hoʻemi i ka pale ʻana o ka ea, hoʻonui i ka nui a me ka hohonu o ka hopu ʻana, hoʻonui i ka nui o nā kumu i hoʻopaʻa ʻia i loko o ka fiber aggregates, a mālama i nā koina i hopu ʻia i kahi kūlana haʻahaʻa haʻahaʻa.
Ke kaʻina hana polarization electrostatic puhi
ʻO ke kaʻina hana o ka hoʻoheheʻe electrostatic hoʻoheheʻe ʻia e hoʻohui i nā mea inorganic e like me tourmaline, silicon dioxide, a me zirconium phosphate i ka PP polypropylene polymer ma mua. A laila, ma mua o ka ʻōwili ʻana i ka lole, hoʻopiʻi ʻia ka mea hoʻoheheʻe ʻia e hoʻokahi a ʻoi aʻe paha o ka hoʻokuʻu ʻana o ka corona me ka hoʻohana ʻana i ka uila uila uila o 35-50KV i hana ʻia e kahi mea hana electrostatic. Ke hoʻohana ʻia ka uila kiʻekiʻe, hoʻopuka ka ea ma lalo o ka piko o ka nila i ka corona ionization, ka hopena o ka hoʻokuʻu ʻana i ka wahi. Hoʻokomo ʻia nā mea lawe uku ma ka ʻili o ka lole i hoʻoheheʻe ʻia ma o ka hana o ke kahua uila, a ʻo kekahi o lākou e hoʻopaʻa ʻia e ka pahele o nā ʻāpana makuahine paʻa, e hana ana i ka lole hoʻoheheʻe ʻia i mea kānana no ka electrode. ʻOi aku ka haʻahaʻa o ka volta i kēia kaʻina corona i hoʻohālikelike ʻia me ka hoʻokuʻu ʻana me ka volta kiʻekiʻe ma kahi o 200Kv, ka hopena o ka hana ozone. ʻO ka hopena o ka hoʻouka ʻana i ka mamao a me ka hoʻouka ʻana i ka volta he counterproductive. Ke hoʻonui nei ka mamao o ka hoʻouka ʻana, e emi ana ka nui o ka uku i hopu ʻia e ka mea.
Pono ka lole meltblown electrified
1. Hoʻokahi o nā mea hoʻoheheʻe i puhi ʻia
2. Electrified masterbatch
3. ʻEhā mau pūʻulu o nā mea hoʻokuʻu electrostatic kiʻekiʻe
4. Mea ʻoki ʻoki
Pono e mālama ʻia ka lole hoʻoheheʻe ʻia me ka wai a me ka wai
Ma lalo o nā kūlana mahana a me ka haʻahaʻa maʻamau, ʻoi aku ka maikaʻi o ka mālama pono ʻana o ka PP melt blown polarized material. Eia naʻe, i ka wā o ka laʻana i loko o kahi haʻahaʻa haʻahaʻa kiʻekiʻe, nui ka nui o ka pohō o ka uku ma muli o ka hopena uku o nā hui polar i loko o nā molekole wai a me nā ʻāpana anisotropic i ka lewa ma nā uku ma nā fibers. Hoʻemi ka uku me ka hoʻonui ʻana i ka haʻahaʻa a ʻoi aku ka wikiwiki. No laila, i ka wā o ka lawe ʻana a me ka mālama ʻana, pono e mālama ʻia ka lole hoʻoheheʻe ʻia a pale i ka hoʻopili ʻana me nā wahi haʻahaʻa kiʻekiʻe. Inā ʻaʻole mālama pono ʻia, paʻakikī nā masks i hana ʻia e hoʻokō i nā kūlana.
Dongguan Liansheng Non ulana 'enehana Co., Ltd.ua hoʻokumu ʻia ma Mei 2020. He ʻoihana hana lole lole ʻaʻole i ulana nui ʻia e hoʻohui i ka noiʻi a me ka hoʻomohala ʻana, ka hana ʻana, a me ke kūʻai aku. Hiki iā ia ke hana i nā kala like ʻole o ka PP spunbond non-woven fabrics me ka laulā o lalo o 3.2 mika mai 9 grams a 300 grams.
