ʻAʻohe waiwai o nā mea Meltblown ma ka honua holoʻokoʻa a piha nā hale hana a pau, akā aia kahi mea kānana kiʻekiʻe e pani ana i nā mea meltblown.ʻO ia ka PTFE (polytetrafluoroethylene)!
ʻO ka hoʻohana ʻana i ka mask he ala koʻikoʻi a maikaʻi hoʻi e hoʻokaʻawale i ka maʻi maʻi a pale i nā pūʻulu nāwaliwali.I kēia manawa, hiki ke hoʻohana ʻia nā masks e hoʻokaʻawale i ka bacteria a me nā ʻāpana PM2.5 i ʻelua ala:
(1) Electrostatic adsorption, he hana hoʻokaʻawale ikaika, hoʻohana i ka ikaika electrostatic ma waena o nā fibers i ka papa waena o ka mask e adsorb bacteria a me nā mea liʻiliʻi e hoʻokō ai i ka noho kaʻawale a me ka pale;
(2) ʻO ka hoʻokaʻawale kino kahi ʻano hoʻokaʻawale passive, e hoʻohana ana i ke ʻano pore liʻiliʻi o ka mask ponoʻī e pale i ka hoʻouka ʻana o nā maʻi a me nā maʻi.Hoʻohana nui ke ʻano hoʻokaʻawale kino i ka hopena gravity, ka hopena interception, ka hopena diffusion, a me ka hopena inertia o ka bacteria a me nā ʻāpana maikaʻi.
Hiki i nā koi hoʻolālā o nā masks lapaʻau lapaʻau maʻamau ke kāohi i nā ʻāpana aerosol bacterial ʻoi aku ka nui ma mua o 3 microns i ke anawaena, akā ma muli o ke anawaena pore nui o ka papa kumu o ka mask, ʻaʻole hiki ke hoʻokō pono ʻia ka hoʻokaʻawale kino ʻana o nā ʻāpana liʻiliʻi o ka bacteria a me nā maʻi.Hoʻohana nui kēlā mau masks i nā ʻano electrostatic adsorption.Eia nō naʻe, i ka piʻi ʻana o ka manawa e hoʻohana ai (e like me 1 a 2 mau hola), pulu ka pale ma muli o nā hana a ke kanaka e like me ka hanu ʻana o ka mea hoʻohana, a nāwaliwali kona hiki ke hoʻopili electrostatic, a ʻoi aku ka maikaʻi o ka hopena kaʻawale.No laila, ʻaʻole hiki i nā masks lapaʻau maʻamau ke hoʻokō i ka noho kaʻawale a me ka pale pono no ka wā lōʻihi.
ʻO ka piʻi ʻana o ka noi honua no nā masks ua lilo i kumuhana honua.ʻO nā lole hoʻoheheʻe ʻia i kapa ʻia ʻo ka mask "naʻau" i hoʻomaka mua ʻia ma lalo o $3,000 no ke tona, a i kēia manawa ua piʻi ke kumukūʻai ma mua o $40,000!
I loko o kēia pōʻaiapili, ua lilo nō hoʻi ka hoʻololi ʻana i nā lole meltblown mask i kumuhana wela i kēia mau manawa!ʻAʻohe waiwai o nā mea Meltblown ma ka honua holoʻokoʻa a piha nā hale hana a pau, akā aia kahi mea kānana kiʻekiʻe e pani ana i nā mea meltblown.ʻO ia ka PTFE (polytetrafluoroethylene)!
ʻO ka mea e pono ai ka nānā kiʻekiʻe ʻo ia ka PTFE nano masks i hana ʻia me PTFE (polytetrafluoroethylene) ma ke ʻano he kumu kumu kumu i lilo i kuhikuhi hou no ka hoʻomohala ʻana i nā masks i ka wā e hiki mai ana!
Ua lilo ʻo Nano masks i mea pale pale olakino maikaʻi ma muli o kāna hana kānana maikaʻi loa.E like me nā maka lapaʻau maʻamau, ʻo nā masks nano antibacterial pū kekahi me ka papa waho, ka papa waena, ka ʻāpana o loko, ka makau pepeiao, ka ihu a me nā ʻāpana ʻē aʻe.He mea kūikawā nā Nano masks no ka mea, ua hana ʻia ka papa waena me ka nano-membrane me kahi pore liʻiliʻi (100-200 nanometers), i hana maʻamau ʻia me PTFE.ʻO kakiʻiʻoniʻoni PTFEhana ʻia e ka unidirectional a biaxial hoʻolōʻihi ʻana i ke ʻano microporous pūnaewele like me ka spider web-like ma ka ʻili, a he ʻekolu-dimensional structure me nā loli paʻakikī loa e like me ka pilina pūnaewele, hoʻonohonoho puka, a me ke kuʻekuʻe ʻana o ke kahawai, no laila, he mau hiʻohiʻona kānana maikaʻi loa.
ʻO nā masks Nano i hana ʻia mai nā mea PTFE he mau hiʻohiʻona o ka pono pale pale kiʻekiʻe, ke ola lōʻihi, ka māmā a me ka hanu, a he ʻano hou ia no ka hoʻomohala ʻana i nā masks i ka wā e hiki mai ana.Eia nō naʻe, i kēia manawa, ʻoi aku ke kumukūʻai o ia mau maka PTFE a ʻaʻole hiki ke hoʻololi piha i nā masks kuʻuna.
