Hoʻopili i ke kumu o kalole i puhi ʻia i ka heheʻeHana ʻia ka mea kānana me ka polypropylene superfine fiber me ka hoʻolaha maʻamau, ʻo ke ʻano, laumania, palupalu a keʻokeʻo ka fiber fineness o 0.5 a 1.0 mu m, ʻo ka hoʻolaha maʻamau o ka fiber e hāʻawi i nā manawa hou aku no ka hoʻopili wela ma waena o ka fiber a pēlā e hana ai i ka mea kānana kinoea heheʻe-puhi he ʻili kikoʻī nui aʻe, porosity kiʻekiʻe (75%) a ʻoi aku paha. Ma o ka pono kānana stationer kiʻekiʻe, loaʻa i ka huahana nā ʻano o ke kū'ē haʻahaʻa, ka pono kiʻekiʻe a me ka mana lepo kiʻekiʻe.
ʻO ke kikowaena o kahi mask
ʻO ka lole ulana ʻole i hoʻoheheʻe ʻia ma ke ʻano he ʻano hou o ka mea kānana kiʻekiʻe kiʻekiʻe ʻo ia nā masks "puʻuwai", i hoʻohālikelike ʻia me ka mea kānana kuʻuna, ka kānana ea a me ka hoʻomaʻemaʻe pono i ka hoʻomaikaʻi ʻana o hoʻokahi haneli mau manawa, ʻo ia ka mea kūpono loa no nā mea palekana olakino olaola (hiki ke hoʻohana ʻia ke kalapona i hoʻāla ʻia a me nā mea like no nā kemika pale, kūʻē i nā bacteria a me nā virus me ka ʻole o ka hana hoʻomaʻemaʻe kānana). ʻO kona hānau ʻana i ka pō hoʻokahi i hoʻohana ʻole ʻia e ka ʻoihana lapaʻau i hoʻokahi haneli mau makahiki i hoʻopau loa ʻia ka mask gauze. Hoʻokaʻawale pinepine ʻia ka pale lapaʻau i ʻekolu mau pae e like me ke kiʻekiʻe o nā koi pale. ʻO nā "masks ʻokiʻoki" polū māmā a mākou e ʻaʻahu pinepine ai hiki ke hoʻohana ʻia no ka pale mua, ʻo ia hoʻi e kūʻē i ka hoʻoili ʻino ʻana o nā droplets e loaʻa ana nā pathogens i ke ola o kēlā me kēia lā a me ka hana ʻana. ʻO ke ana nui e hoʻomaikaʻi i ka hiki ke pale, ʻo ia ka hoʻohui ʻana i kahi papa kānana i hana ʻia me ka lole ulana ʻole i hoʻoheheʻe ʻia i waenakonu o ka mask.
ʻO ka papa pale ma waenakonu o ka pale maka (papa M no ka pōkole) he lole ulana ʻole i hoʻoheheʻe ʻia e ka polypropylene, a ʻo nā ʻaoʻao mua a me hope o ka pale maka he mau papa i hoʻopili ʻia (papa S no ka pōkole). Ma muli o ka pae o ka pale e pono ai, hiki ke kau ʻia hoʻokahi a ʻoi aku mau papa i loko o ka papa M. Inā he pale maka pae 1, e hoʻohana i kahi papa M. No kahi respirator pae 3 e like me ka N95, pono paha ka papa M i ʻekolu mau papa o ka lole ulana ʻole i hoʻoheheʻe ʻia a ʻoi aku paha. ʻOiaʻiʻo, ʻo ka nui o nā papa o ka papa M, ʻoi aku ka ʻino o ka permeability ea o ka pale maka, e ʻokoʻa nā huahana kikoʻī.
Inā mākou e haehae i kahi pale maka, e ʻike mākou i nā papa ʻekolu ma luna, ʻo ia hoʻi ka papa hygroscopic, ka papa kānana koʻikoʻi, a me ka papa pale wai.
ʻO ka lole pīpī hoʻoheheʻe, aia ma waenakonu o ka papa kānana mask, hiki ke kānana i nā bacteria, pale i ka laha ʻana o nā germs. ʻO ka lole pīpī hoʻoheheʻe, ka lole pīpī hoʻoheheʻe nui i ka polypropylene ma ke ʻano he mea maka nui, hiki ke piʻi ke anawaena o ka fiber i 1 ~ 5 micron. ʻO kēia mau fibers ultrafine me ke ʻano capillarity kū hoʻokahi e hoʻonui i ka helu a me ka ʻili o nā fibers i kēlā me kēia ʻāpana, i loaʻa i ka lole melt-jet nā kānana maikaʻi, pale, insulation a me nā waiwai omo aila. Hiki ke hoʻohana ʻia i ka lewa, nā mea kānana wai, nā mea hoʻokaʻawale, nā mea omo, nā mea mask, nā mea insulation thermal, nā mea omo aila a me ka lole holoi a me nā kahua ʻē aʻe.
ʻO ka hoʻopili ʻana a me ka adsorption
ʻO ka lole i puhi ʻia i ka heheʻe he ʻano polypropylene me ka helu hoʻoheheʻe kiʻekiʻe, i hana ʻia me nā olonā criss-cross he nui i laminated ma ke kuhikuhi kaulele. ʻO ke anawaena o nā olonā mai 0.5 a 10 microns, a ʻo ke anawaena o nā olonā ma kahi o hoʻokahi kanakolu o ka lauoho.
E like me ka mea i ʻike ʻia mai ke kiʻi, nui nō nā hakahaka i loko o ka pale maka ma lalo o ka microscope electron. No laila pehea lā e hiki ai iā kākou ke ālai i ka maʻi?
Nā pale makapale aku i nā virus ma ka hana ʻana i ʻelua mau mea: ka pahele ʻana a me ka pahele ʻana
Ka Hoʻopaʻa ʻana:
Hilinaʻi ka mea kānana i nā kaʻina hana lole a i ʻole nā mea i ulana ʻole ʻia e hoʻokō i ka nui o nā olonā i loko o ka hakahaka a hana i kahi pūnaewele o nā pores, no laila e hana ana i kahi hopena "pale" i ka ea e kahe ana. ʻO nā ʻāpana nui i ka lewa e "hoʻopaʻa ʻia" e ke kuʻi ʻana me nā olonā a i ʻole e ka ʻūpā fiber e pale ana ma ka ʻaoʻao o ka mea kānana. No nā ʻāpana ʻole olaola i ka lewa (e like me ka lepo, PM2.5, a pēlā aku), ʻo ka pono o ka hoʻomaʻemaʻe ʻana o nā masks e hilinaʻi nui ʻia ma ka hiki ke hoʻopaʻa hoʻokahi o nā mea kānana.
Hoʻopili ʻana:
No nā pale pale olaola, ma muli o ka liʻiliʻi o ke kino o nā pathogens e like me nā virus, he paʻakikī ke hoʻomaʻemaʻe i ka hapa nui o nā mea ʻino ma o ka interception o nā hakahaka fiber mask. No laila, ua lilo ka adsorption electrostatic i mea nui o ka hana pale mask. He nāwaliwali loa nā fiber kūlohelohe kuʻuna i ka hana ʻana a me ka lawe ʻana i ka uila static, no laila he liʻiliʻi ka hopena adsorption o nā masks gauze. A ʻo ka fiber melt jet non-polar polymer non-polar he mea maikaʻi loa ia no ka hana electrostatic a me ka paʻa ʻana (i kēia kiko, hiki iā ʻoe ke hoʻohālikelike i ka manaʻo o ke komo ʻana i nā lole pulupulu maʻemaʻe a me nā lole fiber kemika), e hana ana iā ia he "maoli" he hana adsorption maikaʻi loa. Ua hana nui nā mea noiʻi i ke ʻano o ka hana ʻana a me ka mālama ʻana i ka pono electrostatic o nā mea kānana. I ka hana mask, hoʻohana ʻia nā ʻano mechanical a uila paha e hoʻonui i ka uku electrostatic i loko o nā mea pīpī hoʻoheheʻe ʻia.
Ma muli o ke ʻano kū hoʻokahi o ka adsorption electrostatic, hiki i ka ʻenehana hoʻoheheʻe hoʻoheheʻe ke hana i nā fibers kemika me ke anawaena hoʻokahi kauoha o ka nui i ʻoi aku ka liʻiliʻi ma mua o nā fibers kūlohelohe, kahi mea kūpono hoʻi i ka hanauna o ka adsorption kemika. ʻO ka lole ulana ʻole i hoʻoheheʻe ʻia e ka polypropylene melt-sprayed ʻo ia ke koho mua no nā mea pale pale lapaʻau.
