He aha ka lole i ulana ʻole ʻia

He aha ka melt blown non-woven fabric

ʻO ka lole hoʻoheheʻe ʻole i ulana ʻia he ʻano lole lole hou i hana ʻia mai nā mea polymer kiʻekiʻe ma o nā kaʻina hana e like me ka hoʻomākaukau ʻana i nā mea maka, ka hoʻoheheʻe wela kiʻekiʻe, ka hoʻoheheʻe ʻana, ka hoʻoluʻu a me ka paʻa. Ke hoʻohālikelike ʻia me nā lole i ulana ʻole ʻia, hoʻoheheʻe ʻia nā lole ʻaʻole i ulana ʻia he ʻoi aku ka ʻoi aku ka maikaʻi a ʻoi aku ka maikaʻi o ka hoʻolālā ʻana o ka fiber, a me kekahi breathability a me ka pale wai, e hana ana iā lākou i alakaʻi hoʻomohala koʻikoʻi i ke kahua o nā mea textile.

ʻO nā hiʻohiʻona o ka melt blown non-woven fabric

1. ʻO ka hana kānana maikaʻi, hiki ke pale pono i ka hoʻolaha ʻana o nā mea ʻino e like me nā ʻāpana, bacteria, virus, etc.

2. Malū a ʻoluʻolu, me ka hanu maikaʻi, ʻoluʻolu e ʻaʻahu, ʻaʻohe hopena maʻi;

3. E hoʻohana i ka pale, ka wai a me kaʻaila, me ka lōʻihi o ka lawelaweʻana a me ka maikaʻi loa;

4. Maʻalahi ka hana, hiki ke ʻoki, humuhumu, kaomi wela, laminating a me nā hana ʻē aʻe e like me nā pono like ʻole.

ʻO ka hoʻohana ʻana i ka lole i ulana ʻole ʻia

ʻO ka lole i ulana ʻole ʻia i hoʻoheheʻe ʻia he ākea ka nui o nā manaʻo noi, a ua ʻimi ʻia ma nā kula e like me ke olakino, ka maʻemaʻe, a me nā lako hale. ʻO nā wahi noi nui e like me kēia:

1. Lapaʻau a me ke Ola: Hoʻohana nui ʻia ka lole hoʻoheheʻe ʻole i ulana ʻia i ka hana ʻana i nā mea pale e like me nā masks, nā lole ʻokiʻoki, a me nā lole kaʻawale, hiki ke hoʻokaʻawale maikaʻi i ka bacteria a me nā maʻi, e hōʻoia ana i ka palekana o nā limahana lapaʻau a me nā maʻi.

2. Nā lako hale: Hoʻohana ʻia ka lole i hoʻoheheʻe ʻia e hoʻoheheʻe ʻia e hana i nā mea e pono ai i kēlā me kēia lā e like me ka holoi ʻana i ka wai, nā mea hoʻomaʻemaʻe maka, a me nā lole holoi me ka wai maikaʻi o ka wai, ke kūpaʻa wai, a ʻaʻole maʻalahi e hoʻokahe i ka lauoho, e hoʻomaikaʻi i ka ʻike mea hoʻohana.

3. Mea kānana: Hiki ke hana ʻia ka lole hoʻoheheʻe ʻole i ulana ʻia i mea kānana no ka ea, ka wai, a me ka ʻaila, hiki ke hoʻoneʻe pono i nā ʻāpana i ka lewa a hoʻemi i nā hoʻokuʻu pollutant. Hiki ke hoʻohana ʻia i nā māla e like me ka kānana mīkini a me ka kānana wai inu.

ʻO ka lole i ulana ʻole ʻia i hoʻoheheʻe ʻia he mea hoʻokaʻawale maikaʻi

ʻO ka lole hoʻoheheʻe ʻole i ulana ʻia he wahi ākea nui a me nā puka liʻiliʻi (pore nui ≤ 20) μm) Porosity kiʻekiʻe (≥ 75%) a me nā ʻano ʻē aʻe. Inā ka awelika anawaena he 3 μ Ka kikoʻī ili wahi o ka hehee puhi nonwoven lole pulupulu, e like me ka awelika puluniu anana o 0.0638 dtex (me ka puluniu nui o 0.058 denier), hiki i 14617 cm2 / g, oiai ka awelika anawaena he 15.3 μ Ka kiko'ī ili wahi o spunbond, nonwovenvalents density. ʻO 1.65 dtex (me ka nui o ka fiber o 1.5), he 2883 cm2/g wale nō.

Ma muli o ka liʻiliʻi liʻiliʻi o ka thermal conductivity o ka ea i hoʻohālikelike ʻia me nā fibers maʻamau, ʻo ka ea i loko o nā pores o ka lole i hoʻoheheʻe ʻole ʻia i hoʻoheheʻe ʻia e hōʻemi i kona conductivity thermal. ʻO ka lilo o ka wela i hoʻoili ʻia ma o ka fiber material o ka mea hoʻoheheʻe ʻia i ka lole nonwoven he mea liʻiliʻi loa, a ʻo ka ea ea paʻa ma ka ʻili o nā fibers ultrafine he nui e pale i ka hoʻololi ʻana o ka wela ma muli o ke kahe ʻana o ka ea, e loaʻa ai ka insulation maikaʻi a me nā hopena hoʻomehana.

ʻO ka polypropylene (PP) fiber kahi ʻano o nā mea fiber i loaʻa me ka haʻahaʻa haʻahaʻa haʻahaʻa. ʻO ka floc hoʻoheheʻe wela i hoʻoheheʻe ʻia i hana ʻia me ka fiber PP ma hope o ka hoʻomaʻamaʻa kūikawā he 1.5 mau manawa i ka hoʻohaʻahaʻa ʻana i lalo a he 15 mau manawa o ka pulupulu wela wela maʻamau. ʻOi aku ka maikaʻi no ka hana ʻana i nā lole ski, nā lole piʻi mauna, nā moena, nā ʻeke moe, nā lole wela wela, nā mīkina lima, nā kāmaʻa, a me nā mea ʻē aʻe.

Pehea e hoʻomaikaʻi ai i ka pono kānana o ka lole i ulana ʻole ʻia

ʻO ka lole i ulana ʻole ʻia i hoʻoheheʻe ʻia, ʻo ia ke kumu kumu o nā masks lapaʻau, ʻo kona pono kānana e pili pono i ka hopena pale o ka mask. Nui nā mea e pili ana i ka hana kānana ʻana o nā lole i ulana ʻole ʻia, e like me ka fiber linear density, fiber mesh structure, thickness, and density. Ma keʻano he mea kānana ea no nā masks, inā paʻa loa ka mea, liʻiliʻi nā pores, a he kiʻekiʻe loa ke kū'ēʻana o ka hanu,ʻaʻole hiki i ka mea hoʻohana ke hoʻoulu i ka ea me ka maʻalahi, a nalowale ka waiwai no ka hoʻohana. Pono kēia i nā mea kānana ʻaʻole e hoʻomaikaʻi wale i kā lākou kānana ponoʻī, akā e hōʻemi hoʻi i ko lākou kūʻē ʻana i ka hanu, ʻo ia ke kūʻē ʻana ma waena o ka hanu hanu a me ka pono kānana. ʻO ke kaʻina hana electret electrostatic kahi ala maikaʻi e hoʻoponopono ai i ke kū'ē ma waena o ke kū'ē hanu a me ka pono kānana.

Keakea mīkini

ʻO ka awelika fiber anawaena o ka polypropylene melt blown fabric he 2-5 μm. ʻOi aku ka nui o ka ʻāpana ma mua o 5 i ka lewa μ Hiki ke ālai ʻia nā kulu o ka m e ka lole hehee; Ke emi iho ke anawaena o ka lepo maikaʻi ma mua o 3 μ Ma ka m, ma muli o ka hoʻonohonoho maʻamau o nā fibers a me nā interlayers i ka lole i hoʻoheheʻe ʻia, ua hoʻokumu ʻia kahi papa kānana fiber me nā kahawai curved he nui. Ke hele ʻia nā ʻāpana ma nā ʻano ʻano o nā ala curved a i ʻole nā ​​​​alanui, hoʻopili ʻia ka lepo maikaʻi ma luna o ka ʻili o nā fiber e nā kānana mechanical van der Waals; Ke nui ka nui o ka nui a me ka wikiwiki o ka ea, hoʻokokoke ka ea i ka mea kānana a kahe a puni ma muli o ke keʻakeʻa ʻana, ʻoiai ka wehe ʻana o nā ʻāpana mai ke kahawai ma muli o ka inertia a kū pololei me nā fibers e hopu ʻia; Ke liʻiliʻi ka nui o ka ʻāpana a me ka haʻahaʻa o ke kahe ʻana, hoʻopuehu nā ʻāpana ma muli o ka neʻe ʻana o Brownian a hui pū me nā fibers e hopu ʻia.

Electrostatic adsorption

Electrostatic adsorption e pili ana i ka hopu ʻana i nā ʻāpana e ka ikaika Coulomb o ka fiber i hoʻopaʻa ʻia (electret) i ka wā e hoʻopiʻi ʻia ai nā fibers o ka mea kānana. Ke hele ka lepo, bacteria, virus, a me nā mea ʻē aʻe i loko o ka mea kānana, ʻaʻole wale ka ikaika electrostatic e huki i nā ʻāpana i hoʻopaʻa ʻia, akā hopu pū kekahi i nā ʻāpana kūʻokoʻa polarized i hoʻokomo ʻia ma o ka hopena induction electrostatic. Ke piʻi aʻe ka mana electrostatic, ʻoi aku ka ikaika o ka hopena adsorption electrostatic.
