Kaʻina a me nā hiʻohiʻona o ka lole i ulana ʻole ʻia

ʻO ke kaʻina hana o ka lole i ulana ʻole ʻia

ʻO ke kaʻina hana o ka lole hoʻoheheʻe ʻole i ulana ʻia: hānai polymer - hoʻoheheʻe hoʻoheheʻe - hoʻokumu ʻana i ka fiber - hoʻoluʻu fiber - hoʻokumu pūnaewele - hoʻoikaika i ka lole.

ʻElua ʻenehana hoʻoheheʻe ʻia

Mai ka hoʻomaka ʻana o ke kenekulia 21, ʻo ka hoʻomohala ʻana i ka ʻenehana melt blown nonwoven ua holomua wikiwiki i ka honua.

Ua hoʻomohala maikaʻi nā hui ʻo Hills a me Nordson ma ʻAmelika Hui Pū ʻIa i ʻelua mau mea i hoʻoheheʻe ʻia melt blown ʻenehana ma mua, me ka ʻili ʻili, parallel, triangular a me nā ʻano ʻē aʻe. ʻO ka maikaʻi o ka fiber kahi kokoke i 2 µ, a ʻo ka helu o nā lua i ka mea hoʻoheheʻe filament hiki ke hiki i 100 mau puka i kēlā me kēia ʻīniha, me ka helu extrusion o 0.5g / min no ka lua.

ʻAno kumu ʻili:

Hiki iā ia ke hana i nā lole i ulana ʻole ʻia me ka palupalu a hiki ke hana ʻia i nā huahana concentric, eccentric, a me nā mea like ʻole. ʻO ka mea maʻamau, hoʻohana ʻia nā mea maʻalahi ma ke ʻano he kumu, ʻoiai nā polymers pipiʻi me nā waiwai kūikawā a i ʻole nā ​​​​mea pono e hoʻohana ʻia e like me ka papa waho, e like me ka polypropylene no ke kumu a me ka nylon no ka papa waho, e hana ana i nā fibers hygroscopic; Hana ʻia ke kumu me ka polypropylene, a ʻo ka ʻaoʻao o waho i hana ʻia me ka polyethylene melting point haʻahaʻa a i ʻole polypropylene i hoʻololi ʻia, polyester i hoʻololi ʻia, etc. hiki ke hoʻohana ʻia no ka hoʻopaʻa ʻana. No nā fiber conductive kalapona ʻeleʻele, ua wahī ʻia ke kumu conductive i loko.

ʻAno like:

Hiki iā ia ke hana i nā lole i ulana ʻole ʻia he elasticity maikaʻi, hana mau ʻia me nā polymers ʻokoʻa ʻelua a i ʻole ka polymer like me nā viscosities like ʻole e hana i nā fibers ʻelua ʻāpana. Ma ka hoʻohana ʻana i nā waiwai hoʻemi wela o nā polymers ʻokoʻa, hiki ke hana ʻia nā fiber curled spiral. No ka laʻana, ua hoʻomohala ʻo 3M Company i kahi lole i ulana ʻole ʻia i hana ʻia me ka hoʻoheheʻe ʻia ʻana o ka PET/PP ʻelua mau mea kikoʻī, ka mea, ma muli o ka hoʻohaʻahaʻa ʻokoʻa, hana i kahi curl spiral a hāʻawi i ka lole i ulana ʻole ʻia ka elasticity maikaʻi loa.

ʻAno hoʻopau:

ʻO kēia kekahi ʻano o ka polymer composite i hoʻohana ʻia i nā ʻano lau ʻekolu, ke keʻa, a me nā ʻano hope. I ka hana ana i ka anti-static, moisture conductive, a me ka conductive fibers, conductive polymers hiki ke hoʻohui ʻia ma luna, ʻaʻole hiki ke alakaʻi wale i ka makū, akā alakaʻi pū kekahi i ka uila, anti-static, a mālama i ka nui o ka polymer conductive i hoʻohana ʻia.

ʻAno Micro Dan:

Hiki ke hoʻohana ʻia nā ʻāpana ʻili i ke ʻano o ka petal alani, a i ʻole nā ​​ʻāpana ʻano mokupuni. Ke hoʻohana nei i ʻelua polymers kūpono ʻole e ʻili a hana i nā pūnaewele fiber ultrafine, ʻo ia hoʻi nā pūnaewele nanofiber. No ka laʻana, ua hoʻomohala ʻo Kimberly Clark i ka peeling fiber two-component fiber, e hoʻohana ana i nā hiʻohiʻona o nā ʻāpana ʻelua i hana ʻia mai ʻelua polymers like ʻole i hiki ke ʻoki loa ʻia i ka liʻiliʻi ma mua o hoʻokahi kekona i ka wai wela e hana i nā pūnaewele fiber ultrafine. No ke ʻano mokupuni, pono e hoʻoheheʻe ʻia ke kai no ka loaʻa ʻana o kahi ʻupena fiber mokupuni maikaʻi.

ʻAno huila:

He punawelewele pulupulu i hana ʻia ma ka hui ʻana i nā mea like ʻole, nā waihoʻoluʻu, nā pulupulu, nā ʻano ʻāpana keʻa, a me nā fibers e like me ka ʻili o ka ʻili, me ka co spun a me nā ʻāpana ʻelua, e hāʻawi i nā fibers i nā waiwai i makemake ʻia. Ke hoʻohālikelike ʻia me nā huahana hoʻoheheʻe maʻamau, hiki i kēia ʻano o ka hoʻoheheʻe ʻana i ʻelua-component fiber nonwoven fabric a i ʻole i hui pū ʻia ka fiber nonwoven fabric hiki ke hoʻomaikaʻi hou i ka hana kānana o ke kānana kānana, a hana i ka mea kānana he anti-static, conductive, moisture absorbing, a hoʻonui i nā waiwai pale; A i ʻole e hoʻomaikaʻi i ka adhesion, fluffiness, a me ka hanu o ka pūnaewele fiber.

Hiki i ʻelua ʻāpana meltblown fiber ke hoʻohui i nā hemahema o nā waiwai polymer hoʻokahi. No ka laʻana, he mea maʻalahi ka polypropylene, akā ke hoʻohana ʻia i nā lāʻau lapaʻau a me nā mea olakino, ʻaʻole ia e pale i ka hoʻolaha ʻana i ka radiation. No laila, hiki ke hoʻohana ʻia ka polypropylene ma ke ʻano he kumu, a hiki ke koho ʻia kahi polymer pale radiation kūpono ma ka ʻaoʻao o waho e kāʻei a puni, pēlā e hoʻonā ai i ka pilikia o ka pale ʻana i ka radiation. Hiki i kēia ke hana i ke kumukūʻai o ka huahana i ka wā e hoʻokō ai i nā koi hana, e like me ka hoʻololi ʻana i ka wela a me ka haʻahaʻa i hoʻohana ʻia i loko o ka ʻōnaehana hanu i ka lāʻau lapaʻau, hiki ke hāʻawi i ka wela kūlohelohe kūpono a me ka haʻahaʻa. He māmā, hoʻopau a maʻalahi hoʻi e disinfect, maʻalahi, a hiki ke lilo i kānana hou no ka wehe ʻana i nā mea haumia. Hiki ke haku ʻia i ʻelua mau mea hoʻoheheʻe i hoʻoheheʻe ʻia. ʻO ka hoʻohana ʻana i ke ʻano o ka ʻili kumu ʻelua ʻāpana fiber, hana ʻia ke kumu me ka polypropylene a ʻo ka ʻili o ka ʻili i hana ʻia me ka nylon. Hiki i nā ʻāpana ʻelua ke hoʻohana i nā ʻāpana ʻokoʻa like ʻole, e like me trilobites a me multilobes, e hoʻonui i ko lākou ʻili. I ka manawa like, hiki ke hoʻohana ʻia nā polymers i hiki ke hoʻomaikaʻi i ka hana kānana ma luna o ko lākou ʻili a i ʻole ka piko o ka lau. Hiki ke hana ʻia ke ʻano hoʻoheheʻe ʻia ʻelua o ka ʻolefin a i ʻole polyester i loko o ka wai cylindrical a me nā kānana kinoea. Hiki ke hoʻohana pū ʻia ka mesh fiber ʻelua i hoʻoheheʻe ʻia no nā ʻōlelo aʻoaʻo kānana cigarette; Ka hoʻohana ʻana i ka hopena hoʻoheheʻe koʻikoʻi no ka hana ʻana i nā ʻīnika kiʻekiʻe kiʻekiʻe; ʻO nā lāʻau hoʻoheheʻe kumu no ka hoʻopaʻa ʻana i ka wai a me ka infusion.

Ka hoʻomohala ʻana i ka ʻenehana hoʻoheheʻe ʻole i ulana ʻia - nā nanofibers i hoʻoheheʻe ʻia

I ka wā ma mua, ua hoʻokumu ʻia ka hoʻomohala ʻana o nā fibers meltblown i ka ʻenehana patented a Exxon, akā i nā makahiki i hala iho nei, ua haki kekahi mau hui honua i ka ʻenehana a Exxon e hoʻomohala i nā finer nanoscale.

Ua hana ʻo Hills Company i kahi noiʻi nui e pili ana i nā fibers nano meltblown a ua ʻōlelo ʻia ua hiki i ka pae o ka ʻenehana. Ua hoʻomohala nā hui ʻē aʻe e like me Non woven Technologies (NTI) i nā kaʻina hana a me nā ʻenehana no ka hana ʻana i nā fibers nano meltblown a ua loaʻa iā lākou nā patent.

I mea e wili ai i nā nanofibers, ʻoi aku ka maikaʻi o nā puka nozzle ma mua o nā mea ma nā mea hoʻoheheʻe maʻamau. Hiki i ka NTI ke hoʻohana i nā nozzles liʻiliʻi e like me ka 0.0635 millimeters (63.5 microns) a i ʻole 0.0025 iniha, a hiki ke hoʻohui ʻia ke ʻano modular o ka spinneret e hana i ka laulā holoʻokoʻa ma mua o 3 mika. ʻO ke anawaena o nā pulu i hoʻoheheʻe ʻia i wili ʻia ma kēia ala ma kahi o 500 nanometers. Hiki ke hiki i ka 200 nanometers ke anawaena fiber hoʻokahi.

ʻO nā mea hoʻoheheʻe i puhi ʻia no ka wili nanofibers he mau lua liʻiliʻi liʻiliʻi, a inā ʻaʻohe ana i lawe ʻia, e hoʻemi nui ʻia ka hua. No laila, ua hoʻonui ʻo NTI i ka helu o nā lua ehu, me kēlā me kēia pā pāpaʻi he 3 a ʻoi aʻe paha nā lālani o nā lua. ʻO ka hui pū ʻana i nā ʻāpana he nui (e pili ana i ka laula) hiki ke hoʻonui nui i ka hua i ka wā wili. ʻO ke kūlana maoli ka wā e hoʻohana ai i nā lua micron 63.5, ʻo ka helu o nā puka ma ka mika o ka lālani spinneret hoʻokahi he 2880. Inā hoʻohana ʻia nā lālani ʻekolu, hiki i ka helu o nā puka hoʻokahi mika o ka spinneret ke hiki i 8640, ʻo ia ka mea e like me ka hana ʻana o nā fibers hehee maʻamau.

Ma muli o ke kumukūʻai kiʻekiʻe a me ka maʻalahi o ka haki ʻana (ka haki ʻana ma lalo o ke kaomi kiʻekiʻe) o nā spinnerets lahilahi me nā lua kiʻekiʻe kiʻekiʻe, ua hoʻomohala nā ʻoihana like ʻole i nā ʻenehana paʻa hou e hoʻonui ai i ka lōʻihi o nā spinnerets a pale i ka leakage ma lalo o ke kaomi kiʻekiʻe.

I kēia manawa, hiki ke hoʻohana ʻia nā fibers nano meltblown e like me ka media filtration, hiki ke hoʻomaikaʻi nui i ka pono kānana. Aia kekahi ʻikepili e hōʻike ana ma muli o ka ʻoi aku o ka ʻoi aku ka maikaʻi o ka nanoscale meltblown nonwoven fabrics, ʻoi aku ka māmā a me ke kaumaha o nā lole meltblown hiki ke hoʻohana ʻia me ka hui pū ʻana me ka spunbond composites, hiki ke kūpaʻa i ke poʻo wai like. Hiki i nā huahana SMS i hana ʻia mai iā lākou ke hōʻemi i ka nui o nā meltblown fibers.

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.
