ʻO ka ulana ʻole i puhi ʻia i ka heheʻekaʻina hana: hānai polymer - extrusion heheʻe - hoʻokumu fiber - hoʻomaʻalili - i loko o kahi pūnaewele - hoʻoikaika i loko o ka lole.
Ka hoʻomohala ʻana i ka ʻenehana nonwovens melt-Jet -- ʻenehana melt-jet ʻelua-ʻāpana
Mai ke kenekulia 21, ua holomua ka hoʻomohala ʻana o ka ʻenehana melt-jet nonwovens ma ka honua i nā lele a me nā palena.
ʻO ke kumu o ka ʻūpā:
Hiki ke hoʻoluʻolu i nā mea ulana ʻole, hiki ke hana ʻia i nā huahana concentric, eccentric, a me ke ʻano kūikawā. Ma ke ʻano laulā, hana ʻia ke kumu i nā mea makepono, a ʻo ka polymer pipiʻi me nā waiwai kūikawā a i ʻole nā waiwai e pono ai ʻo ia ka papa waho, e like me ke kumu polypropylene a me ka papa waho nylon e hana i ka fiber hygroscopic. ʻO ke kumu he polypropylene, a ʻo ka ʻili waho he polyethylene haʻahaʻa melting point a i ʻole polypropylene i hoʻololi ʻia, polyester i hoʻololi ʻia, a pēlā aku. No ke kaula conductive carbon ʻeleʻele, ua kāʻei ʻia ke kumu conductive i loko.
ʻAno hui:
ʻO ka maʻamau, hana ʻia nā mea ulana ʻole me ka elasticity maikaʻi mai nā polymers ʻelua like ʻole a i ʻole ka polymer like me nā viscosities like ʻole i loko o nā olonā ʻelua-ʻāpana like. Hiki ke hoʻohana ʻia ka hoʻemi wela like ʻole o nā polymers like ʻole e hana i nā olonā i ʻōwili ʻia. No ka laʻana, ua hoʻomohala ka hui 3M i nā mea ulana ʻelua-ʻāpana PET/PP i hoʻoheheʻe ʻia. Ma muli o ka hoʻemi ʻokoʻa, hana nā mea ulana ʻole i ka ʻōwili crimp, kahi e loaʻa ai i nā mea ulana ʻole ka elasticity maikaʻi loa.
ʻAno kikowaena:
ʻO kēia kekahi ʻano polymer ʻē aʻe i loko o ke ʻano lau ʻekolu, ʻano keʻa a me ka hui hope, e like me ka antistatic, conductivity moisture, hiki i ka fiber conductive ke kau ma luna o ka polymer conductive composite, ʻaʻole hiki ke conductive wale nō, conductive, antistatic, a mālama i ka nui o ka polymer conductive.
ʻAno Microdenier:
ʻAno ʻalani o ka petal, hiki ke hoʻohana ʻia ke ʻano ʻāpana ʻāpana ʻāpana, hiki nō hoʻi ke lilo i ʻano ʻāpana mokupuni kai. ʻO ka hoʻohana ʻana i ʻelua mau polymers kūpono ʻole e ʻili ai e hana i kahi pūnaewele fiber superfine, a i ʻole kahi pūnaewele nanofiber, e like me ke ʻano ʻelua-ʻāpana fiber ʻano ʻāpana kimberly-Clark, he pūnaewele fiber super-fine e hoʻohana ana i ka ʻoiaʻiʻo e hiki ke ʻili loa ʻia ka fiber ʻelua-ʻāpana i hana ʻia mai ʻelua mau polymers kūpono ʻole ma lalo o kekona i ka wai wela. ʻO ke ʻano mokupuni kai e hoʻoheheʻe i ke kai e loaʻa ai kahi pūnaewele maikaʻi o nā olonā mokupuni.
Hoʻohuihui:
He pūnaewele ia o nā olonā me nā mea like ʻole, nā kala like ʻole, nā olonā like ʻole, nā ʻano ʻāpana kea like ʻole, a me ke kumu ʻili i hui pū ʻia me nā olonā co-spinning a me nā olonā ʻelua-ʻāpana, i loaʻa i nā olonā nā ʻano waiwai āpau e pono ai. Hiki i kēia ʻano melt-jet two-component fiber nonwovens a i ʻole nā hui fiber nonwovens i hui pū ʻia ke hoʻomaikaʻi hou i ka waiwai kānana o ka kānana media i hoʻohālikelike ʻia me nā huahana fiber melt-jet maʻamau, a hana i ka kānana media i ka waiwai antistatic, conductivity uila, waiwai hygroscopic, waiwai pale i hoʻonui ʻia, a pēlā aku. A i ʻole e hana i ka pilina mesh fiber, fluffy, air permeability hoʻomaikaʻi.
Hiki i ka fiber shotcrete hoʻoheheʻe ʻelua-ʻāpana ke hoʻohui i ka hemahema o ka hana polymer hoʻokahi, e like me ka polypropylene he mea haʻahaʻa ke kumukūʻai, akā no nā mea lapaʻau, ʻaʻole ia e kū i ka hōʻike ʻana o ka radiation, no laila hiki ke polypropylene ma ke ʻano he kumu, ma kona papa waho e koho i ka polymer kū i ka radiation kūpono i kāʻei ʻia ma waho hiki ke hoʻoponopono i ka pilikia o ke kū'ē ʻana o ka radiation. No laila, hiki ke kūʻai ʻole ka huahana a hoʻokō i nā koi hana, e like me nā mea hoʻololi wela a me ka haʻahaʻa no ka ʻōnaehana hanu ma ke kahua lapaʻau, hiki ke hāʻawi i ka wela kūlohelohe kūpono a me ka haʻahaʻa. He māmā kona kaumaha, hoʻolei ʻia a maʻalahi paha e disinfect, cheap, akā hiki ke pāʻani i ke kuleana hou o ka wehe ʻana i nā kānana haumia. Hiki ke haku ʻia me ʻelua mau ʻāpana like ʻelua-ʻāpana melt-spray fiber network.
Hoʻohana ʻia ke ʻano ʻili ʻili ʻelua-ʻāpana, ʻo ke kumu he polypropylene a ʻo ka cortex he nylon. Hiki ke hoʻohālikelike ʻia nā olonā ʻelua-ʻāpana me kahi ʻāpana kūikawā, e like me ke ʻano ʻekolu-lau a i ʻole ke ʻano lau he nui, i hiki ai ke nui aʻe ko lākou ʻili. I kēia manawa, hiki ke hoʻohana ʻia nā polymers e hiki ke hoʻomaikaʻi i ka hana kānana ma ka papa ʻili a i ʻole ka ʻāpana piko o nā olonā. Hiki ke hana ʻia ka ʻupena fiber ʻelua-ʻāpana alkene a i ʻole polyester fusible spray i loko o nā kānana wai a me ke kinoea kolamu. Hiki ke hoʻohana ʻia ka ʻupena fiber ʻelua-ʻāpana hoʻoheheʻe no ka piko kānana cigarette; Hoʻohana ʻia ka hopena omo kumu e hana i ka ʻinika omo kiʻekiʻe. ʻO ke koʻokoʻo omo kumu no ka paʻa ʻana o ka wai a me ka hoʻokomo ʻana, a pēlā aku.
Ka hoʻomohala ʻana i ka ʻenehana nonwovens i puhi ʻia i ka heheʻe -- Nā nanofibers i puhi ʻia i ka heheʻe
No ka hana ʻana i nā nanofibers, ʻoi aku ka liʻiliʻi o nā lua spinneret ma mua o nā mea i loaʻa i nā lako hoʻoheheʻe maʻamau. Hiki i ka NTI ke liʻiliʻi e like me 0.0635 mm (ʻo ia hoʻi 63.5 microns) a i ʻole e like me 0.0025 ft. Hiki ke hoʻohui ʻia nā panela spinneret modular i ka laulā holoʻokoʻa ma mua o 3 m. ʻO ke anawaena o ka fiber spray i milo ʻia ma kahi o 500 nanometers. Hiki i nā fibers hoʻokahi maikaʻi loa ke piʻi i 200 nanometers ke anawaena.
ʻOiai he mau lua liʻiliʻi orifical nā lako hana hoʻoheheʻe a me ka pīpī ʻana no ka milo ʻana i nā nanofibers, inā ʻaʻohe hana e lawe ʻia, e emi nui ka hopena. No laila, hoʻohana ʻo NTI i ke ʻano o ka hoʻonui ʻana i ka helu o nā lua orifical, a he 3 a ʻoi aku paha nā lālani o nā lua orifical o kēlā me kēia pā spinneret. Ma ka hoʻohui ʻana i kahi helu o nā ʻāpana unit (ma muli o ka laulā), hiki ke hoʻonui nui ʻia ka hua i ka wā o ka milo ʻana. ʻO ke kūlana maoli, i ka wā e hoʻohana ʻia ai nā lua 63.5 micron, ʻo ka helu o nā lua i hoʻokahi lālani o nā spinnerets i kēlā me kēia mika he 2880. Inā hoʻohana ʻia ʻekolu lālani, hiki i ka helu o nā lua i hoʻokahi lālani o nā spinnerets i kēlā me kēia mika ke hiki i 8640, i hiki ai ke hoʻohālikelike ʻia ka hopena me ka milo ʻana i ke kaula shotcrete hoʻoheheʻe maʻamau.
Ma muli o ke kumukūʻai o nā spinnerets lahilahi me nā lua mānoanoa kiʻekiʻe a maʻalahi hoʻi i ka haki (ka haki ʻana ma lalo o ke kaomi kiʻekiʻe), ua hoʻomohala nā ʻoihana i nā ʻano hana hoʻopaʻa hou e hoʻoikaika i ka paʻa o nā spinnerets a pale i ka liki ʻana ma lalo o ke kaomi kiʻekiʻe.
Nanometer i hoʻopili ʻia - hiki ke hoʻohana ʻia ka fiber i pīpī ʻia ma ke ʻano he kānana waena, hiki ke hoʻomaikaʻi nui i ka pono o ka kānana. Aia kekahi ʻikepili e hōʻike ana no ka mea ʻoi aku ka lahilahi o ka fiber i loko o nā nonwovens nanometer melt-jet, hiki ke hui pū ʻia ka lole melt-jet me ka lole spunbonded me ke kaumaha gram māmā, hiki ke kū i ke kaomi poʻo wai like, a hiki i nā huahana SMS i hana ʻia mai ia mea ke hōʻemi i ka hapa o ka fiber melt-jet.
Helole ulana ʻole i hoʻoheheʻe ʻia no ka pale makahale hana, e ʻoluʻolu e kūkākūkā me mākou ~
