Spunlace nonwoven o ka fiber pre-oxygenated
Mākeke māhele:
Nā hiʻohiʻona o Pre-Oxygenated Fiber:
· ʻO ka pau ʻana o ka lapalapa ahi: ʻo ka palena o ka oxygen index (LOI) maʻamau maʻamau > 40 (ʻo ka hapa o ka oxygen i ka lewa ma kahi o 21%), ʻoi aku ma mua o nā fibers pale ahi maʻamau (e like me ka polyester pale ahi me ka LOI ma kahi o 28-32). ʻAʻole ia e hoʻoheheʻe a kulu paha ke ʻike ʻia i ke ahi, e kinai iā ia iho ma hope o ka wehe ʻana i ke kumu ahi, a hoʻokuʻu i ka uahi liʻiliʻi a ʻaʻohe kinoea ʻona i ka wā e puhi ai.
· Kūlana Kūlana Kiʻekiʻe: Hiki i ka mahana hoʻohana lōʻihi ke hiki i 200-250 ℃, a hiki i ka wā pōkole ke kū i ka 300-400 ℃ kiʻekiʻe kiʻekiʻe (e pili ana i nā mea maka a me ka pae pre-oxidation). Hoʻomau mau ia i ka pono o ke kūkulu ʻana a me nā waiwai mechanical i nā wahi wela kiʻekiʻe.
· Ke Kū'ē Kemika: Loaʻa iā ia ke kū'ē i nāʻakika, alkalis, a me nā mea hoʻoheheʻe organik, aʻaʻole hiki ke hoʻopauʻia e nā mea kemika, kūpono no ka hoʻohanaʻana i nā wahi paʻakikī.
· Kekahi Mechanical Properties: Loaʻa iā ia ka ikaika tensile a me ka paʻakikī, a hiki ke hana ʻia i mau mea me ka hale paʻa ma o nā ʻenehana hana lole nonwoven (e like me ke kuʻi kui, spunlace).
II. ʻenehana hana o nā lole i ulana ʻole ʻia ma mua o ka oxygen
Pono e hana ʻia ka fiber pre-oxygenated i mau mea like me ka pepa ma o nā ʻenehana hana lole nonwoven. Aia nā kaʻina hana maʻamau:
· ʻO ke ʻano o ke kuʻi ʻana i ka nila: Ma ke ʻoki pinepine ʻana i ka ʻupena fiber me nā nila o ka mīkini kuʻi kui, hoʻopaʻa a hoʻoikaika kekahi i kekahi, e hana ana i kahi lole nonwoven me kahi mānoanoa a me ka ikaika. He kūpono kēia kaʻina hana no ka hana ʻana i nā lole fiberless pre-oxygenated kiʻekiʻe kiʻekiʻe, hiki ke hoʻohana ʻia i nā hiʻohiʻona e koi ana i ke kākoʻo kūkulu (e like me nā panela ahi, nā mea kānana wela kiʻekiʻe).
· Spunlaced Method: Ke hoʻohana nei i nā ʻauwaʻa wai kiʻekiʻe e hoʻopā ai i ka fiber mesh, hui pū nā fibers a hoʻopaʻa pū. ʻO ka lole spunlaced pre-oxygenated he ʻoi aku ka palupalu a me ka hanu maikaʻi ʻana, a kūpono ia no ka hoʻohana ʻana i ka ʻāpana o loko o nā lole pale, nā pale ahi hiki ke hoʻololi ʻia, etc.
· Hoʻopaʻa Thermal / Chemical Bonding: Ma ka hoʻohana ʻana i nā fibers hoʻoheheʻe haʻahaʻa (e like me ka flame-retardant polyester) a i ʻole nā mea hoʻopili e kōkua i ka hoʻoikaika ʻana, hiki ke hoʻemi ʻia ka ʻoʻoleʻa o ka lole fiberless pre-oxygenated maʻemaʻe, a hiki ke hoʻomaikaʻi ʻia ka hana hana (akā, e hoʻomanaʻo ʻo ke kūpaʻa wela o ka mea hoʻopili pono e hoʻohālikelike i ke ʻano o ka hoʻohana mua ʻana o ka lole).
I ka hana maoli, ua hui pinepine ʻia nā fibers pre-oxidized me nā fibers ʻē aʻe (e like me ka aramid, flame-retardant viscose, glass fiber) e kaulike i ke kumukūʻai, manaʻo a me ka hana (no ka laʻana, paʻakikī ka lole maʻemaʻe pre-oxidized non-woven, akā ʻo ka hoʻohui ʻana i ka 10-30% flame-retardant viscose hiki ke hoʻomaikaʻi i kona palupalu).
III. Nā hiʻohiʻona hoʻohana kikoʻī o ka lole non-woven pre-oxidized fiber
Ma muli o kāna mau waiwai pale ahi a me ka wela kiʻekiʻe, he mea nui ka lole pre-oxidized fiber non-woven i nā wahi he nui:
1. Ke ahi a me ka palekana pilikino
· ʻO ke ahi i loko o ka uhi / waho papa: Pre-oxidized non-woven lole mea lapalapa-retardant, kiʻekiʻe-mehana kū'ē a breathable, a hiki ke hoʻohana 'ia e like me ka papa kuhikuhiE o ke ahi e pale aku i ka hoʻololi 'ana o ke ahi a me ke kiʻekiʻe wela, e pale ana i ka ili o ke ahi; ke hui pū ʻia me ka aramid, hiki iā ia ke hoʻomaikaʻi i ka pale ʻana a me ka pale ʻana i ka waimaka.
· Hoʻohana ʻia no ka wiliwili ʻana i nā pale mask, nā mīkina lima pale wela, nā ʻāpana o ka poʻe hana metala, a me nā mea ʻē aʻe, e pale aku i ka lele ʻana a me ka radiation wela kiʻekiʻe (me ke kūpaʻa mahana pōkole ma luna o 300°C).
· Nā lako e pakele ai i ka ulia pōpilikia: E like me nā pākeʻe ahi, nā mea kānana pale pale huna, hiki ke wahī i ke kino a i ʻole ka uahi kānana i ka wā o ke ahi (he mea nui loa ka uahi haʻahaʻa a me ka ʻona ʻole).
2. 'Oihana pale wela wela a me ka insulation
· Nā mea hana hoʻonaʻauaoʻenehana: Hoʻohanaʻia e like me ka uhi o loko o nā paipu wela kiʻekiʻe, nā pads insulation boiler, a me nā mea'ē aʻe, no ka ho'ēmiʻana i ka wela a iʻole ka hoʻololiʻana (ke kū'ē lōʻihi i ka 200 ° C a ma luna o nā kaiapuni).
· Nā mea hana hale pale ahi: E like me ka hoʻopiha piha ʻana i nā pale pale ahi a me nā pale ahi i nā hale kiʻekiʻe, a i ʻole nā mea hoʻopili kelepona, e hoʻopaneʻe i ka hoʻolaha ʻana o ke ahi (e hālāwai me ka GB 8624 fire resistance grade B1 a ma luna o nā koi).
· Ka pale ʻana i nā mea hana kiʻekiʻe: E like me nā pale umu, nā uhi insulation wela no nā kiln a me nā umu, e pale aku i nā limahana mai ke ahi ʻana i ka wela wela o nā mea hana.
3. Nā māla kānana wela kiʻekiʻe
· Ke kānana ʻana i ka uahi ʻenehana: ʻO ka mahana o ka uahi kinoea mai nā ʻōpala ʻōpala, nā wili kila, nā kapuahi hoʻoheheʻe kemika pinepine a hiki i 200-300°C, a loaʻa nā kinoea acidic. Pre-oxidized non-woven lole mea kū'ē i ke kiʻekiʻe wela a me ka corrosion, a hiki ke hoʻohana 'ia e like me ke kumu kumu no ka kānanaʻeke aiʻole kānana cylinders, efficiently kānana.
4. Nā hiʻohiʻona kūikawā ʻē aʻe
ʻO nā mea kōkua Aerospace: hoʻohana ʻia e like me nā ʻāpana insulation pale ahi i loko o nā keʻena mokuahi a me nā pahu hoʻoheheʻe wela a puni nā ʻenekini rocket (pono e hoʻoikaika ʻia me nā resins kūpaʻa kiʻekiʻe).
ʻO nā mea hoʻoheheʻe uila: Hoʻohana ʻia e like me ka insulating gaskets i nā ʻenekini wela a me nā mea hoʻololi, hiki iā lākou ke hoʻololi i nā mea asbestos kuʻuna (non-carcinogenic a ʻoi aku ka maikaʻi o ke kaiapuni).
Iv. Nā Pōmaikaʻi a me nā Kūlana Hoʻomohala o Pre-Oxidized fiber Nonwoven Fabrics
Pōmaikaʻi: Ke hoʻohālikelike ʻia me nā mea pale ahi maʻamau (e like me ka asbestos a me ke aniani fiber), ʻo ka fiber pre-oxygenated fiber non-woven fabric he non-carcinogenic a ʻoi aku ka maʻalahi. Ke hoʻohālikelike ʻia me nā fiber kiʻekiʻe e like me ka aramid, he haʻahaʻa haʻahaʻa kona kumu kūʻai (e pili ana i 1/3 a 1/2 o ka aramid) a kūpono ia no ka hoʻohana ʻana i ka batch i nā hiʻohiʻona a me ke kiʻekiʻe-end flame retardant.
ʻAno: Hoʻonui i ka paʻa a me ka kānana pono ʻana o nā lole i ulana ʻole ʻia ma o ka hoʻomaʻemaʻe fiber (e like me ka fine denier pre-oxygenated filaments, diameter <10μm); E hoʻomohala i nā ʻano hana hoʻoponopono kaiapuni me ka formaldehyde haʻahaʻa a ʻaʻohe mea hoʻopili; Hoʻohui ʻia me nā nanomaterials (e like me ka graphene), hoʻomaikaʻi hou ia i ke kūpaʻa kiʻekiʻe-mehana a me nā waiwai antibacterial.
I ka hopena, ka noi o pre-oxidized fibers i loko o nā lole i ulana ʻole ʻia e pili ana i kā lākou mau mea i hoʻohui ʻia o ka "flame retardancy a me ke kūpaʻa wela kiʻekiʻe" e hoʻoponopono ai i nā hemahema hana o nā mea kuʻuna i ka wela wela a me ka wela wela. I ka wā e hiki mai ana, me ka hoʻonui ʻana i ka palekana o ka ʻoihana a me nā kūlana pale ahi, e hoʻonui hou ʻia kā lākou mau hiʻohiʻona noi.
