Nā Huahana lole ulana ʻole Polyimide

I. Nā ʻano koʻikoʻi o ka lole Polyimide Nonwoven: ʻO ka mea hana holoʻokoʻa ma nā wahi koʻikoʻi loa

Ke hoʻohana nei i nā pono kūlohelohe o ka mea PI a me nā waiwai kūikawā o ke kaʻina hana hydroentanglement, hōʻike ka lole nonwoven polyimide i ʻekolu mau ʻano koʻikoʻi e lanakila ai i nā palena hana o nā olonā organik a me nā inorganic maʻamau i nā hiʻohiʻona wela kiʻekiʻe, flame-retardant, kū i ka wā, a me nā hiʻohiʻona i hoʻohui ʻia i ka hana:

1. Paʻa Mahana Kiʻekiʻe + Palekana ʻAna i ka Lapaʻau Intrinsic: He Palekana no nā Kaiapuni Pōpilikia Kiʻekiʻe

ʻOi aku ka maikaʻi o ke kūpaʻa wela i hoʻohālikelike ʻia me nā mea maʻamau: ʻAʻole e like me ka aramid (mahana lawelawe lōʻihi: 204°C) a me ka PTFE (mahana lawelawe lōʻihi: 260°C), mālama ka polyimide i ka pono o ke kūkulu ʻana ma lalo o ka hana mau ma 260°C, me ka hoʻomanawanui pōkole a hiki i ka 400°C. ʻAʻole i hōʻino ʻia ke ʻano o ka fiber hydroentangled, e hōʻike ana i nā hōʻailona o ka ʻelemakule a i ʻole ka hōʻino ʻana ma hope o 1.5 mau makahiki o ka hoʻohana mau ʻana i nā noi e like me ka puhi ʻana i nā ʻōpala a me nā wahi wela kiʻekiʻe o ka metallurgical, e hopena ana i kahi ola lawelawe ma mua o ʻekolu manawa o nā mea aramid.

Pale ahi kiʻekiʻe loa: Me ka ʻole o ka pono no nā mea hoʻohui pale ahi, loaʻa i ka mea kahi helu oxygen palena (LOI) o 38% (ʻoi aku ka nui ma mua o PTFE 28% a me aramid 29%). ʻAʻole ia e ʻā a hoʻoheheʻe paha i ka wā e hōʻike ʻia ai i ka lapalapa, hoʻopau koke ia iā ia iho ma hope o ka wehe ʻana o ka lapalapa, a ʻaʻole hoʻokuʻu i nā kinoea ʻawahia i ka wā e puhi ai. Pale pono kēia i ka laha ʻana o ka lapalapa, e hoʻoponopono ana i nā hemahema koʻikoʻi o nā mea pale ahi kuʻuna e like me nā ʻeha i hoʻoulu ʻia e ka hoʻoheheʻe ʻana a me ka hoʻokuʻu ʻana o ka uahi ʻawahia.

2. Ke Kū'ē ʻana i ke Aniau Holoʻokoʻa + Ke Kūpaʻa Mekanika: He Pale Kaua Paʻa no nā Kūlana ʻOʻoleʻa

ʻO ke kūpaʻa kūʻokoʻa i ka pala a me ka ʻelemakule: Hōʻike ka lole i ke kūpaʻa maikaʻi loa i ka hapa nui o nā media acid-base (e laʻa, 10% sulfuric acid, 15% sodium hydroxide), nā mea hoʻoheheʻe organik, a me ka radiation UV, me ka nalowale o ka ikaika tensile o ≤8% ma hope o 60 mau lā o ka hoʻokomo ʻana. ʻAʻole ia e hōʻike i ka embrittlement a i ʻole ka degradation ma lalo o ka hōʻike lōʻihi ʻana i ka UV waho, ka makū, a me ka wela, e hoʻokō ana i kahi ola lawelawe o 8-10 mau makahiki i ka mana nukelea a me nā noi ʻenekinia waho—ʻoi aku ma mua o 10 mau manawa o nā mea polyester maʻamau.

Nā waiwai mechanical maikaʻi loa: Me ka nui o ke kaula o 1.41 g/cm³ a ​​me ka ikaika haki lōʻihi o 600 N/5×20 cm, hāʻawi ia i 20 manawa o ka ikaika o ka lole polypropylene ma ke kaumaha like. Ma hope o ka hydroentanglement, hiki ke kūpaʻa haehae i ≥50 N, me ka paʻa ʻana o ka ikaika pulu 100%. Lanakila kēia i ka brittleness haʻahaʻa o nā kaula basalt a me ka ikaika mechanical lawa ʻole o ka PTFE, e kūpono ai no nā noi kaumaha a me nā noi hoʻoluhi ikaika.

3. Hoʻohālikelike Hana + Hana Hoʻololi: He Kumu Hoʻohālikelike no ka Hoʻopilikino ʻana

Mālama ka Hydroentanglement i ka hana o nā mea: Hōʻoia ke kaʻina hana spunlace kiʻekiʻe i ka hoʻopili mālie ʻana o ka fiber me ka ʻole o ka hōʻino e pili ana me ke kuʻi ʻana i ka nila. He palupalu ka huahana hopena (paʻakikī ≤50 Shore A) me ka drape maikaʻi loa, e ʻae ana i ka ʻoki pololei, ka humuhumu, a me ka thermoforming. Hoʻoponopono kēia i nā pilikia hana o nā felts nila PI kuʻuna, he paʻakikī a palupalu pinepine, ʻoiai e hāʻawi ana i kahi ʻili laumania, ʻaʻohe burr kūpono no ka hoʻohui ʻana i nā ʻāpana kikoʻī.

Ka hiki ke hana nui: Ma o ka hoʻololi ʻana i ka ʻili a i ʻole nā ​​​​ʻano hana i hui pū ʻia, hiki ke hāʻawi ʻia ka lole me nā hana holomua he nui. No ka laʻana, ma hope o ka mālama ʻana i ka alkali a me ka hoʻouka ʻana me Fe₃O₄ a me nā nanoparticles Ag, loaʻa iā ia ka hopena pale electromagnetic kiʻekiʻe (77 dB) a me ka reflectivity haʻahaʻa loa (≤-10 dB). Ke hui pū ʻia me nā nanofibers, hōʻike ia i nā waiwai kānana wela kiʻekiʻe a me nā antibacterial, e hoʻokō ana i nā koi like ʻole i ka camouflage koa a me nā noi lapaʻau kiʻekiʻe.

II. Nā kahua noi mua o ka lole ulana ʻole Polyimide: Nā hoʻonā hiki ʻole ke hoʻololi ʻia no nā hiʻohiʻona kiʻekiʻe

Ma muli o nā ʻano i luna, ua lilo ka lole polyimide nonwoven i mea nui i ka kānana wela kiʻekiʻe, ka palekana kūikawā, nā mea uila/koa, a me nā kahua lapaʻau holomua, e lawelawe ana i nā noi pilikia kiʻekiʻe, koi nui, a me ke ola lōʻihi:

1. Kānana Wela Kiʻekiʻe a me ka Palekana Kaiapuni: ʻO ka Hoʻonā Hoʻomaʻemaʻe Mua no nā Kūlana Koʻikoʻi

Kānana kinoea flue wela kiʻekiʻe: Hoʻohana ʻia i loko o nā ʻeke kānana no nā hale hana puhi ʻōpala a me nā kānana wehe lepo i nā hale hana mana lanahu, hopu pono ka lole i ka lepo maikaʻi a me nā ʻāpana ʻino ma 300°C, me ka pololei o ka kānana o 0.5 μm. ʻO kona LOI kiʻekiʻe (38%) e pale aku i nā pilikia kuni i hoʻokumu ʻia e ka potassium a me ka sodium i loko o ka lehu lele, e hāʻawi ana i kahi ola lawelawe ʻoi aku ma mua o ka pālua o nā mea kānana PPS.

Kānana wela kiʻekiʻe ʻoihana: Hoʻokomo ʻia nā noi i nā lole kānana no nā hoʻokuʻu ʻana o ke kahua hui ʻakipa a me nā ʻeke kānana no ka kānana solvent wela kiʻekiʻe i nā hale hana kemika. Kūpaʻa ka lole i nā mahana 260°C a me ka pala o ka solvent organik, ʻaʻole ia e hoʻopili i nā ʻāpana filtrate, hōʻoia i ka maʻemaʻe o ka huahana, a hōʻike i ka hana anti-clogging maikaʻi loa, e hōʻemi ana i ke kūpaʻa kānana ma 30% i hoʻohālikelike ʻia me nā kānana fiber aniani kuʻuna.

2. Ka Palekana Kūikawā a me ka Palekana: He Ola i nā Kūlana Pōpilikia Kiʻekiʻe

Nā lako palekana pilikino: Hoʻohana ʻia ma ke ʻano he uhi no nā lole pale ahi metallurgical a me ka lole no nā lole pale wela o nā mea kinai ahi, mālama ka mea i ka pono o ke kūkulu ʻana ma 260°C, me ka conductivity thermal o 0.03 W/(m·K) wale nō, e pale pono ana i ka radiation wela kiʻekiʻe. Hāʻawi kona ʻano palupalu a hanu i ka ʻoluʻolu nui ma mua o nā mea huluhulu pōhaku kuʻuna, e kūpono ai no nā hana wela kiʻekiʻe i ka metallurgy a me ke kinai ahi.

Nā huahana palekana pilikia: ʻO nā noi e komo pū me ka lole halelewa pale ahi koa a me nā pale lapalapa no nā wahi pilikia kiʻekiʻe. ʻO ka mea pale lapalapa a kūpaʻa i ka wā, ʻaʻole ia e pala ma lalo o ka makū o waho, ka wela, a i ʻole ka ʻike UV ikaika, e lawelawe ana ma ke ʻano he pale paʻa paʻa. ʻO kona nui i pelu ʻia e hiki ai ke hoʻolaha koke i nā pilikia, kūpono no ka camouflage koa a me ka pane ʻana i nā hanana kemika.

3. Nā noi uila a me nā koa: ʻO ke kumu hana o nā lako hana kiʻekiʻe

Nā mea pale uila: Hoʻohana ʻia i loko o nā lole huna radar a me ka padding anti-interference no nā mea uila, hoʻokō ka lole i ka omo nalu electromagnetic maikaʻi ma ka laulā broadband 8.2-40 GHz ma hope o ka hoʻouka ʻana i nā ʻāpana magnetic a me ka uhi kālā electroless, me ka pono pale a hiki i ka 77 dB. Mālama ia i ka hana paʻa ma 250°C, e pale ana i nā lako koa mai ka hoʻopilikia electromagnetic ʻoiai e hiki ai ke hūnā infrared.

Nā ʻāpana pale wela kiʻekiʻe: ʻO nā noi e komo pū me nā liners pale no nā ʻenekini mokulele a me ka lole encapsulation no nā ʻāpana uila kiʻekiʻe. Me ka ikaika dielectric ≥25 kV/mm ma 260°C a ʻaʻohe hōʻino ʻana i ka hana pale, kūʻē ka lole i ka pala e nā aila a me nā wahie, e pale ana i nā kaapuni pōkole i nā ʻāpana uila a hoʻokō i nā pono o ka aerospace a me nā ʻoihana kaʻa premium.

4. Nā lole lapaʻau a me nā lole kiʻekiʻe: Ke hōʻoiaʻiʻo nei i ka palekana a me ka maʻemaʻe

Nā huahana palekana lapaʻau: Hoʻohana ʻia i loko o nā lole ʻoki kino sterilizable wela kiʻekiʻe a me nā substrates lole sterile, hāʻawi ka mea i ka biocompatibility maikaʻi loa (ʻaʻole allergenic, ʻaʻole hoʻonāukiuki) a kū i ka sterilization mahu 134°C me ka ʻole o ka hoʻokahe ʻana o ka fiber, e kūlike ana me nā kūlana sterile GMP. Hōʻoiaʻiʻo ia i ka palekana hana i nā kūlana lapaʻau holomua e like me ka hoʻoili ʻana o nā kino a me ke ʻoki kino minimally invasive.

Nā lole hana: ʻO nā noi e komo pū me nā lole pale ahi no ka heihei a me nā lole pale no ka ʻoihana nukelea. ʻO ka lole pale ahi mau loa, hanu, a ʻoluʻolu hoʻi, ʻaʻole ia e hoʻonāukiuki i ka ʻili i ka wā e hoʻohana lōʻihi ai. Kūʻē pū ia i ka radiation a me ka pala kemika, e pale ana i nā limahana mai nā kuni a me ka ʻike radioactive ma nā wahi kūikawā e like me nā motorsports a me ka mālama ʻana i ka mana nukelea.

E pili ana iā Yongdeli: He mea hana loea o nā lole ulana ʻole Polyimide

Hoʻokele ʻo Changshu Yongdeli Spunlaced Nonwoven Co., Ltd. i nā laina hana hana ponoʻī no nā lole polyimide nonwoven, e hāʻawi ana i nā huahana i hana kūikawā ʻia me nā kaumaha mai 60-500 g/㎡ a me ka laulā o 0.2-3.2 m. Hāʻawi pū ka ʻoihana i nā koho ma hope o ka mālama ʻana me ka uhi magnetic, nanofiber compositing, a me ka singeing/calendering.

No nā laʻana huahana a i ʻole nā ​​​​​​hoʻonā i hoʻopilikino ʻia, e ʻoluʻolu e kelepona mai iā mākou.
