He aha ka Aramid Fiber a me kona mau pono?

1. Nā waiwai mīkini maikaʻi
ʻO ka interposition aramid kahi polymer palupalu, ʻoi aku ka ikaika o ka haki ma mua o ka polyester maʻamau, pulupulu, nylon, a me nā mea ʻē aʻe, ʻoi aku ka nui o ka elongation, palupalu i ka pā, maikaʻi ka spinnability, hiki ke hana ʻia i nā ʻano lahilahi like ʻole, lōʻihi o nā olonā pōkole a me nā filaments, ma ke ʻano laulā, hana ʻia nā mīkini lole me nā helu hilo like ʻole i ulana ʻia i loko o nā lole, nā lole i ulana ʻole ʻia, ma hope o ka hoʻopau ʻana, e hoʻokō i nā koi o nā wahi like ʻole o nā lole pale.

2. Maikaʻi loa ke kūpaʻa ʻana i ka lapalapa a me ka wela
ʻO ka helu kuhikuhi oxygen palena (LOI) o ka m-aramid he 28, no laila ʻaʻole ia e hoʻomau i ke kuni ʻana i ka wā e haʻalele ai i ka lapalapa. Hoʻoholo ʻia nā waiwai pale lapalapa o ka m-aramid e kona ʻano kemika ponoʻī, e lilo ia i fiber pale lapalapa mau loa ʻaʻole e hōʻino a nalowale paha i kona mau waiwai pale lapalapa me ka manawa a i ʻole ka holoi ʻana. He paʻa ka m-aramid i ka wela a hiki ke hoʻohana mau ʻia ma 205°C a mālama i ka ikaika kiʻekiʻe ma nā mahana ma mua o 205°C. He mahana palaho kiʻekiʻe ko ka m-aramid a ʻaʻole e heheʻe a kulu paha i nā mahana kiʻekiʻe, akā hoʻomaka wale e puhi i nā mahana ma mua o 370°C.

3. Nā waiwai kemika paʻa
Ma waho aʻe o nā waikawa ikaika a me nā kumu, ʻaʻole i hoʻopilikia ʻia ka aramid e nā mea hoʻoheheʻe organik a me nā aila. ʻAneʻane like ka ikaika pulu o ka aramid me ka ikaika maloʻo. ʻOi aku ka maikaʻi o ke kūpaʻa o ka mahu wai saturated ma mua o nā olonā organik ʻē aʻe.
He ʻano ʻike iki ka Aramid i ka mālamalama UV. Inā e hōʻike ʻia i ka lā no ka manawa lōʻihi, e nalowale ana ka nui o ka ikaika a no laila e pale ʻia me kahi papa pale. Pono kēia papa pale e hiki ke pale i ka hōʻino ʻana i ka iwi aramid mai ka mālamalama UV.

4. Ke kū'ē ʻana i ka radiation
He maikaʻi loa ke kūpaʻa ʻana o ka radiation o nā aramid interposition. No ka laʻana, ma lalo o 1.72x108rad/s o ka r-radiation, e mau ana ka ikaika.

5. Ka Paʻa
Ma hope o 100 holoi ʻana, hiki nō i ka ikaika haehae o nā lole m-aramid ke hiki aku ma mua o 85% o ko lākou ikaika mua. ʻOi aku ke kiʻekiʻe o ke kūpaʻa wela o nā para-aramids ma mua o nā inter-aramids, me ka pae mahana hoʻohana mau o -196°C a i 204°C a ʻaʻohe palaho a heheʻe paha ma 560°C. ʻO ke ʻano koʻikoʻi o ka para-aramid ʻo ia kona ikaika kiʻekiʻe a me ka modulus kiʻekiʻe, ʻoi aku kona ikaika ma mua o 25g/dan, ʻo ia hoʻi he 5 ~ 6 mau manawa o ke kila kiʻekiʻe, 3 mau manawa o ke aniani fiber a me 2 mau manawa o ka olonā ʻoihana nylon ikaika kiʻekiʻe; ʻo kona modulus he 2 ~ 3 mau manawa o ke kila kiʻekiʻe a i ʻole ke aniani fiber a me 10 mau manawa o ka olonā ʻoihana nylon ikaika kiʻekiʻe. ʻO ke ʻano ʻili kū hoʻokahi o ka pulp aramid, i loaʻa ma o ka fibrillation ʻili o nā olonā aramid, hoʻomaikaʻi nui i ka paʻa ʻana o ka hui a no laila kūpono ia ma ke ʻano he olonā hoʻoikaika no nā huahana friction a me ka sila. ʻO Aramid Pulp Hexagonal Special Fiber I Aramid 1414 Pulp, flocculent melemele māmā, palupalu, me nā plumes he nui, ikaika kiʻekiʻe, kūpaʻa maikaʻi o ka dimensional, ʻaʻole brittle, kūpaʻa i ka mahana kiʻekiʻe, kūpaʻa i ka corrosion, paʻakikī, emi haʻahaʻa, kūpaʻa abrasion maikaʻi, ʻili ākea nui, pili maikaʻi me nā mea ʻē aʻe, mea hoʻoikaika me ka hoʻihoʻi ʻana o ka makū o 8%, ka lōʻihi awelika o 2-2.5mm a me ka ʻili o 8m2/g. Hoʻohana ʻia ia ma ke ʻano he mea hoʻoikaika gasket me ka kūpaʻa maikaʻi a me ka hana sila, a ʻaʻole ia e hōʻino i ke olakino kanaka a me ke kaiapuni, a hiki ke hoʻohana ʻia no ka sila ʻana i ka wai, ka ʻaila, nā waikawa a me nā alkali ikaika ʻē aʻe a me ka ikaika waena. Ua hōʻoia ʻia ua like ka ikaika o ka huahana me 50-60% o nā huahana i hoʻoikaika ʻia me ka fiber asbestos ke hoʻohui ʻia ma lalo o 10% o ka slurry. Hoʻohana ʻia ia e hoʻoikaika i nā mea friction a me nā mea sila a me nā huahana hana ʻē aʻe, a hiki ke hoʻohana ʻia ma ke ʻano he koho ʻē aʻe i ka asbestos no nā mea sila friction, ka pepa insulation pale wela kiʻekiʻe a me nā mea hui i hoʻoikaika ʻia.
