Ua hoʻomohala mua ʻia ʻo Aramid 1313 e DuPont ma ʻAmelika Hui Pū ʻIa, a ua hoʻokō ʻia ka hana ʻenehana ma 1967, a ua hoʻopaʻa inoa ʻia ka huahana ma Nomex® (Nomex).He pulupulu palupalu kēia, keʻokeʻo, lohi, pulu a ʻulaʻula.Ua like kona ʻano me ko nā fiber kemika maʻamau, akā he "hana kupaianaha" kona:
Paʻa wela paʻa.
ʻO ka hiʻohiʻona koʻikoʻi o ka aramid 1313 ʻo kona kūpaʻa wela kiʻekiʻe, hiki ke hoʻohana ʻia no ka manawa lōʻihi ma 220 ℃ me ka ʻole o ka ʻelemakule.Hiki ke mālama ʻia ka maikaʻi o kāna mau mea uila a me ka mechanical no 10 mau makahiki, a ʻoi aku ka maikaʻi o kona kūpaʻa dimensional.ʻO ka nui o ka hoʻohaʻahaʻa wela ma kahi o 1% he 1% wale nō, a ʻaʻole ia e emi, embrittle, palupalu a hoʻoheheʻe ʻia ke ʻike ʻia i kahi mahana kiʻekiʻe o 300 ° C no ka manawa pōkole., ʻokoʻa ka paʻa wela kiʻekiʻe ma waena o nā fibers pale wela kūlohelohe i kēia manawa.
ʻO ka hoʻopaneʻe ahi maikaʻi loa.
Ua ʻike mākou ʻo ka pākēneka o ka nui o ka oxygen i koi ʻia no kahi mea e puhi ai i ka ea i kapa ʻia ʻo ka helu helu oxygen palena.ʻOi aku ka nui o ka helu oxygen palena, ʻoi aku ka maikaʻi o kāna hana pale ahi.ʻO ka maʻamau, ʻo ka ʻike oxygen i ka lewa he 21%, a ʻoi aku ka nui o ka helu oxygen palena o aramid 1313 ma mua o 28%.ʻO kēia hiʻohiʻona i loaʻa mai i kāna ʻano molekala ponoʻī e hana i ka aramid 1313 i ka lapalapa ahi mau loa, no laila ua kaulana ʻo ia he "fireproof fiber".
ʻOi aku ka maikaʻi o ka pale uila.
ʻO ka Aramid 1313 he mau dielectric haʻahaʻa haʻahaʻa loa, a ʻo kona ikaika dielectric inherent hiki iā ia ke mālama i ka insulation uila maikaʻi loa ma lalo o ke kiʻekiʻe wela, haʻahaʻa haʻahaʻa, a me nā kūlana haʻahaʻa kiʻekiʻe.㎜, ʻike ʻia ʻo ia ka mea insulating maikaʻi loa ma ka honua.
Paʻa kemika koʻikoʻi.
ʻO Aramid 1313 kahi macromolecule laina i haku ʻia me nā paʻa amide e pili ana i nā pūʻulu aryl.I loko o kona aniani, ua hoʻonohonoho ʻia nā paʻa hydrogen i ʻelua mau mokulele e hana i kahi ʻano ʻekolu.ʻO kēia paʻa hydrogen ikaika e paʻa loa kona ʻano kemika a hiki ke kūpaʻa i nā ʻakika inorganic nui loa a me nā kemika ʻē aʻe, hydrolysis a me ka ʻinoʻino.
ʻO nā waiwai mechanical maikaʻi loa.
ʻO Aramid 1313 kahi mea polymer maʻalahi me ka ʻoʻoleʻa haʻahaʻa a me ka elongation kiʻekiʻe, e hoʻolilo iā ia i ka spinnability like me nā fiber maʻamau.Hiki ke hana ʻia i loko o nā lole like ʻole a i ʻole nā lole i ulana ʻole ʻia e nā mīkini wili maʻamau, a ʻaʻole hiki ke ʻaʻahu a me ka waimaka.ākea loa.
Kūleʻa pāhawewe nui.
ʻO ka Aramid 1313 ke kū'ē maikaʻi loa i nā kukuna α, β, χ a me ka radiation ultraviolet.Me ka 50Kv X-ray radiation no 100 mau hola, ua mau ka ikaika o ka fiber i 73% o ka mea mua, a ua lilo ka polyester a i ʻole nylon i kēia manawa i pauka.Hāʻawi ka ʻenehana kūʻokoʻa a paʻa i ka aramid 1313 me nā waiwai maikaʻi loa.Ma o ka hoʻohana piha ʻana i kēia mau waiwai, hoʻomohala mau ʻia kahi ʻano o nā hana hou a me nā huahana hou, a ʻoi aku ka laulā o nā kahua noi, a piʻi aʻe ka kaulana.
Nā lole pale kūikawā.
ʻAʻole wela ka lole Aramid 1313, kulu, hoʻoheheʻe a uahi i ka wā e hālāwai ai me ke ahi, a he hopena ahi maikaʻi loa.ʻOi loa i ka wā e hālāwai ai me kahi wela kiʻekiʻe o 900-1500 ℃, e wikiwiki koke ka ʻili o ka lole i carbonized a mānoanoa, e hana ana i kahi pale insulation thermal kū hoʻokahi e pale aku i ka mea lawe mai ka pakele.Inā hoʻohui ʻia kahi liʻiliʻi o ka fiber antistatic a i ʻole aramid 1414, hiki iā ia ke pale pono i ka lole mai ka pohā a pale aku i nā pōʻino o ka uila uila, ka uila uila, ka uila static, ka lapalapa a pēlā aku.Hiki ke hoʻohana ʻia ka Aramid 1313 non-ferrous fibers no ka hana ʻana i nā lole pale kūikawā like ʻole e like me nā lole lele, nā lole pale kemika, nā lole pale ahi, nā lole hoʻoheheʻe ahi, nā lole wili uila, nā lole hoʻohālikelike puʻupuʻu, nā lole pale pale kemika, nā lole pale pale kiʻekiʻe, a me nā mea ʻē aʻe. ʻO Aviation, aerospace, pūʻali koa, pale ahi, petrochemical, uila, kinoea, metallurgy, heihei a me nā māla ʻē aʻe he nui.Eia kekahi, ma nā ʻāina i kūkulu ʻia, ua hoʻohana nui ʻia nā lole aramid e like me nā textiles hōkele, nā ala e ola ai, nā mea hoʻonani pale ahi o ka hale, nā uhi papa hao, nā mīkina lima kīhini, a me nā pajama pale ahi e pale ai i nā ʻelemakule a me nā keiki.
Mea kānana wela kiʻekiʻe.
ʻO ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa dimensional a me ke kūpaʻa kemika o ka aramid 1313 e hoʻomake nui i ke kahua o ka media kānana kiʻekiʻe.Hoʻohana nui ʻia ka media kānana Aramid i nā mea kanu kemika, nā mea kanu wela, nā mea kanu ʻeleʻele kalapona, nā mea kanu sima, nā mea kanu lime, nā mea kanu coking, nā mea hoʻoheheʻe ʻia, nā mea kanu asphalt, nā mea kanu pena, a me nā flues wela kiʻekiʻe a me ka ea wela i nā kapuahi uila. aila boilers, a me incinerators Filtration hiki ole wale wehe i ka lepo, akā, e pale aku i ka hoʻouka kemika o ka uwahi ino, a ma ka manawa like hoʻomaʻamaʻa i ka hoʻihoʻi ʻana o nā metala makamae.
Mea hana honeycomb.
Hiki ke hoʻohana ʻia ka pepa hana ʻo Aramid 1313 e hana i ka biomimetic multi-layer honeycomb structural board, nona ka ikaika koʻikoʻi / ke kaupaona ʻana a me ka rigidity / kaumaha ratio (e pili ana i 9 mau manawa o ke kila), ke kaumaha māmā, ke kūpaʻa hopena, ke kū ʻana o ke ahi, insulation, a me ka lōʻihi.Loaʻa iā ia nā hiʻohiʻona o ke kūpaʻa corrosion, ke kūpaʻa ʻelemakule a me ka permeability hawewe electromagnetic maikaʻi.He kūpono ia no ka hana ʻana i nā mea hoʻouna nalu broadband a me nā ʻāpana koʻikoʻi koʻikoʻi koʻikoʻi ma luna o nā mokulele, nā missiles a me nā satelite (e like me nā ʻēheu, fairings, cabin linings, doors, etc.).ʻO ka papahele, ka paʻa ukana a me ka pā ʻāpana, a me nā mea ʻē aʻe), kūpono hoʻi no ka hana ʻana i nā yachts, nā waʻa heihei, nā kaʻa kaʻa kiʻekiʻe a me nā hale hana sandwich hana kiʻekiʻe.
