1.Ka Hoʻokaʻawale ʻana o nā ʻAramid Fibers
Hiki ke hoʻokaʻawale ʻia nā olonā Aramid i ʻelua ʻano nui e like me ko lākou ʻano kemika like ʻole: ʻo kekahi ʻano i hōʻike ʻia e ke kūpaʻa wela, meso-aramid flame retardant, i ʻike ʻia ʻo poly(p-toluene-m-toluoyl-m-toluamide), i pōkole ʻia ʻo PMTA, i ʻike ʻia ʻo Nomex ma US, a me Aramid 1313 ma Kina; a ʻo kekahi ʻano i hōʻike ʻia e ke kiʻekiʻe o ka ikaika, ke kiʻekiʻe o ka elasticity modulus, a me ke kūpaʻa wela, i ʻike ʻia ʻo poly(p-phenylene terephthalamide), i pōkole ʻia ʻo PPTA, i ʻike ʻia ʻo Kevlar ma US, Technora ma Iapana, Twaron ma Netherlands, Tevlon ma Rusia, a me Tevlon ma Kina. ʻO P-phenylenediamine, i pōkole ʻia ʻo PPTA, ka inoa kālepa o ʻAmelika Hui Pū ʻIa no Kevlar, Iapana no Technora, Netherlands no Twaron, Rusia no Tevlon, Kina i kapa ʻia ʻo aramid 1414.

ʻO ke olonā ʻAramidaHe ʻano fibers kūpaʻa wela kiʻekiʻe, ikaika kiʻekiʻe, a elastic kiʻekiʻe, ʻo nā waiwai mechanical o nā fibers inorganic a me nā fibers organik, ka hana hana, ka density a me nā polyester fibers e like me ka like. I ka manawa like, loaʻa iā ia ke kūpaʻa kemika maikaʻi loa, ke kūpaʻa radiation, ke kūpaʻa luhi, ke kūpaʻa dimensional a me nā waiwai maikaʻi ʻē aʻe a me ka resin rubber me kekahi mau waiwai hoʻopili. I kēia manawa, loaʻa i ka huahana ʻelua ʻano pulp a me ka fiber. E lilo i aerospace, rubber, resin ʻoihana, nā lako uila a me nā lako uila, ka halihali, nā lako haʻuki a me ke kūkulu kīwila a me nā wahi ʻē aʻe o nā mea hou. ʻOi aku ka hoʻomākaukau ʻana o nā mea composite pepa aramid hana kiʻekiʻe hiki ke hoʻohana nui ʻia e like me nā mea insulation uila kiʻekiʻe, nā papa kaapuni paʻi a me nā mea pale nalu electromagnetic a me nā mea ʻē aʻe i mahalo nui ʻia.

2. ʻAramida fiberʻAno o ke kino
He melemele ʻālohilohi ka fiber 1414, a he keʻokeʻo ʻālohilohi ka fiber 1313. ʻElua ʻano fiber me nā fibers pōkole (a i ʻole filament) a me ka pulp fiber (a i ʻole precipitation fiber). Hoʻohana nui ʻia ka filament i nā textiles, rubber a me nā ʻoihana ʻē aʻe, a hoʻohana ka ʻoihana pepa i ka staple fiber a me ka pulp fiber.
