Aramid 1313 yakatanga kubudirira kugadzirwa neDuPont muUnited States, uye kugadzirwa kwemaindasitiri kwakaonekwa muna 1967, uye chigadzirwa chakanyoreswa seNomex® (Nomex).Iyi fiber yakapfava, chena, yakatetepa, yakapfava uye inopenya.Chitarisiko chayo chakafanana neicho cheakajairwa makemikari fibers, asi ine anoshamisa "anoshamisa mabasa":
Durable thermal kugadzikana.
Chinhu chinonyanya kuzivikanwa chearamid 1313 ndechekudzivirira kwayo kwekushisa kwepamusoro, iyo inogona kushandiswa kwenguva yakareba pa220 ℃ pasina kuchembera.Kubudirira kwemagetsi ayo uye michina yemagetsi inogona kuchengetedzwa kwemakore gumi, uye kugadzikana kwayo kwechimiro kwakanakisa.Thermal shrinkage rate inenge 1% ingori 1% chete, uye haizodziviriri, imbrittle, kupfava kana kunyunguduka kana ichinge yaiswa kune tembiricha yepamusoro ye300 ° C kwenguva pfupi., kugadzikana kwekushisa kwakadaro kwakasiyana pakati pezvino organic tembiricha-resistant fibers.
Kunyanya kunonoka kwemoto.
Isu tinoziva kuti chikamu cheokisijeni vhoriyamu inodiwa kuti zvinhu zvipise mumhepo inonzi inodzikamisa oxygen index.Iyo yakakura iyo inomisikidza okisijeni index, zviri nani kuita kwayo murazvo wemoto.Kazhinji, iyo okisijeni iri mumhepo ndeye 21%, uye iyo inogumira oksijeni index yearamid 1313 yakakura kupfuura 28%.Hunhu uhwu hunobva muchimiro chayo chemolecular inoita kuti aramid 1313 isadzore moto, saka ine mukurumbira we "fireproof fiber".
Yakanakisa magetsi ekudzivirira.
Aramid 1313 ine yakanyanya kuderera dielectric garage, uye inherent dielectric simba rinoigonesa kuchengetedza yakanakisa kuvharirwa kwemagetsi pasi pekushisa kwepamusoro, tembiricha yakaderera, uye hunyoro hwepamusoro.㎜, inozivikanwa seyakanakisa insulating zvinhu munyika.
Kunyatsogadzikana kwemakemikari.
Aramid 1313 is a linear macromolecule inoumbwa nemaamide bond anobatanidza aryl mapoka.Mukristaro yayo, mabhondi ehydrogen anorongwa mundege mbiri kuti dziite matatu-dimensional chimiro.Ichi chakasimba chehydrogen bond chinoita kuti chimiro chayo chemakemikari chinyatsogadzikana uye chinogona Kudzivirira kune yakanyanya kunyudzwa inorganic acids uye mamwe makemikari, hydrolysis uye steam corrosion.
Yakanakisa michina zvinhu.
Aramid 1313 chinhu chinochinjika chepolymer chine kuomarara kwakaderera uye kurebesa kwakakwirira, zvichiita kuti ive yakafanana spinnability seyakajairika fiber.Inogona kugadzirwa kuita machira akasiyana-siyana kana machira asiri akarukwa nemichina yakajairwa yekuruka, uye haipfeki uye isingabvarura.zvakafara zvikuru.
Super radiation resistance.
Aramid 1313 ine kupikisa kwakanyanya kune α, β, χ mwaranzi uye ultraviolet mwaranzi.Ne 50Kv X-ray mwaranzi kwemaawa 100, simba refayibha rinoramba riri 73% yepakutanga, uye polyester kana naironi panguva ino yatove hupfu.Iyo yakasarudzika uye yakagadzikana chimiro chemakemikari chinopa aramid 1313 ine yakanakisa zvivakwa.Kuburikidza nekushandiswa kwakazara kwezvivakwa izvi, nhevedzano yemabasa matsva uye zvigadzirwa zvitsva zvinoramba zvichigadzirwa, uye minda yekushandisa iri kuwedzera nekufara, uye mukurumbira uri kuwedzera nekukwirira.
Zvipfeko zvakakosha zvekudzivirira.
Aramid 1313 jira haripisi, kudonha, kunyunguduka uye utsi kana rasangana nemoto, uye rine yakanakisa kusapisa moto.Kunyanya kana wasangana nekupisa kwakanyanya kwe900-1500 ℃, jira rejira rinokurumidza kugadzirwa nekabhoni uye kukora, richigadzira yakasarudzika yekupisa yekuvharisa barriers kudzivirira mupfeki kutiza.Kana zvishoma antistatic fiber kana aramid 1414 yakawedzerwa, inogona kunyatsodzivirira jira kubva pakuputika uye kudzivirira njodzi dzemheni arc, magetsi arc, static magetsi, moto uye zvichingodaro.Aramid 1313 non-ferrous fibers inogona kushandiswa kugadzira zvipfeko zvakasiyana-siyana zvekudzivirira zvakadai semasutu ekubhururuka, masutu ekurwa nemakemikari, masutu ekudzivirira moto, mahovhorosi echoto, mahovhorosi emagetsi, masutu akaenzana, mahovhorosi anodzivirira mwaranzi, masutu ekudzivirira kemikari, high-voltage shielding masutu, etc. Aviation, aerospace, mauto yunifomu, moto kudzivirira, petrochemical, magetsi, gasi, metallurgy, mijaho uye mamwe akawanda minda.Pamusoro pezvo, munyika dzakabudirira, machira eAramid anoshandiswawo zvakanyanya semachira epahotera, machira anoponesa upenyu, shongedzo dzemumba dzisingadziviriri moto, maayina ebhodhi anovhara, magirovhosi emukicheni, uye mapijama anodzivirira moto kudzivirira vakwegura nevana.
High tembiricha sefa zvinhu.
Iyo yakakwira tembiricha kuramba, kugadzikana kwedimensional uye makemikari kuramba yearamid 1313 inoita kuti ive inotonga mumunda wepamusoro tembiricha sefa midhiya.Aramid sefa midhiya inoshandiswa zvakanyanya mumakemikari zvidyarwa, zvinopisa magetsi zvidyarwa, kabhoni nhema zvirimwa, simende zvirimwa, lime, coking zvidyarwa, kunyungudutsa, asphalt zvirimwa, pendi zvidyarwa, pamwe nepamusoro-tembiricha flues uye mhepo inopisa mumagetsi arc furnaces, mafuta boilers, uye incinerators Filtration haigoni chete zvinobudirira kubvisa guruva, asiwo kuramba kemikari kurwisa utsi hunokuvadza, uye panguva imwe chete kufambisa kudzoreredza anokosha simbi.
Muzinga wekugadzira zvinhu.
Aramid 1313 structural material paper inogona kushandiswa kugadzira biomimetic multi-layer honeycomb structural board, ine simba rakatanhamara/huremu reshiyo uye rigidity/uremu reshiyo (inenge 9 nguva iyo yesimbi), huremu huremu, kupikisa, kuramba kwemoto, kuvharisa, uye kusimba.Iyo ine hunhu hwekurambira kwecorrosion, kuramba kuchembera uye yakanaka electromagnetic wave permeability.Yakakodzera kugadzirwa kwebroadband wave-transmitting zvinhu uye hombe yakaomesesa yechipiri yekusimbisa zvimiro zvikamu pandege, zvombo zvinokandwa uye satellite (semapapiro, fairings, cabin linings, mikova, nezvimwewo).Floor, cargo hold and partition wall, etc.), zvakare yakakodzera kugadzirwa kweyachts, mabhoti emujaho, zvitima zvinomhanya uye zvimwe zvimiro zvesangweji zvepamusoro.
