Aramid 1313 idapangidwa bwino koyamba ndi DuPont ku United States, ndipo kupanga mafakitale kudachitika mu 1967, ndipo malondawo adalembetsedwa ngati Nomex® (Nomex).Uwu ndi ulusi wofewa, woyera, wowonda, wonyezimira komanso wonyezimira.Maonekedwe ake ndi ofanana ndi ulusi wamba wamankhwala, koma ali ndi "ntchito zodabwitsa" zodabwitsa:
Kukhazikika kwamafuta okhazikika.
Chodziwika kwambiri cha aramid 1313 ndi kukana kwake kutentha, komwe kungagwiritsidwe ntchito kwa nthawi yayitali pa 220 ℃ osakalamba.Mphamvu yamagetsi ndi makina ake amatha kusungidwa kwa zaka 10, ndipo kukhazikika kwake ndikwabwino kwambiri.Kutentha kwa kutentha kwa pafupifupi 1% ndi 1% yokha, ndipo sikungachepetse, kusungunula, kufewetsa kapena kusungunuka pamene kutentha kwapamwamba kwa 300 ° C kwa nthawi yochepa., kukhazikika kwa kutentha koteroko kumakhala kwapadera pakati pa ulusi wamakono wosamva kutentha.
Kuchedwa kwabwino kwa moto.
Tikudziwa kuti kuchuluka kwa voliyumu ya okosijeni yofunikira kuti zinthu ziwotche mumlengalenga zimatchedwa indexing oxygen index.Mlozera wocheperako wa okosijeni ukakulirakulira, m'pamenenso ntchito yake yolepheretsa kuyatsa imakhala yabwino.Kawirikawiri, mpweya wa mpweya mumlengalenga ndi 21%, ndipo kuchepetsa mpweya wa aramid 1313 ndi wamkulu kuposa 28%.Chikhalidwe ichi chochokera ku mamolekyu ake omwe amachititsa kuti aramid 1313 ikhale yosasunthika ndi moto, choncho imakhala ndi mbiri ya "fireproof fiber".
Kusungunula kwabwino kwamagetsi.
Aramid 1313 ili ndi ma dielectric otsika kwambiri, ndipo mphamvu yake ya dielectric imathandiza kuti ikhale yosasunthika bwino kwambiri pa kutentha kwambiri, kutentha pang'ono, komanso chinyezi chambiri.㎜, imadziwika kuti ndi zida zabwino kwambiri zotetezera padziko lapansi.
Kukhazikika kwapadera kwamankhwala.
Aramid 1313 ndi macromolecule yozungulira yopangidwa ndi ma amide bond olumikiza magulu a aryl.Mu kristalo wake, zomangira za haidrojeni zimakonzedwa mu ndege ziwiri kuti zipange mawonekedwe atatu.Chomangira cholimba cha haidrojenichi chimapangitsa kuti mankhwala ake azikhala okhazikika kwambiri ndipo amatha Kusamva ma asidi ambiri osakhazikika komanso mankhwala ena, hydrolysis ndi dzimbiri la nthunzi.
Wabwino makina katundu.
Aramid 1313 ndi chinthu chosinthika cha polima chokhala ndi kuuma pang'ono komanso kutalika kwambiri, ndikupangitsa kuti ikhale yozungulira ngati ulusi wamba.Itha kupangidwa kukhala nsalu zosiyanasiyana kapena nsalu zosalukidwa ndi makina wamba opota, ndipo imakhala yosagwira komanso yosagwetsa.yotakata kwambiri.
Super radiation kukana.
Aramid 1313 ili ndi kukana kwambiri kwa α, β, χ cheza ndi cheza cha ultraviolet.Ndi 50Kv X-ray ma radiation kwa maola 100, mphamvu ya fiber imakhalabe 73% yapachiyambi, ndipo poliyesitala kapena nayiloni panthawiyi yakhala kale ufa.Mapangidwe apadera komanso okhazikika amankhwala amapatsa aramid 1313 ndi zinthu zabwino kwambiri.Kupyolera mu kugwiritsiridwa ntchito kwathunthu kwa zinthuzi, mndandanda wa ntchito zatsopano ndi zatsopano zimapangidwira mosalekeza, ndipo magawo ogwiritsira ntchito akuchulukirachulukira, ndipo kutchuka kukukulirakulira.
Zovala zapadera zodzitetezera.
Nsalu ya Aramid 1313 siwotcha, kudontha, kusungunuka ndi utsi ikakumana ndi moto, ndipo imakhala ndi mphamvu yabwino yoletsa moto.Makamaka mukakumana ndi kutentha kwambiri kwa 900-1500 ℃, pamwamba pansaluyo imakhala ndi mpweya wochuluka komanso wokhuthala, ndikupanga chotchinga chapadera chamafuta kuti chiteteze wovala kuti asathawe.Ngati kaphatikizidwe kakang'ono ka antistatic fiber kapena aramid 1414 kawonjezedwa, kumatha kuteteza nsaluyo kuti isaphulike ndikupewa kuopsa kwa mphezi, arc yamagetsi, magetsi osasunthika, lawi ndi zina zotero.Aramid 1313 ulusi wopanda chitsulo ungagwiritsidwe ntchito kupanga zovala zosiyanasiyana zodzitchinjiriza monga masuti owuluka, masuti olimbana ndi mankhwala, masuti omenyera moto, maovololo ang'anjo, maovololo owotcherera amagetsi, suti zofananira, maovololo oteteza ma radiation, suti zoteteza mankhwala, high-voltage shielding suits, etc. Ndege, ndege, yunifolomu ya asilikali, chitetezo cha moto, petrochemical, magetsi, gasi, zitsulo, kuthamanga ndi zina zambiri.Kuphatikiza apo, m’mayiko otukuka, nsalu za aramid zimagwiritsidwanso ntchito kwambiri monga nsalu za ku hotelo, njira zopulumutsira moyo, zokongoletsera zapakhomo zosagwira moto, zophimba kusita, magulovu akukhitchini, ndi zovala zogona zoteteza okalamba ndi ana.
Zida zosefera kutentha kwambiri.
Kukana kwa kutentha kwakukulu, kukhazikika kwa mawonekedwe ndi kukana kwa mankhwala kwa aramid 1313 kumapangitsa kuti ikhale yayikulu pagulu lazosefera zotentha kwambiri.Zosefera za Aramid zimagwiritsidwa ntchito kwambiri m'mafakitale amafuta, magetsi otenthetsera magetsi, zomera zakuda za kaboni, zomera za simenti, zomera za laimu, zokokera, zosungunulira, zomera za asphalt, zomera za penti, komanso zitoliro zotentha kwambiri ndi mpweya wotentha m'ng'anjo yamagetsi yamagetsi, mafuta boilers, ndi incinerators Sefa sangathe mogwira kuchotsa fumbi, komanso kukana mankhwala kuukira utsi zoipa, ndipo nthawi yomweyo atsogolere kuchira zitsulo zamtengo wapatali.
Zida zomangira zisa.
Aramid 1313 pepala zinthu zomangira angagwiritsidwe ntchito kupanga biomimetic Mipikisano wosanjikiza uchi structural bolodi, amene ali chapadera mphamvu / kulemera chiŵerengero ndi rigidity / kulemera chiŵerengero (pafupifupi 9 nthawi chitsulo), kulemera kuwala, kukana mphamvu, kukana lawi, kutchinjiriza, ndi durability.Ili ndi mawonekedwe okana dzimbiri, kukana kukalamba komanso kukwanira kwa mafunde a electromagnetic wave.Ndizoyenera kupanga zida zotumizira mafunde a Broadband ndi zida zazikulu zolimba zachiwiri pandege, zoponya ndi ma satelayiti (monga mapiko, ma fairing, zitseko, zitseko, ndi zina).Pansi, katundu wonyamula katundu ndi khoma logawa, etc.), komanso oyenera kupanga ma yachts, mabwato othamanga, masitima othamanga kwambiri ndi ma sangweji ena ochita bwino kwambiri.
