Dzina lazinthu: Aramid Fiber
Munda Wofunsira
Aramid CHIKWANGWANI ndi mtundu watsopano waukadaulo wapamwamba kupanga CHIKWANGWANI, kopitilira muyeso-mkulu mphamvu, modulus mkulu ndi kutentha kugonjetsedwa, asidi ndi alkali kukana, kulemera kuwala, katundu kwambiri, monga 5 ~ 6 nthawi ya waya chitsulo pa mphamvu yake, modulus wa waya wachitsulo kapena galasi la fiber 2 ~ 3 nthawi, kulimba ndi 2 nthawi za waya, ndipo kulemera ndi pafupifupi 1/5 ya waya wachitsulo, kutentha kwa madigiri 560, osasweka, osasungunuka.
Ili ndi zotchingira zabwino komanso zoletsa kukalamba, ndipo imakhala ndi moyo wautali.Kupezeka kwa ulusi wa aramid kumaonedwa kuti ndi njira yofunika kwambiri ya mbiri yakale muzinthu zakuthupi.
Aramid CHIKWANGWANI ndi zida zofunika zankhondo pachitetezo cha dziko.Pofuna kukwaniritsa zosoŵa zankhondo zamakono, pakali pano, majekete oteteza zipolopolo a mayiko otukuka monga United States ndi United Kingdom amapangidwa ndi ulusi wa aramid.Kupepuka kwa ma jekete ndi zipewa za aramid fiber bulletproof kumathandizira kuti asitikali azitha kuchitapo kanthu mwachangu komanso kupha.Mu Nkhondo ya Gulf, ndege za ku America ndi ku France zinagwiritsa ntchito zida zambiri za aramid.Kuphatikiza pa ntchito zankhondo, monga zida zapamwamba zamakono zakhala zikugwiritsidwa ntchito kwambiri muzamlengalenga, makina ndi magetsi, zomangamanga, magalimoto, masewera ndi zinthu zina zachuma zadziko.Pankhani ya ndege ndi ndege, fiber ya aramid imapulumutsa mphamvu zambiri zamafuta chifukwa cha kulemera kwake komanso mphamvu zake zambiri.Malingana ndi deta yapadziko lonse, panthawi yotsegulira ndege, kuchepetsa kulemera kwa 1 kg kumatanthauza kuchepetsa ndalama za 1 miliyoni za US.Kuonjezera apo, chitukuko chofulumira cha sayansi ndi zamakono chikutsegulira malo atsopano a Aramid.Akuti pakali pano, pafupifupi 7 ~ 8% ya mankhwala aramid ntchito flak jekete, zipewa, ndi zina zotero, ndipo pafupifupi 40% ntchito zipangizo zakuthambo ndi zipangizo masewera.Zida zamafupa a matayala, lamba wonyamula katundu ndi zinthu zina za 20%, ndi chingwe champhamvu kwambiri ndi zina za 13%.
Mitundu ndi Ntchito za Aramid fiber: Para-Aramid fiber (PPTA) ndi interaromatic amide fiber (PMIA)
Pambuyo pakukula bwino komanso kutukuka kwa fiber aramid ndi DuPont m'zaka za m'ma 1960, pazaka zopitilira 30, ulusi wa aramid wadutsa njira yosinthira kuchoka ku zida zankhondo kupita kuzinthu za anthu wamba, ndipo mtengo wake wachepetsedwa ndi theka.Pakadali pano, ulusi wa aramid wakunja ukukhwima mu kafukufuku ndi chitukuko komanso kupanga masikelo.M'munda wa fiber aramid fiber, para aramide fiber ndiyo ikukula kwambiri, ndipo mphamvu yake yopanga imakhala ku Japan, United States ndi Europe.Mwachitsanzo, Kevlar wochokera ku dupont, ulusi wa Twaron wochokera ku Akzo Nobel (wophatikizidwa ndi Teren), ulusi wa Technora wochokera ku TeREN waku Japan, ulusi wa Terlon waku Russia, ndi zina zambiri.
Pali Nomex, Conex, Fenelon fiber ndi zina zotero.Dupont waku United States ndi mpainiya pakukula kwa aramid.Imakhala yoyamba padziko lapansi mosasamala kanthu za kafukufuku ndi chitukuko cha zinthu zatsopano, malamulo opangira ndi gawo la msika.Pakadali pano, ulusi wake wa Kevlar uli ndi mitundu yopitilira 10, monga Kevlar 1 49 ndi Kevlar 29, ndipo mtundu uliwonse uli ndi zambiri.Dupont adalengeza chaka chatha kuti ikulitsa mphamvu zake zopangira Kevlar, ndipo ntchito yokulitsa ikuyembekezeka kumalizidwa kumapeto kwa chaka chino.Osapitilira, mabizinesi odziwika bwino opanga ma aramid monga Di Ren ndi Hearst akulitsa kupanga kapena kugwirizanitsa, ndikufufuza msika mwachangu, ndikuyembekeza kukhala mphamvu yatsopano pantchito yotuluka dzuwa.
Kampani yaku Germany Acordis posachedwapa idapanga zinthu zamtundu wa ultrafine contrapuntal ron (Twaron), zomwe siziwotcha kapena kusungunuka, ndipo zimakhala ndi mphamvu yayikulu komanso kukana kwakukulu, zomwe zimagwiritsidwa ntchito popanga nsalu zokutira komanso zosakutidwa, zoluka ndi singano ndi zina zambiri. -kutentha ndi kukana kwa mitundu yonse ya nsalu ndi zovala.Ubwino wa silika woonda kwambiri wa Twaron ndi 60% yokha ya arylon ya counterpoint yomwe imagwiritsidwa ntchito popanga masuti otetezeka pantchito, ndipo imatha kugwiritsidwa ntchito kupanga magolovesi.Kutha kwake odana ndi kudula kumatha kusintha ndi 10%.Itha kugwiritsidwa ntchito popanga nsalu zoluka ndi zinthu zoluka, zokhala ndi manja ofewa komanso kugwiritsa ntchito bwino.Magolovesi odana ndi kudula a Twaron amagwiritsidwa ntchito makamaka m'makampani opanga magalimoto, makampani opanga magalasi komanso opanga zitsulo.Atha kugwiritsidwanso ntchito m'makampani opanga nkhalango kupanga zinthu zoteteza miyendo ndikupereka zida zothana ndi kuwonongeka kwamakampani onyamula anthu.
Katundu wozimitsa moto wa Twaron angagwiritsidwe ntchito popereka zida zozimitsa moto ndi ma suti oteteza komanso zofunda, komanso madipatimenti oyendetsa kutentha kwambiri monga kuponyera, ng'anjo, fakitale yamagalasi, ndi zina zambiri, komanso kupanga zida zotchingira moto zotchingira mipando yandege.Ulusi wapamwambawu ukhoza kugwiritsidwanso ntchito popanga matayala agalimoto, mapaipi oziziritsa, V-lamba ndi makina ena, zingwe za fiber optical ndi ma vests oteteza zipolopolo ndi zida zina zodzitetezera, komanso zimatha kulowa m'malo mwa asibesitosi ngati zida zokangana ndi zida zosindikizira.
Kufuna Msika
Malinga ndi ziwerengero, padziko lonse lapansi kufunikira kwa fiber aramid ndi matani 360,000 / chaka mu 2001, ndipo idzafika matani 500,000 / chaka mu 2005. Kufunika kwapadziko lonse kwa aramid fiber kukuwonjezeka nthawi zonse, ndi fiber aramid, monga chingwe chatsopano chapamwamba kwambiri. , walowa m'nthawi ya chitukuko chofulumira.
