Para-aramid PPTA FR Staple Fiber Pulp ya Bulletproof Ballistic Armor yofanana ndi Kevlar, Twaron, Technora Fiber
Para-aramid CHIKWANGWANI (PPTA) wa Aopoly amapangidwa ndi madzi crystal kupota teknoloji kuchokera rigid ndodo-ngati macromolecules (PPTA) polymerized ndi terephthaloyl kolorayidi (TCL) ndi p-phenylenediamine (PPD) mayankho.Para-aramid ili ndi mphamvu zodabwitsa zamphamvu kwambiri, modulus yayikulu, kukana kutentha kwambiri komanso kukana moto.Ili ndi ubwino wocheperako wachibale, kukana kutopa, kukana kung'ambika ndi kukameta ubweya ndi kukhazikika kwapakati.Kuphatikizika kwa zinthu zapaderazi kumapangitsa kuti para-aramid ikhale ulusi wochita bwino kwambiri wokhala ndi zida zathu zazikulu kwambiri padziko lonse lapansi, zida zitatu zapamwamba zogwira ntchito kwambiri komanso "waya wopangira".Amagwiritsidwa ntchito kwambiri popanga zinthu zambiri, chitetezo chamunthu, kulumikizana ndi zamagetsi, mayendedwe ndi zida zowunikira kwambiri, ndi zina zambiri.
Zida Zamalonda
◎ Mphamvu Zazikulu: Chiŵerengero cha kulemera/mphamvu ndi 5 ~ 6 nthawi za waya wachitsulo, nthawi 3 za ulusi wagalasi ndi nthawi 2 za nayiloni yamphamvu kwambiri.
◎ High Modulus: Chiŵerengero cha kulemera/modulus ndi nthawi 3 za waya wachitsulo, 2 nthawi za ulusi wa galasi ndi nthawi 10 za nayiloni yamphamvu kwambiri.
◎ Kukana Kutentha: Kulibe kuwola kapena kusungunuka pa 500 ℃ ndipo kumatha kugwiritsidwa ntchito mosalekeza kuyambira -196 ℃ mpaka 204 ℃.Imasunga 95% mphamvu pambuyo pa 500hus kukhudzana ndi 160 ℃ ndipo imasunga 75% mphamvu pambuyo pa 100hrs kukhudzana pansi pa 200 ℃.
Main Applications
Geotechnique & kamangidwe konkire: Ulusi wa Para-aramid umagwiritsidwa ntchito kukonza zowonongeka kwa konkire.Ulusi wa Aramid umakulungidwa pamizati yolimba ya konkriti kenako ndikupitilira kuyika kwa utomoni ndikuchiritsa komwe kumagwiritsidwa ntchito kukonzanso zomanga zakale ndi zowonongeka kenako kulimbikitsanso kapangidwe kake (mwachitsanzo, kukwaniritsa zofunikira zachitetezo cha chivomezi).
Zipangizo zolimbikitsira: ulusi wa optic ndi zingwe, matayala ndi zinthu za raba, mafuta ofewa a naan, kutentha kwambiri komanso payipi yolimbana ndi kuthamanga.
Zopangira Zopanda Zipolopolo: Chitetezo chachitetezo: vest / chisoti chosalowerera zipolopolo, zovala zosaoneka ngati arc, zida zankhondo zopepuka.
Zotsutsana ndi kudula: m'mafakitale wamba, ogwira ntchito nthawi zambiri amagwira m'mbali zakuthwa kapena zinthu zotentha, kuphatikiza magalasi kapena zitsulo.Pazochita zamafakitale zotere, magolovesi oteteza mwachiwonekere ndi ofunikira.
Magolovesi otetezedwa a Para-aramid fiber amapatsa ogwiritsa ntchito kuchuluka kwaukadaulo, komanso amaphatikiza bwino chitetezo, chitonthozo komanso kugwiritsa ntchito mosavuta.Para-aramid ingaperekenso chitetezo cha miyendo kwa ogwira ntchito m'nkhalango, ndipo ingagwiritsidwenso ntchito ngati nsalu yotchinga kuwonongeka kwa mipando ya basi ndi sitima.
Zida zophatikizika: zida zophatikizika zolimba zimakhala ndi zofunika kwambiri pakulolera kopepuka komanso kuwonongeka, ndipo ulusi wa para-aramid umagwira ntchito yofunika kwambiri pa izi.Para-aramid yadzipereka kuti ipereke njira zaukadaulo zapamwamba kumadera omwe amafunikira zida zophatikizika, kuphatikiza uinjiniya wapanyanja ndi zakuthambo, zomangamanga, zoyendera pansi, mapulasitiki a engineering, zipolopolo zamagalimoto zamagalimoto / yacht katundu wamasewera.
Zipangizo zomangira ndi zosindikizira: Kuwonjezera ma aramid zamkati ndi ulusi wodulidwa kumatha kupititsa patsogolo magwiridwe antchito a ma brake pad, ma brake pad linings, ndi mbale zogundana ndi clutch, potero kumakulitsa moyo wazinthu ndikuwongolera kuyendetsa bwino.
Makamaka ponena za chitonthozo, zamkati za aramid zathandizira kwambiri kuchepetsa phokoso, kugwedezeka ndi nkhanza (NVH).Zimatengera zinthu zapaderazi zomwe zamkati za aramid zakhala zosankhika kwa opanga zinthu zokangana padziko lonse lapansi.Chifukwa cha kugunda kwapang'onopang'ono kwa ma brake pads, zofunikira pakugwira ntchito kwa zida zomwe zimagwiritsidwa ntchito zimalimbikitsidwanso-kuchita bwino kwa zinthu za aramid fiber kumagwiranso ntchito pano.
Zida zamasewera ndi zina: zingwe, zingwe za kite, makalabu a gofu, sileji, ndi zina.
