I-Para-aramid PPTA FR Staple Fiber Pulp ye-Bulletproof Ballistic Armor efana ne-Kevlar, i-Twaron, i-Technora Fiber
I-Para-aramid fiber (PPTA) ye-Aopoly ikhiqizwa ubuchwepheshe bokuphotha bekristalu obuwuketshezi obusuka kuma-macromolecules afana nenduku eqinile (PPTA) eyenziwe nge-polymerized yi-terephthaloyl chloride (TCL) kanye ne-p-phenylenediamine (PPD) izixazululo.I-Para-aramid inezakhiwo ezingavamile zamandla aphezulu, i-modulus ephezulu, ukumelana nokushisa okuphezulu nokumelana namalangabi.Inezinzuzo zokuminyana okulinganiselwe okuphansi, ukumelana nokukhathala, ukumelana nezinyembezi nokugunda kanye nokuzinza kwe-dimention.Inhlanganisela yalezi zakhiwo eziyingqayizivele iholela i-para-aramid ukuthi ibe ifayibha yokusebenza okuphezulu ene-ourput enkulu kunazo zonke emhlabeni, imicu emithathu ephezulu esebenza kahle kanye “nocingo lokwenziwa”.Isetshenziselwa kakhulu ukuhlanganiswa kokusebenza okuphezulu, ukuvikelwa komuntu siqu, ukuxhumana nge-elekthronikhi, ezokuthutha nezinto ezisekela ukukhanya okukhulu, njll.
Izakhiwo Zomkhiqizo
◎ Amandla Aphezulu: Isilinganiso sesisindo/amandla izikhathi ezingu-5~6 zocingo lwensimbi, izikhathi ezi-3 zefayibha yengilazi kanye nezikhathi ezingu-2 zenayiloni enamandla amakhulu.
◎ I-Modulus Ephakeme: Isilinganiso sesisindo/imoduli izikhathi ezi-3 zocingo lwensimbi, izikhathi ezi-2 zefayibha yengilazi kanye nezikhathi ezingu-10 zenayiloni enamandla amakhulu.
◎ Ukumelana Nokushisa: Ayinakho ukubola noma ukuncibilika ku-500 ℃ futhi ingasetshenziswa ngokuqhubekayo ukusuka -196℃ kuya ku-204℃.Igcina amandla angu-95% ngemva kokuchayeka okungu-500hus ngaphansi kuka-160℃ futhi igcina amandla angu-75% ngemva kokuchayeka amahora angu-100 ngaphansi kuka-200℃.
Izicelo Eziyinhloko
I-Geotechnique & Strcture kakhonkolo: I-Para-aramid fiber isetshenziselwa ukulungisa umonakalo wesakhiwo sikakhonkolo.Imicu ye-Aramid isongwe ezinsikeni zikakhonkolo eziqinisiwe bese iqhubeka nokufaka i-resin impregnation kanye nokwelapha okusetshenziselwa ukulungisa izakhiwo ezindala nezilimele bese ukuqinisa isakhiwo (isibonelo, ukuhlangabezana nezidingo zokuvikela ukuzamazama komhlaba).
Izinto zokuqinisa: i-optic fiber nezintambo, imikhiqizo yamasondo nenjoloba, i-naan kawoyela ethambile, izinga lokushisa eliphezulu nepayipi lokumelana nokucindezela.
Imikhiqizo Yezinhlamvu: Isivikelo sokuphepha: ivesti/isigqoko esingangenwa izinhlamvu, izingubo ezivikela ama-arc, isambatho zempi esiyinhlanganisela esingasindi.
Imikhiqizo elwa nokusika: ezinqubweni ezivamile zezimboni, abasebenzi bavame ukuthinta imiphetho ebukhali noma izinto ezishisayo, okuhlanganisa ingilazi noma izingxenye zensimbi.Emisebenzini enjalo yezimboni, amagilavu okuzivikela ayadingeka ngokusobala.
Amagilavu okuphepha efayibha ye-Para-aramid ahlinzeka opharetha ngezinga elithile lobuciko, kodwa futhi ahlanganisa ngokuphelele ukuvikela okungcono kakhulu, ukunethezeka kanye nokusebenziseka kalula.I-Para-aramid ingaphinde inikeze ukuvikelwa kwemilenze kubasebenzi basehlathini, futhi ingasetshenziswa njengendwangu ekwazi ukumelana nomonakalo yezihlalo zamabhasi nezesitimela.
Izinto ezihlanganisiwe: izinto ezihlanganisiwe eziqinisiwe zinezidingo eziphezulu kakhulu zokubekezelela okungasindi kanye nokulimala, futhi imicu ye-para-aramid idlala indima ebalulekile kulokhu.I-Para-aramid izibophezele ekuhlinzekeni izixazululo zobuchwepheshe obuphezulu ezindaweni ezidinga izinto eziyinhlanganisela, okuhlanganisa ubunjiniyela basolwandle kanye ne-aerospace, ubunjiniyela bomphakathi, ezokuthutha ezihamba phansi, amapulasitiki obunjiniyela, amagobolondo emoto yemoto/yacht zemidlalo.
Izinto zokuhlanganisa nokuvala: Ukwengeza i-aramid pulp kanye nefayibha eqoshiwe kungathuthukisa ukusebenza kwamabhuleki amabhuleki, ama-brake pad linings, namapuleti e-clutch friction, ngaleyo ndlela kwandise impilo yomkhiqizo futhi kuthuthukise ukunethezeka kokushayela.
Ikakhulukazi mayelana nokunethezeka, i-pulp ye-aramid ibe negalelo elikhulu ekunciphiseni umsindo, ukudlidliza kanye nokhahlo (NVH).Kusekelwe kulezi zakhiwo eziyingqayizivele ukuthi i-aramid pulp isiphenduke into yokuzikhethela kubakhiqizi bemikhiqizo yokungqubuzana emhlabeni jikelele.Ngenxa yokuncishiswa kokungqubuzana kwama-brake pads, izidingo zokusebenza zezinto ezisetshenzisiwe ziyaqiniswa nakakhulu-ukusebenza okuhle kakhulu kwemikhiqizo ye-aramid fiber kudlala indima futhi lapha.
Imishini yezemidlalo nezinye: izintambo, izintambo ze-kite, amakilabhu egalofu, ama-sledges, njll.
