Izici zephepha le-aramid
Ukuzinza okushisayo okuhlala isikhathi eside. Isici esivelele kunazo zonke se-aramid 1313 ukumelana kwayo nokushisa okuphezulu, okungasetshenziswa isikhathi eside ekushiseni okuphezulu kwe-220 ℃ ngaphandle kokuguga. Izakhiwo zayo zikagesi nezemishini zingagcinwa iminyaka engaba ngu-10, futhi ukuzinza kwayo kobukhulu kuhle kakhulu. Cishe ku-250 ℃, izinga layo lokuncipha okushisayo liyi-1% kuphela; Ukuchayeka isikhathi esifushane emazingeni okushisa angu-300 ℃ angeke kubangele ukuncipha, ukufiphala, ukuthambisa, noma ukuncibilika; Iqala kuphela ukubola emazingeni okushisa angaphezu kwama-370 ℃; I-Carbonization iqala cishe ku-400 ℃ - ukuzinza okuphezulu kangaka kokushisa kuyivelakancane emiculweni yemvelo ekwazi ukumelana nokushisa.
Ukuncipha komlilo okuziqhenyayo. Iphesenti le-oxygen elidingekayo ukuze into ethile ivuthe emoyeni libizwa ngokuthi inkomba ye-oxygen ewumkhawulo, futhi uma iphakama inkomba ye-oksijini ewumkhawulo, kuba ngcono ukusebenza kwayo kwelangabi. Ngokuvamile, okuqukethwe kwe-oxygen emoyeni kungu-21%, kuyilapho umkhawulo we-oxygen index ye-aramid 1313 inkulu kunama-29%, okwenza kube i-fiber evimbela ilangabi. Ngakho-ke, ngeke ishise emoyeni noma lisize ekushiseni, futhi linezici zokuzicisha ngokwazo. Lesi sici esingokwemvelo esitholakala esakhiweni saso samangqamuzana senza i-aramid 1313 ibambezeleke unomphela ilangabi, yingakho yaziwa ngokuthi "i-fireproof fiber".
I-insulation kagesi enhle kakhulu. I-Aramid 1313 ine-dielectric engaguquki ephansi kakhulu futhi amandla ayo e-dielectric engokwemvelo ayenza ikwazi ukugcina ukufakwa kukagesi okuhle kakhulu ngaphansi kwezinga lokushisa eliphezulu, izinga lokushisa eliphansi, nezimo zomswakama ophezulu. Iphepha le-insulation elilungiswe ngayo lingamelana nokwehla kwamandla kagesi afinyelele ku-40KV/mm, okulenze libe yinto eyaziwa kakhulu emhlabeni wonke.
Ukuzinza kwamakhemikhali okuvelele. Ukwakheka kwamakhemikhali e-aramid 1313 kuzinze ngendlela engavamile, amelana nokugqwala kwama-asidi angaphilayo agxile kakhulu namanye amakhemikhali, futhi amelana ne-hydrolysis nokugqwala kwesitimu.
Izakhiwo ezinhle kakhulu zemishini. I-Aramid 1313 iyimpahla ye-polymer eguquguqukayo enokuqina okuphansi kanye nobude obuphakeme, obunikeza ukuphonswa okufanayo njengemicu evamile. Ingacutshungulwa ibe yizindwangu ezihlukahlukene noma izindwangu ezingalukiwe kusetshenziswa imishini yokuphotha evamile, futhi ayigugi futhi imelana nezinyembezi, enezinhlobonhlobo zezicelo.
Ukumelana nemisebe enamandla kakhulu. I-Aramid 1313 ukumelana α、β、χ Ukusebenza kwemisebe evela emisebeni nokukhanya kwe-ultraviolet kuhle kakhulu. Ukusebenzisa i-50Kv χ Ngemva kwamahora angu-100 emisebe, amandla e-fiber ahlala eku-73% wawo wangempela, kuyilapho i-polyester noma inayiloni isivele iphenduke impushana.
