I-Aramid 1313 yaqala ukuphuhliswa ngempumelelo yiDuPont e-United States, kwaye imveliso yoshishino yafunyanwa kwi-1967, kwaye imveliso yabhaliswa njengeNomex® (Nomex).Olu lucwecwe oluthambileyo, olumhlophe, olubhityileyo, oluthambileyo nolukhazimlayo.Inkangeleko yayo iyafana neyemicu yekhemikhali eqhelekileyo, kodwa “inemisebenzi engaqhelekanga” engaqhelekanga:
Uzinzo lwe-thermal oluzinzileyo.
Eyona nto ibalaseleyo ye-aramid 1313 kukumelana nobushushu obuphezulu, obunokusetyenziswa ixesha elide kwi-220℃ ngaphandle kokuguga.Ukusebenza kweempawu zayo zombane kunye noomatshini kunokugcinwa iminyaka eyi-10, kwaye ukuzinza kwayo kwe-dimensional kugqwesileyo.Izinga lokunciphisa i-thermal malunga ne-1% kuphela yi-1%, kwaye ayiyi kuncipha, i-embrittle, ithambe okanye inyibilike xa ibonakaliswe kubushushu obuphezulu be-300 ° C ixesha elifutshane., uzinzo olunjalo oluphezulu lwe-thermal luyingqayizivele phakathi kwe-organic organic-resistant fibers.
Okugqwesileyo kokuphela komlilo.
Siyazi ukuba ipesenti yomthamo we-oksijini efunekayo kwisixhobo sokutshisa emoyeni ibizwa ngokuba yi-indexing oxygen index.Ubukhulu besalathiso se-oksijini esithintelwayo, ngcono ukusebenza kwayo kwedangatye.Ngokuqhelekileyo, umxholo we-oksijeni emoyeni ngu-21%, kwaye i-oxygen indexing index ye-aramid 1313 inkulu kune-28%.Olu phawu lwendalo luvela kwisakhiwo sayo se-molecular senza i-aramid 1313 inqande umlilo ngokusisigxina, ngoko ke inegama elithi "fireproof fiber".
Ukufakelwa kombane okugqwesileyo.
I-Aramid 1313 ine-dielectric engaguqukiyo ephantsi kakhulu, kwaye amandla ayo e-dielectric engokwemvelo ayenza ikwazi ukugcina ubushushu bombane obugqwesileyo phantsi kobushushu obuphezulu, ubushushu obuphantsi, kunye neemeko zokufuma okuphezulu.㎜, yamkelwa njengeyona mathiriyeli ibalaseleyo emhlabeni.
Uzinzo olugqwesileyo lweekhemikhali.
I-Aramid 1313 yimacromolecule yomgca ehlanganiswe ngamabhondi e-amide adibanisa amaqela e-aryl.Kwikristale yayo, iibhondi ze-hydrogen zicwangciswe kwiinqwelomoya ezimbini ukwenza ulwakhiwo olunemigangatho emithathu.Le bhondi ye-hydrogen eyomeleleyo yenza ubume bayo beekhemikhali izinze kakhulu kwaye inokumelana neyona asidi i-inorganic egxininiswe kakhulu kunye nezinye iikhemikhali, i-hydrolysis kunye ne-steam corrosion.
Iimpawu ezigqwesileyo zoomatshini.
I-Aramid 1313 yinto eguquguqukayo yepolymer kunye nokuqina okuphantsi kunye nobude obuphezulu, okwenza kube yinto efanayo yokujikeleza njengemicu eqhelekileyo.Inokucutshungulwa ibe ngamalaphu ahlukeneyo okanye amalaphu angalukwanga ngoomatshini besiqhelo abasontayo, kwaye ayigugi kwaye ixhathisa ukukrazuka.ebanzi kakhulu.
Ukumelana nemitha ephezulu.
I-Aramid 1313 inokumelana okugqwesileyo kwi-α, β, χ imitha kunye nemitha ye-ultraviolet.Ngemitha ye-X-ray ye-50Kv kwiiyure ze-100, amandla e-fiber ahlala e-73% ye-original, kwaye i-polyester okanye i-nylon ngeli xesha sele ibe ngumgubo.Isakhiwo sekhemikhali esiyingqayizivele nesizinzileyo sinikezela i-aramid 1313 ngeempawu ezibalaseleyo.Ngokusetyenziswa okubanzi kwezi zakhiwo, uthotho lwemisebenzi emitsha kunye neemveliso ezintsha ziphuhliswa ngokuqhubekayo, kwaye imimandla yesicelo iya isanda kwaye ibanzi, kwaye ukuthandwa kuya kunyuka nangaphezulu.
Impahla ekhethekileyo yokukhusela.
Ilaphu le-Aramid 1313 alitshi, livuze, linyibilike kwaye liqhume xa lidibana nomlilo, kwaye linesiphumo esihle kakhulu sokumelana nomlilo.Ngokukodwa xa udibana nobushushu obuphezulu be-900-1500 ℃, umphezulu welaphu uya kwenziwa ngokukhawuleza ikharbhoni kwaye ujiye, yenze umqobo wokugquma we-thermal okhethekileyo ukukhusela lowo ulinxibileyo ekubalekeni.Ukuba inani elincinci le-antistatic fiber okanye i-aramid 1414 yongezwa, inokuthintela ngokufanelekileyo ilaphu ekuqhumeni kwaye igweme iingozi ze-arc yombane, i-arc yombane, umbane ongatshintshiyo, ilangatye kunye nokunye.I-Aramid 1313 i-fibers non-ferrous fibers ingasetyenziselwa ukwenza iimpahla ezahlukeneyo zokukhusela ezikhethekileyo ezifana neesuti zokubhabha, iisuti zokulwa nobungqina bekhemikhali, iisuti zokulwa nomlilo, i-ovaroli yesithando somlilo, i-ovaroli ye-welding yombane, iisuti zokulinganisa uxinzelelo, ii-ovaroli zobungqina bemitha, iisuti zokukhusela iikhemikhali, iisuti yokhuselo-voltage eliphezulu, etc. Aviation, aerospace, iyunifomu zomkhosi, ukhuseleko umlilo, petrochemical, zombane, igesi, metallurgy, racing kunye nezinye iinkalo ezininzi.Ukongeza, kumazwe ahambele phambili kwezoqoqosho, amalaphu e-aramid asetyenziswa ngokubanzi njengamalaphu ehotele, iipaseji ezisindisa ubomi, imihombiso yasekhaya engatshiyo, i-ayina ibhodi yokuayina, iiglavu zasekhitshini, kunye neepyjama ezingadangayo ukukhusela abantu abadala nabantwana.
Izinto zokucoca ubushushu obuphezulu.
Ukumelana nobushushu obuphezulu, ukuzinza komgangatho kunye nokumelana neekhemikhali ze-aramid 1313 kuyenza ibe yeyona nto iphambili kwintsimi yokucoca ubushushu obuphezulu.Imithombo yeendaba yokucoca i-Aramid isetyenziswa kakhulu kwizityalo zamachiza, izityalo zamandla ashushu, izityalo ezimnyama zekhabhoni, izityalo zesamente, izityalo ze-lime, izityalo ze-coking, izinyibilikisi, izityalo ze-asphalt, izityalo zepeyinti, kunye nobushushu obuphezulu kunye nomoya oshushu kwii-arc zombane, iibhoyila oyile, kunye incinerators Filtration ayikwazi kuphela ngokufanelekileyo ukususa uthuli, kodwa ukuxhathisa uhlaselo imichiza imisi eyingozi, kwaye kwangaxeshanye kube lula ukubuyiswa kweentsimbi ezixabisekileyo.
Izinto zokwakha i-Honeycomb.
Iphepha le-Aramid 1313 linokusetyenziswa ukwenza ibhodi yesakhiwo se-biomimetic ye-honeycomb ye-biomimetic eninzi, enegunya elibalaseleyo / umlinganiselo wobunzima kunye nokuqina / ubunzima bomlinganiselo (malunga namaxesha angama-9 entsimbi), ubunzima obulula, ukuxhathisa impembelelo, ukumelana nomlilo, ukugquma, kunye nokuqina.Ineempawu zokuxhathisa umhlwa, ukuxhathisa ukwaluphala kunye nokufikeleleka kakuhle kwamaza ombane.Ilungele ukuveliswa kwezixhobo zokuhambisa amaza e-broadband kunye namacandelo amakhulu oxinzelelo lwesibini oluqinileyo kwinqwelomoya, imijukujelwa kunye neesathelayithi (ezinje ngamaphiko, iifairings, iicabin linings, iingcango, njl.njl.).Umgangatho, ukubamba imithwalo kunye nodonga lokwahlula, njl.njl.), ikwalungele ukuveliswa kweeyachts, izikhephe zomdyarho, izitimela ezihamba ngesantya esiphezulu kunye nezinye izakhiwo zesandwich ezisebenza kakhulu.
