I-fiberproof fibre - isakhiwo se-aramid 1313.

I-Aramid 1313 yathuthukiswa ngempumelelo yi-DuPont e-United States, futhi ukukhiqizwa kwezimboni kwenziwa ngo-1967, futhi umkhiqizo wabhaliswa njenge-Nomex® (Nomex).Lena i-fiber ethambile, emhlophe, ezacile, e-fluffy futhi ecwebezelayo.Ukubukeka kwayo kuyafana nokwemicu yamakhemikhali evamile, kodwa “inemisebenzi engavamile” engavamile:
Ukuzinza okushisayo okuhlala isikhathi eside.
Isici esivelele kunazo zonke se-aramid 1313 ukumelana kwayo nokushisa okuphezulu, okungasetshenziswa isikhathi eside ku-220 ℃ ngaphandle kokuguga.Ukusebenza kwezakhiwo zayo zikagesi nezemishini kungagcinwa iminyaka eyi-10, futhi ukuzinza kwayo kobukhulu kuhle kakhulu.Izinga lokushwabana okushisayo okungaba ngu-1% liyi-1% kuphela, futhi ngeke linciphe, lincibilike, lithambe noma lincibilike lapho libhekene nezinga lokushisa eliphakeme elingu-300°C isikhathi esifushane., ukuzinza okuphezulu okunjalo kokushisa kuhlukile phakathi kwemicu yamanje yemvelo ekwazi ukumelana nokushisa.
Ukubaleka kwamalangabi okuvelele.
Siyazi ukuthi iphesenti levolumu ye-oxygen edingekayo ukuze into ethile ishise emoyeni ibizwa ngokuthi inkomba ye-oxygen ekhawulelayo.Uma inkomba ye-oksijini ekhawulelayo iba nkulu, yenza ngcono ukusebenza kwayo kokunciphisa amalangabi.Ngokuvamile, okuqukethwe kwe-oxygen emoyeni kungu-21%, futhi inkomba ye-oxygen ekhawulelwe ye-aramid 1313 inkulu kune-28%.Lesi sici esingokwemvelo esitholakala esakhiweni sayo samangqamuzana senza i-aramid 1313 ibambezeleke unomphela ilangabi, ngakho inedumela “lefiber engashi”.
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.I-㎜, ibonwa njengento engcono kakhulu yokuvikela i-insulating emhlabeni.
Ukuzinza kwamakhemikhali okuvelele.
I-Aramid 1313 iyi-macromolecule eqondile eyakhiwe ngamabhondi e-amide axhuma amaqembu e-aryl.Ku-crystal yayo, izibopho ze-hydrogen zihlelwe ngezindiza ezimbili ukuze zakhe isakhiwo esinezinhlangothi ezintathu.Le bhondi ye-hydrogen eqinile yenza ukwakheka kwayo kwamakhemikhali kuzinze ngokwedlulele futhi Ikwazi Ukumelana nama-asidi angaphili agxile kakhulu namanye amakhemikhali, i-hydrolysis kanye nokugqwala kwesitimu.
Izakhiwo ezinhle kakhulu zemishini.
I-Aramid 1313 iyimpahla ye-polymer eguquguqukayo enokuqina okuphansi kanye nobude obuphakeme, okuyenza ikwazi ukuphenduka okufanayo njengemicu evamile.Ingacutshungulwa ibe yizindwangu ezihlukahlukene noma izindwangu ezingalukiwe ngemishini evamile yokuphotha, futhi ayigugi futhi ayizwani nokukhala.ebanzi kakhulu.
Ukumelana nemisebe ephezulu.
I-Aramid 1313 inokumelana okuhle kakhulu nemisebe ye-α, β, χ kanye nemisebe ye-ultraviolet.Ngemisebe ye-X-ray engu-50Kv amahora angu-100, amandla e-fiber ahlala e-73% yasekuqaleni, futhi i-polyester noma inayiloni ngalesi sikhathi isivele isiyimpushana.Isakhiwo samakhemikhali esiyingqayizivele nesizinzile sinikeza i-aramid 1313 ngezakhiwo ezinhle kakhulu.Ngokusetshenziswa okuphelele kwalezi zakhiwo, uchungechunge lwemisebenzi emisha nemikhiqizo emisha kuthuthukiswa ngokuqhubekayo, futhi izinkambu zohlelo lokusebenza ziya ngokuya ziba banzi, futhi ukuthandwa kuya ngokuya kukhula.
Izingubo zokuzivikela ezikhethekile.
Indwangu ye-Aramid 1313 ayishi, ayiconsi, incibilike futhi intuthu lapho ihlangana nomlilo, futhi inomphumela omuhle kakhulu wokuvikela umlilo.Ikakhulukazi lapho uhlangabezana nezinga lokushisa eliphakeme elingu-900-1500 ℃, indawo engaphezulu yendwangu izokwenziwa i-carbonized ngokushesha futhi ishube, yakhe umgoqo ohlukile wokuvikela ukushisa ukuze uvikele oyigqokile ekubalekeni.Uma inani elincane le-antistatic fiber noma i-aramid 1414 yengeziwe, ingavimbela ngokuphumelelayo indwangu ekuqhumeni futhi igweme izingozi ze-lightning arc, i-arc kagesi, ugesi omile, ilangabi nokunye.I-Aramid 1313 imicu engeyona i-ferrous ingasetshenziswa ukwenza izingubo ezihlukahlukene zokuzivikela ezikhethekile njengamasudi endiza, amasudi okulwa namakhemikhali, amasudi okulwa nomlilo, ama-ovaroli esithandweni, ama-ovaroli okushisela kagesi, amasudi alinganisa ingcindezi, ama-ovaroli angangeni emisebeni, amasudi okuvikela amakhemikhali, high-voltage shielding amasudi, njll Aviation, Aerospace, iyunifomu yezempi, ukuvikelwa umlilo, petrochemical, ugesi, igesi, metallurgy, racing kanye nezinye izinkambu eziningi.Ngaphezu kwalokho, emazweni athuthukile, izindwangu ze-aramid zibuye zisetshenziswe kabanzi njengendwangu yasehhotela, amaphaseji okusindisa ukuphila, imihlobiso yasendlini engashi, izembozo zebhodi loku-ayina, amagilavu ​​asekhishini, namaphijama abamba ilangabi ukuze kuvikelwe abantu abadala nezingane.
Izinto zokuhlunga izinga lokushisa eliphezulu.
Ukumelana nokushisa okuphezulu, ukuzinza kwe-dimensional kanye nokumelana kwamakhemikhali kwe-aramid 1313 kuyenza ibe namandla emkhakheni wokuhlunga kwezinga lokushisa eliphezulu.Imithombo yokuhlunga ye-Aramid isetshenziswa kakhulu ezitshalweni zamakhemikhali, izitshalo zamandla ashisayo, izitshalo ze-carbon black, izitshalo zikasimende, izitshalo ze-lime, izitshalo ze-coking, izincibilikisi, izitshalo ze-asphalt, izitshalo zepende, kanye namapayipi ashisa kakhulu nomoya oshisayo ezithandweni zikagesi ze-arc, ama-boilers kawoyela, nama-incinerators Ukuhlunga akukwazi nje ukususa uthuli ngokuphumelelayo, kodwa futhi ukumelana nokuhlasela kwamakhemikhali kwentuthu eyingozi, futhi ngesikhathi esifanayo kusiza ukubuyiswa kwezinsimbi eziyigugu.
Izinto zokwakha izinyosi.
Iphepha lesakhiwo se-Aramid 1313 lingasetshenziswa ukwenza ibhodi lesakhiwo sezinyosi esinezingqimba eziningi ze-biomimetic, elinamandla / isisindo esivelele kanye nesilinganiso sokuqina / isisindo (cishe izikhathi ezingu-9 kunensimbi), isisindo esilula, ukumelana nomthelela, ukumelana nelangabi, ukwahlukanisa, kanye nokuqina.Inezici zokumelana nokugqwala, ukumelana nokuguga kanye nokungena kahle kwamagagasi kagesi.Ilungele ukukhiqizwa kwezinto ezidlulisa amagagasi e-Broadband kanye nezingxenye ezinkulu zesakhiwo sokucindezeleka kwesibili eziqinile ezindizeni, imicibisholo namasathelayithi (njengamaphiko, ama-fairing, ama-cabin linings, iminyango, njll.).Iphansi, indawo yokubamba impahla kanye nodonga lokuhlukanisa, njll.), futhi ilungele ukukhiqizwa kwezikebhe, izikebhe zomjaho, izitimela ezihamba ngesivinini esikhulu nezinye izakhiwo zamasemishi ezisebenza kahle.
