Ukusetshenziswa kwendwangu ye-aramid fiber emikhiqizweni engangenwa yizinhlamvu

I-Aramid fiberiyi-fiber yokwenziwa esebenza kahle kakhulu, enamandla aphezulu kakhulu, i-modulus ephezulu, ukumelana nokushisa okuphezulu, ukumelana ne-asidi ne-alkali, elula, nezinye izici ezinhle kakhulu. Amandla ayo angaba izikhathi ezi-5-6 kunezintambo zensimbi, i-modulus iphindwe izikhathi ezi-2-3 kunezintambo zensimbi noma i-fiber yengilazi, ukuqina kuphindwe izikhathi ezi-2 kunezintambo zensimbi, kanti isisindo singu-1/5 kuphela kunezintambo zensimbi. Ezingeni lokushisa eliphakeme elingu-560 ℃, imicu ye-aramid ingahlala izinzile, ingaboli, futhi ingancibiliki. Ngaphezu kwalokho, inezakhiwo ezinhle zokuvikela nokuvimbela ukuguga, kanye nokuphila isikhathi eside kwenkonzo. Njengamanje, imishini evamile yokuvikela izinhlamvu (njengezigqoko zokuvikela izinhlamvu, nezigqoko zokuvikela izinhlamvu) ivame ukusetshenziswa.izindwangu zefayibha ye-aramidPhakathi kwazo, indwangu engenalutho ye-aramid fiber ephansi ingomunye wezinto eziyinhloko emkhakheni wokuvikela izinhlamvu. Uma kuqhathaniswa nezikibha zangaphansi ze-nylon zendabuko nezigqoko zensimbi, izikibha zangaphansi ze-bulletproof nezigqoko ezinezintambo ze-aramid ezengeziwe azigcini nje ngokuba zincane futhi zilula kodwa futhi zisebenza kahle ngo-40% ngokumelene nezinhlamvu.

Isimiso sokusebenza samavesti angenazo izinhlamvu singaqondwa ngale ndlela: lapho inhlamvu ishaya ungqimba lwendwangu yevesti, amagagasi okushaqeka kanye nokucindezeleka akhiqizwa eduze nendawo yokushaya. Lawa magagasi adlula ekusabalaleni okusheshayo nasekusabalaleni kwe-fiber, angahamba ngenani elikhulu lezintambo, bese efika endaweni enkulu ukuze amunce amandla e-shock wave. Yilokhu kumuncwa kwamandla okubanzi okunciphisa ngempumelelo umthelela wezinhlamvu emzimbeni womuntu, ngaleyo ndlela kuqaphele umphumela wokuvikela wamavesti angenazo izinhlamvu.

Izinto ezingangenwa yizinhlamvu kanye nokusebenza kwazo okuhle kakhulu

Ingqikithi yamavesti angenazinhlamvu isezintweni zefayibha ezinamandla aphezulu abazisebenzisayo, lapho imicu ye-para-aramid, eyaziwa nangokuthi imicu ye-polyamide ye-para-aromatic, iyinto ehlonishwa kakhulu engangenisi nhlamvu. Isakhiwo sayo samakhemikhali esilinganayo kakhulu sinikeza uchungechunge lwama-molecule ukuqina okuhle kakhulu, okwenza luhluke kakhulu kuma-polymer avamile aguquguqukayo ngokwezinto ezincibilikayo, izakhiwo ze-rheological, kanye nokucubungula.

Imicu ye-Para-aramid yaziwa ngezakhiwo zayo ezinhle kakhulu zomzimba nezemishini, okuhlanganisa amandla aphezulu kakhulu, i-modulus ephezulu, kanye nokukhanya okulula. Amandla ayo athile aphezulu ngokuphindwe kahlanu kuya kweziyisithupha kunowensimbi yensimbi evamile, futhi i-modulus yayo ethile idlula eyensimbi ngesilinganiso esiphindwe kabili kuya kwesithathu. Ngaphezu kwalokho, imicu ibonisa izakhiwo ezinhle kakhulu zokushisa, ngokumelana nokushisa okuphezulu, ukwanda okuphansi, kanye nokuqhuba kokushisa okuphansi, futhi ayishisi noma incibilike. Imicu ye-Para-aramid yaziwa nangokuthi “imicu yezinhlamvu” ngenxa yokuvikela kwayo okuhle, ukumelana nokugqwala, kanye nokumelana nokuguga.

Izicelo kanye namathemba e-Para-I-Aramid Fiber

I-Para-aramid fiber, into ebalulekile embonini yezokuvikela neyezempi, isetshenziswa kabanzi emhlabeni wonke. Ngokwezibalo, isilinganiso se-aramid kuma-faibha okuvikela e-US singaphezu kuka-50% no-10% eJapane. Izici zayo ezilula zenza amavesti nezigqoko ze-aramid ezingangeni zinhlamvu, okungathuthukisa kakhulu amandla okuphendula ngokushesha kwebutho. Ngaphezu kwalokho, i-para-aramid isetshenziswa kabanzi kwezimoto, ezokuxhumana, ezindizayo, kanye nemidlalo yangaphandle ngenxa yokusebenza kwayo okuhle kakhulu.
