Magic aramid fibre

Fibre ya Aramide yavutse mu mpera za 1960.Byabanje kutamenyekana nkibikoresho byiterambere ryisi nibintu byingenzi byingenzi.Nyuma y’Intambara y'ubutita irangiye, fibre ya aramid, nk'ibikoresho bya tekinoroji yo mu rwego rwo hejuru, yakoreshejwe cyane mu nzego za gisivili, maze buhoro buhoro bimenyekana.Hariho ubwoko bubiri bwa fibre ya aramid ifite agaciro gakomeye: imwe ni meta-aramid fibre hamwe na zigzag molekulari itondekanya, ibyo bita fibre aramid 1313 mubushinwa;Imwe muriyo ni para-aramid fibre ifite umurongo wa molekuline itondekanya, bita fibre aramid 1414 mubushinwa.

Kugeza ubu, aramid fibre ni ikintu cyingenzi mu kurinda igihugu n’inganda za gisirikare.Mu rwego rwo guhaza ibikenewe mu ntambara zigezweho, amakoti y’amasasu y’ibihugu byateye imbere nka Amerika n’Ubwongereza akozwe muri fibre ya aramid.Uburemere bwimyambaro yamasasu yamasasu hamwe ningofero byazamuye neza ubushobozi bwihuse bwihuse nubwicanyi bwingabo.Mu ntambara yo mu kigobe, ibikoresho bya aramid byakoreshwaga cyane n'indege z'Abanyamerika n'Ubufaransa.Usibye gukoreshwa mu gisirikare, yakoreshejwe cyane nk'ibikoresho bya tekinoroji yo mu rwego rwo hejuru mu kirere, mu mashanyarazi, mu bwubatsi, mu modoka, ibicuruzwa bya siporo n'ibindi bijyanye n'ubukungu bw'igihugu.Mu ndege no mu kirere, fibre aramid ibika lisansi nyinshi kubera uburemere bwayo nimbaraga nyinshi.Dukurikije amakuru y’amahanga, buri kilo cyo kugabanya ibiro mugihe cyo kohereza icyogajuru bivuze kugabanya igiciro cya miliyoni imwe.Mubyongeyeho, iterambere ryihuse ryubumenyi nikoranabuhanga ririmo gufungura umwanya mushya wa gisivili ya aramid fibre.Nk’uko raporo zibitangaza, ibicuruzwa bya aramide bikoreshwa mu ikoti ridafite amasasu n'ingofero, bingana na 7-8%, naho ibikoresho byo mu kirere n'ibikoresho bya siporo bigera kuri 40%.Ibikoresho bya skeleton, ibikoresho byumukandara hamwe nibindi bice bingana na 20%, naho imigozi ikomeye cyane igera kuri 13%.Inganda zipine nazo zatangiye gukoresha umugozi wa aramid kubwinshi kugirango ugabanye uburemere no kurwanya.

Aramide, izwi cyane nka "polyphenylphthalamide" kandi yitwa Aramid fibre mucyongereza, ni ubwoko bushya bwa fibre ya tekinoroji yo mu rwego rwo hejuru, ifite ibintu byiza cyane nka ultra-high strength, modulus high, resistance ubushyuhe bwinshi, aside na anti-alkali, uburemere bworoshye, insulation, ubuzima burebure bwo kurwanya gusaza, nibindi. Imbaraga zayo zirenze 28g / denier, zikubye inshuro 5-6 iy'icyuma cyiza cyo mu rwego rwo hejuru, inshuro 2 z'icyuma gikomeye cya nylon, inshuro 1,6 ya grafite-imbaraga nyinshi cyane ninshuro 3 zi fibre.Modulus ikubye inshuro 2-3 iy'icyuma cyangwa fibre y'ibirahure, ubukomere bwikubye inshuro 2 ubw'icyuma, kandi uburemere ni hafi 1/5 cy'icyuma.Kurwanya ubushyuhe buhebuje, gukoresha igihe kirekire ubushyuhe bwa dogere 300, ubushyuhe bwigihe gito bwo hejuru ya dogere 586.Ivumburwa rya aramid fibre ifatwa nkigikorwa cyingenzi cyamateka murwego rwibikoresho.
