1.Ibikoresho bya fibre fibre

Izina ryuzuye rya fibre ya aramid ni fibre ya aromatic polyamide.Numurongo wa polymer ugizwe nitsinda rya aromatic hamwe na amide matsinda.Ifite imiterere yubukanishi, imiterere yimiti ihamye, imiterere yubukanishi bwiza, ultra-high strength and modulus high., ubushyuhe bwo hejuru, aside na alkali birwanya, uburemere bworoshye, kwambara birwanya nibindi byiza byiza.Yakoreshejwe cyane mubice nkibikoresho birinda amasasu, icyogajuru, ubwubatsi nibikoresho bya elegitoroniki.

Nyamara, fibre ya aramid nayo ifite ibibi bibiri byingenzi

(1) Fibre ya Aramide ifite imbaraga zo kurwanya UV.Imirasire ya ultraviolet (urumuri rw'izuba) itera kwangirika kwa fibre ya aramide.Kubwibyo, birakenewe urwego rwo gukingira, rushobora kuba ikote cyangwa urwego rwibikoresho, kurugero, insanganyamatsiko ya aramid akenshi iba ifunze murwego rwo gukingira.

.Byongeye kandi, gukoresha ubwoko bumwebumwe bwa aramide bigabanya kwinjiza amazi yibigize iyo ihuye namazi, nka Kevlar 149 cyangwa Armos.

2.PE ibikoresho bya fibre

PE mubyukuri bivuga UHMW-PE, ikaba ifite uburemere bukabije bwa polyethylene.Nibikorwa bya fibre ikora cyane byakozwe muntangiriro ya 1980.Hamwe na fibre ya karubone na aramid, izwi nka fibre eshatu zikomeye zo mu rwego rwo hejuru ku isi muri iki gihe.Ifite ultra-high stabilite kandi biragoye cyane kuyitesha agaciro, itera umwanda ukabije wibidukikije.Ariko mubyukuri kubera iyi miterere irahinduka ibikoresho byiza byo gukora ibirwanisho byumubiri.Byongeye kandi, irwanya ubushyuhe buke, urumuri UV, namazi.

Mu rwego rwo gukumira amasasu yihuta, imikorere yamasasu ya fibre ya PE iri hejuru ya 30% ugereranije niyi aramid;mu rwego rwo gukumira amasasu yihuta, imikorere ya PE fibre inshuro 1.5 kugeza kuri 2 ya aramid.Birashobora kuvugwa ko ibitagenda neza bya fibre ya aramide byahindutse ibyiza bya fibre ya PE, kandi ibyiza bya fibre ya aramide byabaye byiza kuri fibre ya PE.Kubwibyo, ni inzira byanze bikunze PE fibre yo gusimbuza aramid murwego rwo kurinda.

Nibyo, PE fibre nayo ifite ibitagenda neza.Urwego rwubushyuhe bwarwo ruri munsi ya fibre aramid.Gukoresha ubushyuhe bwibicuruzwa birinda fibre biri muri 70 ° C (bishobora kuba byujuje ibyifuzo byumubiri wumuntu nibikoresho, ni ukuvuga ko ubushyuhe bwo kurwanya ubushyuhe bwa 55 ° C).Kurenga ubu bushyuhe, imikorere igabanuka vuba.Iyo ubushyuhe burenze 150 ° C, fibre ya PE izashonga, na fibre ya aramide Fibre irashobora gukomeza ibintu byiza birinda ibidukikije bya 200 ° C, kandi ntishonga cyangwa ngo ibore kuri 500 ° C;mugihe uhuye nubushyuhe bwo hejuru hejuru ya 900 ° C, izahita iba karubone kugirango ikore ubushyuhe.Ibi ntibiboneka mubicuruzwa birinda PE fibre kandi byahindutse ibyiza byihariye byibicuruzwa bya aramid.
