Ibintu bitanu biranga fibre ya aramid
Umwenda wa Aramide, aribyo imyenda ya Kevlar, umwenda wa fibre ya aramid, umwenda wa aramide, ni ubwoko bwimyenda hamwe no kubika ubushyuhe.Ifite uburyo butandukanye bwo gusaba mu nganda no kurinda igisirikare.Ifite ibintu by'ingenzi bikurikira:
1. Ibikoresho byiza bya Aramide ni polymer yoroheje ifite imbaraga zo kumeneka kurenza polyester isanzwe, ipamba, nylon, nibindi, hamwe no kuramba cyane, kumva byoroshye no kuzunguruka neza, kandi birashobora gukorwa mumibabi yibyingenzi itandukanye.Mu mashini isanzwe yimyenda, fibre na filaments bikozwe mubudodo butandukanye hanyuma bikozwe mubitambara no mubudodo.Nyuma yo kurangiza, irashobora kuzuza ibisabwa byimyenda ikingira mubice bitandukanye.
2.Umuriro mwiza cyane wo kwirinda no kurwanya ubushyuhe.Meta-aramide ifite indangagaciro ya ogisijeni igabanya (LOI) irenga 28 bityo ntukomeze gutwika iyo uvuye mumuriro.Imikorere ya flame retardant ya Newstar® meta-aramid biterwa nimiterere yacyo ya chimique, bityo rero ni fibre retardant fibre ihoraho itazagabanya cyangwa gutakaza imitungo yayo ya retardant kubera gukoresha igihe no gukaraba.Newstar® meta-aramid ifite ubushyuhe bwiza, irashobora gukoreshwa ubudahwema kuri 205 ° C, kandi irashobora gukomeza imbaraga nyinshi mubushyuhe bwo hejuru hejuru ya 205 ° C.Newstar® meta-aramid ifite ubushyuhe bwangirika kandi ntibuzashonga cyangwa gushonga.Gushonga mugihe cy'ubushyuhe bwo hejuru.Carbonisation itangirira gusa ku bushyuhe buri hejuru ya 370 ° C.
3.Imiterere yimiti ihamye meta-aramide ifite imbaraga zo kurwanya imiti myinshi, irashobora kurwanya aside irike cyane, kandi ikagira alkali nziza mubushyuhe bwicyumba.
4. Imirasire irwanya meta-aramid ifite imishwarara idasanzwe.Kurugero, mugihe kirekire cyerekanwa na 1.2 × 10-2 w / in2 imirasire ya ultraviolet na 1.72 × 108rads imirasire ya gamma, ubukana bwabwo ntibuhinduka.
5. Kuramba meta-aramid itanga guterana neza hamwe no kurwanya imiti.Nyuma yo gukaraba 100, imbaraga zamarira yimyenda ivurwa hamwe na Newstar® meta-aramid irashobora kugera kuri 85% byimbaraga zumwimerere.
