1.Gusobanura fibre ya aramid
Aramide fibre nizina rusange rya fibre ya aromatic polyamide.
2.Gushyiramo fibre ya aramid
Fibre ya Aramide ukurikije imiterere ya molekile irashobora kugabanywamo ubwoko butatu: fibre para-aromatic polyamide fibre, fibre inter-aromatic polyamide, fibre aromatic polyamide copolymer fibre. Muri byo, fibre ya para-aromatic polyamide igabanijwemo fibre poly-phenylamide (poly-p-aminobenzoyl), fibre poly-benzenedicarboxamide terephthalamide, fibre fibre hagati ya benzodicarbonyl terephthalamide igabanijwemo fibre poly-m-tolyl terephthalamide, poly-N Nm-tolyl-bis- (isobenzamide) fibre ya terephthalamide.
3.Ibiranga fibre ya aramid
1. Ibikoresho byiza bya mashini
Interposition aramid ni polymer yoroheje, kumeneka imbaraga zirenze polyester isanzwe, ipamba, nylon, nibindi, kurambura ni binini, byoroshye gukoraho, kuzunguruka neza, birashobora kubyara muburyo butandukanye, uburebure bwa fibre ngufi na filaments, muri rusange imyenda. imashini zikoze mubudodo butandukanye buboheye mubitambara, ibitambara bidoda, nyuma yo kurangiza, kugirango byuzuze ibisabwa mubice bitandukanye byimyambaro ikingira.
2. Umuriro mwiza cyane no kurwanya ubushyuhe
Indangagaciro ya ogisijeni igabanya (LOI) ya m-aramid ni 28, ntabwo rero ikomeza gutwika iyo ivuye mumuriro. Ikirimi cya flame retardant ya m-aramid igenwa nuburyo bwayo bwa chimique, bigatuma iba fibre retardant fibre idahoraho cyangwa idatakaza cyangwa itakaza flame retardant hamwe nigihe cyangwa gukaraba. M-aramid ihagaze neza kandi irashobora gukoreshwa ubudahwema kuri 205 ° C kandi ikomeza imbaraga nyinshi mubushyuhe burenze 205 ° C. M-aramid ifite ubushyuhe bwo kubora cyane kandi ntishonga cyangwa ngo itonywe ku bushyuhe bwo hejuru, ariko itangira kwaka ubushyuhe burenze 370 ° C.
3. Imiterere yimiti ihamye
Usibye acide zikomeye hamwe nifatizo, aramid mubyukuri ntaho ihuriye numuti wamavuta namavuta. Imbaraga zitose za aramid zingana hafi nimbaraga zumye. Ihungabana ryumwuka wamazi uruta iyindi fibre organic.
Aramide irasa cyane numucyo UV. Niba ihuye n'izuba igihe kirekire, itakaza imbaraga nyinshi bityo igomba gukingirwa nurwego rukingira. Uru rwego rwo kurinda rugomba gushobora guhagarika ibyangiritse kuri skeleti ya aramid kuva kumuri UV.
4. Kurwanya imirasire
Imirasire irwanya intera intera ni nziza cyane. Kurugero, munsi ya 1.72x108rad / s ya r-imirasire, imbaraga ziguma zihoraho.
5. Kuramba
Nyuma yo gukaraba 100, imbaraga zo kurira zimyenda ya m-aramid irashobora kugera hejuru ya 85% yimbaraga zumwimerere. Ubushyuhe bwo kurwanya para-aramide burenze ubw'imikoranire hagati ya aramide, hamwe no gukoresha ubushyuhe buri hagati ya -196 ° C kugeza kuri 204 ° C kandi nta kubora cyangwa gushonga kuri 560 ° C. Ikintu cyingenzi kiranga para-aramid nimbaraga zayo nyinshi na modulus yo hejuru, imbaraga zayo zirenga 25g / dan, ni inshuro 5 ~ 6 zicyuma cyiza cyane, inshuro 3 za fibre yikirahure ninshuro 2 zingufu za nylon inganda ; modulus yayo ni inshuro 2 ~ 3 zicyuma cyiza cyangwa fibre fibre hamwe ninshuro 10 zingufu nyinshi nylon inganda. Imiterere yihariye yubuso bwa aramid pulp, ibonwa na fibrillation yubuso bwa fibre ya aramide, itezimbere cyane gufata ifumbire bityo bikaba byiza nkibikoresho byongera imbaraga zo guterana no gufunga ibicuruzwa. Aramid Pulp Hexagonal Fibre idasanzwe I Aramid 1414 Pulp, flocculent yumuhondo yoroheje, plush, hamwe nibibyimba byinshi, imbaraga nyinshi, ituze ryiza, kutavunika, kwihanganira ubushyuhe bwinshi, kwihanganira ruswa, gukomera, kugabanuka gukabije, kurwanya abrasion nziza, ubuso bunini , guhuza neza nibindi bikoresho, ibikoresho bishimangira hamwe nubushuhe bwa 8%, uburebure bwa 2-2.5mm nubuso bwa 8m2 / g. Ikoreshwa nk'ibikoresho bishimangira gasike ifite imbaraga zo kwihangana no gukora neza, kandi ntabwo byangiza ubuzima bwabantu n’ibidukikije, kandi irashobora gukoreshwa mugushira ikimenyetso mumazi, amavuta, acide idasanzwe nimbaraga zo hagati hamwe nibitangazamakuru bya alkali. Byaragaragaye ko imbaraga zibicuruzwa zihwanye na 50-60% bya fibre ya asibesitosi fibre yongerewe imbaraga iyo hiyongereyeho munsi ya 10% ya slurry. Ikoreshwa mugushimangira guterana no gufunga ibikoresho nibindi bicuruzwa byakozwe, kandi irashobora gukoreshwa muburyo bwa asibesitosi kubikoresho bifunga kashe, impapuro zokoresha ubushyuhe bukabije kandi zishimangira ibikoresho.
