Fibre ya UHMWPE ifite ibintu byinshi byiza cyane, nkibikoresho byiza bya mashini, birwanya ingaruka nziza, birwanya kwambara neza, kurwanya ruswa, kurwanya urumuri rwiza nibindi.
1. Ibikoresho byiza bya mehaniki ya UHMWPE fibre.
UHMWPE fibre ifite imiterere myiza yubukanishi. Munsi yubucucike bumwe, imbaraga zingana za fibre ya UHMWPE yikubye inshuro 15 umugozi wicyuma. Irenze 40% kurenza fibre ya aramide, nayo ikaba imwe muma fibre atatu yubuhanga buhanitse kwisi, kandi ikubye inshuro 10 kurenza ibyuma byujuje ubuziranenge hamwe na fibre isanzwe. Ugereranije nicyuma, E-ikirahure, nylon, polyamine, fibre karubone na fibre ya boron, imbaraga zayo na modulus biruta ibyo muri fibre, kandi imbaraga zayo nizo ziri hejuru mubikoresho bifite ubuziranenge bumwe.
2.Ingaruka zidasanzwe zo kurwanya fibre ya UHMWPE
Ultra muremure ya polyethylene fibre ifite imbaraga zo kurwanya ingaruka nziza. Ubushobozi bwayo bwo gukurura ingufu no kurwanya ingaruka mugihe cyo guhindura no kubumba birenze ibyo bya fibre aramid na fibre karubone, ari nabwo "fibre eshatu zo mu rwego rwo hejuru ku isi". Ugereranije na polyamide, aramide, E fibre yikirahure, fibre karubone na fibre aramide, fibre ya UHMWPE ifite imbaraga nyinshi zo kwinjiza kuruta ingaruka.
3. Kurwanya kwambara neza bya fibre ya UHMWPE
Muri rusange, uko modulus nini yibikoresho, niko bigabanya kwambara, ariko kuri fibre ya UHMWPE, ibinyuranye nukuri. Kuberako fibre ya UHMWPE ifite coefficient yo hasi yo guterana, nini modulus, niko irwanya kwambara. Ugereranije coefficente ya friction ya fibre ya UHMWPE hamwe na fibre ya karubone na fibre ya aramide, kwihanganira kwambara no kunanirwa kunanirwa kwa fibre UHMWPE birarenze cyane ibya fibre karubone na fibre ya aramide. Kurwanya kwayo rero birutwa nizindi fibre ikora cyane. Kubera uburyo bwiza bwo kwambara no kurwanya kunama, imikorere yayo yo gutunganya nayo irarenze, kandi biroroshye gukorwa mubindi bikoresho hamwe nigitambara.
4.Imiti ya ruswa irwanya fibre ya UHMWPE
Imiterere yimiti ya fibre ya UHMWPE iroroshye kandi imiterere yimiti irahagaze neza. Byongeye kandi, ifite icyerekezo cyimiterere ya kristaline cyane, ituma idashobora kwibasirwa nigitero cya genes ikora muri acide ikomeye kandi ikomeye, kandi irashobora kugumana imiterere yumwimerere nimiterere. Kubwibyo, ibintu byinshi byimiti ntabwo byoroshye kubora. Gusa ibisubizo kama kama birashobora kubyimba gato, kandi gutakaza imitungo yubukanishi ntibiri munsi ya 10%. Kugumana imbaraga za fibre ya UHMWPE na fibre ya aramid mubitangazamakuru bitandukanye bya chimique byagereranijwe. Kurwanya ruswa ya fibre ya UHMWPE biragaragara ko iruta iyo fibre ya aramid. Irahagaze neza cyane muri aside, alkali n'umunyu, kandi imbaraga zayo zabuze gusa mumuti wa sodium hypochlorite.
5.Urumuri rwiza cyane rwa fibre ya UHMWPE
Kuberako imiterere yimiti ya fibre ya UHMWPE itajegajega, irwanya urumuri narwo rwiza muri fibre yubuhanga buhanitse. Fibre ya Aramide ntabwo irwanya UV kandi irashobora gukoreshwa gusa murwego rwo kwirinda izuba ryinshi. Ugereranije fibre ya UHMWPE na nylon, aramid hamwe na modulus ndende na modulus nkeya, imbaraga zo kugumana fibre UHMWPE ziri hejuru cyane ugereranije nizindi fibre.
6.Ibindi bintu bya fibre ya UHMWPE
Fibre ya UHMWPE nayo ifite umutungo mwiza wa hydrophobique, amazi nubushuhe bwamazi, umutungo wamashanyarazi hamwe nubuzima burebure. Nibikoresho byonyine byubuhanga buhanitse bishobora kureremba hejuru y'amazi, kandi nibikoresho byiza byubushyuhe buke.
Ariko kandi ifite ibibi byayo, ni ukuvuga ko gushonga ari muke. Mugihe cyo gutunganya, ubushyuhe ntibushobora kurenga 130 ℃, bitabaye ibyo, ibintu bikururuka bizabaho kandi ubuzima bwa serivisi buzagabanuka kubera imbaraga nke ziri hagati yiminyururu ya molekile ya fibre UHMWPE. Nta tsinda ryo gusiga irangi kuri fibre ya UHMWPE, ituma ubukonje bwayo bubi. Biragoye ko irangi ryinjira muri fibre, bikavamo imikorere mibi yo gusiga irangi. Izi nenge zigira ingaruka kubikorwa byazo.
