Imbaraga nyinshi cyane modulus polyethylene fibre fibre yerekanye imikorere yayo
(1) Kurwanya ingaruka nziza
Fibre ya UHMWPE ni fibre ya termoplastique ifite ubushyuhe buke bwikirahure.Ifite ubukana bwiza kandi ikurura imbaraga murwego rwo guhindura plastike.Kubwibyo, ibikoresho byayo byose biracyafite imiterere yubukanishi ku gipimo cyinshi n'ubushyuhe buke.Ingaruka zo guhangana nazo ziruta iz'ibikoresho bya karubone, fibre ya arylon hamwe n'ibirahure bya fibre.Ingaruka zihariye imbaraga zose zo kwinjiza Et / P ya fibre ya UHMWPE ni 1.8, 2,6 na 3 inshuro 3 za fibre karubone, fibre ya aramide na E ikirahure cya E.Ubushobozi bwamasasu ya UHMWPE fibre yibikoresho bikubye inshuro 2,5 kurenza fibre ya aramide.Imbaraga zingaruka za fibre ya UHMWPE isa nkiya nylon, kandi imbaraga zo kwinjiza fibre ya UHMWPE mugihe cyihuta cyikubye kabiri fibre ya PPTA na nylon.Iyi mikorere irakwiriye cyane gukora ibikoresho bitagira amasasu.
(2) Imikorere myiza yo kunama
Uburemere buke bwa polyethylene fibre ifite ibyiza byo kugonda kandi irashobora gukora ibishishwa byo kuboha no gupfundika imitwe itavunitse.Ibikoresho byunama bya fibre fibre, fibre karubone na fibre ya arylon ni bibi.Kugereranya ibintu bitunganijwe bya fibre zitandukanye byerekana ko uburemere buke bwa polyethylene ifite imbaraga nyinshi zo guhuza hamwe nimbaraga zo gukora impeta, kandi fibre ya UHMWPE ifite impeta nziza kuruta gukora fibre aramid.
(3) Kurwanya fibre
Imikorere ya fibre ya HSHMPE biterwa nubushyuhe nuburemere bwibidukikije bikora.Imikorere ya fibre ya HSHMPE kuri 35 ℃ na 1g / d umutwaro irerekanwa mumbonerahamwe 3. Ugereranije na fibre isanzwe, imikorere yo kurwanya fibre ya HSHMPE ni nziza.
(4) kurwanya neza ubuhehere no kurwanya ruswa
Kubera imiterere yoroshye yimiti ya polyethylene, ifite imbaraga zo kurwanya ruswa.Ibicuruzwa bikozwe muri fibre ntibizatakaza imbaraga zoguhuza na acide, alkalis, amazi yinyanja yanduye, nibindi. kugirango rero wirinde neza isuri ya molekile zamazi na reagent ya chimique, kugirango igire imbaraga zo kwihanganira ibishishwa.Fibre ya Spectra igumana imbaraga zayo rwose iyo yibijwe igice cyumwaka mubitangazamakuru bitandukanye, nk'amazi, amavuta, aside, hamwe nibisubizo fatizo.Fibre ya Spectra igumana imbaraga zayo nyuma yo kwibizwa mumazi mugihe cyimyaka ibiri kandi ikanarwanya ruswa.Imbonerahamwe 1 - 8 yerekana imbaraga zo kugumana fibre ya Spectra na Kevlar fibre mubitangazamakuru bitandukanye byimiti.UHMWPE fibre ya macromolecular ntabwo irimo impeta ya aromatiya, itsinda rya amino, itsinda rya hydroxyl cyangwa andi matsinda yimiti yibasiwe nigitero cya reagent, kristaliste ni ndende, bityo imbaraga mubidukikije bitandukanye bya caustic zikabikwa hejuru ya 90%, mugihe fibre ya aramide muri acide ikomeye, base base igabanuka cyane.
(5) Kwambara ibiturwanya
Kwambara kwangirika kwibintu muri rusange bigabanuka hamwe na modulus nini, ariko kuri fibre ya UHMWPE, icyerekezo ni ikinyuranyo, ibi biterwa na coefficient nkeya yo guterana, bityo ikagira igihe kirekire.Spectra900PE umugozi wa fibre ufite inshuro 8 zirenga zingana numero N ugereranije na fibre aramide, kandi ifite imbaraga zo kwambara no kunama umunaniro kuruta fibre ya aramide.Kubera gutunganya byoroshye, ifite ibyifuzo byiza byo gusaba mu nganda.Kwambara birwanya UHMWPE mu ikamba rya plastiki, inshuro nyinshi kuruta ibyuma bya karubone, Huang Gang irwanya kwambara, kwambara kwayo gukubye inshuro nyinshi kurenza polyethylene isanzwe, kandi hamwe na misile ihanitse cyane, imikorere irwanya kwambara iratera imbere kurushaho, ariko nyuma yigihe iyo misile igereranije igeze ku gaciro runaka, kutambara kwayo ntigukomeza guhinduka hamwe na misile ihanitse.
(6) Gukwirakwiza amashanyarazi no kurwanya urumuri
Ikwirakwizwa rya fibre ya UHMWPE yongerewe imbaraga kuri radar waves irarenze iy'ibirahuri bya fibre byongerewe imbaraga kubera agaciro ka dielectric gahoraho hamwe na dielectric gutakaza agaciro na bake bagaragaza imiraba ya radar.Dielectric ihoraho yibikoresho bya polyethylene hamwe nigiciro cyo kuzigama ingufu ni nto, bikwiranye no gukora radome zitandukanye.Mubyongeyeho, imbaraga za dielectric ya UHMWPE ni 700kV / mm, zishobora kugenzura ihererekanyabubasha rya arc na spark yamashanyarazi.
Ndetse na nyuma yo kumurika 1500h, igipimo cyo kugumana imbaraga za fibre UHMWPE ni 68%, mugihe izindi fibre ziri munsi ya 50%.
