Umwanya wo gusaba hamwe niterambere ryiterambere ryibikoresho bya polyurethane

Polyurethane elastomers ni iyumwanya wa polymers, ni ukuvuga macromolecules ya polyurethane igizwe n "ibice byoroheje" n "" ibice bikomeye "kandi ikora imiterere yo gutandukanya micro.Ibice bikomeye (bikomoka kuri isocyanates no kwagura urunigi) bikwirakwizwa mu gice cyoroheje cyicyiciro (gikomoka kuri oligomer polyol) kandi kigira uruhare rwibintu bifatika.Kubwibyo, ugereranije nizindi reberi yubukorikori (elastomers), elastomers ya polyurethane ifite imbaraga nziza no kwambara birwanya, Kurambura cyane birashobora gukomeza kubaho mugihe ubukana buri hejuru.

Ibikoresho bya Elastique polyurethane, byitwa "urubanza" mu bihugu by’amahanga, birimo cyane cyane ibicuruzwa gakondo bya polyurethane elastomer, umuhanda wa pulasitike wa polyurethane hamwe n’ibindi bikoresho bya kaburimbo, ibishishwa bitarimo amazi ya polyurethane, ibifunga, ibifunga, ibumba, n'ibindi, bingana na 40% bya umubare wibicuruzwa bya polyurethane.Ibyinshi mubicuruzwa byakize byibikoresho byimanza (ibicuruzwa bishingiye kumazi nibikomoka kumashanyarazi bikuraho amazi nibishishwa) nibikoresho bya polyurethane bidafite ifuro.PU synthique yimpu isukuye, ibifuniko bimwe na bimwe bifata ibicuruzwa biva mumazi cyangwa ibicuruzwa byamazi, bishobora no gufatwa nkibikoresho bya polyurethane elastomer muburyo bwagutse.Mu buryo bugufi, polyurethane elastomer bivuga casture polyurethane elastomer (CPU), polymuretique polyurethane elastomer (TPU) hamwe na polyurethane ivanze (MPU), bingana na 10% cyangwa munsi ya polyurethane yose.CPU na TPU ningenzi elastomers ya polyurethane, kandi itandukaniro ryabo riri mubintu nkibikorwa byo kongera umusaruro no kwagura urunigi.Ubu bwoko bwa polyurethane elastomer, buzwi kandi nka "polyurethane rubber", ni ubwoko bwa reberi idasanzwe.Imikorere ihanitse ya polyurethane elastomer nigikoresho gifite imbaraga zo kurwanya kwambara neza mubikoresho byose bya polymer.Birazwi nk "umwami wo kurwanya kwambara".Irakoreshwa cyane mubice byinshi, kandi porogaramu nshya ziracyaguka.

Polyurethane elastomers irashobora gukoreshwa mugusimbuza ibyuma, plastike na reberi isanzwe mubice bimwe.

Ugereranije nibikoresho byuma, polyurethane elastomer ifite ibyiza byuburemere bworoshye, urusaku ruke, kwihanganira igihombo, igiciro gito cyo gutunganya no kurwanya aside.Ugereranije na plastiki, ifite ibyiza byo gukomera no kwihanganira kwambara cyane.Ugereranije na reberi isanzwe, polyurethane elastomer ifite ibyiza byo kwihanganira kwambara, kugabanya kurwanya, kurira amarira, ubushobozi bwo gutwara cyane, kurwanya ozone, gukora byoroshye, kubumba no gusuka, hamwe nubunini bugari.

Polyurethane elastomer nubwoko butandukanye bwa polyurethane.Kugeza ubu, imikoreshereze yacyo igera hafi 10% y’ikoreshwa rya polyurethane.Polyurethane elastomer ikoreshwa mugukora ubwoko bwose bwibiziga bya reberi, imikandara ya convoyeur, imiyoboro irinda amazi n’umuvuduko ukabije, amabati hamwe nimpeta, kashe ya kabili na firime zitandukanye.Ibicuruzwa bikoreshwa cyane mubyuma nicyuma, gukora impapuro, ubucukuzi, imashini, icapiro nizindi nganda.Polyurethane elastomer irashobora guhindurwa nizindi polymers, fibre, kuzuza ifu, nibindi kugirango bigabanye ibiciro no kunoza imikorere.
