Imirima ikoreshwa hamwe niterambere ryiterambere ryibikoresho bya polyurethane

Polyurethane elastomers ni iyumubyimba wa polymers, ni ukuvuga macromolecules ya polyurethane igizwe n "ibice byoroheje" n "" ibice bikomeye "kandi ikora imiterere yo gutandukanya micro-fonction, aho ibice bikomeye (biva muri isocyanates no kwagura urunigi) bikwirakwizwa muri yoroshye igice cyicyiciro cyakarere (kuva oligomer polyoli) kugirango ukine uruhare rwumubiri uhuza ingingo.Kubwibyo, ugereranije nizindi reberi ya sintetike (elastomers), elastomers ya polyurethane ifite imbaraga nziza no kwambara birwanya, kuramba birashobora gukomeza kubaho mugihe ubukana buri hejuru.

Ibikoresho bya Elastike polyurethane, byitwa "URUBANZA" mu mahanga, birimo ibicuruzwa bya polyurethane gakondo bya elastomer, ibikoresho byo gusasa nka polyurethane yumuhanda wa pulasitike, ibishishwa bitarimo amazi ya polyurethane, ibifunga, kashe, ibibumbano, nibindi, bingana na 40% byamafaranga yose hamwe y'ibicuruzwa bya polyurethane.Ibyinshi mubicuruzwa byakize byibikoresho bya CASE (ibicuruzwa bishingiye kumazi nibishobora gukemuka nyuma yo kuvanaho amazi na solge) ni ibikoresho bya polyurethane bidafite ifuro.PU yubukorikori bwuruhu rwa PU, ibifuniko bimwe na bimwe bifata ibicuruzwa biva mumazi cyangwa bishingiye kumazi, bishobora no gufatwa nkibikoresho bya polyurethane elastomer muburyo bwagutse.Mu buryo bugufi, elastomers ya polyurethane yerekeza kuri elastomers ya polyurethane (CPU), elastomers ya termoplastique polyurethane (TPU) hamwe na polyurethane ivanze (MPU), bingana na 10% cyangwa munsi yumubare muto wa polyurethane.CPU na TPU nibyo byingenzi bya polyurethane elastomers, kandi itandukaniro ryabo riri mubikorwa byo kongera umusaruro no kwagura urunigi.Ubu bwoko bwa polyurethane elastomer, buzwi kandi nka "polyurethane rubber", ni ubwoko bwihariye bwa reberi.Polyurethane elastomer ikora cyane nibikoresho byiza birwanya kwambara mubikoresho byose bya polymeriki ya sintetike, izwi nka "king of resistance resistance", kandi ikoreshwa cyane mubice byinshi, kandi porogaramu nshya ziracyaguka.

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

Ugereranije nibikoresho byibyuma, polyurethane elastomer ifite ibyiza byuburemere bworoshye, urusaku ruke, kwihanganira kwambara, 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, nibindi, kandi byoroshye kuyikora, irashobora kubumba, gusukwa, kandi ifite ubukana bwinshi.
