Ibicuruzwa

Polyurethane (PU), izina ryuzuye ni polyurethane, ni polymer compound.Yakozwe na Otto Bayer mu 1937.Polyurethane igabanyijemo ibyiciro bibiri: ubwoko bwa polyester n'ubwoko bwa polyether.Birashobora gukorwa muri plastiki ya polyurethane (cyane cyane plastiki ifuro ifuro), fibre polyurethane (bita spandex mubushinwa), reberi ya polyurethane na elastomers.

Polyurethane yoroshye cyane ni imiterere yumurongo wa termoplastique, ifite ituze ryiza, irwanya imiti, imbaraga hamwe nubukanishi kuruta ibikoresho bya PVC, kandi bifite ihindagurika rito.Ifite ubushyuhe bwiza, kubika amajwi, kurwanya ihungabana no gukora anti-virusi.Kubwibyo, ikoreshwa nko gupakira, kubika amajwi, gushungura ibikoresho.

Plastike ya polyurethane yoroheje nuburemere, nziza cyane mukuzuza amajwi no kubika ubushyuhe, kurwanya imiti, ibikoresho byiza byamashanyarazi, gutunganya byoroshye, no kwinjiza amazi make.Ikoreshwa cyane mubwubatsi, ibinyabiziga, inganda zindege, ibikoresho byubaka ubushyuhe.

Imikorere ya polyurethane elastomer iri hagati ya plastiki na reberi, kurwanya amavuta, kwihanganira kwambara, kurwanya ubushyuhe buke, kurwanya gusaza, gukomera cyane na elastique.Ahanini ikoreshwa mubikorwa byinkweto ninganda zubuvuzi.Polyurethane irashobora kandi gukoreshwa mugukora ibifatika, gutwikira, uruhu rwubukorikori, nibindi.

Polyurethane yagaragaye muri 1930.Nyuma yimyaka hafi 80 yiterambere ryikoranabuhanga, ibi bikoresho byakoreshejwe cyane mubijyanye nibikoresho byo munzu, ubwubatsi, ibikenerwa bya buri munsi, ubwikorezi, nibikoresho byo murugo.
