Zvigadzirwa zvepolurethane zvinonyanya zvinosanganisira marudzi anotevera: mapurasitiki efuro, elastomers, mapurasitiki efayibha, faibha, marezeni eshangu dzematehwe, machira, zvinonamira uye zvisimbiso, pakati peiyo mapurasitiki efuro anoita chikamu chikuru.

polyurethane furo plastiki

Polyurethane furo rakakamurwa kuita furo rakaomarara uye rakapfava furo 2 mhando, ine yakanakisa elasticity, kureba, kudzvanya simba uye kupfava, uye yakanaka kugadzikana kwemakemikari.Uye zvakare, polyurethane foam zvakare ine yakanakisa kushanda, kunamatira, kusungirira uye zvimwe zvivakwa, ndezvekuita kwakanaka kweiyo buffer zvinhu.

Kugadzirwa kwe polyurethane zvinhu zvakapararira muNorth America yese.Zvinonzi avhareji yegore yekukura kwemusika weNorth American polyurethane foam inotarisirwa kusvika pa6%.Kukura kunotarisirwa kutarisa nezvekugara uye maindasitiri ekushandiswa kwesprayed polyurethane foam, pamwe nekushandiswa kwemauto kuburikidza ne2020. Mukuwedzera, polyurethane ichashandiswawo mumhizha yezvokurapa kuitira nguva uye inobudirira kurapwa kwemaronda.

polyurethane elastomer

Nekuda kwechimiro chayo chine akapfava uye akaoma maviri cheni zvikamu, polyurethane elastomers inogona kupihwa simba rakakura, kusimba kwakanaka, kupfeka kuramba, mafuta kuramba uye zvimwe zvakanakisa zvivakwa kuburikidza nekugadzirwa kwemamorekuru cheni.Polyurethane, inozivikanwa se "wear-resistant rubber", ine yakakwira elasticity yerabha uye kuoma kwepurasitiki.

Mugore rapfuura, nekuda kwekuderera kukuru kwemutengo wemafuta asina kuchena, mumamiriro ekuderera kwehupfumi hwenyika, kukura kwemusika wepolyurethane elastomer munyika yedu zvichienzaniswa nemakore apfuura, kusimudzira kunonoka, kusaenzana kwekupa. uye chiyero chekudiwa chakakonzera zvakanyanya mutengo we polyurethane elastomer kusvika pasi.Nekudaro, chiitiko ichi chinongowanikwa mune yechinyakare polyurethane zvigadzirwa.Tekinoroji yemukati uye yakakwira dhigirii rekuvandudza kwezvigadzirwa zve elastomer senge nano polyurethane elastomer zvinhu zvemusika tarisiro, kana zvakanyanya.
