Zogulitsa za polyurethane makamaka zimaphatikizapo mitundu iyi: mapulasitiki a thovu, ma elastomers, mapulasitiki opangidwa ndi fiber, ulusi, utomoni wa nsapato zachikopa, zokutira, zomatira ndi zosindikizira, zomwe mapulasitiki a thovu ndi omwe amakhala ambiri.

polyurethane thovu pulasitiki

Chithovu cha polyurethane chimagawidwa kukhala chithovu cholimba ndi mitundu 2 ya thovu yofewa, imakhala ndi kutha kwabwino kwambiri, elongation, mphamvu yopondereza ndi kufewa, komanso kukhazikika kwamankhwala abwino.Kuphatikiza apo, thovu la polyurethane lilinso ndi ntchito yabwino kwambiri, zomatira, zotsekemera ndi zinthu zina, ndizomwe zimagwira ntchito bwino kwambiri.

Kupanga zinthu za polyurethane kwafalikira ku North America konse.Akuti kuchuluka kwapachaka kwa msika waku North America polyurethane thovu akuyembekezeka kufika pafupifupi 6%.Kukula kumayembekezeredwa kuyang'ana pa ntchito zogona ndi mafakitale za thovu la polyurethane lopopera, komanso ntchito zankhondo kupyolera mu 2020. Kuwonjezera apo, polyurethane idzagwiritsidwanso ntchito m'makampani azachipatala kuti athetse mabala panthawi yake komanso ogwira ntchito.

polyurethane elastomer

Chifukwa cha mawonekedwe ake okhala ndi zigawo ziwiri zofewa komanso zolimba, ma polyurethane elastomers amatha kupatsidwa mphamvu zambiri, kulimba bwino, kukana kuvala, kukana mafuta ndi zinthu zina zabwino kwambiri kudzera pamapangidwe a unyolo wa maselo.Polyurethane, yomwe imadziwika kuti "rabala yosamva kuvala", imakhala ndi mphira wonyezimira komanso wosasunthika wa pulasitiki.

M'chaka chatha, chifukwa cha kuchepa kwakukulu kwa mtengo wamafuta osakanizidwa, pokhudzana ndi vuto lachuma padziko lonse lapansi, kukula kwa msika wa polyurethane elastomer m'dziko lathu poyerekeza ndi zaka zam'mbuyomu, kukula kwapang'onopang'ono, kusalinganika kwa zinthu. ndi kuchuluka kwa kufunikira kunapangitsa mtengo wa polyurethane elastomer mpaka pansi.Komabe, izi zimangowoneka muzinthu zachikhalidwe za polyurethane.Zomwe zili muukadaulo komanso luso lapamwamba lazinthu zamtundu wa elastomer monga ziyembekezo za msika wa nano polyurethane elastomer, kapena zochulukirapo.
