Ma polyurethanes amagwiritsidwa ntchito kwambiri ma polima omwe amapangidwa pochita ma polyols okhala ndi diisocyanates pamaso pa mankhwala monga chothandizira ndi zowonjezera.Amagwiritsidwa ntchito popanga zinthu zosiyanasiyana pafupifupi m'mafakitale onse, monga zamagetsi, zamagalimoto, nsapato, zomanga, zonyamula, ndi zina zambiri, kuti zipangidwe kukhala zachilendo ndikuwongolera zinthu za ogula ndi mafakitale.

Polyurethane ikugwiritsidwa ntchito ngati thovu lolimba la makoma ndi kutsekereza padenga, thovu losinthika mumipando, komanso zomatira, zokutira, ndi zosindikizira zamkati zamagalimoto.Zinthu zonsezi zimatha kupereka phindu121 BPSkumsika wa polyurethane pazaka zolosera za 2022-2032.

Ntchito zazikuluzikulu za polyurethane zili mu elastomers, thovu, ndi zokutira zomwe zimapereka kukana kwa ma abrasion.Ma thovu olimba a polyurethane amagwiritsidwa ntchito kwambiri ngati zida zotsekera chifukwa chophatikiza mtengo wake komanso kutsika kwa kutentha.Kuthekera kwabwino kwa kutentha kwapang'onopang'ono, kusiyanasiyana kwamapangidwe a maselo, mtengo wotsika, komanso kukana kwamphamvu kwa abrasion zonse zimathandizira kukula kwa msika.

Komabe, kusakwanira kwa nyengo, kuchepa kwa kutentha, kupsa, ndi zina zotero, zitha kulepheretsa kukula kwa polyurethane m'zaka zikubwerazi.

Chidziwitso:Zina mwazinthu / zithunzi zomwe zili m'nkhaniyi zikuchokera pa intaneti, ndipo gwero lake ladziwika.Amangogwiritsidwa ntchito kufotokoza mfundo kapena malingaliro omwe afotokozedwa m'nkhaniyi.Amangolankhulana ndi kuphunzira, ndipo sizinthu zina zamalonda.Ngati pali kuphwanya kulikonse, chonde titumizireni kuti tichotse nthawi yomweyo.
