Ma polyurethanes amapezeka pafupifupi kulikonse m'moyo wamakono;mpando umene mwakhalapo, bedi limene mumagonamo, nyumba imene mumakhala, galimoto imene mumayendetsa - zonsezi, kuphatikizapo zinthu zina zosawerengeka zomwe mumagwiritsa ntchito zili ndi polyurethanes.Chigawochi chikuyang'ana zina mwazogwiritsidwa ntchito kwambiri za polyurethanes ndikupereka chidziwitso pakugwiritsa ntchito kwawo.

Kodi chimapezeka kuti?

Zopaka

Zovala zamakono zambiri, kaya za magalimoto ndi zingwe, pansi ndi makoma, kapena milatho ndi misewu, zimakhala ndi ma polyurethanes, omwe amateteza mosamala ndi mogwira mtima malo owonekera kuchokera kuzinthu ndi mitundu yosiyanasiyana ya kuipitsa, kuti awoneke bwino komanso okhalitsa.

Kukhazikika, kukana kwa dzimbiri komanso kukana kwa nyengo kwa polyurethanes kumawapangitsa kukhala oyenera kupaka mitundu yonse ya malo.Ntchito zimachokera ku zomanga za konkriti monga milatho ndi misewu, mpaka kumagalimoto azitsulo ndi mipando yamatabwa.

Zomatira / zomangira

Ma polyurethanes ndi osinthika kwambiri kotero kuti amapezekanso ngati zomatira zomwe zimatha kumangirira pamodzi zinthu zosiyanasiyana, monga matabwa, mphira, makatoni kapena galasi.

Ntchito zomanga, makamaka, zimagwiritsa ntchito zomatira za polyurethane.Opanga ma CD ndi opanga mipando yakunja, omwe amafunikira kulimba mtima komanso mphamvu pazogulitsa zawo, nthawi zambiri amadalira zomatira za polyurethane.

Ma polyurethanes ndi othandiza popanga zida zatsopano zopangidwa kuchokera kuzinthu zotayidwa ndi zobwezerezedwanso.Mwachitsanzo, matayala agalimoto otha kugwiritsidwa ntchito amatha kupangidwa kukhala mabwalo amasewera a ana, mabwalo amasewera kapena malo ochitira masewera chifukwa cha zomatira za polyurethane.
