Isitezi esisekwenzile esekwe emanzini-polyurethane esisezingeni eliphakeme luhlobo olusha lwezinto eziphansi zemvelo ezisebenza kahle kakhulu kanye namathemba abanzi wesicelo. Izitezi ezisetshenziswa ngamanzi ezisuselwa emanzini zisebenzisa ama-polyurethane asuselwa emanzini njengezinto zesisekelo, engeza ama-filler akhethekile kanye nezithasiselo, futhi zenziwa ngokulungiswa kwesayensi kokulingana kanye nokunemba. Kuyinto evinjelwe, engavikeli ukucindezelwa, ukumelana namakhemikhali, ubufakazi, futhi okulula ukuyihlanza. Ilungele umhlobiso wephansi nokuvikelwa kwezitshalo zezimboni, izindawo zokuthengisa, amakhamishini, ukucubungula kokudla nezinye izindawo.
Inqubo yokwakha esekelwe e-polyurethane yokuzibamba le-polyurethane yokuzikhandla ilula, isikhathi sokwakha sifushane, futhi singasetshenziswa ngokushesha. Inokusebenza okuhle kakhulu kokuzilinganisa futhi ikwazi ukwakha ngokushesha phansi okuyisicaba nokusheshe, kuthuthukisa kakhulu ukusebenza kokwakha. Ngasikhathi sinye, ngenxa yokusebenzisa i-polyurethane esekelwe emanzini njengezisekelo zesisekelo, izitezi ezisetshenziswa ngamanzi polyurethane zithobela izidingo zokuvikelwa kwemvelo.
Ukusetshenziswa kwama-polyure-based polyurethane fortar selveling phansi kungathuthukisa ngempumelelo ukumelana nokugqoka nokuphikisana nomhlaba, ukwelula impilo yenkonzo yomhlaba, futhi kunciphise izindleko zokulungiswa komhlaba. Ngasikhathi sinye, izici zayo zothuli nezimpawu ezihlanzekile futhi ezihlanzekile zenza ukuhlanza phansi phansi kanye nokulungiswa kwabelula futhi kusheshe.
Ngokuvamile, izitezi zokuzivikela zamanzi ze-polyurethane ezisetshenziswayo zinesici esihle kakhulu sokuvikela imvelo. Bangumhlobiso osezingeni elifanelekile nezinto zokuvikela futhi zizosetshenziswa kabanzi ngokuzayo.
