I-polyurethane foam inezinzuzo eziningi futhi ezibalulekile. Okokuqala, umthamo wayo wokunweba oyingqayizivele. Ngemuva kokufuthwa, igwebu likhula ngokushesha libe izikhathi ezingama-20-80 umthamo walo wokuqala, noma ngaphezulu. Lokhu kuvumela ukuthi igcwalise ngokuphumelelayo izikhala ezingavamile kanye nama-pores, ukugwema izinkinga zemfucuza kanye nokungalingani okuhambisana nokugcwaliswa kwendabuko.
Okwesibili, ibonisa amandla okubopha okuphezulu. Igwebu elilashiwe le-polyurethane lakha igwebu eliqinile elinamathela ngokuqinile kuma-substrates ahlukahlukene njengokhuni, insimbi, nokhonkolo. Amandla ayo okugunda afinyelela ku-0.5-1.0 MPa, adlula kude lawo okunamathelayo ajwayelekile. Lokhu kuyenza ivelele ekuqinisweni kwesakhiwo.
Ukuvimbela amanzi kanye nezindawo zokushisa ezishisayo kungenye into egqamile. Isilinganiso-seseli elivaliwe legwebu ngokuvamile lingaphezu kuka-90%, livimbela ngempumelelo ukungena komswakamo futhi liwenze lifanelekele izindawo ezinomswakama. Ngasikhathi sinye, ukuguquguquka kwayo okuphansi kwe-thermal (okungaba ngu-0.02-0.03 W/m·K), izikhathi eziningana kunezinto ezijwayelekile zokufaka ugesi, kuyenza isetshenziswe kabanzi ekwakheni ukonga amandla.
Ngaphezu kwalokho, i-polyurethane foam nayo inezakhiwo ezinhle zokuvikela umsindo. Izakhiwo zegwebu zimunca amagagasi omsindo futhi zinciphise ukudluliswa komsindo, ziwenze avame ukusetshenziselwa ukuvala iminyango namafasitela emhlobiso wasekhaya ukuze kuthuthukiswe ukunethezeka kokuphila. Zimelana kakhulu nokugqwala kwamakhemikhali, ukumelana nama-asidi, ama-alkali, nezinyibilikisi eziphilayo, okuzenza zilungele ukusetshenziswa kwezimboni.
Ngokombono wenyama, le nto ilula, inokuminyana okuphulukisiwe okungu-20-50 kg/m³ kuphela, okungakhulisi umthwalo wesakhiwo. Futhi inezinga elithile lokunwebeka, elikwazi ukumelana nokuguquguquka okubangelwa ukwanda nokufinyela okushisayo, okunciphisa ingozi yokuqhekeka.
Mayelana nokuvikelwa kwemvelo, izinto zokunamathisela ezinegwebu le-polyurethane zesimanje ngokuvamile zisebenzisa ukwakheka okuphansi-ku-volatile organic compound (VOC), okunciphisa ukungcoliswa komoya. Imithetho efanele, efana ne-GB 18583-2008 "Imikhawulo Yezinto Eziyingozi Ezinamathelayo Zokuhlobisa Kwangaphakathi Nokuvuselela Izinto," ibeka izimfuneko eziqinile kule mikhiqizo ukuze kuqinisekiswe ukusetshenziswa okuphephile.
Kodwa-ke, imikhawulo kufanele futhi iqashelwe, njengokuzwela ukukhanya kwe-ultraviolet kanye nokuguga{0}}okuchayeka isikhathi eside, okubenza bangafaneleki izindawo ezingaphandle ezingamboziwe. Sekukonke, nokho, lezi zici zenza izinamathiselo ze-polyurethane foam zibe izinto ezithandwayo emikhakheni eminingi.
