Ukukhetha Igwebu Elilungile Lokufutha I-PU Ngezidingo Zakho Zokumisa

I-spray polyurethane foam (SPF) insulation isiphenduke into ethandwayo kubanikazi bezindlu nosonkontileka abafuna ukwandisa ukusebenza kahle kwamandla nokunciphisa izindleko zokushisisa nokupholisa. Kodwa-ke, ngezinhlobo ezahlukahlukene zegwebu le-PU lesifutho elitholakala emakethe, ukukhetha elifanele ngezidingo zakho zokufakelwa kungaba umsebenzi onzima. Kulesi sihloko, sizoxoxa ngezinto ezibalulekile okufanele uzicabangele lapho ukhetha igwebu le-PU lesifutho elifanele lephrojekthi yakho.

Ukuqonda Izinhlobo ze-Spray PU Foam

Kunezinhlobo ezimbili eziyinhloko ze-spray PU Foam: iseli elivulekile kanye neseli elivaliwe. Igwebu elivulekile leseli lilula futhi lishibhile, okwenza kube ukukhetha okudumile kwezinhlelo zokusebenza zangaphakathi. Kuyisithiyo esihle kakhulu somoya kodwa hhayi umgoqo womhwamuko. Igwebu lamaseli avaliwe, ngakolunye uhlangothi, liminyene futhi liqinile, linikeza inani eliphakeme le-R futhi lisebenza njengokubili isithiyo somoya kanye nomhwamuko. Igwebu lamaseli avaliwe ngokuvamile lisetshenziselwa izinhlelo zokusebenza zangaphandle lapho ukulawulwa komswakama kubaluleke kakhulu.

Uma ukhetha phakathi kwe-open-cell kanye ne-close-cell foam, cabangela izici ezifana nesimo sezulu, ukwakheka kwesakhiwo, kanye nesabelomali. Igwebu lamaseli avaliwe liyatuswa ezindaweni ezithambekele ekubeni nomswakama ophezulu noma umswakama, kuyilapho igwebu lamaseli avulekile lifanele izindonga zangaphakathi noma ophahleni lapho ukulawulwa komswakama kungenakukhathazeka kangako.

Kucatshangelwa i-R-Value kanye nokusebenza kahle kwamandla

Inani le-R likala ukumelana nokushisa kwento ethile, enenani elingu-R eliphakeme elibonisa ukusebenza okungcono kokufakwa. Lapho ukhetha isifutho se-PU Foam, cabanga ivelu engu-R yomkhiqizo ukuze uqiniseke ukuthi uhlangabezana nezidingo zokonga kwamandla kuphrojekthi yakho. Igwebu lamaseli avaliwe ngokuvamile linenani elingu-R eliphakeme kunegwebu lamaseli avulekile, okulenza libe isivikelo esisebenza kahle kakhulu.

Ngokungeziwe ku-R-value, cabangela izici ezifana nokuvala umoya nokulawula umswakama lapho uhlola ukusebenza kahle kwamandla kwegwebu le-PU lesifutho. Ukuvaleka kahle nokuvala umoya kunganciphisa kakhulu izindleko zokushisisa nokupholisa, kuthuthukise ukunethezeka kwasendlini, futhi kuthuthukise ukusebenza kahle kwamandla ebhilidi.

Ukuhlola Amasu Okufaka

Inqubo yokufaka i-spray PU Foam ingahluka kuye ngohlobo lwegwebu kanye nendlela yokufaka isicelo. Amanye amagwebu okufutha adinga imishini ekhethekile kanye nezingcweti eziqeqeshiwe ukuze zifakwe, kanti ezinye zingasetshenziswa kusetshenziswa amakhithi e-DIY kumaphrojekthi amancane.

Ngaphambi kokukhetha igwebu le-PU lesifutho, hlola amasu okufaka nezidingo ezihlobene nomkhiqizo. Cabangela izici ezifana nesikhathi sokwelapha, izinga lokushisa lohlelo lokusebenza, nezinyathelo zokuphepha lapho unquma igwebu elifaneleka kakhulu lezidingo zakho zokufaka.

Ukuqonda Umthelela Wezemvelo

Umthelela wemvelo uwukucatshangelwa okubalulekile lapho ukhetha igwebu le-PU lesifutho lephrojekthi yakho yokufakelwa. Eminye imikhiqizo yegwebu inamakhemikhali ayingozi njenge-formaldehyde noma i-volatile organic compounds (VOCs), engaba nomthelela omubi kwikhwalithi yomoya wasendlini kanye nemvelo.

Ukuze unciphise umthelela wendawo, bheka amagwebu e-PU esifutho aqinisekiswe i-low-VOC noma angenawo amakhemikhali ayingozi. Khetha imikhiqizo enezitifiketi zemvelo efana ne-GREENGUARD noma i-ENERGY STAR ukuze uqinisekise ukuthi iphrojekthi yakho yokufakelwa ithuthukisa izinga lomoya wasendlini kanye nokusimama.

Ukuqhathanisa Izindleko Nokuqina Kwesikhathi Eside

Izindleko ziyisici esibalulekile okufanele sicatshangelwe lapho ukhetha igwebu le-PU lesifutho ngezidingo zokufakelwa. Nakuba igwebu lamaseli avulekile ngokuvamile lishibhile kunegwebu lamaseli avaliwe, lingadinga izithiyo zomoya ezengeziwe kanye nomhwamuko ukuze kuzuzwe izinga elifanayo lokusebenza. Igwebu lamaseli avaliwe, nakuba libiza kakhulu, linikeza izakhiwo eziphakeme zokugqumisa kanye nokuqina kwesikhathi eside, okungenzeka konga imali ezindlekweni zamandla ngokuhamba kwesikhathi.

Uma uqhathanisa izindleko, cabangela ukuqina nokusebenza kwesikhathi eside kwegwebu le-PU lesifutho. Linganisa izinto ezifana newaranti, izidingo zokunakekela, nokonga amandla okungase kube khona ukuze unqume inani elingcono kakhulu lephrojekthi yakho yokufakelwa.

Sengiphetha, ukukhetha isifutho esilungile segwebu le-PU ngezidingo zakho zokufakelwa kudinga ukucatshangelwa ngokucophelela kwezinto ezinjengohlobo, inani le-R, amasu okufaka, umthelela wendawo, izindleko, nokuqina kwesikhathi eside. Ngokuqonda lezi zici ezibalulekile nokuhlola izidingo zephrojekthi yakho, ungakhetha igwebu lesifutho elihlinzeka ngokusebenza kahle kwamandla, ukunethezeka, nokusimama kwesakhiwo sakho. Yenza isinqumo esinolwazi lapho ukhetha isifutho se-PU Foam ukuze uzuze imiphumela engcono kakhulu yephrojekthi yakho yokufakelwa.
