Foam yepolyurethane yakapfapfaidzwa (SPF) chinhu chinodzivirira kupisa chakavakirwa pamakemikari, uye nekuti chinhu chakapfapfaidzwa nefuro hachikanganisike nekufamba kwenguva, chinowanzoshandiswa musystem yekudzivirira kupisa mudzimba. Ine zvikamu zviviri zvikuru: isocyanates nemusanganiswa wezvinowedzera, zvinosanganisira polyols uyezvinokonzeresa, izvo zvinosanganiswa panzvimbo yacho kuti zvigadzire layer yakasimba yekudzivirira kupisa. Kune mhando mbiri huru dzefuro rekupfapfaidza: furo remasero akavhurika uye furo remasero akavharika, imwe neimwe ine hunhu hwakasiyana uye mashandisirwo akasiyana.
Furo reSpray reMasero Akavhurika
Furo re spray rine maburi akavhurika rine mutengo wakaderera uye rinokura zvakanyanya, uye rinogona kusarudzwa kana richizadza Nzvimbo dzakakura. Nekuda kwehuwandu hwaro hwepamusorokuchinjika, inogona kubviswa zviri nyore uye inogonawo kuzadzwa nechinhu chinodzivirira makona akaoma kusvika. Furo remasero akavhurika rine chimiro chemasero chakafanana nemabhuru madiki ane maburi anobvumira mhepo kutenderera. Kunyange zvazvo ichipa kusimba kwemhepo, haipe hunyoro nekuti kupinda kwayo kunobvumira mvura kupfuura nepakati. Ine R-value (chiyero chekugona kwayo kudzivirira ngura) yeinenge 3.5 kusvika 3.8 pa inch, zvichiita kuti ive yakakodzera kushandiswa uko kunodiwa kuyerera kwemhepo asi kuramba hunyoro hakusi kwakakosha. Inowanzoshandiswa mumadziro emukati, maattics, nenzvimbo dzinoda kudzivirira ngura, sezvo kuvakwa kwayo kwemaburi akavhurika kuchipawo kudzikisa ruzha kwakanaka.
Furo reSpray reMasero Akavharwa
Maburi akabatanidzwa zvakasimba kuti agadzire chimiro chakasimba anonzi mafoam emasero akavharwa. Foam yekupfapfaidza ine mavharo akaomarara uye akasimba, zvichiita kuti pave nechidziviriro chakasimba kubva kumhepo nehunyoro. Maburi ayo akavharwa anodzivirira mhepo nehunyoro kuti isapinde, zvichiita kuti ive chidziviriro chinoshanda chehunyoro. Inokura nekukurumidza pane furo remasero akazaruka, asi inochengetedza hunyoro zviri nani, ine R kukosha kweinenge 6.0 pa inch. Kana R-value yakakwira, furo remasero akavharwa rinodzivirira kupisa, zvichiita kuti rive rakakodzera kushandiswa kunze kunoda insulation yakakwira uye dziviriro yehunyoro, senge matenga, nheyo, nemadziro. Pasinei nemutengo wakakwira, furo remasero akavharwa rinowanzo shandiswa munzvimbo dzine nzvimbo shoma asi insulation yakanyanya inodiwa.
Muchidimbu, mafoam ekupfapfaidza ane ma cell akavhurika neakavharwa anoshanda se insulators asi akasiyana muhunhu hwawo uye mashandisirwo awo. Foam yakavhurika ine mutengo wakaderera, inowedzera kuwanda, uye inobvumira kutenderera kwemhepo, nepo foam yakavharika ine denderedzwa, inoshanda sechidziviriro chehunyoro, uye inopa R-value yakakwira. Sarudzo pakati pezviviri izvi inoenderana nezvinodiwa zvepurojekiti chaiyo, kusanganisira dziviriro yehunyoro, kushanda zvakanaka kwe insulation, uye bhajeti.
