Nyob rau hauv xyoo tas los no,dej -Blown Spray Polyurethane ua npuas ncauj (SPF) rwb thaiv tsevtau dhau los ua ib qho ntawm - loj hlob kev daws teeb meem hauv ntiaj teb kev lag luam rwb thaiv tsev. Raws li ib puag ncig cov cai nruj,polyether polyols rau nruj ua npuas ncaujua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov ua tau zoo kawg ntawm cov tshuab ua npuas dej.
Lub luag haujlwm tseem ceeb ntawm Polyether Polyols hauv SPF Systems
Polyether polyols yog cov caj qaum ntawmnruj polyurethane ua npuas ncauj rwb thaiv tsev. Hauvdej- tshuab tshuab, dej reacts nrog isocyanate los tsim CO₂, tsim cov qauv ua npuas ncauj. Kev xaiv ntawm polyether polyol ncaj qha cuam tshuam rau:
Ua npuas ncauj ntom ntom
Thermal rwb thaiv tsev kev ua tau zoo (tsawg thermal conductivity)
Dimensional stability
Adhesion zog
High -zooSpray ua npuas ncauj polyether polyolsxyuas kom cov qauv ntawm tes zoo sib xws thiab txhim kho kev ua haujlwm ntawm rwb thaiv tsev, uas yog qhov tseem ceeb rau kev siv lub ru tsev, phab ntsa rwb thaiv tsev, thiab kev siv cov khoom txias.
Qhib-Cell vs Closed-Cell Foam Performance
Kaw-cell spray foam insulationmuab cov rwb thaiv tsev zoo dua (qis λ tus nqi), siab compressive zog, thiab zoo heev ya raws.
Qhib -cell spray foam insulationmuab kev yooj yim, lub suab nqus, thiab tus nqi zoo.
Txoj caipolyether polyol formulationtxiav txim siab seb cov npuas dej puas ua tau zoo qhib -cell los yog kaw - cell qauv.
Yog vim li cas dej-Blown Systems yog Trending
Piv nrog cov tshuaj tshuab tshuab ib txwm muaj,dej- tshuab polyurethane ua npuas ncaujyog:
Ib puag ncig tus phooj ywg (zero ODP)
Tus nqi- zoo
Ua raws li kev cai thoob ntiaj teb
Qhov no ua rau nws txaus nyiam heev rau cov neeg cog lus thiab cov neeg xa khoom thoob ntiaj teb.
