1. Cov khoom siv hluav taws xob tsis tshua muaj cov thermal conductivity thiab cov thermal ua kom zoo. Thaum muaj qhov hnyav ntawm cov hnyuv nplaum yog 35 ~ 40kg / m3, cov thermal conductivity tsuas yog 0.018 ~ 0.024w / (m) .K), sib npaug li ntawm EPS ib nrab, yog qhov kub thermal conductivity ntawm tag nrho cov ntaub ntawv rwb thaiv tsev.
2. Cov tawv nqaij polyurethane muaj cov khoom tsis muaj pa thiab cov tsis muaj dej tsis sib haum.Rigid polyurethane muaj ib qho kaw qhov nqi ntawm ntau tshaj 90%, uas belongs rau cov khoom siv roj ntim. Nws yuav tsis nce cov thermal conductivity vim yog dej noo, los sis yuav tsis muaj cov phab ntsa dej.
3. Rigid polyurethane yog fireproof, nplaim hluav taws kub thiab kub heev resistant.Tom qab ntxiv nplaim retardants, polyurethane yog cov roj hluav taws, cov tshuaj tua nws tus kheej. Nws txoj kev khawb qhov muag yuav ncav cuag ntau dua li 250 degree Celsius, thiab nws yuav tsuas ua rau kub dua. Tsis tas li, thaum polyurethane hlawv, nws yuav tsim carbon deposition ntawm nws npaus npoo, uas yuav pab cais tawm cov npuas hauv qab.Kev zoo tiv thaiv kev sib kis ntawm cov hluav taws. Tsis tas li ntawd, polyurethane tsis tsim cov huab cua phem hauv kev sov siab.
4. Raws li lub tshuab ua hluav taws xob (polyurethane (pu) ua npuas hluav taws xob ua kom zoo, nws tuaj yeem txo qhov tuab ntawm cov qauv kev tiv thaiv ntawm lub tsev thiab ua kom thaj chaw zoo siv hauv vaj tse hauv qab tib yam kev txuag hluav taws xob.
5. Muaj peev xwm ua kom muaj kev sib deev, tsis yooj yim tawg, ruaj khov thiab zoo nkauj zoo nkauj.
6. Cov ntaub pua tsev polyurethane ruaj khov muaj cov dej khov ruaj khov thiab yeej yog ib lub qauv pore, uas tsis tsuas muaj cua sov thermal rwb thaiv tsev zoo, tab sis kuj tau zoo tiv thaiv kom khov, yaj thiab lub suab nqus.Qhov nruab nrab ntawm lub neej ntawm polyurethane rwb thaiv tsev muaj peev xwm mus txog ntau tshaj 30 xyoo raws li kev siv thiab txij nkawm. Cov qauv no feem ntau yuav siv thaum lub neej ntawm tus qauv nyob rau hauv qhuav, ntub los yog electrochemical corrosion, thiab raws li kev loj hlob ntawm kab, fungi los yog algae los yog vim muaj kev puas tsuaj thiab lwm yam lwm yam, uas yuav tsis raug puas ntsoog.
7. Muaj txiaj ntsim zoo rau kev ua haujlwm.Txawm hais tias tsis tau muaj ntaub npog polyurethane muaj nqi ntau dua li lwm cov ntaub ntawv pov thawj cov khoom pov tseg, qhov nqi yuav raug them los ntawm qhov txo qis cua kub thiab cua txias.
