1. Rigid polyurethane board muaj cov cua sov ua haujlwm tsis zoo thiab ua tau zoo thermal. Thaum lub ntom ntom ntom ntom ntom ntawm polyurethane yog 35 ～ 40kg / m3, cov thermal conductivity tsuas yog 0.018g ～ 0.023w / (m · k), uas yog li ib nrab ntawm EPS, uas yog qhov tsawg tshaj plaws thermal conductivity ntawm txhua cov khoom siv rwb thaiv tsev.
2. Rigid polyurethane board muaj cov dej noo-pov thawj thiab kev ua dej tsis ua haujlwm. Lub cev tsis muaj zog polyurethane muaj qhov kaw ntawm tes piv ntawm ntau dua 90%, uas yog cov khoom siv hydrophobic thiab yuav tsis nce lub thermal conductivity vim kev nqus noo, thiab lub phab ntsa yuav tsis pom dej.
3. Cov nplaim hluav taws xob polyurethane yog qhov hluav taws kub-tiv taus, nplaim hluav taws-rov zoo thiab siab kub. Tom qab ntxiv nplaim nplaim hluav taws, polyurethane yog ib hom nplaim hluav taws rov zoo li tus kheej tua cov khoom tawm. Nws cov qhov muag muag tuaj yeem ncav cuag ntau dua 250 degrees Celsius, thiab nws decomposes tsuas yog kub siab dua. Ntxiv rau, polyurethane yuav nyob rau saum npoo ntawm nws cov npuas dej thaum nws hlawv. Tshauv yog tsim, thiab txheej txheej tshauv no pab txhawm rau txhawm rau ua npuas ncauj hauv qab. Muaj peev xwm tiv thaiv tau qhov kis ntawm hluav taws. Ntxiv mus, polyurethane tsis tsim cov pa phem hauv chaw sov.
4. Vim tias muaj kev tiv thaiv zoo thaum tshav kub kub ua haujlwm ntawm polyurethane board, lub thickness ntawm txheej tiv thaiv sab nrauv ntawm lub tsev tuaj yeem raug txo qis hauv tib lub rwb thaiv tsev thermal, yog li ua rau thaj chaw siv sab hauv.
5. Muaj zog tiv thaiv ua rau deformation, tsis yooj yim rau tawg, ruaj khov thiab ruaj ntseg ua tiav.
6. Cov khoom siv polyurethane muaj cov qauv zoo nkauj thiab lub hauv paus kaw lub ntsej muag, uas tsis tsuas yog muaj kev ua tau zoo rwb thaiv tsev, tab sis kuj muaj qhov zoo khov-thaw tsis kam thiab suab zoo. Lub neej nruab nrab ntawm nruj ua npuas ncauj polyurethane rwb thaiv tsev qauv yuav ncav cuag ntau dua 30 xyoo nyob rau hauv kev siv thiab txij nkawm kev mob. Nyob hauv cov xwm txheej ib txwm muaj ntawm kev siv thaum muaj lub neej nyob ntawm tus qauv, tus qauv yuav tsis raug puas ntsoog, qhuav, lossis xeb hluav taws xob, thiab vim muaj kev cuam tshuam sab nraud xws li kev loj hlob ntawm kab, fungi lossis algae, lossis kev rhuav tshem cov nas.
7. Muaj ntau qhov ua tau zoo ntawm tus nqi. Txawm hais tias tus nqe ntawm cov khoom ua npuas polyurethane ua npuas ntau dua li lwm cov ntaub ntawv tsoos rwb thaiv tsev, tus nqi nce siab yuav raug tshem tawm los ntawm kev txo qis hauv cov nqi cua sov thiab cua txias.
