1. Rigid polyurethane muaj cov thermal conductivity tsawg thiab kev ua haujlwm zoo thermal. Thaum qhov ntom ntom ntawm polyurethane yog 35 ~ 4 0kg / m3, thermal conductivity tsuas yog 0.018 ~ 0.024w / (mk), uas yog ib nrab ntawm EPS. Nws yog qhov tsawg thermal conductivity ntawm tag nrho cov khoom siv thermal rwb thaiv tsev tam sim no.
2. Rigid polyurethane muaj cov dej tsis zoo thiab tsis muaj dej. Qhov sib piv ntawm cov xov tooj kaw ntawm nruj polyurethane yog ntau tshaj 90 feem pua, uas yog cov khoom siv hydrophobic. Nws yuav tsis ua kom cov thermal conductivity vim yog nqus noo noo, thiab phab ntsa yuav tsis xau.
3. Rigid polyurethane yog fireproof, nplaim retardant thiab kub resistant. Tom qab ntxiv cov nplaim hluav taws kub, polyurethane yog cov nplaim hluav taws tua tus kheej. Nws qhov taw tes softening tuaj yeem ncav cuag ntau tshaj 250 degree, thiab nws yuav decompose tsuas yog nyob rau qhov kub siab dua. Tsis tas li ntawd, polyurethane yuav tsim cov pa roj carbon deposits ntawm nws cov npuas dej thaum hlawv, uas yuav pab cais cov npuas dej hauv qab no. Nws tuaj yeem tiv thaiv cov nplaim taws. Ntxiv mus, polyurethane tsis tsim cov pa phem ntawm qhov kub thiab txias.
4. Vim qhov kev ua tau zoo ntawm kev rwb thaiv tsev ntawm cov ntawv polyurethane, lub thickness ntawm lub tsev sab nrauv tuaj yeem raug txo kom tsawg raws li qhov yuav tsum tau ua ntawm cov rwb thaiv tsev kub, yog li ua rau thaj chaw siv sab hauv.
5. Nws muaj zog deformation tsis kam, tsis yooj yim rau tawg, thiab qhov kawg yog ruaj khov thiab nyab xeeb.
6. Cov qauv porosity ntawm cov khoom siv polyurethane yog qhov ruaj khov, uas yog ib qho ntawm cov qauv kaw. Nws tsis tsuas yog muaj kev ua haujlwm zoo thermal rwb thaiv tsev, tab sis kuj muaj qhov zoo khov-thaw ua haujlwm thiab lub suab nqus. Qhov nruab nrab ntawm lub neej ntawm cov khoom ua npuas ncauj polyurethane rwb thaiv tsev tuaj yeem ncav cuag ntau tshaj 30 xyoo nyob rau hauv kev siv thiab kev saib xyuas. Nyob rau hauv cov kev pab cuam ib txwm nyob rau hauv lub neej kev pab cuam ntawm cov qauv, cov qauv yuav tsis puas nyob rau hauv qhuav, ntub dej los yog electrochemical corrosion, raws li zoo raws li kev loj hlob ntawm kab, fungi los yog algae, los yog vim kev puas tsuaj ntawm nas thiab lwm yam sab nraud. yam.
7. Kev ua tau zoo ntawm tus nqi siab. Txawm hais tias chav tsev tus nqi ntawm polyurethane ua npuas ncauj yog siab dua li ntawm lwm cov khoom siv rwb thaiv tsev, tus nqi nce yuav raug them los ntawm kev txo cov nqi cua sov thiab cua txias.
● Ntau qhov tshwj xeeb thiab ntau yam, chav ntsuas qhov hnyav: ({{0}}kg/m3); Ntev: (0.5m-4 m); Qhov dav: (0.5m-1.2m); Thickness ntau: (20mm - 200mm).
● Qhov raug txiav yog siab, thiab qhov ua yuam kev thickness yog ± 0.5mm, yog li xyuas kom meej qhov flatness ntawm cov khoom tiav lawm.
● Cov npuas yog zoo thiab ntom nrog txawm npuas.
● Lub teeb chav tsev qhov hnyav, uas tuaj yeem txo qhov hnyav ntawm tus kheej ntawm cov khoom tiav los ntawm 30-60 feem pua piv nrog cov khoom siv tsoos.
● Nrog lub zog compressive siab, nws tuaj yeem tiv taus lub siab loj thaum lub sij hawm tsim cov khoom tiav.
● Nws yog qhov yooj yim rau kev tshuaj xyuas zoo. Txij li thaum daim tawv nqaij ib ncig raug tshem tawm hauv cov txheej txheem txiav, qhov zoo ntawm cov phaj yog qhov tseeb ntawm ib nrais muag, kom ntseeg tau tias cov thermal rwb thaiv tsev nyhuv ntawm cov khoom tiav. Lub thickness tuaj yeem tsim thiab ua tiav raws li cov neeg siv khoom xav tau.
