XPS ua npuas ncauj pawg thawj coj saib (extruded polystyrene board) muaj kev ua tau zoo thermal rwb thaiv tsev, uas yog feem ntau xav txog hauv qab no:
1. Tsawg thermal conductivity
Lub thermal conductivity ntawm XPS ua npuas ncauj board yog qhov tsawg heev, feem ntau yog nruab nrab ntawm {{0}}.024 ~ 0.035 W / (m·K), uas txhais tau hais tias nws tuaj yeem tiv thaiv kev hloov ntawm tshav kub. Cov cuab yeej no muab XPS ua npuas ncauj board muaj txiaj ntsig zoo hauv thaj chaw ntawm rwb thaiv tsev, ua kom muaj qhov kub thiab txias hauv tsev thiab txo kev siv hluav taws xob.
2. Siab kaw cell piv
Qhov kaw ntawm tes ntawm XPS ua npuas ncauj board yog siab li ntau tshaj 99%, thiab lub tshuab nqus tsev txuas ntxiv yog tsim rau hauv. Cov qauv no zoo heev txo cov channel rau huab cua ntws thiab hloov hluav taws xob, kom ntseeg tau tias kev ua haujlwm ntev thiab ruaj khov thermal rwb thaiv tsev. Nyob rau hauv sib piv, lwm cov ntaub ntawv rwb thaiv tsev, xws li foamed polyurethane, muaj ib tug qis cell kaw tus nqi, yog li XPS ua npuas ncauj board muaj ib tug zoo dua nyob rau hauv cov nqe lus ntawm thermal rwb thaiv tsev nyhuv.
3. Kev txuag hluav taws xob ruaj khov
XPS ua npuas ncauj board tuaj yeem tsis tsuas yog tswj tau ntau dua 85% cov nyhuv rwb thaiv tsev nyob rau hauv cov av noo ib puag ncig (xws li 70% txheeb ze av noo), tab sis kuj nws cov thermal rwb thaiv tsev kev ua tau zoo tseem ruaj khov tom qab siv mus ntev. Qhov no yog vim nws zoo heev durability thiab ruaj khov tshuaj. Kev sim tau pom tias qhov kev ua haujlwm thermal rwb thaiv tsev ntawm XPS npuas board tseem muaj siab heev tom qab ntau lub voj voog khov-thaw, uas qhia tau zoo heev khov-thaw tsis kam.
4. Kev sib piv ntawm thermal rwb thaiv tsev nyhuv
Kev xyaum tau ua pov thawj tias cov thermal rwb thaiv tsev ntawm XPS ua npuas ncauj yog qhov tseem ceeb heev. Piv txwv li, 20 hli tuab XPS extruded rwb thaiv tsev board yog sib npaug rau 50 hli tuab nthuav polystyrene, los yog 120 hli tuab cement perlite. Qhov no yog ntxiv pov thawj ntawm kev ua tau zoo ntawm XPS ua npuas ncauj pawg thawj coj saib ntawm kev ua haujlwm thermal rwb thaiv tsev.
5. Kev siv ntau yam
Vim nws cov thermal rwb thaiv tsev zoo heev, XPS ua npuas ncauj board yog dav siv nyob rau hauv ntau lub sij hawm uas yuav tsum tau thermal rwb thaiv tsev, xws li lub tsev ru tsev rwb thaiv tsev, steel qauv vov tsev, lub tsev phab ntsa rwb thaiv tsev, lub tsev av noo noo retention, square av te heave tswj, central cua txias. qhov cua tshuab, geothermal engineering, txoj kev loj, tshav dav hlau khiav, qhov txias txias thiab lub tsheb sab hauv kho kom zoo nkauj rwb thaiv tsev thiab lwm yam.
