Sab nrauv phab ntsa rwb thaiv tsev kho kom zoo nkauj board yog muab faib ua cov khoom siv organic, cov ntaub ntawv inorganic thiab cov ntaub ntawv sib xyaw raws li cov khoom siv. Raws li kev ua haujlwm ntawm cov ntaub ntawv rwb thaiv tsev, tus nqi kuj txawv.
Lub tshuab nqus tsev rwb thaiv tsev rau sab nrauv phab ntsa rwb thaiv tsev zoo nkauj board, thermal conductivity 0.008w/(mk)
Thawj yog pom tseeb tias lub tshuab nqus tsev rwb thaiv tsev phaj. Qhov no yog ib qho zoo thermal rwb thaiv tsev board ua los ntawm inorganic fiber core cov ntaub ntawv, siab tiv thaiv zaj duab xis nqus encapsulation tshuab thiab tshwj xeeb interface mortar.
Cua muaj qhov thermal conductivity ntawm 0.023 w/(M^K). Txhawm rau kom tau txais cov thermal conductivity qis dua li huab cua, tsuas yog lub tshuab nqus tsev muaj. Yog li ntawd, lub thermal conductivity ntawm lub tshuab nqus tsev rwb thaiv tsev yog undoubtedly qis dua cov rwb thaiv tsev uas twb muaj lawm. Qhov zoo dua yog tias txhua yam khoom siv rwb thaiv tsev nrog cov khoom sib txawv tuaj yeem tsis quav ntsej. Tab sis daim ntawv kuj muaj qhov tsis txaus ntshai. Piv txwv li, lub tshuab nqus tsev yog qhov nyuaj rau kev tswj xyuas. Yog tias muaj kev puas tsuaj tshwm sim, qhov kev ua haujlwm rwb thaiv tsev ntawm daim ntawv yuav raug txo qis.
Vim yog cov txheej txheem kev tsim kho tam sim no, cov laug cam tau sewn ntau dhau, uas ua rau muaj kev pheej hmoo loj ntawm kev sib xyaw ua ke. Tsis tas li ntawd, qhov smoothness ntawm kev tsim kho yog qhov nyuaj rau kev tswj, thiab kev pheej hmoo ntawm cov txheej txheem plaster nyias ntog yog qhov zoo heev. Tam sim no, tus nqi tsim khoom ntawm cov khoom no yog siab, qhov zoo ntawm cov nqi ua haujlwm tsis pom tseeb. Yog tias tus nqi ntawm cov khoom no raug txo qis dua, nws tuaj yeem txiav txim siab tau siv rau lub sam thiaj panels los tiv thaiv kev siv cov choj txias. Cov txiaj ntsig simulation qhia tau tias ntev npaum li lub sam thiaj yog 500mm dav, nws tuaj yeem ua lub luag haujlwm ntawm insulating tus choj thermal. Yog li ntawd, lub sam thiaj tsis xav tau thaj tsam loj ntawm 3cm tuab pawg thawj coj saib, thiab lub tshuab nqus tsev rwb thaiv tsev ntawm 8mm tuab tsuas yog 500mm dav, uas txuag kev siv ntau heev.
Airgel rau sab nrauv phab ntsa rwb thaiv tsev hniav board, thermal conductivity 0.02w/(mk)
Cov khoom siv Airgel tau raug hu ua lub ntiaj teb lub teeb tshaj plaws. Nano silica airgel yog cov khoom tseem ceeb, los ntawm cov txheej txheem tshwj xeeb sib xyaw, muaj qhov kub thiab txias, tsis tshua muaj thermal conductivity, tsis tshua muaj siab, siab zog, kev tiv thaiv ib puag ncig, tsis muaj dej tsis zoo thiab lwm yam kev ua tau zoo, yog qhov tseem ceeb ntawm cov khoom siv hluav taws xob hluav taws xob hauv metallurgy. , tshuaj lom neeg kev lag luam, kev tiv thaiv teb chaws, aerospace thiab lwm yam kev lag luam.
Cov khoom sib xyaw ua ke thermal rwb thaiv tsev thiab hluav taws kub tsis kam, ua rau nws cov khoom tsis tshua muaj, tab sis nws tsis yog siv dav hauv kev tsim kho engineering hauv Europe. Sab nrauv phab ntsa rwb thaiv tsev dai kom zoo nkauj board manufacturers xav tias tus nqi ntawm cov khoom yog siab dhau lawm, rau lub ntsiab Cheebtsam ntawm lub sab nraud thermal rwb thaiv tsev system los tiv thaiv lub txias thiab cua sov voj voog, tab sis kuj yuav tsum tau tiv thaiv ntau yam kev ntsuam xyuas, tam sim no tsis muaj engineering piv txwv. los ua pov thawj qhov kev ntseeg ntawm sab nrauv phab ntsa rwb thaiv tsev siv. Raws li lub teb chaws tej yam kev mob, cov ntaub ntawv airgel yuav dhau los ua cov khoom nyob rau hauv lub laboratory rau lub sij hawm ntev, thiab nws zoo nkaus li tsis yooj yim sua mus thov nyob rau hauv lub tshav pob ntawm engineering sab nrauv rwb thaiv tsev.
Ua npuas ncauj polyurethane panels rau sab nrauv rwb thaiv tsev zoo nkauj panels, thermal conductivity 0.024w/(mk)
Kev ua tau zoo ntawm cov khoom siv hluav taws xob ib leeg yog zoo dua li cov khoom siv hluav taws xob polyurethane. Raws li cov txheej txheem sib txawv, nws tau muab faib ua teb foamed polyurethane thiab Hoobkas ua ntej ua npuas ncauj polyurethane board.
Ua npuas ncauj polyurethane board yog raws li isocyanate txias, polyol (ua ke polyester los yog polyol) raws li lub ntsiab raw khoom ntxiv additives ntawm ob Cheebtsam, sab nrauv phab ntsa rwb thaiv tsev zoo nkauj board manufacturers uas yog los ntawm lub tshav pob kev tsim kho nrog rwb thaiv tsev thiab waterproof ua hauj lwm ntawm rigid foam khoom. .
Ua npuas ncauj polyurethane board muaj kev ncaj ncees zoo thiab tsis muaj dej, haum rau lub ru tsev rwb thaiv tsev thiab waterproof, hauv qab daus phab ntsa npog rwb thaiv tsev thiab waterproof, haum rau qhuav phab ntsa rwb thaiv tsev, yooj yim siv kev lag luam, ntau ua si lub luag hauj lwm ntawm kev tiv thaiv tshav kub. Ua npuas ncauj polyurethane board yog cov khoom lag luam derivative, nrog kev poob qis ntawm qhov ruaj khov, qhov txheeb ze ntawm polystyrene board tsis txawv ntau. Qee lub tuam txhab tau muab cov khoom sib xyaw polyurethane A-chav kawm phaj nrog ob-coated mortar thiab daim ntawv tshuaj ntsuam xyuas, uas nyuam qhuav dhau los ntawm ib lub sijhawm thiab tuaj yeem siv los ua cov khoom siv hluav taws xob. Yog tias cov qauv tshuaj xyuas hluav taws tshiab raug qhia, cov khoom siv yuav tsis raug pom zoo.
