Vaj huam sib luag sandwichCov kev daws teeb meem ua lub luag haujlwm tseem ceeb hauv kev khaws cia txias, cov chaw tsim khoom hlau, thiab cov chaw nres tsheb thauj khoom, qhov twg kev ua haujlwm rwb thaiv tsev thiab kev nyab xeeb hluav taws cuam tshuam ncaj qha rau cov nqi zog thiab kev ua haujlwm mus sij hawm ntev. Kev xaiv cov khoom siv zoo tsis yooj yim. Cov neeg cog lus EPC thiab cov neeg tsim khoom yuav tsum sib npaug kev ua raws li hluav taws, kev ua haujlwm thermal, thiab cov peev nyiaj ntawm qhov project. Ntawm ntau txoj kev xaiv, PIR thiab pob zeb wool tseem yog cov ntaub ntawv vaj huam sib luag rwb thaiv tsev siv dav tshaj plaws hauv kev tsim kho niaj hnub.
Txhua yam khoom siv muaj qhov zoo thiab qhov tsis zoo. Kev xaiv kom zoo nyob ntawm hom phiaj xwm, qhov yuav tsum tau ua kom muaj hluav taws kub, thiab tej yam ib puag ncig. Tsis txhob nug tias hom twg zoo dua, cov neeg txiav txim siab yuav tsum tsom mus rau qhov kev daws teeb meem twg haum rau phiaj xwm zoo tshaj plaws.
Kev Ua Haujlwm thiab Kev Ua Raws Cai ntawm Kev Nyab Xeeb Hluav Taws
Kev nyab xeeb hluav taws feem ntau yog qhov tseem ceeb tshaj plaws hauv cov haujlwm loj. Cov pob zeb wool muaj kev ua tau zoo hauv thaj chaw no. Ua ib yam khoom siv inorganic, nws ua tiav A1 kev faib tawm uas tsis kub hnyiab raws li cov qauv xws li EN 13501. Nws tsis hlawv lossis tso pa lom hauv cov xwm txheej hluav taws. Qhov no ua rau nws tsim nyog rau cov chaw muaj kev pheej hmoo siab xws li cov chaw khaws khoom txias, cov tsev muag tshuaj, thiab cov chaw tsim khoom loj. Hauv cov cheeb tsam xws li Russia thiab Northern Europe, cov kab ke kaw ntawm cov chaw khaws khoom lossis cov chaw tsim khoom feem ntau siv cov pob zeb wool sandwich panels vim tias lawv tuaj yeem muab ob qho tib si rwb thaiv tsev thiab kev tiv thaiv hluav taws.
PIR, ua cov khoom siv rwb thaiv tsev organic, muab kev tiv thaiv hluav taws tsawg dua li cov pob zeb wool. Nws feem ntau ua tau raws li B-s1, d0 lossis cov kev faib tawm zoo sib xws, nyob ntawm cov qauv thiab kev tsim qauv. Hauv cov xwm txheej hluav taws, nws tuaj yeem lwj thiab tso pa tawm. Vim li no, PIR insulated panels feem ntau xav tau cov kev ntsuas tiv thaiv hluav taws ntxiv. Cov no suav nrog cov teeb meem hluav taws, cov txheej tiv thaiv, lossis cov tshuab sprinkler kom ua tau raws li qhov project ua raws li.
Hauv kev xyaum ua haujlwm engineering tiag tiag, cov kev daws teeb meem sib xyaw yog qhov tshwm sim. Cov neeg cog lus feem ntau muab cov PIR panels nrog cov pob zeb wool hluav taws thaiv kom sib npaug ntawm kev rwb thaiv tsev thiab kev nyab xeeb hluav taws. Txoj hauv kev no txhim kho kev ua raws li txoj cai thaum ua kom lub zog ua haujlwm tau zoo. Cov tswv yim tsim hluav taws kom meej thiab kev koom ua ke ntawm lub kaw lus yog qhov tseem ceeb rau kev pom zoo thiab kev pov hwm.
Kev Ua Haujlwm Thermal thiab Cov Xwm Txheej ntawm Daim Ntawv Thov
Kev ua tau zoo ntawm cov cua sov yog lwm qhov tseem ceeb hauv kev xaiv cov vaj huam sib luag sandwich. PIR muaj cov cua sov conductivity qis, feem ntau nyob ib puag ncig 0.022–0.024 W/(m·K). Qhov no tso cai rau cov vaj huam sib luag nyias dua rau tib lub hom phiaj rwb thaiv tsev. Nws pab txo kev siv cov khoom siv thiab ua kom qhov chaw sab hauv siab tshaj plaws, uas yog qhov tseem ceeb hauv cov chaw txias thiab cov chaw khaws khoom kub.
Cov vaj huam sib luag pob zeb wool qhia tau tias muaj kev ua tau zoo dua ntawm cov cua sov, feem ntau ntawm 0.036–0.040 W/(m·K). Qhov no txhais tau tias xav tau cov phab ntsa tuab dua kom ncav cuag tib theem rwb thaiv tsev. Txawm li cas los xij, cov pob zeb wool ua tau zoo hauv qhov kub siab thiab tswj tau qhov loj me ruaj khov dhau sijhawm. Nws kuj muab cov rwb thaiv tsev zoo thiab tiv taus cov chaw ua haujlwm hnyav.
Yuav tsum xav txog kev ua haujlwm ntawm cov dej noo. PIR muaj cov qauv kaw-cell uas tiv taus kev nkag mus rau hauv dej noo. Cov pob zeb wool xav tau kev sib khi zoo thiab cov pa dej thaiv kom tswj tau nws cov kev ua haujlwm hauv cov huab cua noo. Yog li ntawd, kev tsim qauv project yuav tsum suav nrog lub kaw lus ua tiav ntawm lub tsev es tsis txhob tsom mus rau cov ntaub ntawv ib leeg.
Ib lub tswv yim ua vaj huam sib luag sandwich panel tshaj lij tsis yog siv ib yam khoom xwb. Nws muab kev nyab xeeb hluav taws, lub hom phiaj thermal, thiab cov kev txwv ntawm qhov project ua ke rau hauv ib qho kev daws teeb meem. Los ntawm kev siv cov vaj huam sib luag insulated lossis cov vaj huam sib luag composite hauv txoj kev teeb tsa, cov neeg cog lus tuaj yeem ua tiav ob qho tib si kev ua raws li txoj cai thiab kev ua haujlwm zoo. Txoj hauv kev no txo qhov kev pheej hmoo, tswj tus nqi, thiab txhawb nqa kev ua tiav ntawm qhov project mus sij hawm ntev.
