PU Ntug Pob Zeb Wool Sandwich Panels

Cov vaj huam sib luag PU ntug pob zeb wool sandwich tau dhau los ua ib qho tseem ceeb hauv kev tsim kho niaj hnub no, sib npaug kev nyab xeeb hluav taws, kev siv hluav taws xob zoo, thiab kev ruaj khov. Cov vaj huam sib luag no muab cov pob zeb wool core nrog PU ntug sealing los daws cov teeb meem kev ua tau zoo uas cuam tshuam nrog cov vaj huam sib luag sandwich wool ib txwm muaj.

Nkag Siab Txog Pob Zeb Wool Sandwich Panels

Cov vaj huam sib luag sandwich wool muaj ib txheej ntawm cov pob zeb wool rwb thaiv tsev core uas muab tais rau ntawm ob lub hlau, feem ntau yog galvanized lossis xim-coated hlau. Cov pob zeb wool nws tus kheej yog tsim los ntawm cov pob zeb ntuj thiab cov khoom siv minerals uas yaj thiab spin ua cov fibers uas muab kev tiv thaiv hluav taws zoo heev thiab kev ua haujlwm thermal. Cov pob zeb wool core lub thermal conductivity feem ntau yog li ntawm 0.035–0.043 W / m·K.

Ib qho ntawm cov txiaj ntsig tseem ceeb tshaj plaws ntawm cov vaj huam sib luag pob zeb yog lawv qhov kev ua tau zoo hluav taws. Pob zeb wool yog cais ua cov khoom siv uas tsis kub hnyiab Chav Kawm A uas tiv taus qhov kub siab tshaj 1000 ° C yam tsis ua rau muaj hluav taws kub, ua rau nws tsim nyog rau cov qauv uas muaj cov kev cai nruj heev txog kev nyab xeeb hluav taws.

Ntxiv rau kev rwb thaiv tsev thermal, kev ua tau zoo ntawm cov pob zeb wool zoo dua li ntau lwm cov ntaub ntawv tseem ceeb. Nrog rau kev ua tau zoo ntawm kev rwb thaiv tsev suab nrov ncav cuag RW = 29–30 dB rau cov vaj huam sib luag nrog 120 kg / m³ density cores,cov vaj huam sib luag pob zeb woolpab tsim kom muaj kev nyob ntsiag to hauv cov chaw ua haujlwm thiab kev lag luam.

Kev sib tw ntawm Pob Zeb Wool Sandwich Panels

Txawm hais tias muaj cov zog no los, cov vaj huam sib luag sandwich wool kuj muaj teeb meem. Lawv cov qauv fibrous thiab qhov porosity ntuj tuaj yeem ua rau lawv yooj yim rau cov dej noo nkag mus yog tias cov npoo tsis raug kaw kom zoo.

Yog tias raug dej noo, cov pob zeb wool tuaj yeem nqus dej, uas ua rau cov nqi rwb thaiv tsev txo qis thiab yuav ua rau pwm loj hlob. Qhov kev txwv no txhawb kev txhim kho xws li kev kaw ntug thiab kev tsim cov pob qij txha zoo dua.

Dhau li ntawm qhov ntawd, cov vaj huam sib luag sandwich wool kuj muaj lwm yam tsis zoo. Piv txwv li, qhov hnyav dua piv rau qee lub cores ua npuas ncauj, ua rau cov khoom thauj thiab cov nqi thauj khoom nce ntxiv.

Feem ntau cov khoom siv hluav taws xob ua kom sov tau zoo dua li cov ua npuas ncauj kaw zoo li polyurethane. Qhov no txhais tau tias cov vaj huam sib luag tuab dua feem ntau xav tau kom ua tiav kev rwb thaiv tsev zoo sib xws.

Cov qhov tsis zoo no tsis ua rau tus nqi ntawm cov pob zeb wool panels tsis zoo, tab sis cov neeg tsim qauv thiab cov neeg ua vaj tse yuav tsum daws cov teeb meem no.

Cov Kev Dais Teeb Meem thiab Lub Luag Haujlwm ntawm PU Edge Sealing Technology

Txhawm rau daws cov kev txwv ntawm cov qauv pob zeb wool sandwich panels, cov chaw tsim khoom thiab cov engineers siv ntau yam kev daws teeb meem:

Kev txhim kho kev tsim qauv sib koom ua ke. Los ntawm kev teeb tsa cov hlau baffles rau ob sab ntawm lub vaj huam sib luag sandwich. Cov baffles thiab cov vaj huam sib luag tsim cov qauv sib xyaw ua ke los ntawm kev sib txuas ntawm tus nplaig-thiab-groove, txhim kho qhov nruj ntawm cov huab cua ntawm cov pob zeb wool core.

Siv polyurethane los kaw ntug. Siv PU rau ntawm ntug vaj huam sib luag ua ib qho thaiv uas txo cov dej noo nkag, cua xau, thiab hmoov av nkag mus. Qhov no kuj txo qhov thermal bridging thiab tiv thaiv lub pob zeb wool core los ntawm kev puas tsuaj rau ib puag ncig.

Cov txheej txheem no tuaj yeem daws cov teeb meem uas cov vaj huam sib luag pob zeb ib txwm ntsib, tab sis kuj muaj qhov sib txawv. Vim yog cov khoom siv lub cev ntawm cov khoom siv pob zeb pob zeb tseem ceeb, tseem muaj ntau qhov khoob hauv cov vaj huam sib luag pob zeb pob zeb sandwich nrog cov hlau baffles. Tshwj xeeb tshaj yog rau cov vaj huam sib luag pob zeb pob zeb, qhov tsis zoo no pom tseeb dua.

Cov ntaub ntawv kev lag luam ntawm PU ntug vaj huam sib luag qhia txog kev txhim kho uas ntsuas tau hauv cov ntsuas kev ua tau zoo. Piv txwv li, cov vaj huam sib luag pob zeb uas kaw ntug khaws cov nqi rwb thaiv suab ≥30 dB thiab Chav Kawm A qib hluav taws, thaum lub foob ntug tiv thaiv lub hauv paus ntawm cov dej noo thaum lub sijhawm ua haujlwm ntev.

Cov neeg ua vaj tse feem ntau muab cov tswv yim no ua ke nrog kev coj ua kom ruaj khov, xyuas kom meej tias cov vaj huam sib luag tau teeb tsa kom raug, kaw, thiab sib xyaw nrog cov teeb pom kev zoo thiab cov pa dej kom ua tau zoo tshaj plaws rau ntau xyoo ntawm kev siv.

PU Edge Rock Wool Sandwich Panels Ua Haujlwm Li Cas Thiab Lawv Cov Zoo Li Cas

PU ntug pob zeb wool sandwich panels sib txawv lawv tus kheej los ntawm kev tsim kho tshwj xeeb ntawm cov vaj huam sib luag tseem ceeb. Lub hauv paus qauv sib xyaw ua ke pob zeb wool nrog polyurethane ntug sealing khoom siv rau txhua ntug vaj huam sib luag. Polyurethane, paub txog kev nplaum siab thiab elasticity, tsim kev sib txuas ruaj khov ntawm cov tawv nqaij hlau thiab lub hauv paus rwb thaiv tsev, tiv thaiv cov cheeb tsam tsis muaj zog.

PU ntug ua haujlwm ntau yam tseem ceeb:

Kev tiv thaiv dej noo. PU ntug ua haujlwm ua lub foob hydrophobic uas tiv thaiv dej nkag mus. Pob zeb wool ib leeg yooj yim nqus dej noo, yog li polyurethane thaiv tau txo qhov kev pheej hmoo no.

Kev ua haujlwm thermal zoo dua. Los ntawm kev txo cov cua nkag thiab thermal bridging ntawm cov pob qij txha vaj huam sib luag, qhov kev tiv thaiv thermal tag nrho ntawm kev sib dhos tau txhim kho piv rau lwm txoj hauv kev tsis tau kaw.

Kev txhawb zog ntawm lub tshuab. Cov txheej txheem ntawm kev siv polyurethane los khi ntug tsis yog tsuas yog txhim kho qhov nruj ntawm cov khoom siv tseem ceeb xwb, tab sis kuj tseem ua kom lub pob zeb wool block ntawm sab muaj zog, txo qhov poob ntawm ntug. Lub foob ntug pab txhawb rau qhov ruaj khov ntawm lub vaj huam sib luag, pab tiv thaiv kev hloov pauv hauv qab kev thauj khoom thiab txhim kho kev tiv thaiv cua.

Cov yam ntxwv no txhawb nqa cov ntsuas kev ua tau zoo uas cov chaw tsim khoom hais. Piv txwv li, cov vaj huam sib luag nrog 100 hli lub plawv tuab feem ntau qhia cov nqi conductivity cua sov nyob ib puag ncig 0.41 W / m² · K, sib npaug ntawm kev rwb thaiv tsev nrog qhov hnyav ntawm cov qauv.

Piv nrog cov vaj huam sib luag pob zeb uas tsis muaj kev sib khi ntug, PU ntug vaj huam sib luag feem ntau muab lub neej ua haujlwm ntev dua, ntau dua 15 xyoo, txo cov teeb meem kev saib xyuas, thiab txhim kho kev tiv thaiv dej noo hauv cov chaw noo noo lossis ntug dej hiav txwv. Cov yam ntxwv no ua rau PU ntug vaj huam sib luag pob zeb sandwich tshwj xeeb tshaj yog haum rau cov chaw lag luam, cov tsev txias, tshav dav hlau, chaw ua si nawv, thiab cov chaw lag luam uas kev ua tau zoo mus sij hawm ntev thiab kev nyab xeeb yog qhov tseem ceeb.
