Ob leegPIR vaj huam sib luagthiabcov vaj huam sib luag cia khoom txiasxa mus rau cov ntaub ntawv rwb thaiv tsev ua haujlwm siab. Qhov sib txawv tseem ceeb yog nyob rau hauv cov khoom siv thiab kev ua tau zoo: PIR panels (polyisocyanurate panels) yog kev hloov kho dua tshiab ntawm polyurethane (PUR), muaj kev tiv thaiv hluav taws zoo heev, tiv taus kub siab (txog li 200 ℃ thiab siab dua), thiab nqus dej tsawg (qis dua PUR). Lawv yog thawj qhov kev xaiv rau kev tsim cov chaw cia khoom txias uas xav tau siab, cov chaw ua zaub mov, thiab lwm yam tsev. "Cov vaj huam sib luag cia khoom txias" feem ntau yog hais txog cov ntaub ntawv rwb thaiv tsev siv hauv kev cia khoom txias, uas tuaj yeem yog PIR, PUR, XPS, thiab lwm yam. Vim nws qhov kev ua tau zoo tag nrho, PIR tau dhau los ua lub hauv paus ntawm cov khoom siv niaj hnub high-end.txias cia panels.
PIR (Polyisocyanurate) Cov yam ntxwv tseem ceeb ntawm pawg thawj coj saib xyuas:
Kev Tiv Thaiv Hluav Taws Zoo Tshaj Plaws: Los ntawm kev nce qhov concentration ntawm isocyanate ring, nws qhov kev tiv thaiv hluav taws ntau dua li ntawm PUR vaj huam sib luag, ua tiav qhov ntsuas hluav taws B1.
Kev Rwb Thaiv Kub Zoo Tshaj Plaws: Kev ua tau zoo ntawm cov cua sov tsawg heev (≤0.023 W/mK), ua rau muaj kev rwb thaiv tsev zoo.
Kev Kub Siab Tsis kam: Kev siv mus sij hawm ntev tuaj yeem tiv taus qhov kub siab tshaj 150 ℃, txawm tias txog li 205 ℃, haum rau qhov chaw kub siab.
Kev Nqus Dej Tsawg: Tus nqi nqus dej tsawg heev, tiv thaiv kom tsis txhob muaj dej noo nkag thiab tswj tau kev ua haujlwm rwb thaiv tsev.
Lub Zog Muaj Zog: Kev ceev ceev, ruaj khov, txhim kho lub zog ntawm lub tsev.
Ib puag ncig zoo: CFC-dawb.
Cov Vaj Huam Sib Luag Cia Khoom Txias:
Lub Tswv Yim Dav Dav: Hais txog txhua lub vaj huam sib luag sandwich siv hauv kev tsim cov chaw cia khoom txias; lub luag haujlwm tseem ceeb yog kev rwb thaiv tsev thiab kev kaw.
Cov Khoom Siv Sib Txawv: Ntxiv rau lub rooj tsavxwm PIR tseem ceeb, nws kuj suav nrog PUR (polyurethane), XPS (extruded polystyrene), thiab lwm yam.
Kev Ua Tau Zoo: Cov ntaub ntawv tseem ceeb sib txawv raug xaiv raws li qhov kub thiab txias xav tau ntawm qhov chaw cia khoom txias.
PIR Panels vs. Cov PUR Txias Cia Khoom Siv
Kev Tiv Thaiv Hluav Taws: PIR > PUR
Kub tsis kam: PIR (-196 ℃ + 205 ℃) > PUR (-185 ℃ + 110 ℃)
Kev Nqus Dej: PIR (<1%)< PUR (2.5% ~ 3%)
Qhov Ceev: PIR (40-45 kg/m³) > PUR (38-40 kg/m³)
Tus nqi: PIR feem ntau siab dua PUR.
Kev Txheeb Xyuas
Cov vaj huam sib luag PIR yog cov sawv cev ntawm cov vaj huam sib luag cia khoom txias ua haujlwm tau zoo, tshwj xeeb tshaj yog tsim rau cov khoom siv niaj hnub no thiab kev lag luam ua zaub mov nrog cov kev cai nruj rau kev tiv taus hluav taws, tiv taus kub siab, thiab nqus dej tsawg. Lawv muab cov kev daws teeb meem rwb thaiv tsev zoo dua li cov vaj huam sib luag PU chav txias ib txwm muaj.
