Ua ntej koj pib rwb thaiv tsev ru tsev, koj yuav tsum tau ua tib zoo kawm txhua yam ntawm cov ntaub ntawv uas siv los ua cov rwb thaiv tsev ru tsev, paub qhov zoo, qhov tsis zoo, nrog rau lawv cov peev txheej. Cov ntaub ntawv hauv tsab xov xwm no yuav pab koj xaiv txoj cai, tom qab kawm uas koj yuav tsis tas yuav nkag mus rau cov lus nug hauv Is Taws Nem tshawb fawb xyaw txog kev thaiv lub ru tsev.
Hnub no lub khw muab kev xaiv loj ntawm cov ntaub ntawv rwb thaiv tsev thermal. Feem ntau ntawm lawv yog: polystyrene ua npuas ncauj thiab ntxhia wool board, foamed iav, cellular qhob thiab rigid fiberglass board. Cia peb nyob luv luv ntawm txhua yam ntawm no.
Mineral wool, lossis theej, ib daim lev thiab cov nplais los ntawm nws, niaj hnub no yog hom ntau tshaj plaws. Rwb thaiv tsev nrog cov ntxhia wool tuaj yeem raug suav hais tias yog qhov kev daws teeb meem zoo tshaj plaws rau qhov teeb meem no. Txij li thaum nws muaj ib tug tsawg coefficient ntawm thermal conductivity (los ntawm 0.032 mus rau 0.045 W / m × K), zoo vapor permeability, suab rwb thaiv tsev, durability (kwv yees li 50 xyoo) thiab elasticity. Nws kuj tseem tsis muaj dej nqus dej thiab muaj kev tiv thaiv siab rau kev puas tsuaj. Thiab cov cuab yeej tseem ceeb tshaj plaws ntawm cov ntxhia wool yog qhov ntawdNws muaj cov nplaim taws tsawg.
Cov iav ntaub plaub yuav luag zoo ib yam, txawm hais tias kev nqus dej ntau dua thiab vapor permeability qis dua. Txhawm rau kom tau txais cov txiaj ntsig zoo ib yam nrog cov ntaub plaub ntxhia, koj tuaj yeem thaiv lub ru tsev nrog pob zeb ntaub plaub, vim nws cov khoom zoo ib yam li cov ntaub plaub ntxhia.
Lub tsev rwb thaiv tsev nrog extruded polystyrene ua npuas ncauj kuj tseem hu ua qhov kev xaiv zoo. Nws muaj cov thermal conductivity tsawg (los ntawm 0.02 txog 0.035 W / m × K), qhov hnyav thiab qhov tseem ceeb, tus nqi qis. Tshwj xeeb tshuaj additives ntxiv rau nws muaj pes tsawg leeg ua rau nws ib tug nplaim-retardant thiab nws tus kheej-extinguishing khoom. Kuj tseem muaj qhov tsis zoo ntawm cov rwb thaiv tsev zoo li no, piv txwv li, muaj qhov tsis tshua muaj vapor permeability, uas, yog tias qhov cua tsis tau teeb tsa kom raug, tuaj yeem ua rau muaj av noo ntau ntxiv ntawm lub qab nthab ntawm cov qauv. Tsis tas li ntawd, nthuav polystyrene muaj elasticity tsawg thiab siab elasticity, uas ua rau nws tsis yooj yim sua kom siv nws nyob rau hauv lub thiaj li hu ua "ru tsev ncuav qab zib" rau mounting complex ru tsev configurations.
Rau lub hauv paus ntawm cov yas foamed, muaj lwm yam khoom siv uas feem ntau siv rau lub ru tsev rwb thaiv tsev - qhov no yog polyurethane ua npuas ncauj. Nws cov yam ntxwv zoo suav nrog cov hauv qab no: nce kev tiv thaiv rau qhov chaw nruj, kev ua haujlwm kub loj (ntawm -180 txog +250 ° C). Qhov tsis zoo yog qhov rhiab heev rau lub hnub ci ncaj qha, uas yuav tsum tau siv cov txheej txheem tiv thaiv. Cov khoom siv no tso cai rau ob qho tib si lo, mechanically kho nws mus rau qhov xav tau, thiab txau nws. Cov no tsuas yog hom ua npuas ncauj tseem ceeb xwb, muaj ntau yam ntxiv.
Rwb thaiv tsev ntawm lub ru tsev nrog cov nyhuv ntawm micro-chambers uas tau ntim nrog huab cua, tejzaum nws yog cov khoom siv tsis zoo hu ua cellular pob zeb. Yog lawm, tau kawg, qhov no tuaj yeem ua tsis tau raws li "yav tas los". Tab sis kev siv cov organic fiber ntau rwb thaiv tsev, uas yog raws li cork chips, twb yog qhov ze tshaj plaws rau kev tsim kho technology. Tab sis hnub no nws yog qhov zoo siab heev.
