Ru tsev rwb thaiv tsev - cov ntaub ntawv uas xaiv

Ua ntej yuav pib cov rwb thaiv tsev ntawm lub-ru tsev, koj yuav tsum kom huv si xyuas ntau yam ntaub ntawv siv raws li rwb thaiv tsev ntawm lub-ru tsev, yuav tsum paub qhov zoo, cov disadvantages, raws li zoo raws li lawv lub teb ntawm daim ntawv thov. Ua tus xaiv txoj kev yuav pab tau koj stuff no tsab xov xwm los ntawm tshuaj ntsuam uas koj tsis yuav tsum sau nyob rau hauv Internet nrhiav xyaw cov lus nug txog dab tsi insulate lub-ru tsev.

Hnub no lub lag luam muaj lub sij hawm rau ib tug lossis loj xaiv ntawm insulating cov ntaub ntawv. Cov feem ntau sawv daws yuav yog: polystyrene thiab pob zeb wool, ua npuas ncauj iav, aerated qhob thiab txhav iav-fiber daim hlau. Cia peb xub xyuas txhua yam ntawm cov tsiaj.

Mineral wool, los yog es, lev thiab lub phaj ntawm nws, yog hnub no lub feem ntau ntau hom. Thermal rwb thaiv tsev ntawm lub ru tsev nrog mineral wool yuav rightly xam tau tias yog qhov zoo tshaj plaws tshuaj rau qhov teeb meem no. Txij li thaum nws muaj ib tug uas tsis muaj coefficient ntawm thermal conductivity (ntawm 0,032 mus 0,045 W / m × K), zoo vapor permeability, suab rwb thaiv tsev, durability (txog 50 xyoo) thiab elasticity. Tsis tas li ntawd, nws tsis yog kiag li dej haum thiab nws muaj ib tug high kuj mus txhua yam kev puas tsuaj. Thiab qhov tseem ceeb tshaj feature ntawm mineral wool - yog hais tias nws muaj ib tug uas tsis muaj flammability.

Yuav luag tib yam ntxwv thiab iav, txawm hais tias ib tug ntau ntau dej haum thiab dej vapor kis tau tus mob npaum li cas yog ntau qis. Yog xav tau tus raug tib yam li ntawm mineral wool, nws yog ua tau rau insulate lub-ru tsev pob zeb wool, vim hais tias ntawm nws cov khoom, nws yog heev uas zoo sib xws rau lub zog ntawm cov mineral.

Ru Rwb thaiv tsev extruded polystyrene ua npuas ncauj tej zaum yuav hu ua kuj yog ib tug zoo xaiv. Nws muaj ib tug uas tsis muaj thermal conductivity (0.02 rau 0,035 W / m × K), ib tug me me qhov hnyav thiab, tseem ceeb tshaj, kuj tsis tshua muaj nqi. Ntxiv rau nws muaj pes tsawg leeg tshwj xeeb tshuaj additive ua rau nws retardant thiab nws tus kheej-extinguishing khoom. Muaj kuj tsis zoo rau no hom ntawm rwb thaiv tsev, piv txwv li, muaj ib tug heev tsawg pa dej permeability hais tias thaum zoo mounted cua tej zaum yuav ua rau muaj zog av noo qab nthab qauv. Tsis tas li ntawd, polystyrene muaj tsawg elasticity thiab siab elasticity uas tsis pub nws siv nyob rau hauv thiaj li hu ua "vov tsev ncuav qab zib" rau lub installation ntawm ib tug complex ru tsev configurations.

Nyob rau lub hauv paus ntawm foamed yas, muaj yog ib yam zoo ntawm cov khoom, uas feem ntau ua rwb thaiv tsev ntawm lub ru tsev - ib tug polyurethane ua npuas ncauj. Nws zoo yam ntxwv yog cov nram qab no: nce kuj mus corrosive ib puag ncig, uas nws kim heev kev khiav hauj lwm ntau yam kub (los ntawm -180 mus +250 ° C). Tsis zoo - yog rhiab rau nyiaj tso ncaj tshav ntuj, vim hais tias ntawm yog dab tsi yog tsim nyog los tsim ib tug tiv thaiv txheej. Qhov no zoo ntawm cov ntaub ntawv uas tso cai rau ob lub tshuaj txhuam mechanically luag nws mus rau lub yam nto, thiab mus nqa tawm nws Txau. Nws tsuas yog lub ntsiab hom foamed polymer khoom, tseem muaj ntau lwm tus neeg.

Thermal rwb thaiv tsev ntawm lub ru tsev ntawm cov nyhuv microcameras, uas yog lawm ua tus sau nrog huab cua, tejzaum inorganic khoom uas yog hu ua cellular qhob. Yog, ntawm chav kawm, tsis muaj kev ua xyem xyav yuav ntaus nqi rau "nag hmo lub hnub." Tab sis txoj kev siv cov organic fiber rwb thaiv tsev, uas yog raws li nyob rau hauv cork, nws yog koj nyob ze-lub sij hawm Outlook ntawm qhov kev siv technology. Tab sis niaj hnub no nws yog incredibly kim Library.
