Lub tshuab nqus tsev rwb thaiv tsev (VIP) yog ib qho ultra-thin thermal barrier tivthaiv tsim los ntawm kev khiav tawm cov khoom siv nanoporous-feem ntau compressed fumed silica los yog ultra-fine iav fiber ntau-hauv lub hermetically kub-sealed, ntau txheej high-barrier hnab ntawv, ua tiav ib qho chaw nruab nrab ntawm 30 0.000 as per thermal conductivity. W/(m·K). Los ntawm kev khiav hauj lwm ntawm qhov siab tshaj plaws hauv qab 1 txog 5 mbar (hPa), lub tshuab nqus tsev rwb thaiv tsev thaiv cov roj convection thiab molecular conduction nkaus, muab tsib mus rau yim npaug ntawm insulating thermal resistance (R-tus nqi ib nti) ntawm cov pa polyurethane (PU) ua npuas ncauj, nthuav polystyrene (EPS), los yog pob zeb ntaub plaub.
Nyob rau hauv qhov chaw tswj qhov kub thiab txias-tswj logistics, architectural tsev hnab ntawv, thiab cov khoom siv tub yees, cov khoom siv hluav taws xob zoo heev nyiag cov khoom siv sab hauv thiab qhia qhov hnyav hnyav. Kev sib xyaw ua ke ntawm 15 txog 25 hli lub tshuab nqus tsev tso cai rau cov kws ua haujlwm ua kom zoo rau cov thermal tsis kam ntawm 100 mus rau 150 hli cov qauv ua npuas ncauj rwb thaiv tsev, nthuav cov ntim ntim txog li 60% thaum tuav lub hom phiaj kub tuav rau ntau tshaj 120 teev. Txawm li cas los xij, VIP kev koom ua ke yuav tsum muaj cov txheej txheem tiv thaiv kev sib tsoo, kev tswj xyuas thermal ntug bridging, thiab cov tseem ceeb ntawm kev ua kom ntev ntev. Cov kev qhia no qhia txog cov tub ntxhais kawm physics, barrier zaj duab xis engineering, txias saw tsim cov cai, thiab cov qauv kev xa khoom ncaj qha los ntawm peb lub Hoobkas hauv Suav teb.
Anatomy ntawm High-Barrier VIP: Cov Khoom Siv Core & Lub hnab ntawv Physics
Thermal kev ua tau zoo thiab lub neej ua haujlwm ntev yog nyob ntawm kev sib cuam tshuam ntawm cov tub ntxhais hauv porosity thiab lub hnab ntawv roj permeation tsis kam:
Cov khoom siv tseem ceeb xaiv: Fumed Silica vs. Fiberglass:
Fumed Silica Core (Long-Life Standard):Ua los ntawm amorphous silicon dioxide nanoparticles nrog pore diameters nruab nrab ntawm 20 mus rau 30 nanometers. Vim hais tias cov qauv pore me dua qhov txhais tau tias tsis muaj txoj hauv kev ntawm huab cua, fumed silica panels khaws cov khoom muaj zog (kwv yees li 0.020 W / (m·K)) txawm tias huab cua tsis sib haum xeeb tshwm sim. Nrog kev sib xyaw tshuaj desiccant getters, fumed silica VIPs tswj lub tshuab nqus tsev ruaj khov rau 30 txog 50 xyoo, ua rau lawv tus qauv tsim nyog rau lub tsev facades thiab architectural retrofits.
Pre-formed Fiberglass Core (Ultra-Low Initial Conductivity):Muab cov thermal conductivity qis dua (0.0025 txog 0.0035 W / (m·K)) thiab tus nqi pheej yig. Txawm li cas los xij, fiberglass pores ntsuas 1 txog 10 microns; ib qho micro-leakage ua rau lub tshuab nqus tsev vacuum tam sim ntawd. Fiberglass panels xav tau cov khoom siv hlau hnyav thiab feem ntau xa mus rau hauv lub voj voog luv luv lub thawv thauj khoom txias thiab cov khoom siv tub yees hauv tsev.
High-Barrier Film Envelopes:Txhawm rau kom muaj kev ntseeg siab ntawm lub tshuab nqus tsev ntau xyoo, cov tub ntxhais yog qhwv hauv cov laminate tshwj xeeb:
Metallized Polyethylene Terephthalate (MF-PET):Multi-layered polymer films sputtered nrog nano-thin aluminium txheej, txo cov thermal bridging nyob ib ncig ntawm lub vaj huam sib luag perimeter flanges thaum txwv cov dej vapor kis tus nqi (WVTR < 0.001 g / m2 · hnub).
Nruam Aluminium Ntawv Nyiaj Laminates (AF):Incorporates ib tug ultra-ntshiab 6 mus rau 9 micron txhuas ntawv ci txheej rau xoom gas permeability, teev rau high humidity los yog submerged txias compartments.
Kev yuav khoom ncaj qha los ntawm kev lees paublub tshuab nqus tsev rwb thaiv tsev panelsmanufacturers xyuas kom muaj ntawv pov thawj lub hnab ntawv sealing thiab mus sij hawm ntev kev laus stability.
