Hauv ntau qhov haujlwm engineering, cov ntaub ntawv rwb thaiv tsev yuav tsis yog qhov pom tseeb tshaj plaws, tab sis lawv feem ntau txiav txim siab qhov kev ua haujlwm ntawm lub cev. Los ntawm lub tsev facades mus rau cov kav dej thiab cov khoom siv hluav taws xob tshiab, qhov tuab, qhov hnyav, thiab kev ruaj ntseg ntawm cov txheej rwb thaiv tsev ncaj qha cuam tshuam rau qhov ua tau ntawm kev tsim. Nyob rau hauv xyoo tas los no, cov khoom hu ua "aerogel pam" tau nquag tshwm sim hauv cov ntawv thov no, rov txhais cov kev sib raug zoo ntawm "thinness" thiab "insulation."
Cov neeg uas ntsib airgel pam vov thawj zaug feem ntau xav tsis thoob los ntawm lawv cov tsos. Nws zoo nkaus li zoo li cov ntaub mos muag ntau dua li cov tsoos rwb thaiv tsev board. Txawm li cas los xij, nws yog qhov tseeb qhov "zoo li nyias" cov khoom uas tau hloov cov txheej txheem loj dua, bulkier rwb thaiv tsev hauv ntau qhov haujlwm.
Vim li cas "thinness" yog qhov tseem ceeb?
Hauv kev tsim rwb thaiv tsev ib txwm muaj, txoj hauv kev ncaj qha tshaj plaws los txhim kho thermal rwb thaiv tsev kev ua tau zoo yog "nce qhov tuab." Pob zeb wool, iav ntaub plaub, los yog cov ntaub ntawv ua npuas ncauj feem ntau xav tau ib qho tuab kom ua tau raws li cov qauv tsim. Txawm li cas los xij, hauv qhov tiag -cov haujlwm engineering hauv ntiaj teb, thickness tsis yog ib qho khoom kim heev.
Hauv kev kho dua tshiab ntawm cov tsev qub, qhov chaw sab nrauv phab ntsa yog txwv; nyob rau hauv densely npaj cov khoom siv, qhov chaw seem rau rwb thaiv tsev ntawm cov kav dej yog ua me; thiab hauv qee cov khoom siv mobile lossis modular, qhov hnyav kuj yog qhov tseem ceeb. Nws yog nyob rau hauv cov xwm txheej no uas qhov zoo ntawm cov pam pam airgel pib qhia - rau tib lub rwb thaiv tsev zoo, lawv xav tau tsawg dua thickness.
Qhov kev ua haujlwm thermal rwb thaiv tsev los ntawm qhov twg?
Lub hauv paus ntawm daim pam airgel tseem yog airgel nws tus kheej. Cov khoom no yog ntim nrog nanoscale pores, thiab huab cua nyob rau hauv cov chaw me me no, ua kom zoo cua sov convection yuav luag tsis yooj yim sua. Nyob rau tib lub sij hawm, lub moj khaum khoom nws tus kheej yog heev sparse, ho lengthening lub tshav kub conduction txoj kev.
Hauv kev siv cov tswv yim, airgel feem ntau yog ua ke nrog cov ntaub ntawv fiber ntau los ua ib daim pam hloov tau -zoo li cov qauv. Txoj kev sib xyaw no tsis tsuas yog khaws cov thermal rwb thaiv tsev ntawm airgel tab sis kuj daws nws qhov teeb meem brittleness, tso cai rau cov khoom txiav thiab khoov kom haum rau qhov chaw ntawm cov khoom siv complex - zoo li tus.
"thinner" txhais li cas?
"Thinness" tsis yog hais txog kev txuag chaw xwb. Hauv ntau qhov xwm txheej engineering, nws kuj txhais tau tias muaj kev hloov pauv hauv kev tsim kho.
Ib txheej txheej rwb thaiv tsev nyias yooj yim dua kom haum rau cov txheej txheem nyuaj, txo qhov sib txuas thiab qhov khoob, yog li txo qhov kev pheej hmoo ntawm thermal bridging. Rau cov khoom xws li cov kav dej thiab cov li qub, cov neeg ua haujlwm tsim kho tsis tas yuav ntxiv dag zog rau cov qauv tsim kom haum rau cov txheej txheem rwb thaiv tsev tuab, ua rau kev txhim kho kev tsim kho tag nrho.
Rau cov khoom siv uas yuav tsum tau saib xyuas tsis tu ncua, nyias nyias, cov ntaub ntawv rwb thaiv tsev yooj yim kuj yooj yim rau nruab thiab tshem tawm. Cov kev hloov me me no feem ntau txhais mus rau qhov sib txawv ntawm tus nqi tseem ceeb hauv lub sijhawm ntev.
Kev ua tau zoo tiag tiag hauv kev txuag hluav taws xob
Los ntawm lub zog-txuag kev xav, tus nqi ntawm airgel pam tsis yog tsuas yog tshwm sim hauv daim ntawv qhia tshwj xeeb. Kev ua haujlwm ruaj khov thermal rwb thaiv tsev txhais tau tias tsis tshua muaj cua sov thaum lub sijhawm ua haujlwm.
Hauv kev tsim kho kev lag luam, qhov no cuam tshuam ncaj qha rau kev siv lub zog ntawm cov cua sov thiab cua txias; nyob rau hauv industrial systems, nws muaj feem xyuam rau lub zog siv efficiency thiab kev khiav hauj lwm nqi. Tshwj xeeb tshaj yog nyob rau hauv siab - kub lossis ib puag ncig nrog qhov kub thiab txias sib txawv, kev ruaj ntseg ntawm thermal rwb thaiv tsev kev ua tau zoo yog qhov tseem ceeb tshaj li "kev ua tau zoo pib," thiab airgel pam vov ua tau zoo rau qhov no.
Cov teeb meem ntawm kev tsim khoom thiab nqi
Ntawm chav kawm, airgel pam tsis yog tsis muaj lawv cov kev cov nyom. Piv rau cov khoom siv rwb thaiv tsev ib txwm muaj, lawv cov txheej txheem tsim khoom yog qhov nyuaj dua, thiab tus nqi kuj tseem siab dua. Qhov no yog vim li cas lawv feem ntau yog qhov tseem ceeb hauv cov haujlwm uas xav tau kev ua haujlwm siab dua lossis qhov chaw lossis qhov hnyav tsawg.
Txawm li cas los xij, nrog kev loj hlob ntawm cov txheej txheem tsim khoom thiab kev lag luam ntawm cov nplai, cov teeb meem rau daim ntawv thov ntawm airgel pam yog maj mam txo qis. Hauv qee qhov haujlwm, txawm hais tias cov khoom siv nws tus kheej kim dua, tus nqi tag nrho tsis nce ntau vim qhov txo qis, siv sijhawm luv dua, thiab qis dua - cov nqi tu lub sijhawm.
Durability thiab kev nyab xeeb
Thaum siv, airgel pam vov muaj qhov kub thiab txias tsis kam, tsis yog -flammable, thiab zoo tshuaj stability, muab lawv tej yam zoo nyob rau hauv industrial thiab pej xeem vaj tse. Piv rau qee cov ntaub ntawv ua npuas ncauj, lawv txoj kev nyab xeeb nyob rau hauv qhov kub thiab txias los yog hluav taws kub tswj tau ntau dua.
Nyob rau lub sijhawm ntev, kev ua haujlwm ruaj khov kuj txhais tau tias tsis tshua muaj kev hloov pauv. Qhov no tau dhau los ua qhov tseem ceeb hauv cov ntsiab lus ntawm kev hais txog lub neej- cov nqi voj voog thiab kev siv peev txheej ua tau zoo.
Ib yam khoom uas yog "In Demand"
Airgel pam tsis tau tsim los hloov tag nrho cov ntaub ntawv rwb thaiv tsev. Lawv tus nqi yog nyob rau hauv kev daws teeb meem qhov twg cov kev daws teeb meem ib txwm tsis tsim nyog: qhov chaw txwv, qhov hnyav, cov qauv nyuaj, thiab kev xav tau siab rau ntev - lub sijhawm ruaj khov.
Nyob rau hauv cov xwm txheej no, "cov rwb thaiv tsev thermal heev thiab ultra-thin thickness" tsis yog cov kev qhia tshwj xeeb xwb, tab sis kev siv tau thiab siv tau zoo engineering. Raws li kev siv hluav taws xob xav tau thiab kev tsim cov kev xav tau nce ntxiv, cov khoom siv no tau raug coj los siv rau hauv ntau txoj haujlwm, maj mam txav los ntawm "kev xaiv tshwj xeeb" mus rau "tus qauv xaiv."
