Nyob rau hauv lub aerospace teb
Airgel thermal rwb thaiv tsev cov ntaub ntawv tuaj yeem siv los ua cov khoom siv thermal rwb thaiv tsev ntawm lub dav hlau hauv tsev, uas tuaj yeem txhim kho cov thermal rwb thaiv tsev, txo cov cua sov hauv tsev, txo cov khoom siv thermal rwb thaiv tsev, ua kom qhov chaw siv hauv tsev, thiab txhim kho ntau yam. chaw ua haujlwm.Airgel thermal rwb thaiv tsev cov ntaub ntawv tuaj yeem ua tiav cov txiaj ntsig zoo thermal rwb thaiv tsev nrog cov khoom sib zog thiab cov ntim me me, uas muaj txiaj ntsig zoo hauv kev siv aviation thiab aerospace.
Hauv kev tsim kho
Nrog rau kev txhim kho txuas ntxiv ntawm lub teb chaws cov kev cai rau kev txuag hluav taws xob thiab txo qis emissions, thiab tib neeg txoj kev nrhiav kev ua neej zoo, lub tsev rwb thaiv tsev tau maj mam dhau los ua lub ntsiab lus tseem ceeb hauv kev tsim kho.Rau ib lub tsev, yuav luag txhua qhov chaw, muaj kev koom tes hauv kev xav tau thermal rwb thaiv tsev, tshwj xeeb tshaj yog nyob rau hauv lub tsev phab ntsa rwb thaiv tsev, rwb thaiv tsev ru tsev.Silica airgel tuaj yeem tiv taus qhov kub thiab txias, feem ntau ntawm 800 ℃, nws cov qauv, kev ua tau zoo tsis muaj qhov hloov pauv, muaj kev nyab xeeb, txuag hluav taws xob, kev tiv thaiv ib puag ncig ntawm cov khoom siv rwb thaiv tsev super.
Hauv kev thauj mus los
Lub tshav kub rwb thaiv tsev kev ua tau zoo ntawm lub tsheb lub ru tsev yog ib qho ntawm cov tseem ceeb uas cuam tshuam rau lub tshav kub hloov ntawm lub tsheb lub cev.Nws yog ib qho tseem ceeb heev rau kev txheeb xyuas qhov kev siv lub zog ntawm kev ua haujlwm ntawm lub tsheb, txiav txim siab nws cov huab cua txias, tsis txhob muaj qhov tshwm sim ntawm kev ua haujlwm tsis zoo, thiab tswj xyuas qhov chaw sov so hauv lub tsheb.Nyob rau hauv lub tshav pob ntawm lub zog tshiab, hluav taws xob tsheb hluav taws xob thiab hluav taws xob tawg tshwm sim los ntawm lithium ion roj teeb "thermal runaway" tau tshaj tawm ntau zaus.Yuav ua li cas kom ntseeg tau tias cov cua sov dissipation thiab kev nyab xeeb ntawm lithium roj teeb tau dhau los ua "nqaij ntawm Damocles" dai ntawm lub taub hau ntawm cov tuam txhab tsheb thiab cov tuam txhab roj teeb hluav taws xob.Nanoporous airgel composite rwb thaiv tsev cov ntaub ntawv tau siv rau high-speed tsheb ciav hlau, domestic C919 neeg nrog caij dav hlau, thiab lub zog tshiab tsheb, tshwj xeeb tshaj yog tsom rau lub tshav kub rwb thaiv tsev ntawm tsheb thauj mus los thiab kev tiv thaiv ntawm lithium roj teeb nyob rau hauv lub zog tshiab tsheb.
Specification
Raws li kev xaiv ntawm cov substrate sib txawv, airgel lev tuaj yeem xaiv cov khoom sib txawv raws li cov neeg siv khoom sib txawv thiab cov xwm txheej.Tam sim no, muaj plaub lub iav fiber ntau sib xyaw aerogels (HHA-GZ), preoxygenated hlau fiber ntau sib xyaw aerogels (HHA-YYZ), siab silicon oxygen fiber ntau aerogels (HHA-HGZ) thiab ceramic fiber ntau aerogels (HHA-TCZ). ).Specification parameter yog raws li nram no:
Raws li cov txheej txheem kev tiv thaiv hluav taws xob, cov ntaub thaiv hluav taws xob rwb thaiv tsev tuaj yeem muab faib ua peb hom: hom thaiv, hom kev xav thiab hom hluav taws xob.peb lub tuam txhab suzhou supxtech tuaj yeem muab cov Airgel txheej tshuab thiab cov tshuab, nws tuaj yeem siv rau colth, yas ntawv thiab muaj kev xav.nws widly siv rau qhov chaw sov so.
Barrier tshav kub rwb thaiv tsev txheej yog ib hom passive txias txheej uas paub txog cov rwb thaiv tsev kub los ntawm impedance cuam tshuam ntawm cov cua sov hloov.Lub tshuab hluav taws xob rwb thaiv tsev yog qhov yooj yim, thiab cov khoom sib xyaw nrog cov thermal conductivity tsawg lossis cov huab cua uas tsis tshua muaj thermal conductivity yog nkag mus rau hauv cov yeeb yaj kiab kom tau txais cov hluav taws kub zoo.Nws feem ntau muaj cov yam ntxwv ntawm qhov loj me me, tsis tshua muaj thermal conductivity thiab me me dielectric tas li.
Reflective tshav kub rwb thaiv tsev txheej yog cais lub hnub ci zog nyob rau hauv daim ntawv ntawm kev xav.Feem ntau siv cov ntaub ntawv muaj xws li ceramic hmoov, txhuas hmoov, titanium dioxide thiab ATO (antimony doped tin dioxide) hmoov.
Cov txheej txheem txheej txheej txheej txheej txheej tus neeg saib xyuas raws li cov qauv tshuaj, feem ntau suav nrog polyvinyl chloride (PVC), polyacrylate (PA), polyurethane (PU), silicone, roj hmab emulsion thiab polytetrafluoroethylene, uas PA thiab PU yog siv ntau dua;Raws li kev siv nruab nrab, tuaj yeem muab faib ua hnyav thiab dej dispersed hom 2.
SiO2 airgel yog cov khoom siv amorphous nanoporous nrog cov qauv tswj tau thiab txuas ntxiv peb-dimensional network qauv.Thiab nws qhov ceev yog kho tau ntawm 3 ~ 500mg / cm3, yog lub ntiaj teb qhov qis tshaj plaws ntawm cov khoom siv, porosity tuaj yeem ncav cuag 80% ~ 99.8%, qhov pore loj ntawm 1 ~ 100nm, thaj chaw tshwj xeeb tuaj yeem ncav cuag 1000m2 / g.Vim nws cov qauv nanoporous tshwj xeeb, nws cov thermal conductivity tsis tshua muaj qis, qis li 0.017W / (m•K) ntawm chav tsev kub thiab siab, ua rau nws cov khoom siv qis tshaj plaws nrog thermal conductivity.Vim hais tias cov qauv ntawm cov pob txha pob txha ntawm airgel yog me dua lub wavelength ntawm pom lub teeb, nws kuj muaj lub teeb kis tau tus mob zoo.Nyob rau tib lub sijhawm, nws yog cov khoom siv inorganic, uas tsis yog-combustible los yog nplaim retardant nyhuv, nyob rau hauv lub tshav kub rwb thaiv tsev muaj ib tug ntau yam ntawm daim ntawv thov prospects.
