Airgel Thermal insulator txheej khoom

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.
