Silica Airgel Insulation Board

Nqe lus piav qhia:

Silica airgel rwb thaiv tsev pawg thawj coj saib yog cov khoom tawg yooj yim uas muaj cov khoom sib xyaw ua ke sib xyaw ua ke rau hauv cov qauv nanoporous network, thiab qhov sib txawv tau ntim nrog cov roj cua nruab nrab. Nws qhov porosity tuaj yeem ncav cuag 80 ~ 99.8%, qhov pore loj yog feem ntau ntawm 1 ~ 70nm, thiab nws qhov ntom yog lub teeb zoo li tsuas yog 2.75 npaug ntawm huab cua ntom ntom, uas tsis sib xws los ntawm lwm cov khoom siv rwb thaiv tsev hauv thaj chaw rwb thaiv tsev hauv ntiaj teb niaj hnub no .

Silica airgel rwb thaiv tsev pawg thawj coj saib muaj cov khoom zoo xws li tsis muaj cua sov ua kom sov, tiv taus kub, tiv thaiv hluav taws, tsis ntom ntom, thiab tsis muaj suab nrov cuam tshuam. Nyob rau tib lub sijhawm, nws tseem muaj dej tsis kam thiab ua haujlwm ntev. Hauv kev tsav dav hlau, kev tiv thaiv lub teb chaws, kev sib txuas lus, kev kho mob, roj av, tshuaj lom neeg, cov tsheb thauj mus los, nkoj, lub zog tshiab, hluav taws xob nuclear, kev tsim kho, kev tiv thaiv ib puag ncig, thiab tsheb, muaj kev thov dav heev.

Lub cev muaj zog:

Ntim daim ntawv: yob

Thickness: 5mm, 8mm, 10mm

Dav: 1500 hli

Ceev: 180-220kg/m3

Qhov ntsuas kub uas siv tau: -200 ℃ ——1000 ℃ (cuam tshuam nrog tus qauv)

Hydrophobicity: Hydrophobic kiag li (qis dua 350 ° C)

Kev ua kom sov: 0.012-0.018w/m · k (ntawm 25 ℃)

Qhov Zoo:

1. Kev pab lub neej

Raws li kev sim Arrhenius, kev xav theoretical lub neej yog 20 xyoo, uas yuav luag zoo ib yam li lub neej ntawm lub tsev.

2. Txo qhov tuab ntawm txheej rwb thaiv tsev

Silica airgel rwb thaiv tsev pawg thawj coj ua tau zoo ib yam cov cua sov ua kom sov, thiab nws cov tuab tsuas yog ib feem ntawm cov khoom siv ib txwm muaj. Tom qab kev txuag hluav taws xob, qhov cua sov poob me me thiab qhov chaw siv qhov chaw siab. Thiab ntawm qhov kub siab, qhov ua tau zoo saum toj no yog qhov pom tseeb dua.

3. Hydrophobicity thiab tiv taus hluav taws

Silica airgel rwb thaiv tsev pawg thawj coj saib yog tsis muaj dej-pov thawj, uas tuaj yeem tiv thaiv tau cov dej nkag los ntawm cov raj xa dej thiab cov khoom siv. Nyob rau tib lub sijhawm, nws tau tsim kev tiv thaiv hluav taws kev ua haujlwm, thiab qhov tshwj xeeb peb-txheej txheej qauv ntawm airgel zam qhov txo qis ntawm kev txuag hluav taws xob xws li sintering deformation thiab sedimentation ntawm lwm cov khoom khaws cia cua sov thaum lub sij hawm siv kub ntev.

4. Kev tsim kho yooj yim

Silica airgel rwb thaiv tsev pawg thawj coj saib yog lub teeb yuag, yooj yim txiav thiab xaws kom hloov mus rau ntau yam duab ntawm cov kav dej thiab cov cuab yeej siv rau kev txuag hluav taws xob, thiab nws xav tau sijhawm tsawg dua thiab siv zog rau kev teeb tsa.

5. Txuag tus nqi thauj mus los

Ntim pob me me thiab hnyav dua tuaj yeem txo qis kev thauj mus los ntawm cov khoom siv rwb thaiv tsev.
