Kev Qhia Txog Kev Yuav: Yuav Ua Li Cas Xaiv High-Quality Airgel

Kev Qhia Txog Kev Yuav: Yuav Ua Li Cas Xaiv High-Quality Airgel

Airgel feem ntau tau piav qhia tias yog "cov khoom siv rwb thaiv tsev super" vim nws cov thermal conductivity tsawg, lub teeb yuag, thiab kev ua tau zoo heev hauv qhov xav tau ib puag ncig. Ameslikas tsim rau aerospace daim ntaub ntawv, airgel yog tam sim no dav siv nyob rau hauv industrial rwb thaiv tsev, kev tsim kho, roj thiab roj, thiab lub zog- txuag tej yaam num. Txawm li cas los xij, tsis yog txhua yam khoom siv airgel muaj qhov zoo ib yam. Kev nkag siab txog kev ntsuas airgel kom raug yog qhov tseem ceeb ua ntej kev yuav khoom.

1. Nkag siab hom Airgel

Kev lag luam airgel feem ntau yog raws li silica, txawm hais tias polymer-raws li thiab carbon aerogels kuj muaj. Silica airgel yog qhov kev xaiv ntau tshaj plaws rau cov rwb thaiv tsev thermal vim nws ua ke nrog cov thermal conductivity tsawg nrog tshuaj stability thiab hluav taws kub. Thaum xaiv aerogel, paub meej tias cov khoom siv hauv paus thiab xyuas kom meej tias nws phim koj daim ntawv thov, xws li qhov kub thiab txias, lub zog ntawm lub zog, thiab ib puag ncig raug.

2. Txheeb xyuas qhov ua tau zoo ntawm cov thermal conductivity

Ib qho ntawm cov laj thawj tseem ceeb ntawm kev xaiv airgel yog nws txoj kev muaj peev xwm zoo tshaj plaws. High-zoo airgel feem ntau muaj cov thermal conductivity ntawm 0.012 thiab 0.020 W/m·K ntawm chav tsev kub, qis dua li cov khoom siv rwb thaiv tsev ib txwm muaj. Cov neeg tsim khoom yuav tsum muab cov ntaub ntawv soj ntsuam raws li cov qauv lees paub, xws li ASTM lossis ISO txoj kev. Ceev faj ntawm cov khoom lag luam uas thov cov nqi qis heev yam tsis muaj ntawv pov thawj kev xeem.

3. Txheeb xyuas qhov ntom ntom thiab cov qauv

Airgel paub txog nws cov qauv nanoporous, uas yog lub luag haujlwm rau nws qhov kev ua tau zoo. Qhov ntom ntom qis feem ntau qhia tau tias muaj kev rwb thaiv tsev zoo dua, tab sis qhov ntom ntom tsis tshua muaj peev xwm txo cov neeg kho tshuab lub zog. Rau cov kev siv tswv yim, airgel feem ntau muab rau hauv cov ntaub ntawv txhawb zog, xws li cov pam vov lossis cov vaj huam sib luag, qhov twg airgel hais nrog cov fibers. A good balance between low density and structural integrity is crucial for long-term reliability.

4. Ntsuas Mechanical Strength thiab Flexibility

Pure airgel yog qhov tsis yooj yim, yog li cov khoom lag luam feem ntau yog tsim los txhim kho cov kav ntev. Piv txwv li, airgel pam yuav tsum hloov tau, tsim kua muag -resistant, thiab yooj yim rau txiav thiab nruab. Panels yuav tsum tswj cov duab nyob rau hauv load yam tsis muaj cracking. Kev tshuaj xyuas lub zog compression thiab tensile lub zog cov ntaub ntawv tuaj yeem pab txiav txim siab seb cov khoom puas tuaj yeem tiv taus kev teeb tsa thiab kev ua haujlwm nyuaj.

5. Xav txog cov dej noo thiab Hydrophobic Properties

High -zoo airgel rwb thaiv tsev yog feem ntau hydrophobic, txhais tau tias nws repels dej. Cov cuab yeej no yog qhov tseem ceeb rau kev tswj xyuas kev ua haujlwm rwb thaiv tsev hauv qhov chaw ntub lossis sab nraum zoov. Xyuas seb lub airgel puas tau nto- kho kom tiv thaiv kev nqus dej, thiab xyuas kom meej tias nws qhov kev ua haujlwm thermal tseem nyob ruaj khov tom qab raug dej lossis av noo.

6. Saib xyuas qhov ntsuas hluav taws thiab kev nyab xeeb

Kev nyab xeeb yog qhov tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv kev tsim kho thiab kev lag luam. Silica airgel feem ntau tsis yog-combustible, tab sis cov khoom sib xyaw yuav suav nrog cov ntawv khi lossis fibers uas cuam tshuam rau kev ua haujlwm hluav taws. Saib rau qhov ntsuas hluav taws kub, xws li ASTM E84 lossis EN 13501, txhawm rau ua raws li cov cai hauv zos.

7. Txheeb xyuas qhov chaw tsim khoom muaj kev ntseeg siab thiab ntawv pov thawj

Thaum kawg, xaiv cov khoom siv airgel los ntawm cov tuam txhab muaj koob npe nrog kev paub dhau los. Cov neeg muag khoom ntseeg tau muab cov khoom zoo sib xws, cov ntaub ntawv qhia ntxaws ntxaws, thiab cov ntawv pov thawj thib peb ntawm - tog. Ntev- cov ntaub ntawv kev ua tau zoo thiab cov ntaub ntawv xa mus los ntawm cov haujlwm tiag tiag yog cov cim qhia txog kev ntseeg tau ntawm cov khoom.

Xaiv lub siab - zoo airgel yuav tsum tau ntau tshaj qhov sib piv cov nqi. Los ntawm kev nkag siab txog cov khoom siv, kev ua haujlwm thermal, cov khoom siv kho tshuab, cov dej tsis zoo, thiab cov qauv kev nyab xeeb, cov neeg yuav khoom tuaj yeem txiav txim siab paub. Ib qho khoom zoo - xaiv airgel tsis tsuas yog xa cov rwb thaiv tsev zoo xwb tab sis kuj ua kom muaj kev ruaj ntseg, kev nyab xeeb, thiab ntev - lub sij hawm tus nqi nyob rau hauv tiag - ntiaj teb daim ntawv thov.
