Puas yog Airgel Waterproof?
Dec 19, 2025
Airgel tau dav lees paub tias yog ib qho ntawm cov khoom siv thermal rwb thaiv tsev zoo tshaj plaws niaj hnub no. Ua tsaug rau nws cov ultra- thermal conductivity tsawg thiab lub teeb yuag, airgel yog siv nyob rau hauv kev lag luam xws li roj & roj thiab petrochemical rau kev tsim kho thiab aerospace. Txawm li cas los xij, ib qho ntawm cov lus nug uas nquag nug los ntawm engineers thiab buyers yog:Puas yog airgel waterproof?
Cov lus teb luv luv yog:Yog lawm, feem ntau cov khoom siv rwb thaiv tsev airgel yog dej -repellent, tab sis daim duab tag nrho nyob ntawm hom airgel thiab daim ntawv thov.Cia wb mus saib ntxiv.
Nkag siab Aerogel's Structure
Airgel yog cov khoom siv nanoporous muaj li ntawm 95-99% huab cua. Nws cov qauv sab hauv muaj qhov sib cuam tshuam qhov pores ntawm nanometer nplai. Thaum cov qauv no yog dab tsi muab airgel nws cov rwb thaiv tsev zoo heev, nws kuj ua rau muaj kev txhawj xeeb txog kev nqus dej noo.
Ntshiab, tsis kho airgel tuaj yeem nqus dej noo. Txawm li cas los xij,industrial airgel rwb thaiv tsev cov khoom yog feem ntau nto -kho los ua hydrophobic.
Puas yog Airgel Hydrophobic?
Yog lawm. Kev lag luam feem ntau muaj airgel rwb thaiv tsev pam thiab felts yoghydrophobic, txhais tau tias lawv tua cov dej es tsis nqus nws.
Hydrophobic aerogel:
Repels kua dej
Tsis wick noo noo
Khaws cov thermal ua haujlwm txawm tias nyob hauv qhov chaw ntub lossis ntub dej
Thaum dej hu rau hydrophobic aerogel, nws hlaws thiab dov tawm es tsis txhob nkag mus rau cov khoom.
Airgel vs Traditional rwb thaiv tsev nyob rau hauv ntub dej
Piv nrog rau cov ntaub ntawv rwb thaiv tsev, airgel ua tau zoo dua hauv cov dej noo- ib puag ncig:
| Cov khoom siv rwb thaiv tsev | Dej tsis kam | Kev ua haujlwm thaum ntub |
|---|---|---|
| iav ntaub plaub | Tsawg | Cov nqi rwb thaiv tsev poob qis heev |
| Mineral ntaub plaub | Nruab nrab | Nws tuaj yeem nqus dej hauv lub sijhawm |
| PU ua npuas ncauj | Nruab nrab-siab | Risk ntawm degradation |
| Airgel rwb thaiv tsev | High (Hydrophobic) |
Kev ua haujlwm tsawg tsawg
|
Qhov no ua rau airgel rwb thaiv tsev tshwj xeeb tshaj yog haum raucov kav dej sab nraum zoov, cov chaw tawm sab nraud, cov chaw LNG, thiab cov chaw ua haujlwm siab -cov av noo.
Puas yog Airgel xav tau kev tiv thaiv dej ntxiv?
Thaum airgel nws tus kheej yog dej -repellent,kev tsim qauv tseem tseem ceeb.
Hauv tiag - ntiaj teb daim ntawv thov:
Airgel rwb thaiv tsev feem ntau ua ke nrogtiv thaiv tsho los yog cladding(aluminium, stainless hlau, lossis polymer tsho).
Cov pob qij txha kaw thiab kev txhim kho kom zoo pab tiv thaiv kom ntev - lub sij hawm ya raws ingress.
Rau submerged los yog tas li raug tej yam kev mob, ntxiv waterproof txheej raug pom zoo.
Airgel tsis hloov cov ntaub thaiv dej, tab sis nwstxo cov dej noo ntau heev- cuam tshuam txog rwb thaiv tsev tsis ua haujlwm.
Yuav ua li cas dej raug cuam tshuam rau Airgel Performance
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm aerogel yog qhov ntawdnws cov thermal conductivity tseem ruaj khov txawm tias tom qab dej raug. Tsis zoo li fibrous rwb thaiv tsev, airgel tsis tawg los yog poob qauv thaum ntub.
Cov txiaj ntsig muaj xws li:
Kev ua tau zoo ntawm rwb thaiv tsev
Txo corrosion nyob rau hauv rwb thaiv tsev (CUI) kev pheej hmoo
Kev ziab sai dua piv rau cov khoom siv niaj hnub
Qhov no yog vim li cas airgel feem ntau xaiv rauCov cuab yeej tseem ceeb uas tswj cov dej noo yog qhov tseem ceeb.
Daim ntawv thov qhov twg Waterproof Airgel tseem ceeb tshaj plaws
Hydrophobic airgel rwb thaiv tsev feem ntau siv hauv:
Roj & roj pipelines
Tshuaj ua cov nroj tsuag
Cov chaw tsim hluav taws xob
Marine thiab offshore ib puag ncig
Cryogenic thiab LNG systems
Hauv cov xwm txheej no, kev tiv thaiv dej noo yog ib qho tseem ceeb xws li thermal efficiency.
Lus Nug: Puas yog Airgel Waterproof?
Yog - cov ntaub ntawv rwb thaiv tsev airgel niaj hnub no yog dej-repellent thiab tiv taus noo noo.Thaum airgel nws tus kheej tsis yog ib qho thaiv dej, nws cov khoom siv hydrophobic ua kom muaj kev ua tau zoo hauv qhov chaw ntub dej thiab ntub dej thaum nruab.
Rau cov kev lag luam uas rwb thaiv tsev tsis ua hauj lwm vim dej noo yog ib qho kev txhawj xeeb loj, airgel muaj kev ntseeg siab, ntev ntev - daws teeb meem uas ua tau zoo dua cov khoom siv rwb thaiv tsev.
