Txheej Aerogel
Qhov kev ua tau zoo tshaj plaws ntawm cov txheej txheej airgel yog los ntawm cov qauv me me ntawm nws cov khoom tseem ceeb - nano-aerogel. Cov qauv no ua rau nws thaiv tau peb txoj kev xa cua sov: cov khoom siv xa cua sov, cov cua sov xa cua sov, thiab cov hluav taws xob thermal.
Kev rwb thaiv cua sov zoo tshaj plaws thiab txuag hluav taws xob zoo: Qhov no yog qhov ua tau zoo ntawm cov txheej txheej airgel. Lawv cov thermal conductivity qis heev, feem ntau yog li ntawm 0.030 W / (m · K) lossis li ntawd, uas qis dua li cov ntaub ntawv rwb thaiv tsev ib txwm muaj. Qhov no txhais tau tias ib txheej nyias heev (xws li 2-3 hli) tuaj yeem ua tiav cov nyhuv rwb thaiv tsev sib npaug rau cov ntaub ntawv rwb thaiv tsev ib txwm muaj (xws li 30-40 hli), txo qis kev poob hluav taws xob thiab ua tiav kev txuag hluav taws xob thiab kev siv hluav taws xob tsawg dua.
Kev tiv thaiv hluav taws zoo heev thiab kev tiv thaiv hluav taws kub: Cov txheej txheej Airgel feem ntau muaj cov qib tiv thaiv hluav taws zoo. Ntau yam khoom tuaj yeem ncav cuag cov qauv hauv tebchaws ntawm A-level tsis kub hnyiab lossis A2-level hluav taws kub tiv thaiv, uas tuaj yeem ncua qhov kev sib kis ntawm hluav taws thiab txhim kho kev nyab xeeb ntawm cov khoom coated.
Lub teeb yuag thiab muaj zog nplaum: Airgel nws tus kheej yog ib qho ntawm "cov khoom sib dua tshaj plaws" hauv ntiaj teb. Yog li ntawd, cov txheej tsim tom qab ziab ntawm cov xim muaj qhov ceev tsawg thiab lub teeb yuag, thiab yuav tsis ua rau lub nra hnyav ntau dhau rau ntawm lub substrate. Tib lub sijhawm, los ntawm kev ua kom zoo dua ntawm cov mis, lub zog nplaum ntawm cov txheej thiab lub substrate xws li hlau thiab pob zeb yog siab, thiab nws tsis yooj yim poob lossis tawg.
Kev tiv thaiv dej, tiv thaiv dej thiab tiv thaiv xeb: Lub aerogel nws tus kheej yog hydrophobic, uas ua rau lub txheej txheej muaj cov yam ntxwv zoo heev tiv thaiv dej thiab tiv thaiv dej noo. Nws tuaj yeem tiv thaiv cov pa dej kom tsis txhob lwj lub substrate thiab tiv thaiv kev sib sau ua ke ntawm qhov chaw ntawm cov khoom siv hauv kev lag luam. Qee cov txheej txheej kuj muaj cov haujlwm tiv thaiv xeb, uas tuaj yeem ua rau lub neej ua haujlwm ntawm cov khoom siv ntev dua.
Ntsuab thiab zoo rau ib puag ncig, yooj yim siv: Cov txheej txheem airgel feem ntau muaj tam sim no feem ntau yog cov txheej txheem dej, tsis muaj lossis tsuas yog me me ntawm cov organic sib xyaw ua ke, tsis muaj tshuaj lom thiab tsis ua rau ib puag ncig puas tsuaj. Lawv tsim nyog rau ntau txoj kev siv xws li txhuam, txheej txheej roller, thiab txau, thiab yooj yim tshwj xeeb rau kev tsim cov txheej rwb thaiv tsev tsis muaj qhov tsis sib xws ntawm cov nplaim ntawm cov haujlwm tsis sib xws xws li cov li qub thiab flanges.
Lwm yam khoom: Dhau li ntawm cov yam ntxwv saum toj no, cov txheej txheem airgel feem ntau muaj qhov zoo xws li kev rwb thaiv suab thiab txo suab nrov, kev tiv thaiv kev laus, lub neej ntev, thiab kev ruaj khov thermal zoo ntawm qhov kub siab.
Kev rwb thaiv tsev rau cov kav dej kub, cov thoob dej cia khoom, cov hlab dej tshuaj tiv thaiv, cov cub tawg thiab lwm yam khoom siv hauv kev lag luam xws li petrochemicals, fais fab, thiab metallurgy;
Kev rwb thaiv tsev thiab cua sov rau sab hauv thiab sab nraud phab ntsa, ru tsev, thiab pem teb ntawm cov tsev, nrog rau cov phab ntsa ntaub thaiv thiab cov chaw tsim khoom hlau;
Kev rwb thaiv cua sov thiab kev tiv thaiv hluav taws rau cov roj teeb ntawm cov tsheb fais fab tshiab, tiv thaiv kev kis tus kab mob thermal ntawm roj teeb; Kev rwb thaiv cua sov thiab kev tiv thaiv hluav taws rau cov kab ke thauj mus los, nkoj, tsheb tub yees, thiab lwm yam.
Siv rau kev rwb thaiv tsev cua sov hauv cov khaub ncaws chaw thiab cov dav hlau hauv thaj chaw aerospace; Cov txheej txheem tiv thaiv hluav taws rau cov cables; thiab cov khoom lag luam sab nraum zoov uas ua tau zoo (xws li khaub ncaws tiv thaiv txias, hnab pw, khob npog rwb thaiv tsev, thiab lwm yam)
