Qhov kub tsis kam ntau yam ntawm cov panano airgel sivmuaj kev ua haujlwm zoo thermal rwb thaiv tsev. Cov nyhuv thermal rwb thaiv tsev ntawm nano airgel xav tau zoo dua li ntawm cov khoom siv thermal rwb thaiv tsev. Nrog rau qhov tshwj xeeb zoo ntawm nano ntxeem tau qauv, nws tau dhau los ua "cov rwb thaiv tsev kub" nyob rau hauv cov xwm txheej hnyav xws li kev lag luam kub thiab txias txias. Cov kev ua haujlwm tshwj xeeb tuaj yeem nthuav dav los ntawm cov ntsiab lus hauv qab no:
yog silica aerogel, nrog ntau tshaj 90% nano pores sab hauv, thiab qhov pore loj yog deb me dua li txoj kev dawb ntawm huab cua molecules, uas tuaj yeem ua kom muaj kev tiv thaiv tshav kub, convection thiab hluav taws xob.

4. Kev tiv thaiv thermal shock + lub teeb yuag yooj yim, kev txhawj xeeb ntau dua kev tsim kho thiab kev saib xyuas

nano airgel xavNano airgel xav tau? Nano airgel xav tau yog "kev ua haujlwm siab thiab txuag hluav taws xob" rau kev lag luam rwb thaiv tsev. Cov khoom ntawm
Nyob rau hauv chav tsev kub, nws thermal conductivity tsawg li 0.018-0.025W/(m · K), uas tsuas yog ib nrab ntawm pob zeb ntaub plaub (0.04-0.05W/(m · K)) thiab 60% -70% ntawm ceramic fiber paj rwb (0.03-0.06W/(m · K)). Nyob rau hauv tib lub thermal rwb thaiv tsev nyhuv, lub thickness ntawm airgel xav tsuas yog 1 / 3 - 1 / / 2 ntawm cov khoom siv ib txwm, uas tuaj yeem txuag tau ntau qhov chaw teeb tsa.

nano airgel xav, cuam tshuam ntawm nano airgel xav, thermal rwb thaiv tsev nyhuv ntawm nano airgel hnov

Dab tsi yog qhov thermal rwb thaiv tsev nyhuv ntawmNano airgel xav taunpog -200 ℃ ~ 650 ℃, thiab hloov kho kub resistant qauv tuaj yeem ncav cuag ntau tshaj 1000 ℃. Nws tuaj yeem tsis tsuas yog siv rau kev rwb thaiv tsev txias ntawm cov khoom siv cryogenic xws li kua nitrogen thiab kua oxygen, tab sis kuj ua tau raws li cov txheej txheem thermal rwb thaiv tsev ntawm lub hwj chim chaw nres tsheb boilers, metallurgical kilns, thiab cov kav dej kub.
Qhov tseem ceeb tshaj, nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias ib puag ncig, nws cov thermal conductivity tsis hloov pauv loj thiab tswj kev ua haujlwm ruaj khov, zoo dua rau pob zeb ntaub plaub uas ua rau tsis muaj dej tsis zoo ntawm qhov kub thiab txias thiab calcium silicate nrog kev nce siab ntawm thermal conductivity ntawm qhov kub thiab txias.

Dab tsi yog qhov thermal rwb thaiv tsev nyhuv ntawm nano airgel xav?

Qhov zoo tshaj plaws nano airgel xav tau raug kho nrog hydrophobicity, thiab tus nqi hydrophobicity tuaj yeem ncav cuag ntau dua 98%. Txawm hais tias nws nyob hauv qhov chaw ntub dej thiab cov av noo siab ntev, nws yuav tsis nqus dej noo.
Txawm li cas los xij, cov ntaub ntawv rwb thaiv tsev ib txwm muaj xws li pob zeb wool thiab iav ntaub plaub yuav ua rau txo qis dua 50% hauv kev ua haujlwm rwb thaiv tsev tom qab nqus dej, uas tuaj yeem ua rau cov khoom siv corrosion; Cua gel xav tau tuaj yeem zam qhov teeb meem no, tshwj xeeb tshaj yog tsim rau cov dej ntub dej xws li tshuaj lom neeg engineering, marine engineering thiab underground engineering.

5. Ib puag ncig tus phooj ywg thiab nplaim-retardant, nrog kev nyab xeeb kev ua tau zoo raws li cov qauv

Qhov hnyav ntawm lub airgel xav tsuas yog 180 - 300kg / m ³. Nws yog mos thiab yoog raws, thiab tuaj yeem muab qhwv ncaj qha rau ntawm qhov chaw ntawm cov txheej txheem nyuaj xws li cov kav dej tshwj xeeb, li qub, thiab cov khoom siv flanges. Nws tuaj yeem raug txiav thiab pasted yam tsis muaj kev ua haujlwm nyuaj, txhim kho kev ua haujlwm zoo heev.
Nyob rau tib lub sijhawm, nws cov coefficient ntawm thermal expansion yog tsawg heev, muaj peev xwm tiv taus qhov kub thiab txias hloov pauv, thiab yuav tsis tawg lossis poob vim thermal expansion thiab contraction zoo li nyuaj castables. Nws lub neej kev pabcuam yog 2-3 zaug ntev dua li cov khoom siv ib txwm siv, txo cov nqi kho mob tom qab.

3. Hydrophobic thiab noo noo-pov thawj, tsis lwj hauv qhov chaw ntub dej

Lub ntsiab tivthaiv ntawm nano airgel xav yog inorganic silicon dioxide, uas tsis muaj asbestos, formaldehyde thiab lwm yam teeb meem. Nws qhov kev ua haujlwm combustion tau mus txog Class A uas tsis yog combustible standard. Nws yuav tsis tso cov pa phem rau ntawm qhov kub thiab txias. Nws ua tau raws li qhov yuav tsum tau muaj kev tiv thaiv ib puag ncig thiab kev nyab xeeb hluav taws, thiab tshwj xeeb tshaj yog tsim rau cov tshuaj lom neeg, hluav taws xob hluav taws xob thiab kev tsim kho thaj chaw uas muaj cov cai nruj rau kev tiv thaiv ib puag ncig thiab kev nyab xeeb.

Rosewool rwb thaiv tsev Refractory Co., Ltd 2. Dav kub ntau ruaj khov adaptation, muaj peev xwm ua hauj lwm nyob rau hauv ob qho tib si kub thiab tsis kub tej yam kev mobCov ntsiab lus tseem ceeb ntawmmuaj ultra-low tshav kub conduction ntawm <0.018W/(m ・ K), dav kub ntau yam stability ntawm -200 ℃ ~ 1000 ℃, 99.5% + hydrophobic thiab lub teeb yuag yooj, thiab yuav txuag tau lub zog ho nyob rau hauv loj heev ua hauj lwm tej yam kev mob xws li kub kub / tob txias / humidity. Muab cov khoom xa tuaj hauv zos thiab cov kev pabcuam tshwjxeeb, nws yog qhov kev xaiv zoo tshaj plaws rau kev txhim kho rwb thaiv tsev.
