Kev Taw Qhia Txog Khoom
Airgel yog ib hom khoom khov kho uas muaj kev ua tau zoo heev ntawm kev rwb thaiv tsev thermal, nrog rau thaj chaw tshwj xeeb siab, nano-level pores, qis density thiab lwm yam microstructure tshwj xeeb, nws hu ua "cov khoom siv khawv koob uas hloov lub ntiaj teb", tseem hu ua "cov khoom siv rwb thaiv tsev thermal kawg", yog cov khoom khov kho sib dua. Airgel muaj peb-seem nano-network porous qauv, nrog rau qhov ceev qis, thaj chaw tshwj xeeb siab, porosity siab, dielectric tsis tu ncua qis, thermal conductivity qis thiab lwm yam khoom siv lub cev, thiab muaj ntau yam kev cia siab rau hauv cov teb ntawm thermal rwb thaiv tsev, hluav taws kub retardant, suab rwb thaiv tsev, txo suab nrov, optics, hluav taws xob thiab lwm yam.
Cov yam ntxwv ntawm kev ua tau zoo
1, Kev rwb thaiv tshav kub thiab kev kub siab
Cov khoom siv thermal conductivity qis, cov khoom siv thermal conductivity ntawm cov khoom ib txwm muaj yog 0.018 ~ 0.020 W / (mK), qis li 0.014 W / (mK), txhua qhov kub thiab txias qis dua cov khoom sib piv, qhov siab tshaj plaws tuaj yeem tiv taus 1100 ℃ kub siab, cov nyhuv rwb thaiv tsev thermal zoo dua li cov khoom ib txwm muaj 3-5 zaug, ua haujlwm tau zoo thiab txuag hluav taws xob.
2, Dej tsis nkag thiab ua pa tau
Nrog rau kev ua tau zoo heev ntawm kev tiv thaiv dej, tus nqi tiv thaiv dej ≥99%, cais cov dej ua kua, thaum tso cai rau cov pa dej hla dhau.
3, Hluav taws kub thiab tsis kub hnyiab
Hauv cov qauv qib combustion hauv tsev kom ua tiav qib siab tshaj plaws ntawm A1, hauv cov khoom siv sab hauv tsheb qib combustion kuj tau mus txog qib siab tshaj plaws ntawm A uas tsis kub hnyiab.
4, Kev nyab xeeb thiab kev tiv thaiv ib puag ncig
Cov khoom lag luam tau dhau qhov kev xeem RoHS thiab REACH, thiab tsis muaj cov tshuaj lom neeg rau tib neeg lub cev, thiab cov ntsiab lus ntawm cov chloride ions soluble yog me me heev.
5, Tensile thiab compression tsis kam, yooj yim siv thiab thauj mus los
Zoo yooj ywm thiab tensile / compressive zog, tsis muaj kev sib haum xeeb thiab deformation hauv kev siv mus sij hawm ntev; lub teeb thiab yooj yim, yooj yim txiav, kev tsim kho zoo, haum rau ntau yam kev xav tau ntawm cov duab, cov nqi thauj mus los tsawg.
Qauv Qhia Txog
Raws li kev xaiv cov khoom siv sib txawv, cov ntaub pua plag airgel tuaj yeem xaiv cov koob sib txawv raws li cov kev xav tau thiab cov xwm txheej ntawm cov neeg siv khoom. Tam sim no, muaj plaub koob ntawm cov iav fiber composite airgel (HHA-GZ), pre-oxygenated fiber composite airgel (HHA-YYZ), high silica oxygen fiber composite airgel (HHA-HGZ) thiab ceramic fiber composite airgel (HHA-TCZ).
Cov txheej txheem parameter yog raws li nram no:
