Kutentha kukana osiyanasiyana ochiritsiranano airgel analiali ndi ntchito yabwino kwambiri yotsekera matenthedwe. Mphamvu yotchinjiriza ya nano airgel imamveka yopambana kwambiri kuposa zida zachikhalidwe zotchinjiriza. Ndiubwino wapadera wamapangidwe a nano porous, yakhala "ace kutchinjiriza kutentha" pansi pamikhalidwe yovuta monga kutentha kwa mafakitale komanso kuzizira kwambiri. Zomwe zimagwirira ntchito zitha kukulitsidwa kuchokera kumagulu otsatirawa: ndi silika aerogel, ndi oposa 90% nano pores mkati, ndipo pore kukula ndi yaying'ono kwambiri kuposa njira yaulere ya mamolekyu mpweya, amene angathe kukulitsa kukana kutentha conduction, convection ndi cheza. 4. Anti thermal shock + kusinthasintha kopepuka, kukhathamira kwambiri kumanga ndi kukonza
nano airgel anamvaNano airgel anamva? Nano airgel adamva ngati "chizindikiro chapamwamba komanso chopulumutsa mphamvu" pakutchinjiriza kwa mafakitale. Zogulitsa za Pa kutentha, kutentha kwake kumakhala kochepa kwambiri ngati 0.018-0.025W / (m · K), yomwe ndi theka la ubweya wa miyala (0.04-0.05W / (m · K)) ndi 60% -70% ya thonje la ceramic fiber (0.03-0.06W / (m · K)). Pansi pa kutentha komweko, makulidwe a airgel amamverera ndi 1/3 - 1/2 ya zida zachikhalidwe, zomwe zimatha kupulumutsa kwambiri malo oyika zida.
nano airgel anamva, zotsatira za nano airgel anamva, matenthedwe kutchinjiriza zotsatira za nano airgel anamva
Kodi matenthedwe amtundu wamafuta amakhudza chiyaniNano airgel anamvachimakwirira -200 ℃ ~ 650 ℃, ndi kusinthidwa mkulu kutentha zosagwira chitsanzo akhoza kufika oposa 1000 ℃. Iwo sangakhoze kokha ntchito ozizira kutchinjiriza wa zipangizo cryogenic monga madzi asafe ndi mpweya mpweya, komanso kukwaniritsa zofunika kutchinjiriza matenthedwe zofunika boilers siteshoni mphamvu, kilns metallurgical, ndi mipope mkulu-kutentha. Chofunika kwambiri, m'madera osiyanasiyana a kutentha kwa kutentha, kutentha kwake kwa kutentha sikusinthasintha kwambiri ndipo kumapangitsa kuti ntchito ikhale yosasunthika, yopambana kwambiri kuposa ubweya wa miyala womwe umakhala wovuta kulephera kwa chinyezi pa kutentha kochepa ndi calcium silicate ndi kuwonjezeka kwadzidzidzi kwa kutentha kwa kutentha pa kutentha kwakukulu.
Kodi kutentha kwa nano airgel kumamveka bwanji?
Mawonekedwe apamwamba a nano airgel adathandizidwa ndi hydrophobicity, ndipo kuchuluka kwa hydrophobicity kumatha kufika kuposa 98%. Ngakhale itakhala nthawi yayitali m'malo onyezimira komanso chinyezi chambiri, sichingatenge chinyezi. Komabe, zida zotchinjiriza zachikhalidwe monga ubweya wamiyala ndi ubweya wagalasi zitha kutsika ndi 50% pakuchita zotsekera pambuyo poyamwa madzi, zomwe zingayambitsenso kuwonongeka kwa zida; Air gel omvera amatha kupewa vutoli, makamaka loyenera kunyowa monga uinjiniya wamankhwala, uinjiniya wam'madzi ndi uinjiniya wapansi panthaka.
5. Osakonda zachilengedwe komanso osagwiritsa ntchito malawi, okhala ndi miyezo yachitetezo yokhudzana ndi chitetezo
Kulemera kwa voliyumu ya airgel kumamveka ndi 180 - 300kg/m ³. Ndizofewa komanso zosinthika, ndipo zimatha kukulungidwa mwachindunji pamwamba pa zinthu zovuta monga mapaipi ooneka ngati apadera, ma valve, ndi zida zopangira flanges. Itha kudulidwa ndikuyika popanda mawonekedwe ovuta, kuwongolera kwambiri kuyika bwino. Panthawi imodzimodziyo, coefficient yake yowonjezera kutentha ndi yotsika kwambiri, yokhoza kupirira kusinthasintha kwa kutentha kwafupipafupi, ndipo sichidzagwedezeka kapena kugwa chifukwa cha kuwonjezereka kwa kutentha ndi kutsika ngati zopangira zolimba. Moyo wake wautumiki ndi nthawi 2-3 kuposa zida zachikhalidwe, kuchepetsa mtengo wokonza pambuyo pake.
3. Hydrophobic ndi chinyezi-proof, sichiwola m'malo achinyezi
Chigawo chachikulu cha nano airgel anamva ndi inorganic silicon dioxide, amene alibe asbestosi, formaldehyde ndi zinthu zina zoipa. Kuchita kwake kuyaka kwafika pamlingo wa Gulu A wosayaka. Sichidzatulutsa mpweya wapoizoni pa kutentha kwakukulu. Imakwaniritsa zofunikira zachitetezo cha chilengedwe cha mafakitale ndi chitetezo chamoto, ndipo ndizoyenera makamaka kwa mankhwala, mphamvu zamagetsi ndi minda yomanga yomwe ili ndi zofunikira zolimba pakuteteza chilengedwe ndi chitetezo.
Malingaliro a kampani Rosewool Insulation Refractory Co., Ltd2. Wide kutentha osiyanasiyana khola anatengera, angathe kugwira ntchito pansi pa mikhalidwe ya pamwamba ndi otsika kutenthaChigawo chapakati chakukhala ndi ultra-low heat conduction of<0.018W/(m ・ K), kukhazikika kosiyanasiyana kwa kutentha kwa -200 ℃~1000 ℃, 99.5%+hydrophobic ndi kusinthasintha kopepuka, ndipo kumatha kupulumutsa mphamvu kwambiri pansi pamikhalidwe yogwira ntchito kwambiri monga kutentha kwakukulu/kuzizira kwambiri //chinyezi. Kuphatikiza zoperekera zakomweko ndi ntchito zaukadaulo zosinthidwa makonda, ndiye chisankho chabwino kwambiri pakukweza kwa mafakitale.
