Mitundu isanu ndi umodzi yama nanomaterials yamafuta omwe amagwiritsidwa ntchito kwambiri

1. Nano diomand

Diamondi ndizomwe zimakhala ndi matenthedwe otentha kwambiri m'chilengedwe, ndimayendedwe ofikira mpaka 2000 W / (mK) kutentha, kutentha kozungulira kozungulira kwa pafupifupi (0.86 ± 0.1) * 10-5 / K, ndikutchinjiriza kuchipinda kutentha, Kuphatikiza apo, diamondi imakhalanso ndi makina abwino kwambiri, owonera, owonera, magetsi ndi mankhwala, zomwe zimapangitsa kuti zikhale ndi mwayi wowonekera pakatenthedwe kazipangizo zamagetsi zamagetsi, zomwe zikuwonetsanso kuti diamondi imatha kugwiritsa ntchito gawo lotha kutentha.
2. BN

Mapangidwe a kristalo a hexahedral boron nitride ndi ofanana ndi a graphite dongosolo. Ndi ufa wonyezimira wodziwika ndi kutakasuka, mafuta, kuyamwa kosavuta komanso kulemera kocheperako.Kulingalira kwamphamvu ndi 2.29g / cm3, kuuma kwa mohs ndi 2, ndipo mankhwala ndi osasunthika kwambiri. argon pamatentha mpaka 2800 It. Sikuti imangokhala ndi kutentha kozama kozizira, komanso imakhala ndi matenthedwe otentha kwambiri, sikuti ndiwotchinjitsa wabwino wokha, koma wotetezera wamagetsi wamba. pa 300K.

3. SIC

Katundu wa silicon carbide ndi wosasunthika, ndipo matenthedwe ake matenthedwe amaposa omwe amadzaza ma semiconductor, ndipo mayendedwe ake amadzimadzi amaposa chitsulo kutentha. Ofufuza ochokera ku Beijing University of Chemical Technology aphunzira za matenthedwe a alumina ndi silicon carbide zotsatira zake zikuwonetsa kuti matenthedwe otentha a mphira wa silicone amakula ndikuwonjezeka kwa kuchuluka kwa silicon carbide.Ndi ofanana ndi silicon carbide, matenthedwe otentha a silicon mphira olimbikitsidwa ndi tinthu tating'onoting'ono tating'ono amakhala akulu kuposa kukula kwake .

4. ALN

Aluminiyamu nitride ndi kristalo wa atomiki ndipo imatha kukhalapo motentha pakatentha ka 2200 ℃. Ndi matenthedwe abwino amadzimadzi ndi koyefishienti kakang'ono kowonjezera kwa matenthedwe, ndichinthu chabwino chosagwira kutentha. Matenthedwe otentha a aluminiyamu nitride ndi 320 W · (m · K) -1, yomwe ili pafupi ndi matenthedwe otentha a boron oxide ndi pakachitsulo carbide komanso nthawi zopitilira 5 za alumina.
Ntchito malangizo: matenthedwe silika gel osakaniza dongosolo, matenthedwe dongosolo pulasitiki, matenthedwe epoxy utomoni dongosolo, matenthedwe mankhwala ceramic.

5. AL2O3

Alumina ndi mtundu wa mitundu yambiri yamagetsi yopanda kanthu, yokhala ndi matenthedwe akulu, ma dielectric osasunthika komanso kuvala bwino, omwe amagwiritsidwa ntchito kwambiri popanga zinthu za raba, monga silika gel, potting sealant, epoxy resin, pulasitiki, mphira wamafuta otentha, matenthedwe otentha , mafuta a silicone, ziwiya zoyatsira kutentha ndi zida zina.Mu ntchito yeniyeni, Al2O3 filler itha kugwiritsidwa ntchito payokha kapena kusakanikirana ndi mitundu ina monga AIN, BN, ndi zina zambiri.

6. Mpweya Nanotubes

Kutentha kwamatenda a kaboni nanotubes ndi 3000 W · (m · K) -1, kasanu kopitilira mkuwa. Carbon nanotubes itha kusintha kwambiri matenthedwe azinthu, madutsidwe ndi matupi a mphira, ndipo kulimbitsa kwake ndi kutentha kwake kumatenthedwa kuposa miyambo zodzaza monga mpweya wakuda, mpweya wa kaboni ndi ulusi wamagalasi.
