Cas 24304-00-5 Nano Aluminium Nitride AlN ufa
Makhalidwe a AlN powder:
Ufa wa AlN uli ndi chiyero chachikulu, kugawa kwa tinthu tating'onoting'ono, malo okulirapo enieni, kutsika kochulukira komanso mawonekedwe abwinoko opangira jakisoni.2. Aluminiyamu nitride nano ufa amagwiritsidwa ntchito pophatikizika, ndipo ali ndi mafananidwe abwino ndi silicon ya semiconductor ndipo mawonekedwe ake abwino amalumikizana bwino amawongolera zida zamakina ndi matenthedwe amafuta azinthu zophatikizika.
Kufotokozera kwa AlN powder:
| Kanthu | Chiyero | APS | Mtundu | Kuchulukana Kwambiri | Fomu ya Crystallographic | mpweya wa oxygen | Kupanga njira | SSA |
| XL-AlN ufa | 99% | 50nm pa | Imvi | 0.05g/cm3 | Kapangidwe ka hexagonal | 0.8% | Plasma CVD | 105m2/g |
Kugwiritsa ntchito AlN powder:
AlN ufa ntchito kusintha ntchito epoxy utomoni Mu Aluminiyamu nitride nanopowder ndi epoxy utomoni dongosolo, pamene zili Aluminiyamu nitride nanoparticle kufika 1% ~ 5%, galasi-kusintha kutentha kumawonjezeka ndi gawo la elasticity kufika pazipita mtengo.Kuphatikizika kwa Aluminium nitride nanopowder ku epoxy resin compound materials ndikosiyana kwambiri ndi kuwonjezera kwa Aluminium nitirde njere yaying'ono.AlN ufa nthawi zambiri amawonjezedwa ngati mtundu wa kulimbikitsa wothandizira ndipo makamaka amagawidwa pakati pa maunyolo azinthu za polima.Pakusakanikirana kosakwanira pamtunda ndi malo akuluakulu enieni, ufa wa AlN umasonyeza ntchito yamphamvu kwambiri.Panthawiyi, mbali ya Aluminiyamu nitride nanoparticles njere amagawidwa mu katayanitsidwe wa unyolo polima.Poyerekeza ndi Aluminiyamu nitride timbewu tating'onoting'ono, ufa wa AlN uli ndi madzi abwino kwambiri ndipo ukhoza kupititsa patsogolo mphamvu, kusasunthika ndi kusinthasintha kwa epoxy resin.
AlN ufa ntchito kutentha conductive zakuthupi
Gel silika wophatikizidwa ndi AlN ufa, amene ali wapamwamba matenthedwe madutsidwe, amapereka kwambiri matenthedwe madutsidwe, kutchinjiriza magetsi, lonse ntchito kutentha kutchinjiriza magetsi (-60 ℃ ~ -200 ℃), kutsika makulidwe ndi ntchito bwino ntchito, ndipo akhoza ambiri amagwiritsidwa ntchito pamagetsi otumizira matenthedwe azinthu zamagetsi kuti apititse patsogolo kugwira ntchito bwino, monga chojambulira cha CPU radiator, audion yamphamvu kwambiri, zida zowongolera za Silicon, diode, sing'anga yotumizira matenthedwe mumsoko ndi zina zotero.
AlN ufa amatha kusintha kwambiri matenthedwe matenthedwe apulasitiki.Powonjezera Aluminiyamu nitride nanoparticles ku pulasitiki malinga ndi chiwerengero cha 5% ~ 10% mu misa, tikhoza kuonjezera matenthedwe matenthedwe pulasitiki kuchokera 0.3W/(mk) kuti 0.5W/(mk), 16 nthawi zambiri.Poyerekeza ndi kutentha conduction stuffing (alumina kapena magnesia) mu msika, akhoza kusintha mawotchi zimatha mankhwala ndi ang'onoang'ono kuchuluka.Pakadali pano, opanga ogwirizana agula ufa wa AlN muunyinji ndipo pulasitiki yamtundu watsopano wa nano heat conduction idzakhazikitsidwa pamsika.
AlN ufa umagwira ntchito bwino mu silicon dioxide ndipo umakonda kumwazikana mu rabala.Poganizira kuti palibe kusiyana kulikonse pamakina opangira mphira, (zoyeserera zatsimikizira kuti zitha kuwongolera magwiridwe antchito a rabara), zimatha kusintha kwambiri kutentha kwa mphira ndipo sizingachepetse kukhuthala ngati ma oxides ena pakuwonjezera njira. , ndipo ndalama zochepa kwambiri zimafunika.Zakhala zikugwiritsidwa ntchito kwambiri ku usilikali, kayendetsedwe ka ndege ndi chidziwitso.
