Cas 24304-00-5 Nano Aluminium Nitride AlN poda
Zvimiro zveAlN powder:
AlN poda ine kuchena kwepamusoro, yakatetepa huwandu hwesaizi yekugovera, yakakura chaiyo nzvimbo, yakaderera yakawanda density uye zvirinani kuumba jekiseni rekuumba zvivakwa.2. Aluminium nitride nano powder inoshandiswa mucomposite, uye ine mutsara wakanaka nesilicon semiconductor uye kuwirirana kwayo kwakanaka kunovandudza mechanical properties uye thermal conductivity ye composite zvinhu.
Tsanangudzo yeAlN powder:
| Item | Kuchena | APS | Color | Bulk Density | Crystallographic Fomu | okisijeni yezvinhu | Kugadzira nzira | SSA |
| XL-AlN hupfu | 99% | 50nm | Gireyi | 0.05g/cm3 | Hexagonal chimiro | 0.8% | Plasma CVD | 105m2/g |
Zvishandiso zveAlN poda:
AlN powder inoshandiswa kuvandudza kushanda kwe epoxy resin MuAluminium nitride nanopowder uye epoxy resin system, apo zvinyorwa zveAluminium nitride nanoparticle inosvika ku1% ~ 5%, girazi-shanduko yekushisa inowedzera uye module ye elasticity inosvika pakukosha kwepamusoro.Kuwedzerwa kweAluminium nitride nanopowder kune epoxy resin compound zvinhu zvakasiyana zvachose nekuwedzera kweAluminium nitirde diki zviyo muchimiro.AlN poda inowanzowedzerwa semhando yekusimbisa mumiririri uye inonyanya kugoverwa pakati pemaketani epolymer zvinhu.Kune kusakwana kwekubatana pamusoro pepamusoro uye yakakura chaiyo nzvimbo, AlN hupfu inoratidza basa rakasimba kwazvo.Zvichakadaro, chikamu cheAluminium nitride nanoparticles zviyo zvakagovaniswa mukuparadzaniswa kwepolymer cheni.Kuenzanisa neAluminium nitride diki zviyo, AlN poda ine mvura yakanaka kwazvo uye inogona kuvandudza kusimba, kusimba uye tractility ye epoxy resin.
AlN poda inoshandiswa kupisa conductive zvinhu
Iyo silica gel yakasanganiswa neAlN poda, ine super thermal conductivity, inopa yakanyanya kunaka yekupisa conductivity, magetsi ekudzivirira, yakafara kushanda tembiricha yemagetsi ekudzivirira (-60 ℃ ~ -200 ℃), yakaderera gobvu uye kushanda kwakanaka kwekushanda, uye inogona kuve yakawanda. inoshandiswa mukati mekupisa yekufambisa yepakati yemagetsi chikamu chekuvandudza kushanda zvakanaka, senge CPU radiator filler, yakakwirira-simba audion, inodzoreka Silicon zvikamu, diode, thermal transmission medium musono zvichingodaro.
AlN poda inogona kunyanya kuvandudza kupisa kwepurasitiki.Nekuwedzera Aluminium nitride nanoparticles kupurasitiki zvichienderana nechikamu che5% ~ 10% muhukuru, tinogona kuwedzera kupisa kwepurasitiki kubva ku0.3W/(mk) kusvika ku0.5W/(mk), 16 times more.Kuenzaniswa nekupisa conduction stuffing (alumina kana magnesia) mumusika, inogona kuvandudza michina yezvigadzirwa zvine huwandu hudiki.Parizvino, vagadziri vane hukama vakatenga AlN poda muhuwandu uye iyo itsva-mhando nano kupisa conduction plastiki ichatangwa kumusika.
AlN poda inoshanda zvakanyanya musilicon dioxide uye inowanzopararira murabha.Pasi pechikonzero chekusaita mutsauko kune mechanic kuita kwerabha, (kuyedza kwakaratidza kuti inogona kuvandudza mashandiro erubha), inogona zvakanyanya kuvandudza kupisa kwerubha uye haizodzikisire viscosity semamwe maokisi panguva yekuwedzera maitiro. , uye mari shoma chete inodiwa.Yakave yakashandiswa zvakanyanya kumauto, ndege uye ruzivo engineering.
