Spherical Alumina: Inodhura-inoshanda Thermal Conductive Powder Material

Nekukura kwekuputika kweminda-inoda simba senge 5G uye mota nyowani dzesimba, zvinopisa conductivity zvinhu zvichave zvakakosha zvinhu.Semhinduro huru yekuzadza,spherical aluminainoonekwa seyakanyanya kudhura-inoshanda yekupisa poda yekuzadza muindastiri, uye inotarisirwa kutevedzera kukura kwemusika wekupisa wekupisa uye uye kudiwa kuchaputika.

Iwo matatu anowanzo shandiswa mafirita simbi mafirita, kabhoni zvinhu, uye ceramic zvinhu.Kunyangwe simbi mafirita uye kabhoni zvinhu pachazvo zvine yakakwira yekupisa conductivity, iyo inogona kuvandudza zvakanyanya kupisa kwekupisa kwezvinhu zvepolymer, ivo vanowanzo kuvadza zvivakwa zvekudzivirira zvezvinhu zviri pasi pemutoro wakakura.Uye kabhoni zvinhu zvakaita segraphene kana kabhoni nanotubes hazvisi nyore kupararira mumatrix, izvo zvisingakodzeri kuumbwa kweinoshanda thermal conduction nzira.Kuenzaniswa nemhando mbiri idzi dzemafirita, mafirita eceramic akakwezva kutarisisa kwakawanda mumunda wekugadzirira yakakwira yekupisa conductivity macomposites nekuda kweakanakisa ekutamisa kupisa zvivakwa uye yakakwirira yekudzivirira zvivakwa.Pakati pavo,Al2O3 mafirita anoshandiswa zvakanyanya uye nekutsvagirwa nekuda kwekukwirira kwawo kwemafuta ekupisa, yakakwirira resistivity, yakaderera dielectric kurasikirwa, uye kudhura kwekuita.Spherical mafirita anonyanya kubatsira pakushandisa thermal conduction basa re thermally conductive fillers, saka inonyanya kushandiswa thermally conductive filler pamusika inonyanya spherical alumina poda.

Nekuda kwekuita kwayo kwakanaka kwekupisa uye kuita kwemutengo wakanaka, spherical alumina poda ndiyo yekupisa conductivity yekuzadza inoshandiswa muhuwandu mumusika wazvino wemafuta interface zvinhu uye inoverengera chikamu chepamusoro.Thermal interface zvinhu zvinosanganisira thermal gasket, thermal silicone grease, thermal sealing glue uye thermal gel, etc. Iyo terminal inoshandiswa pakupisa kupisa kwezvinhu zvakasiyana-siyana zvemagetsi zvekutaurirana, midziyo yebhatiri yemotokari yemagetsi, zvikamu zvechaja yemagetsi, mwenje we LED, magetsi ekunze. transformers, etc. Uyezve, kudiwa spherical aruminiyamu oxide upfu nokuda thermal aruminiyamu chigadziko mhangura akapfeka ndiro, thermal epurasitiki chisimbiso zvinhu, thermal engineering mapurasitiki (akadai LED mwenje mumvuri, magetsi midziyo, zvemagetsi), thermal spraying coating zvinhu, inokosha. Ceramics, uye zvakakosha zvekukuya zvinhu zviri kuwedzerawo zvishoma nezvishoma.
