Zvishandiso zvepolymer zvine mabhenefiti ehushoma density, kugadzirwa kuri nyore, uye yakanaka yekuvharisa magetsi.Iwo anoshandiswa zvakanyanya muminda senge microelectronics kubatanidzwa uye kurongedza, michina yemagetsi, uye LED kuchengetedza simba.Kazhinji kutaura, mapolymers akashata maconductor ekupisa.Nezve ma insulating zvinhu, simba ravo rekupisa kupisa rave kuita dambudziko remabhodhoro, uye pane kudiwa kwekukurumidzira kugadzirira yakakwira yekupisa yekupisa polymer composite zvinhu zvine yakanakisa yakazara zvivakwa.

Silicon carbide ine maitiro ekudzivirira kupisa, kupisa kwekushisa kwepamusoro, kusimba kwepamusoro, kunaka kwekushisa kwekushisa, kukanganisa kupikisa, etc. Panguva imwecheteyo, ine zvakanakira high thermal conductivity, oxidation resistance, uye kunaka kwekushisa kwekushisa.

Vatsvakurudzi vakashandisa silicon carbide sechinhu chinopisa chinogadzirisa kuzadza epoxy, uye vakaona kuti nano-silicon carbide inogona kusimudzira kurapwa kwe epoxy resin, uye silicon carbide particles zvinowanzoita nzira yekupisa kana kupisa network chain mukati me resin system. , kuderedza yemukati void ratio ye epoxy resin uye kuvandudza epoxy resin.Iyo mechanical uye thermal conductivity yezvinhu.

Zvimwe zvidzidzo zvakashandisa silane coupling agent, stearic acid uye kusanganiswa kwavo semagadzirirwo ekudzidza migumisiro yezvakasiyana-siyana zvinogadzirisa pane zvakasimba, mafuta absorption value uye thermal conductivity ye β-SiC powder.Mhedzisiro yekuedza inoratidza kuti shanduko yeKH564 mune silane coupling agent inonyanya kuoneka;kuburikidza nekudzidza kwe stearic acid uye kusanganiswa kwemaviri epamusoro ekugadzirisa, zvigumisiro zvinoratidza kuti kuchinja kwekugadzirisa kunowedzera kuvandudzwa kana kuenzaniswa nekugadzirisa imwe chete, uye kuoma kwakakwirira.Mhedzisiro yemafuta acid uye KH564 iri nani, uye kupisa kwekushisa kunosvika 1.46 W / (m · K), iyo 53.68% yakakwirira kudarika iyo isina kuchinjwa β-SiC uye 20.25% yakakwirira kudarika imwe chete KH564 kugadziriswa.

Pamusoro pereferensi yako chete, ruzivo rwaizoda kuongororwa kwako, ndatenda.
