Thermal conductivity e tlatsitsoe ka mokhoa o ts'oanang ka thepa ea matrix ea mocheso e sebelisang mocheso oa mocheso ho ntlafatsa mocheso oa eona oa mocheso.Ts'ebetso ea ho tsamaisa mocheso e lekanyetsoa haholo-holo ka mocheso oa mocheso (yuniti: W / mk).Thermal conductivity e arotsoe ka polasetiki conductive conductive mocheso le thermal insulation polasetiki.Likarolo tse ka sehloohong tsa conductivity ea mocheso li kenyelletsa lisebelisoa tsa substrate le li-fillers, 'me lisebelisoa tsa substrate li kenyelletsa PPS, PA6 / PA66, LCP, TPE, PC, PPA, PEEK, joalo-joalo;Mocheso o phahameng oa carbon powder, joalo-joalo.
Thermal conductive polasetiki e na le litšobotsi tse latelang:
(1) Ho senya mocheso ka mokhoa o ts'oanang, qoba libaka tse tukang, ho fokotsa deformation ea sebaka se bakoang ke mocheso o phahameng ka lebaka la mocheso o phahameng;
(2) Boima bo bobebe, 40-50% bo bobebe ho feta aluminium;
(3) E loketse ho bōptjoa le ho sebetsa, ha ho na ts'ebetso ea bobeli;
(4) Tekanyo e phahameng ea moralo oa sehlahisoa;
Hobane mokhoa oa ho bopa haholo-holo oa ho bopa, rabara e phalla ka har'a hlobo ka mor'a ho futhumatsa, ebe e pholile.Litšobotsi tsa ts'ebetso ea ts'ebetso li etsa hore mocheso oa mocheso oa thepa o bonts'e litšobotsi tsa batho ba bong bo fapaneng, ke tataiso ea phallo ea sekhomaretsi nakong ea ente le tataiso ea phallo ea sekhomaretsi se otlolohileng.Ka kakaretso, conductivity ea mocheso ka lehlakoreng la phallo ea sekhomaretsi ke makhetlo a 3-6 ho feta a conductivity ea mocheso ka tsela e phallang ea rabara e otlolohileng.Phapang ena e bakoa ke ho kenngoa ha ente ea rabara ha e etsoa habonolo ka tataiso ea phallo.
Bohloeki bo phahameng ba magnesium oxide, bosoeu bo botle, granularity e nyane le ho ts'oana, le decentralization e ntle, e ka sebelisoa bakeng sa conductivity ea mocheso oa filimi ea silicon e futhumetseng, conductivity ea mocheso (PA6, PP, PPS, ABS), joalo-joalo Chelete e ka fihla ho 70- Likarolo tse 80, le sekhahla se phahameng sa ho futhumatsa se ka fihla ho 5W / mk Liphetho li bonts'a hore ha palo ea magnesium oxide e le ka tlase ho likarolo tse 200, tataiso ea mocheso le matla a thata a karoloana e nyane ea magnesium oxide e tlatsang rabara ea silicon e kholo ho feta e kholo. boholo ba likaroloana tsa magnesium oxide, ha sekhahla sa ho otlolla se fapane;boholo ba likaroloana bo fapane;boholo ba karolo e kholo;Magnesium oxide / particle size magnesium oxide le karolelano ea tšebeliso ea rabara ea silicon ho 100/100 ke eona e kholo ka ho fetisisa;Ho eketsa palo e loketseng ea silane coupling agent ho thusa ho eketsa tataiso ea mocheso oa rabara ea silicon.Palo ea magnesium ke 0.5%.Ho PA, PP, PES, eketsa 40-50% magnesium oxide, e ka ntlafatsang haholo conductivity ea mocheso oa polasetiki.
