Izinzuzo conductivity ezishisayo nge magnesium oxide

I-thermal conductivity igcwaliswa ngokufanayo ngezinto ze-matrix ezishisayo zisebenzisa i-thermal conductivity ukuze kuthuthukiswe ukuqhutshwa kwayo kwe-thermal.Ukusebenza kokwenziwa kokushisa kukalwa ngokuyinhloko nge-thermal conductivity (iyunithi: W/mk).I-thermal conductivity ihlukaniswe ngepulasitiki yokushisa eqhubayo kanye nepulasitiki yokushisa eshisayo.Izingxenye eziyinhloko ze-thermal conductivity zihlanganisa izinto ze-substrate kanye nama-filler, futhi izinto ze-substrate zihlanganisa i-PPS, i-PA6/PA66, i-LCP, i-TPE, i-PC, i-PPA, i-PEEK, njll.;I-carbon powder yokushisa ephezulu, njll.

Ipulasitiki ye-thermal conductive inezici ezilandelayo:
(1) Ukuchithwa kokushisa okufanayo, gwema izindawo ezivuthayo, ukunciphisa ukuguquguquka kwendawo okubangelwa izinga lokushisa eliphezulu ngenxa yokushisa okuphezulu;
(2) Isisindo esilula, 40-50% silula kune-aluminium;
(3) Ilungele ukubunjwa nokucubungula, akukho ukucubungula okwesibili;
(4) Izinga eliphakeme lokuklama umkhiqizo;

Ngenxa yokuthi indlela yokubumba iwukubumba ngokuyinhloko, irabha igelezela esibunjeni ngemva kokushisa, bese ipholiswa.Izici zenqubo yokucubungula zenza i-coefficient yokushisa yezinto ezibonisa izici zobulili obuhlukile, okungukuthi isiqondiso sokugeleza kweglue ngesikhathi sokujova kanye nesiqondiso sokugeleza kweglue eqondile.Ngokuvamile, i-thermal conductivity in the direction of the glue flow flow is 3-6 izikhathi kunaleyo ye-thermal conductivity in the flowing direction of rubber mpo.Lo mehluko ubangelwa ukubunjwa kokujova kwenjoloba lapho kwakheka kalula ekuqondeni kokugeleza.

Ukuhlanzeka okuphezulu kwe-magnesium oxide, ubumhlophe obuhle, i-granularity encane kanye nokufana, kanye nokusabalalisa okuhle, kungasetshenziselwa ukuqhutshwa kokushisa kwefilimu ye-silicon eshisayo, i-thermal conductivity (PA6, PP, PPS, ABS), njll. Inani lingafinyelela ku-70- Izingxenye ezingama-80, kanye nezinga lokushisa eliphakeme kakhulu lingafinyelela ku-5W/mk Imiphumela ibonisa ukuthi lapho inani le-magnesium oxide lingaphansi kwezingxenye ezingama-200, isiqondiso esishisayo namandla aqinile wezinhlayiyana ezincane ze-magnesium oxide egcwalisa irabha ye-silicon inkulu kunenkulu. usayizi wezinhlayiyana ze-magnesium oxide, kuyilapho izinga lokwelula liphambene;ubukhulu bezinhlayiyana ezinkulu buphambene;ubukhulu bezinhlayiyana;I-Magnesium oxide/usayizi wezinhlayiyana ezincane ze-magnesium oxide kanye nesilinganiso sokusetshenziswa kwerabha ye-silicon ku-100/100 yiyona enkulu kunazo zonke;ukwengeza inani elifanele le-ejenti yokuhlanganisa i-silane kusiza ekwandiseni isiqondiso esishisayo serabha ye-silicon.Inani le-magnesium liyi-0.5%.Ku-PA, PP, PES, engeza i-40-50% ye-magnesium oxide, engathuthukisa kakhulu ukuqhutshwa kokushisa kwepulasitiki.
