Iinzuzo ze-thermal conductivity kunye ne-magnesium oxide

I-conductivity ye-thermal izaliswe ngokufanayo kunye ne-matrix ye-matrix ye-thermal usebenzisa i-conductivity ye-thermal ukuphucula i-thermal conductivity yayo.Umsebenzi wokuqhuba ubushushu ulinganiswa ngokuyintloko nge-thermal conductivity (iyunithi: W / mk).I-Thermal conductivity yahlulwe ibe yiplastiki ye-conductive conductive yobushushu kunye neplastiki yokufakelwa kwe-thermal.Amacandelo aphambili e-thermal conductivity abandakanya izinto ze-substrate kunye nezizaliso, kunye nezixhobo ze-substrate ziquka i-PPS, i-PA6 / PA66, i-LCP, i-TPE, i-PC, i-PPA, i-PEEK, njl.;Ubushushu obuphezulu be-carbon powder, njl.

Iplastiki ye-thermal conductive inezi mpawu zilandelayo:
(1) Ukutshatyalaliswa kobushushu obufanayo, ukuphepha iindawo ezivuthayo, ukunciphisa ukuguqulwa kwendawo okubangelwa ukushisa okuphezulu ngenxa yokushisa okuphezulu;
(2) Ubunzima bokukhanya, i-40-50% ilula kune-aluminium;
(3) Ilungele ukubunjwa kunye nokucubungula, akukho nkqubo yesibini;
(4) Iqondo eliphezulu loyilo lwemveliso;

Ngenxa yokuba indlela yokubumba ubukhulu becala kukubumba, irabha iqukuqela ekubumbeni emva kokufudumeza, emva koko ipholile.Iimpawu zenkqubo yokucubungula zenza i-coefficient yokufudumeza yezinto ezibonisa iimpawu zesini esahlukileyo, oko kukuthi isalathiso sokuhamba kweglue ngexesha lokutofa kunye nolwalathiso lokuhamba ngokuthe nkqo kweglue.Ngokuqhelekileyo, i-thermal conductivity kwicala lokuhamba kweglue ngamaxesha angama-3-6 kune-conductivity ye-thermal kwindlela ehamba ngayo yerubha ethe nkqo.Lo mahluko ubangelwa ukubunjwa kwe-rubber yokutofa xa yenziwe lula kwindlela yokuhamba.

Ukucoceka okuphezulu kwe-magnesium oxide, ubumhlophe obuhle, i-granularity encinci kunye nokufana, kunye ne-decentralization enhle, ingasetyenziselwa ukuhanjiswa kwe-thermal yefilimu ye-silicon ye-thermal, i-thermal conductivity (PA6, PP, PPS, ABS), njl. Isixa sinokufikelela kwi-70- Iingxenye ze-80, kunye neqondo eliphezulu lokufudumeza linokufikelela kwi-5W / mk Iziphumo zibonisa ukuba xa isixa se-magnesium oxide singaphantsi kweengxenye ze-200, isikhokelo sokufudumala kunye namandla okunyamezela kwe-particle encinci ye-magnesium oxide yokuzalisa irabha ye-silicon inkulu kuneyona nkulu. ubungakanani be-particle ye-magnesium oxide, ngelixa izinga lokwelula lichasene;ubukhulu besuntswana elikhulu buchasene;ubukhulu bamasuntswana;I-Magnesium oxide / i-particle encinci ye-magnesium oxide kunye nomlinganiselo wokusetyenziswa kwerubha ye-silicon kwi-100/100 yeyona inkulu;Ukongeza isixa esifanelekileyo se-agent yokudibanisa i-silane luncedo ekwandiseni isikhokelo sokushisa kwerabha yesilicon.Ubungakanani be-magnesium yi-0.5%.Kwi-PA, PP, PES, yongeza i-40-50% ye-magnesium oxide, enokuphucula kakhulu i-thermal conductivity yeplastiki.
