Qhov zoo ntawm thermal conductivity nrog magnesium oxide

Lub thermal conductivity yog uniformly sau nrog thermal matrix khoom siv thermal conductivity los txhim kho nws thermal conductivity.Kev ua tau zoo ntawm cov cua sov yog ntsuas los ntawm thermal conductivity (unit: W / mk).Thermal conductivity yog muab faib ua hluav taws xob conductive yas thiab thermal rwb thaiv tsev yas.Cov khoom tseem ceeb ntawm thermal conductivity muaj xws li cov ntaub ntawv substrate thiab muab tub lim, thiab cov ntaub ntawv substrate muaj xws li PPS, PA6 / PA66, LCP, TPE, PC, PPA, PEEK, thiab lwm yam.;High-heat carbon hmoov, thiab lwm yam.

Thermal conductive yas muaj cov yam ntxwv hauv qab no:
(1) Cov cua kub tsis sib xws, tsis txhob hlawv qhov chaw, txo cov deformation hauv zos los ntawm qhov kub thiab txias vim qhov kub siab;
(2) Lub teeb yuag, 40-50% sib dua li txhuas;
(3) Nws yog qhov yooj yim rau molding thiab ua, tsis muaj kev ua haujlwm thib ob;
(4) Qib siab ntawm cov khoom tsim;

Vim tias txoj kev molding feem ntau yog molding molding, cov roj hmab yog ntws mus rau hauv pwm tom qab cua sov, thiab ces txias.Cov yam ntxwv ntawm kev ua cov txheej txheem ua kom cov cua sov coefficient ntawm cov khoom uas qhia cov yam ntxwv ntawm kev sib deev sib txawv, uas yog cov kev taw qhia ntawm cov kua nplaum ntws thaum txhaj tshuaj thiab cov kev taw qhia ntawm cov kua nplaum ntsug.Feem ntau, cov thermal conductivity nyob rau hauv cov kev taw qhia ntawm cov kua nplaum ntws yog 3-6 lub sij hawm tshaj li ntawm cov thermal conductivity nyob rau hauv ntws kev taw qhia ntawm ntsug roj hmab.Qhov sib txawv no yog tshwm sim los ntawm kev txhaj tshuaj molding ntawm cov roj hmab thaum nws yooj yim tsim nyob rau hauv cov kev taw qhia ntws.

High-purity ntawm magnesium oxide, zoo whiteness, me me granularity thiab uniformity, thiab zoo decentralization, yuav siv tau rau thermal conductivity ntawm thermal silicon zaj duab xis, thermal conductivity (PA6, PP, PPS, ABS), thiab lwm yam. Tus nqi yuav ncav cuag 70- 80 qhov chaw, thiab qhov siab tshaj plaws cua sov tuaj yeem ncav cuag 5W / mk Cov txiaj ntsig tau pom tias thaum cov nyiaj magnesium oxide tsawg dua 200 qhov chaw, cov kev taw qhia thermal thiab tensile lub zog ntawm qhov me me me me magnesium oxide filling silicon roj hmab yog ntau dua qhov loj. particle loj ntawm magnesium oxide, thaum lub stretching tus nqi yog qhov opposite;qhov loj particle loj yog qhov opposite;qhov loj particle loj;Magnesium oxide / me me qhov loj me magnesium oxide thiab kev siv piv ntawm silicon roj hmab ntawm 100/100 yog qhov loj tshaj plaws;Ntxiv qhov tsim nyog tus nqi ntawm silane coupling tus neeg sawv cev yog qhov tsim nyog los ua kom cov thermal taw qhia ntawm silicon roj hmab.Cov ntsiab lus ntawm magnesium yog 0.5%.Hauv PA, PP, PES, ntxiv 40-50% magnesium oxide, uas tuaj yeem txhim kho cov thermal conductivity ntawm yas zoo heev.
