Uru nke thermal conductivity na magnesium oxide

The thermal conductivity na-ejupụta n'otu n'otu na ihe matriks thermal na-eji thermal conductivity na-eme ka ọ dị mma.A na-atụkarị arụmọrụ conduction okpomọkụ site na thermal conductivity (otu: W/mk).Thermal conductivity na-ekewa n'ime okpomọkụ conductive plastic na thermal mkpuchi plastik.Ihe ndị bụ isi nke conductivity thermal gụnyere ihe ndị na-emepụta ihe na ihe ndị na-emepụta ihe, na ihe ndị na-emepụta ihe gụnyere PPS, PA6/PA66, LCP, TPE, PC, PPA, PEEK, wdg;Elu-okpomọkụ carbon ntụ ntụ, wdg.
