alumina alakaʻi wela

ʻO ka mea hoʻopihapiha hoʻoili wela e like me kona inoa e hōʻike nei ua hoʻohui ʻia i loko o ka mea matrix i hoʻohana ʻia e hoʻonui i ka conductivity thermal o ka mea hoʻopihapiha, ka mea hoʻopihapiha hoʻoili wela i hoʻohana pinepine ʻia ʻo alumina, magnesium oxide, zinc oxide, alumini nitride, boron nitride, silicon carbide, etc. I waena o lākou, ʻoiai ʻo micron alumina, silicon powder ma ke kino nui. ʻO ke ʻano o ka alumina he mana nui i ka conductivity thermal o alumina. ʻO ka pauka ultrafine alumina poepoe he pauka micron, me ka conductivity thermal kiʻekiʻe, ka insulation kiʻekiʻe, ka paʻakikī kiʻekiʻe, ke kū'ē ʻana i ka mahana kiʻekiʻe, ke kū'ē ʻana i ka abrasion, ke kū'ē ʻana i ka corrosion, a me nā ʻano ʻē aʻe; Maʻemaʻe kiʻekiʻe, ke ʻano maikaʻi, ke kūpaʻa maikaʻi, ka hoʻokaʻawale ʻana o ka nui o nā ʻāpana haiki, me ka liʻiliʻi o ka hoʻopiha e loaʻa ai ka conductivity thermal kiʻekiʻe. Hoʻolauna i ka alumina conductive thermal: ʻo ka alumina conductive thermal he kristal pauka keʻokeʻo i hana ʻia ma lalo o ke kiʻekiʻe wela. Nui nā pauka crystalline o ka alumina, akā ʻo ka alumina i hoʻohana ʻia no ka hoʻoili wela e komo pū me ka alumina spherical (zf-kq series), spherical alumina (zf-kk series), composite alumina (zf-kqm, KCM series), etc. Pono ka alumina conductive thermal i nā ʻano o ka hoʻolaha nui o nā ʻāpana haiki, ka paʻa maikaʻi o ka nui o nā ʻāpana, ka waiwai conductivity thermal kiʻekiʻe K a me ka nui o nā ʻāpana hoʻopiha ma hope o ka hoʻololi ʻana o ka hoʻopili ʻana. Ma keʻano laulā, hiki ke hoʻomalu ʻia ka nui o nā ʻāpana awelika o ka alumina hoʻokele wela ma kahi o 5um, a hiki i ka conductivity thermal ke hiki ma waena o 3-10w /mk e like me ka nui o ka hoʻopiha ʻana.
