ʻO ka ʻāpana Alumina Ceramic o ka ʻōnaehana kukui
Kahua noi
Hoʻohana nui ʻia nā ʻāpana seramika alumina i ka ʻōnaehana kukui me ka waiwai mechanical kiʻekiʻe, ka paʻakikī kiʻekiʻe, ke ʻaʻahu lōʻihi, ke kūpaʻa insulation nui, ka pale ʻana i ka corrosion maikaʻi, ka pale wela kiʻekiʻe.
Hiki ke hoʻohana ʻia nā ʻāpana seramika alumina i nā kukui a me nā kukui.ʻO ka thermal conductivity o nā alumina ceramic substrates mai ka 29. 3W / (m · K) a hiki i 35W / (m · K), ma kahi o ʻumi a iwakālua mau manawa o nā substrates alumini.Ke hoʻohana ʻia i nā LED, hiki iā lākou ke hana maikaʻi i ka wela a hoʻonui i ke ola o ka LED.Inā hoʻolakoʻia me ka radiator dissipation maikaʻi,ʻaʻole e loaʻa kahi mahana o ka hui, hiki ke hāʻawi i ka palekana kiʻekiʻe no nā pahu kukui .ʻO Kina ka mākeke nui loa o nā'āpana alumina ceramics.ʻO ka hapa nui o ka alumina ceramic i lawe ʻia aku i waho.
Nā kikoʻī
Ka nui koi:1 pc a 1 miliona pcs.ʻAʻohe palena MQQ.
Laʻana manawa alakaʻi:ʻO ka hana hana mea hana he 15 mau lā + hana hoʻohālike 15 lā.
Hana alakai manawa:15 a 45 mau lā.
Uku manawa:kūkākūkā ʻia e nā ʻaoʻao ʻelua.
Kaʻina hana:
ʻO ka alumina (AL2O3) seramika he mea hana ʻenehana nona ka paʻakikī kiʻekiʻe, lōʻihi ke aahu, a hiki ke hana ʻia e ka wili daimana.Hana ʻia ia mai ka bauxite a hoʻopau ʻia e ka hoʻoheheʻe ʻana i ka injection, kaomi ʻana, sintering, wili, sintering a me ka hana machining.
