Alumina Ceramic Vaega o Faʻamalama
Talosaga Field
Alumina ceramics vaega o loʻo faʻaaogaina lautele i le faʻamalamalamaina o le faʻaogaina o mea faʻainisinia maualuga, maualuga le maaa, umi le ofuina, tele faʻafefete puipui, puipuia lelei le pala, maualuga le vevela.
E mafai ona fa'aogaina vaega fa'amalama alumina i moli ma moli.O le faʻafefeteina o le alumina ceramic substrates e amata mai i le 29. 3W / (m · K) i le 35W / (m · K), lea e tusa ma le sefulu i le luasefulu taimi o mea alumini.A faʻaoga i LED, e mafai ona latou faʻatautaia lelei le vevela ma faʻateleina le ola o le LED.Afai e faʻapipiʻiina i se faʻamalo vevela vevela lelei, o le a leai se vevela faʻatasi i mea uma, lea e mafai ona maua ai le puipuiga maualuga mo le lamepa .China o le maketi sili ona tele o vaega alumina ceramics.o le tele o alumina ceramic e auina atu i fafo.
Fa'amatalaga
Aofaiga mana'omia:1pc i le 1 miliona pcs.E leai se MQQ fa'atapula'aina.
Taimi fa'ata'ita'i:faia meafaigaluega e 15 aso + faia faataitaiga 15 aso.
Taimi ta'i gaosiga:15 i le 45 aso.
vaitaimi totogi:soalaupule e itu e lua.
Fa'agasologa o gaosiga:
Alumina (AL2O3) ceramic o se fale gaosi oloa e maualuga le maaa, umi le ofuina, ma e mafai ona faia e ala i le olo taimane.O loʻo gaosia mai le bauxite ma faʻamaeʻaina e tui tui, faʻapipiʻi, sintering, olo, sintering ma masini.
