pa'u alumina lapotopoto
Fa'amatalaga o oloa
O le alumina spherical o se mea e maualuga le faʻatinoina ma le mama maualuga, mea faʻapitoa, maaa maualuga, maualuga le faʻaogaina o le ofuina, maualuga le faʻafefeteina, maualuga le faʻamautuina o le vevela ma le lelei o le eletise eletise.O le alumina spherical e maualuga le maaa ma le malosi, lea e avea ai ma mea e faʻafefeteina lelei.I le fanua o ceramics, mea tau eletise, alamanuia kemikolo ma le fausiaina, alumina spherical e masani ona faʻaaogaina i le gaosiga o mea faʻapipiʻi sima, faʻalava faʻalava faʻafefeteina, vaega afi afi maualuga, ma isi. fa'atumauina le fa'atinoga mautu i si'osi'omaga saua.Mo se faʻataʻitaʻiga, i totonu o le gataifale, vailaʻau vailaʻau, alamanuia malosi ma isi faʻalapotopotoga, alumina spherical e faʻaaogaina i le gaosiga o vaʻa, masini vailaʻau, masini eletise ma isi.Spherical alumina o loʻo i ai le faʻamautuina lelei o le vevela ma le faʻaogaina o le eletise, ina ia mafai ai ona faʻatumauina le lelei o le faʻatinoga i le maualuga o le vevela ma le maualuga o le siosiomaga.I le fanua o mea tau eletise, alumina spherical e faʻaaogaina i le gaosiga o masini eletise eletise maualuga, masini eletise maualuga, ma isi.

Oloa Fa'ailoga
Faʻatumu Maualuga: Tulaga maualuga o le fua faʻatatau o le spheroidization, faʻasalalauina o le tele o vaega faʻapitoa, ausia le maualuga o le faʻatumuina o le silicone ma le epoxy resin, e maua ai le paluga ma le maualalo o le viscosity ma le maualuga;
High Thermal Conductivity: Ona o lona fausaga o le polo toetoe lava a atoatoa, o le faʻatumu o loʻo faʻaaogaina i mea mataʻutia e mafai ona ausia le tele o faʻasalalauga vevela.O le faiga fefiloi atoa o loʻo i totonu o le tulaga o le faʻasalalau lelei, o le mea lea, o oloa faʻaiʻu e sili atu le lelei o le vevela ma mea totino;
Maualalo Abrasion: Faʻatusatusa i le paʻu le masani, o le faʻaogaina o le faʻatumu spherical e mafai ona faʻaitiitia ai le afaina o le paluga, masini faʻapipiʻi ma isi meafaigaluega, ona faʻaumiumi ai lea o le ola galue o meafaigaluega talafeagai.
