ifu ya alumina
Ibisobanuro ku bicuruzwa
Spherical alumina ni ibikoresho bikora cyane bifite isuku ryinshi, ibice bya serefegitire, ubukana bwinshi, birwanya kwambara cyane, birwanya ruswa nyinshi, ituze ryinshi ryumuriro hamwe n’amashanyarazi meza.Spherical alumina ifite ubukana nimbaraga nyinshi, bigatuma iba ibikoresho byiza birinda kwambara.Mu bijyanye n’ubutaka, ibikoresho bya elegitoroniki, inganda z’imiti n’ubwubatsi, alumina spherical ikoreshwa cyane mu gukora ibikoresho by’ubutaka bwateye imbere, ibyuma bitarinda kwambara, ibyuma bya moteri bigezweho, n'ibindi. komeza imikorere ihamye mubidukikije bikaze.Kurugero, mubidukikije bya Marine, inganda zimiti, inganda zingufu nizindi nzego, alumina spherical ikoreshwa mugukora amato, ibikoresho bya shimi, ibikoresho byamashanyarazi nibindi.Spherical alumina ifite ubushyuhe bwiza nubushyuhe bwamashanyarazi, kugirango ibashe gukomeza imikorere myiza mubushyuhe bwinshi hamwe n’umuvuduko mwinshi.Mu rwego rwa elegitoroniki, alumina spherical ikoreshwa mugukora ibikoresho bya elegitoroniki yubushyuhe bwo hejuru, ibikoresho byamashanyarazi menshi, nibindi.

Ibiranga ibicuruzwa
Kwuzura kwinshi: Urwego rwo hejuru rwikigereranyo cya spheroidisation, igabanywa ryingero zingana kugabanywa, kugera kubucucike bwinshi bwuzuza silicone na epoxy resin, kugirango ubone imvange hamwe nubukonje buke kandi bigenda cyane;
Ubushyuhe bwo hejuru bwa Thermal: Kubera imiterere yumupira hafi ya yose, uwuzuza akoreshwa mubikoresho fatizo arashobora kugera kubushyuhe bwinshi.Sisitemu yose ivanze iri muburyo bwiza bwo gutatanya, ibicuruzwa byanyuma rero bifite ubushyuhe bwiza bwumuriro nibintu byumubiri;
Abrasion Ntoya: Ugereranije nifu idasanzwe, ikoreshwa ryuzuza sherfike rishobora kugabanya gukuramo imvange, imashini zibumba nibindi bikoresho, hanyuma bikongerera igihe cyakazi cyibikoresho bijyanye。
