Leqephe la Letlapa la Ceramic la ZTA
Tlhaloso ea Sehlahisoa
The Zirconia Toughened Alumina Ceramic hape e bitsoang ZTA ceramic, e leng 'mala o mosoeu, ke motsoako oa thepa ea aluminium oxide le 20 ~ 25% zirconium oxide.ZTA Ceramics ke sesebelisoa se secha se ntlafalitsoeng lilemong tsa morao tjena.
Chemshun ZTA ke ntlafatso e kholo ho matla a tšusumetso le ho tiea holim'a alumina ceramic.Khanyetso ea Chemshun ZTA ke linako tse betere tse 2.5 ho feta alumina ceramic.ZTA e fana ka bophelo bo eketsehileng ba likarolo le tharollo ea nako e telele e theko e boima haholo, e loketse haholo ts'usumetso e feteletseng le lisebelisoa tsa indasteri ea merafo.Hona joale BHP Australia e sebelisitse li-Liner tse ngata tsa ZTA Ceramic
Sebopeho le Mofuta oa ZTA Ceramics
Li-ceramics tsa Chemshun ZTA li ka hlahisoa ka mofuta o hlakileng oa ceramic, mofuta oa arc, cube, cylinder, hex tile joalo-joalo.
Likarolo tse khethehileng tsa mochini le tsona li entsoe ka mokhoa o hlophisitsoeng ka litšoantšo tsa CAD.
E le hore re sebelise molemo oa ZTA, hangata re vulcanize ZTA ho rabara le tšepe ebe re kenya liboutu ka morao ho tšepe.Re bitsitse motsoako e le liaparo tsa ZTA ceramic rabara liner.Bareki ba ka kenya sehlahisoa habonolo sebakeng sa marang-rang.
Likarolo tsa ZTA Wear Impact Resistant Ceramics:
Matla a Phahameng a Thibelo ho Feta alumina e Phahameng
Litsenyehelo tse tlase haholo ho feta li-ceramics tsa zirconia tse hloekileng
Khanyetso e ikhethang ea ho apara
Khanyetso e phahameng ea kutu
Matla a phahameng a fracture
Botsitso bo phahameng ba mocheso
