Leqephe la Poleiti ea ZTA Ceramic
Tlhaloso ea Sehlahisoa
Zirconia Toughened Alumina Ceramic e boetse e bitsoa ZTA ceramic, e leng 'mala o mosoeu, ke motsoako oa aluminium oxide le 20 ~ 25% zirconium oxide. ZTA Ceramics ke thepa e ncha e ntlafalitsoeng lilemong tsa morao tjena.
Chemshun ZTA ke ntlafatso e kholo matleng a tshusumetso le ho tiea ha ceramic ea alumina. Khanyetso ea ho tsofala ea Chemshun ZTA e betere ka makhetlo a 2.5 ho feta ceramic ea alumina. ZTA e fana ka bophelo bo eketsehileng ba likarolo le tharollo ea nako e telele e theko e tlaase, e loketse haholo bakeng sa lisebelisoa tse matla tsa tshusumetso le ts'ebetso indastering ea merafo. Hona joale BHP Australia e sebelisitse li-ZTA Ceramic Liners tse ngata.
Sebopeho le Mofuta oa Li-ceramics tsa ZTA
Liserame tsa Chemshun ZTA li ka hlahisoa ka mofuta o se nang letho oa ceramic, mofuta oa arc, cube, silindara, hex tile jj.
Likarolo tse khethehileng tsa mechini le tsona li etselitsoe ka mokhoa o ikhethileng ka litšoantšo tsa CAD.
E le ho sebelisa ZTA hamolemo, hangata re kopanya ZTA le rabara le tšepe ebe re kenya liboutu ka morao ho tšepe. Re e bitsitse motswako ona e le ho roala ZTA ceramic rabara liner. Bareki ba ka kenya sehlahisoa habonolo sebakeng seo.
Likarolo tsa Li-ceramics tse sa Khaotseng ho Tshoaroa ke ZTA:
Matla a Phahameng a Hanelang Tšusumetso ho feta Alumina e Phahameng
Litšenyehelo tse tlase haholo ho feta li-ceramics tsa zirconia tse hloekileng
Khanyetso e ikhethang ea ho roala
Ho hanyetsa ts'enyeho e phahameng
Ho thatafala ha ho robeha ho hoholo
Botsitso ba mocheso o phahameng
