Ishidi Lepuleti Le-ZTA Ceramic
Incazelo Yomkhiqizo
I-Zirconia Toughened Alumina Ceramic ephinde yabizwa ngokuthi i-ZTA ceramic, enombala omhlophe, iyinto ehlanganisiwe ye-aluminium oxide kanye ne-zirconium oxide engu-20 ~ 25%. I-ZTA Ceramics iyinto entsha eyakhiwe eminyakeni yamuva nje.
I-Chemshun ZTA iwukuthuthuka okukhulu emandleni okushaya kanye nokuqina kune-alumina ceramic. Ukumelana nokuguguleka kwe-Chemshun ZTA kungcono izikhathi ezingu-2.5 kune-alumina ceramic. I-ZTA inikeza impilo eyengeziwe yezingxenye kanye nesisombululo sesikhathi eside esingabizi kakhulu, ifaneleka kakhulu imishini yokushaya kanye nokuguguleka okukhulu embonini yezimayini. Manje i-BHP Australia isebenzise ama-ZTA Ceramic Liners amaningi.
Ukuma kanye nohlobo lwe-ZTA Ceramics
I-Chemshun ZTA ceramics ingakhiqizwa ibe uhlobo lwe-ceramic olucacile, uhlobo lwe-arc, i-cube, i-cylinder, i-hex tile njll.
Izingxenye ezikhethekile zemishini nazo zenziwe ngezifiso ngemidwebo ye-CAD.
Ukuze sisebenzise kangcono i-ZTA, sivame ukuhlanganisa i-ZTA nerabha nensimbi bese sifaka amabhawodi ngemuva kwensimbi. Sibize le nhlanganisela ngokuthi i-liner yerabha ye-ceramic ye-ZTA egqokwayo. Amakhasimende angafaka umkhiqizo kalula endaweni.
Izici ze-ZTA Wear Impact Resistant Ceramics:
Amandla aphezulu okumelana nomthelela kune-alumina ephezulu
Izindleko eziphansi kakhulu kunezibumba ze-zirconia ezihlanzekile
Ukumelana nokugqokwa okungavamile
Ukumelana nokugqwala okuphezulu
Ukuqina okukhulu kokuphuka
Ukuqina kokushisa okuphezulu
