Iphepha lePlate yeCeramic yeZTA
Ingcaciso yeMveliso
I-Zirconia Toughened Alumina Ceramic ekwabizwa ngokuba yi-ZTA ceramic, enombala omhlophe, yinto edibeneyo ye-aluminium oxide kunye ne-20 ~ 25% zirconium oxide. I-ZTA Ceramics yinto entsha eyenziwe kwiminyaka yakutshanje.
I-Chemshun ZTA iphucuke kakhulu kumandla okuchaphaza kunye nokuqina kune-alumina ceramic. Ukumelana nokuguguleka kwe-Chemshun ZTA kubhetele ngokuphindwe kayi-2.5 kune-alumina ceramic. I-ZTA inika ubomi obuphuculweyo bezinto kunye nesisombululo sexesha elide esingabizi kakhulu, ifanelekile kakhulu kwizixhobo zokuchaphaza kakhulu kunye nokuguguleka kwishishini lemigodi. Ngoku i-BHP Australia isebenzise uninzi lwee-ZTA Ceramic Liners.
Imo kunye nohlobo lwee-ZTA Ceramics
Iiseramikhi zeChemshun ZTA zingenziwa zibe yiseramikhi ecacileyo, uhlobo lwe-arc, ityhubhu, isilinda, ithayile ye-hex njl.
Iindawo ezikhethekileyo zoomatshini nazo zenziwe ngokwezifiso ngemizobo yeCAD.
Ukuze sisebenzise i-ZTA ngcono, sidla ngokuyixuba i-ZTA ibe yirabha kunye nentsimbi size sifake iibholithi ngasemva kwentsimbi. Le ndibaniselwano siyibize ngokuba yi-ZTA ceramic rubber liner enxitywayo. Abathengi banokuyifaka lula imveliso kwindawo leyo.
Iimpawu zeZTA Wear Impact Resistant Ceramics:
Amandla aphezulu okumelana nempembelelo kune-alumina ephezulu
Ixabiso eliphantsi kakhulu kune-zirconia ceramics yobumsulwa
Ukumelana nokuguguleka okungaqhelekanga
Ukumelana nokugqwala okuphezulu
Ukuqina okukhulu kokuqhekeka
Uzinzo lobushushu obuphezulu
