Icwecwe lePleti yeCeramic ye-ZTA
Ingcaciso yeMveliso
I-Zirconia Toughened Alumina Ceramic ikwabizwa ngokuba yi-ZTA ceramic, enombala omhlophe, yinto edibeneyo ye-aluminium oxide kunye ne-20 ~ 25% ye-zirconium oxide.I-ZTA Ceramics yinto entsha ephuhliswe kwiminyaka yakutshanje.
I-Chemshun ZTA luphuculo olubonakalayo kumandla empembelelo kunye nokuqina kwi-alumina ceramic.Ukumelana nokunxiba kwe-Chemshun ZTA ngama-2.5 amaxesha angcono kune-alumina ceramic.I-ZTA ibonelela ngokwandisa ubomi becandelo kunye nesisombululo esisebenzayo sexesha elide, ifanelekile kakhulu kwiimpembelelo ezigqithisileyo kunye nokunxiba izixhobo zoshishino lwemigodi.Ngoku i-BHP yase-Australia isebenzise i-ZTA Ceramic Liners ezininzi
Ubume kunye nohlobo lweeCeramics zeZTA
I-Chemshun ZTA ceramics inokuveliswa ibe yi-ceramic plain type, uhlobo lwe-arc, ityhubhu, isilinda, i-hex tile njl.
Iinxalenye zoomatshini ezikhethekileyo nazo zilungiselelwe ngokwemizobo yeCAD.
Ukuze sithathe ithuba elingcono le-ZTA, sihlala sivuthela i-ZTA kwi-rubber kunye nentsimbi kwaye sifake iibholithi ngasemva kwentsimbi.Abathengi banokufaka lula imveliso kwisiza.
Iimpawu ze-ZTA Wear Impact Resistant Ceramics:
Amandla okumelana neMpembelelo ephezulu kune-alumina ephezulu
Ixabiso eliphantsi kakhulu kune-iceramics ye-zirconia yobunyulu
Ukumelana nokunxiba okungaqhelekanga
Ukumelana nomhlwa okuphezulu
Ukuqina kokwaphuka okuphezulu
Uzinzo oluphezulu lobushushu
