Pepa Pā keramika ZTA
Wehewehe Huahana
ʻO ka Zirconia Toughened Alumina Ceramic i kapa ʻia hoʻi ʻo ZTA ceramic, he keʻokeʻo ke kala, he mea i hui pū ʻia o ka alumini oxide a me 20 ~ 25% zirconium oxide. He mea hou i hoʻomohala ʻia nā ZTA Ceramics i nā makahiki i hala iho nei.
He hoʻomaikaʻi nui ʻo Chemshun ZTA i ka ikaika a me ka paʻakikī o ka hopena ma luna o ka alumina ceramic. ʻOi aku ka maikaʻi o ke kūpaʻa ʻana o Chemshun ZTA ma mua o ka alumina ceramic i 2.5 mau manawa ma mua o ka alumina ceramic. Hāʻawi ʻo ZTA i ke ola o nā ʻāpana i hoʻonui ʻia a me kahi hopena lōʻihi e ʻoi aku ka maikaʻi o ke kumukūʻai, kūpono loa ia no nā lako hana hopena koʻikoʻi a me ke komo ʻana o ka ʻoihana mining. I kēia manawa ua hoʻohana nui ka BHP Australia i nā ZTA Ceramic Liners.
ʻAno a me ke ʻAno o nā Keramika ZTA
Hiki ke hana ʻia nā keramika Chemshun ZTA i ke ʻano seramika maʻamau, ke ʻano arc, ka cube, ka cylinder, ka tile hex a pēlā aku.
Hoʻolālā pilikino ʻia nā ʻāpana mīkini kūikawā me nā kiʻi CAD.
I mea e hoʻohana pono ai iā ZTA, hoʻopili pinepine mākou iā ZTA i ka laholio a me ke kila a hoʻokomo i nā bolts ma ke kua o ke kila. Ua kapa mākou i ka hui pū ʻana he wear ZTA ceramic rubber liner. Hiki i nā mea kūʻai ke hoʻokomo maʻalahi i ka huahana ma kahi.
Nā Hiʻohiʻona o nā ZTA Wear Impact Resistant Ceramics:
ʻOi aku ka ikaika o ka pale ʻana i ka hopena ma mua o ka alumina kiʻekiʻe
ʻOi aku ka haʻahaʻa o ke kumukūʻai ma mua o nā keramika zirconia maʻemaʻe
Ke kūpaʻa ʻaʻahu kūikawā
Ke kūpaʻa kiʻekiʻe o ka palaho
Paʻakikī haki kiʻekiʻe
Paʻa o ka mahana kiʻekiʻe
