Pepa Pereti Uku ZTA
Whakaahuatanga Hua
Ko te Ukume Alumina Whakapakari Zirconia, e kiia ana hoki ko te uku ZTA, he mā te tae, he rauemi whakakotahitanga o te waikura konumohe me te 20~25% waikura zirconium. He rauemi hou te Ukume ZTA i whakawhanakehia i ngā tau tata nei.
He whakapainga nui te Chemshun ZTA i te kaha me te pakari o te pānga ki te uku alumina. E 2.5 ngā wā pai ake o te ātete kakahu o Chemshun ZTA i te uku alumina. Ka roa ake te ora o ngā wāhanga o te ZTA, ā, he otinga utu-roa hoki, he tino pai mō ngā taputapu pānga me te kakahu nui o te umanga keri. Ināianei kua whakamahia e te BHP Ahitereiria te nuinga o ngā Raina Uku ZTA.
Āhua me te Momo o ngā Uku ZTA
Ka taea te hanga uku Chemshun ZTA ki te momo uku mania, te momo pewa, te poraka, te rango, te taera hex me ētahi atu.
Ka hangaia hoki ngā wāhanga mīhini motuhake kia rite ki ngā tuhi CAD.
Hei whakamahi pai ake i te ZTA, ka whakamomonahia e mātou te ZTA ki te rapa me te maitai, ka tāutahia he pūtu ki muri o te maitai. Ka tapaina e mātou te whakakotahitanga ko te raina rapa uku ZTA. Ka taea e ngā kaihoko te tāuta ngāwari i te hua ki te papaanga.
Ngā Āhuatanga o ngā Uku Ātete Pānga o ZTA:
He kaha ake te ātete ki te pānga i te alumina teitei
He iti iho te utu i ngā uku zirconia parakore
Ātete kakahu tino pai
Te ātete nui ki te waikura
Te pakari o te whati
Te pumau o te pāmahana teitei
