Raina Whakamau Ukume Rapa ZTA
Kupu Whakataki:
Ka taea te whakamomona i ngā momo āhua uku ZTA ki roto i ngā rau rapa, kia ngāwari ai te whakamahi a ngā kiritaki, kia iti ai hoki te pakaru o ngā wāhanga. Ko te tikanga he pai te whakamahi i tā mātou hua i roto i te whānuitanga o ngā tono, mai i ngā awaawa me ngā hopara ki ngā pūnaha kawe me ngā rohe pānga.
He tere, he māmā hoki te tāutanga o tā mātou pereti kakahu, nā te tikanga pūtu, te tikanga whakarewa rānei ka taea te whakamahi. Mā tēnei ka whakaitihia te wā whakatā, ā, ka tiakina ō taputapu i te wā e taea ai. He teitei hoki te ātete o tā mātou pereti kakahu uku rapa ki te pakū, e whakarite ana ka taea e ia te tu atu ahakoa ngā āhuatanga tino kino me te pupuri tonu i tōna whai huatanga.
Āhuatanga
He kaha ake i te alumina
He iti ake te utu i te zirconia
Ātete kakahu tino pai
Te ātete nui ki te waikura
Te pakari o te whati
Te pumau o te pāmahana teitei
Painga
E whakamahia ana ngā arai uku rapa ātete ki te kakahu hei whakarato i te tiaki nui ake i te kakahu me te pānga.
1) Whakakotahitia te rapa mimiti pūngao me te uku alumina teitei ātete ki te pakū, he pai mō ngā mahi kakahu me te pānga nui.
2) He āhua me he rahi ritenga hei whakatutuki i ō hiahia motuhake, kei te wātea katoa ngā raina paerewa me ngā mea kāore i te paerewa.
3) Ngā otinga katoa mō te kakahu me te pakū
4) Kaihanga me te wheako nui, he pai te hononga i waenga i te rapa me te uku, ka noho tonu ngā uku ki tōna tūranga tae noa ki te pakaru katoa.
5) He whānuitanga o ngā pereti kakahu uku rapa hei whakatutuki i ō hiahia rerekē.
Tono
