I roto i ngā mara ahumahi pēnei i te keri maina, te hiko, te sima, me te whakarewa, ka pāngia tonutia ngā pakitara o roto o ngā taputapu e te pirau nui me te pakaru i puta mai i ngā rerenga rauemi tere-rahi. Ehara i te mea ko tēnei pakaru anake ka arahi ki te kati pinepine o ngā taputapu mō te tiaki, ka nui hoki ngā utu, engari ka taea hoki te whakaweto ohorere, tae atu ki ngā aituā haumaru. Me pēhea te ārai pai i ngā taputapu i te pakaru?Ngā taera uku alumina ātete-mau, me ā rātou mahi tino pai, kua noho hei otinga tino pai i roto i te ao o te ārai-kakahu ahumahi.
Parenga Matua: Te Mahi Tino Pai o ngā Uku Konumohe Waikura
Ko te rauemi matua o ngā taera uku ātete-kakahu he konumohe waikura tino parakore (Al₂O₃), ka whakakāhia ki ngā pāmahana teitei hei hanga i tētahi hanganga uku matotoru me te pakeke-teitei, ka whakawhiwhia ki a ia he ātete kakahu kore e rite. Ko tōna pakeke Mohs he teitei ki te 9 (tuarua ki te taimana anake), he nui ake i te maitai noa, he ngāwari ki te ātete ki te rakuraku me te tapahi i ngā rauemi pakeke pēnei i te onepu kuata, te konganuku, me te paura waro. Heoi anō, he tino pai tōna ātete kakahu me te ātete waikura, ka roa ake te roa o te mahi a ngā taputapu. He maeneene te mata o ngā pereti uku ātete-kakahu, ka whakaiti i te ātete rere o ngā rauemi, ka whakaiti i te whakaputanga wera me te whakapaunga pūngao i te waku, ā, ka ārai pai i te piri me te aukati rauemi.
E tata ana te whakamahi i ngā pereki uku ātete-mau ki ngā taputapu ahumahi katoa e pāngia ana e te waikura me te kakahu o ngā rauemi:
Ngā pūnaha kawe rauemi: ngā paipa waro/paura/pungarehu, ngā paipa maturuturu waro, ngā awaawa, ngā pekepeke, ngā arai takirere, me ētahi atu.
Ngā taputapu tukatuka paura: ngā paipa hau e tomo mai ana, e puta mai ana hoki o ngā kaikohi puehu, ngā wehewehe awhiowhio, ngā pakitara o roto o ngā kaiwhakarōpū paura, ngā hononga tuke o ngā pūnaha kawe hau, me ētahi atu.
Ngā taputapu hiko me te pūngao: ngā putanga mira waro, ngā wehewehe paura mata me ngā mea iti, ngā paipa hau tuatahi, ngā anga whakapūmau o ngā whāngai paura, ngā wāhi pupuhi pungarehu poihau, ngā pūnaha pungarehu me te para, me ētahi atu.
Ngā taputapu keri me te whakarewa: ngā taputapu kuru/wehe/kawe konganuku, ngā tāke wehewehe aukume, ngā paipa para, ngā taputapu whakawera, me ētahi atu.
Ngā taputapu hanga sima: ngā paipa kawe rauemi mata/punga rere/paura waro, ngā mea whakarōpū, ngā mea whakarōpū momo-V, ngā koeko whakamahana-mua, ngā pakitara taha o ngā mīhini whakamatao, me ētahi atu.
Ko ngā taera uku alumina ātete-kakahu, pērā i ngā "ārai pukupuku" i hangaia mō ngā taputapu, me ō rātou pakeke tino pai, ātete-kakahu me ngā āhua rerekē (tapawhā, hexagonal, porowhita), ka hanga he rārangi parepare pakari mō ngā pakitara o roto o ngā taputapu ahumahi.
