Kua noho ngā uku matatau hei rauemi nui mō te hanga ahumahi hou. Mai i ngā taputapu hanga haurua-ira me ngā mīhini tino tika ki ngā taputapu hauora me ngā pūnaha whakawhitiwhiti kōrero whatu, kei te piki haere te whakamahinga o ngā wāhanga uku i roto i ngā tono e kore ai e taea e ngā konganuku me ngā kirihou tuku iho te whakarato i te ātete kakahu, te pumau matū, te whakamarumaru hiko, te mahi ā-ahu rānei.
Ko te alumina (Al₂O₃) me te zirconia (ZrO₂) tētahi o ngā rauemi uku matatau e whakamahia whānuitia ana. He tino pai ngā āhuatanga miihini me te ātete matū o ēnei e rua, engari he rerekē ngā āhuatanga mahi. Mā te whiriwhiri i te rauemi hē ka raru wawe te wāhanga, ka nui ngā utu hanga koretake, ka uaua rānei i te wā e miihini ana me te huihuinga.
Nā, ko tēhea rauemi te mea pai ake mō ngā wāhanga uku tino tika: te alumina, te zirconia rānei?
Ko te whakautu kei runga i te taiao mahi, te kawenga miihini, ngā whakaritenga rahinga, me te roa o te ratonga e tumanakohia ana. E whakamārama ana tēnei aratohu i ō rātou rerekētanga, ā, e whakarato ana hoki i ngā whakaaro hangarau mahi mō te whiriwhiri rauemi.
1. He aha te uku konumohe?
Ko te uku alumina, e mōhiotia ana i roto i te matū ko te waikura konumohe (Al₂O₃), tētahi o ngā rauemi uku hangarau e whakamahia whānuitia ana i roto i ngā mahi hanga ahumahi.
E whakanuia ana mō tōna pakari, te ārai hiko, te ātete ki te kakahu, te ātete ki te waikura, me te pumau ki te pāmahana tiketike.
Kei te wātea te Alumina i ngā taumata parakore rerekē, tae atu ki ngā hanganga e whakamahia whānuitia ana ko te 95%, 96%, 99%, me ngā hanganga parakore teitei ake. Ka pā te parakore me te hanganga o ngā rauemi ki ngā āhuatanga miihini, hiko, me te wera whakamutunga.
Ko ngā tono noa ko:

E whakaarohia ana hoki te alumina parakore-teitei mō ngā taputapu haurua-ira nā tōna pakeke, tōna pumau matū, me tōna kaha ki te tu atu ki ngā taiao tukanga uaua. Heoi, me manatoko te pai o tētahi taumata motuhake ki ngā whakaritenga matū tukanga me te poke tuturu.
2. He aha te Uku Zirconia?
Ko te uku zirconia, ko te zirconium dioxide rānei (ZrO₂), tētahi atu rauemi uku matatau nui.
He rerekē ki te alumina, e mōhiotia whānuitia ana te zirconia mō tōna pakari pakaru teitei i waenga i ngā uku waikura. E pā ana tēnei āhuatanga ki te pakari whakawhiti i roto i ngā hanganga zirconia kua whakapumautia tika.
I runga i te hanganga, ka taea e te zirconia te whakarato:
- Te kaha piko teitei
- He pakari pai mō te whati
- He ātete kakahu pai rawa atu
- He ātete pai ki te waikura
- Te kawe wera iti
- Ngā āhuatanga whakaoti mata pai
Ko te Yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) he rauemi zirconia hangarau e whakamahia whānuitia ana.
He pai te zirconia mō ngā wāhanga tika e pāngia ana e te utaina ā-mīhini auau, te pahekeheke, ngā āhuatanga rānei e hira ai te ātete ki te horapa o te kapiti.
Ko ngā whakamahinga noa ko ngā wāhanga miihini tino tika, ngā wāhanga ātete-kakahu, ngā wāhanga uku e pā ana ki te hauora, me ngā wāhanga hanganga ahumahi motuhake.
Heoi, kāore te zirconia i te tino pai ake i te alumina. Me whai whakaaro anō hoki ki ōna āhuatanga wera, te utu rauemi, te pūnaha pumau, me te aro ki ētahi āhuatanga taiao.
3. Alumina me te Zirconia: Ngā Rerekētanga Matua o te Mahi
