Tauira Koreutu mō te Ahumahi Hanga Rino Maka Rino kua Whakamahia mō ngā Pereki Ringihia Papa Pūngāwerewere Bauxite/Mullite Alumina Teitei
Ko tā mātou mahi he hono tonu ki tā mātou kaupapa matua "Kaihoko tuatahi, Whakawhirinaki ki te tuatahi, me te arotahi ki ngā takai kai me te haumaru taiao mō te katoa."Pereki Whakamātao me te Oumu Pereki, He aha mātou ka taea ai ēnei? Nā te mea: A, He pono, he pono hoki mātou. He kounga teitei ā mātou taonga, he utu ātaahua, he rawaka te kaha tuku me te ratonga tino pai. B, He painga nui tō mātou tūnga whenua. C, Ngā momo rerekē: Nau mai ki tāu patai, Tērā pea ka tino maioha koe.
Ngā pereki maitai rereE pā ana ki ngā pereki ātete-kore e whakatakotoria ana ki roto i ngā awaawa o te pereti raro whakarewa ingot hei hono i ngā pereki maitai rere me te pokepoke ingot, e mōhiotia whānuitia ana ko te pereki oma. E whakamahia ana hei whakaiti i te ātete o te rere o te maitai rewa me te ārai i te turuturu o te maitai. Ko ngā āhuatanga matua ko te ātete ki te pēhanga pāmahana teitei, te ātete ki te kakahu, te rere pai, te ngāwari o te tāutanga me te ātete ahi pai.
1. Whakarōpūtanga mā te rauemi：
(1)Uku:Koinei te momo pereki maitai rere tino taketake, he mea hanga ki te uku noa. Ahakoa he iti te utu, he iti te ātete ki te ahi me te roa o te mahi, ā, he pai mō ētahi mira maitai iti, mō ngā whakamahinga rangitahi rānei.
(2) Konumohe teitei:He nui te konumohe kei roto i tēnei pereki maitai rere, he tino ātete ki te ahi, ā, ka taea te noho pumau i roto i ngā taiao pāmahana teitei. He maha ngā wā ka whakamahia i roto i ngā umanga maitai nui, inā koa i roto i ngā tukanga hanga maitai e hiahia ana kia tu atu i ngā pāmahana teitei mō te wā roa.
(3)Multite:He hanganga whatunga whakawhiti ngā tioata āhua ngira o te mata, ā, ka taea te ārai i te horo o te maitai rewa. Koinei te rauemi matua i tēnei wā.
2. Whakarōpūtanga mā te mahi:
(1)Pereki Waenganui
Whakamahia i roto i te rohe matua o te rere o te maitai rewa, hei tautoko i te ara rere me te hiahia kia nui te kaha
te ātete ki te pirau me te ātete ki te pakū.
(2)Pereki Wehewehe Rino
Hei huri i te maitai rewa ki ngā pokepokea rerekē. Ko ngā whakaritenga noa ko ngā kōhao takirua, takitoru, me te whā, i runga i ngā whakaritenga tukanga.
(3) Ngā Pereki Hiku
Kei te pito o te pūnaha rere maitai, ka tu atu rātou i te pānga o te maitai rewa me ngā pāmahana tiketike, ā, me ātete hoki ki te pakaru.
1. Ātete pāmahana teitei
Ka taea e rātou te tu atu i te pāmahana tino nui o te maitai rewa i waenganui i te 1500–1700℃ mō ngā wā roa. Hei tauira, ko ngā pereki whakarewa mullite he ātete ki te neke atu i te 1780℃, he pai mō ngā mahi whakarewa pāmahana teitei.
2. Ātete kaha ki te horo
He matotoru, he kaha hoki te hanganga, ā, ka taea e ngā pereki whakarewa te ātete i te horoinga tinana e puta mai ana i te rere tere o te maitai rewa, ka whakaiti i te pakaru me te haehae i te wā e whakamahia ana.
3. Ātete pai ki te waikura
Ka taea e rātou te ātete ki te horo matū mai i te maitai rewa me ngā momo para. He rerekē ngā hanganga rauemi kua whakarerekētia ki ngā āhuatanga mahi motuhake.
4. He ātete pai ki te ru wera
Ka taea e rātou te tu atu i ngā piki me ngā heke tere o te pāmahana i te wā e whakarewaina ana, me te kore e ngatata, e pakaru rānei.
5. He iti te poke o te maitai rewa
Ka whakaitihia te kiri me te maturuturunga o ngā matūriki e te hanganga matotoru o te rauemi, ka ārai i te whakaurunga o ngā poke ki roto i te maitai rewa, ā, ka whakarite hoki i te parakore me te kounga o ngā hua maitai whakamutunga.
6. Te tika o te ine i ngā āhuatanga
He maeneene ngā awa o roto, he rite ngā āhua o waho, ā, he kikī ngā ātete āhua. Mā tēnei ka kore he hononga i te wā tāutanga, ka whakaiti i te ātete rere o te maitai rewa, ā, ka ārai i ngā tūponotanga turuturu maitai.

Ngā pereki maitai reree whakamahia nuitia ana i roto i te tukanga whakarewa o raro, hei awa e rere ai te maitai rewa mai i te koko ki ngā pokepokea ai, kia pai ai te tohatoha o te maitai rewa ki ia pokepokea ai.
Mahi Matua
Mā ngā pereki maitai rere, mā roto i ō rātou roto tuwhera, ka whakarite kia rere te maitai rewa ki te taha matau, kia kore ai e pā tika ki ngā pokepokea ai, kia iti ai hoki te pakaru o te hanganga nā te wera nui o te wāhi. Hei tāpiri, mā ō rātou āhuatanga ātete ka taea e rātou te tu atu ki ngā pānga ā-tinana me ngā tauhohenga matū o te maitai rewa i te pāmahana teitei, kia kore ai e uru ngā poke ki roto i te maitai, kia pā kino ai ki tōna kounga.
