Ngā Pereki Rino Rere
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.
