Ngā Pereki Arai Arumina
Ngā pereki arai konumohehe mea hanga mai i ngā rauemi mata alumina kounga teitei mā te whakataurite i ngā ōwehenga, te pēhi pēhanga teitei me te tahu pāmahana teitei. He nui te ihirangi Al₂O₃, he hanganga ōrite me te mahi pumau, e whakamahia whānuitia ana hei rauemi whakapuru i roto i ngā taiao ahumahi pāmahana teitei, kakahu teitei me te waikura.
He tino pai te tiaki a ā mātou pereki arai alumina mō ngā oumu ahumahi, ngā oumu, ngā paipa, ngā awhiowhio, ngā awaawa me ngā taputapu tauhohenga, ā, ka whakaitihia te kakahu, te waikura me te ngaronga wera, ā, ka whakapai ake i te roa o te ora o ngā taputapu me te whai huatanga o te whakaputanga.
Ka tautoko mātou i ngā ine ritenga, ngā āhua motuhake me ngā momo alumina rerekē hei whakatutuki i ngā whakaritenga motuhake o tō kaupapa.
Ngā Painga Matua:
1. Ātete ki te pāmahana teitei
Ka taea te tu atu i te pāmahana mahi mō te wā roa tae atu ki te 1350°C–1750°C, i runga i te momo.
2. Ātete Tino Kaha ki te Mau
He pakari teitei, he iti te tere o te pakū, ā, he pai te ātete ki te horoi me te waku o ngā rauemi.
3. Ātete Kaha ki te Waikura
He ātete pai ki te waikawa, te kawakore, te para rewa, te puehu me te waikura matū.
4. Te Pūmautanga Wera Pai
He iti te tere whakawhanui wera, he kaha te ātete ki ngā ru wera, he iti ake te pakaru.
5. Te roa o te ora ratonga
Whakaitihia te auau o ngā mahi tiaki, te wā kore mahi, me te utu whakahaere whānui.
6. Tāutanga Māmā
Kei te wātea ngā rahi paerewa me ngā rahi ritenga mō te hanganga me te whakakapinga watea.
