Para Uku Arumina
Ngā Mōhiohio Hua
Para uku aluminaHe ipu taiwhanga ātete-pāmahana, ātete-waikura hoki tēnei, he mea hanga ki te alumina parakore-teitei (Al₂O₃) hei rauemi mata matua mā roto i tētahi tukanga motuhake. He whānuitia te whakamahinga i roto i ngā taiao whakamātautau pāmahana-teitei i roto i ngā mara o te matū, te whakarewa, me te pūtaiao rauemi.
Ngā Āhuatanga:;
Teitei o te parakore:Ko te parakore o te alumina i roto i ngā ipu uku alumina he teitei ake i te 99%, e whakarite ana i te pumau me te koretake o te matū i ngā pāmahana teitei.
Ātete pāmahana teitei:Ko tōna ira rewa he teitei ki te 2050℃, ka taea e te pāmahana whakamahinga roa te eke ki te 1650℃, ā, ka taea e ia te tu atu i ngā pāmahana teitei tae atu ki te 1800℃ mō te whakamahinga poto.
Ātete ki te waikura:He kaha tōna ātete ki ngā matū waikura pērā i ngā waikawa me ngāngā kawakore, ā, ka taea te pupuri i te mahi pumau i roto i ngā taiao matū kino.
Te kawe wera teitei:Ka taea e ia te kawe me te hora tere i te wera, te whakahaere pai i te pāmahana whakamātautau, me te whakapai ake i te whai huatanga o te whakamātautau.
Te kaha ā-mīhini teitei:He kaha miihini teitei tōna, ā, ka taea e ia te tu atu i te pēhanga nui o waho, me te kore e pakaru wawe.
Te iti o te tauwehenga whānui wera:Ka whakaiti i te mōrearea o te pakaru me te kino i puta mai i te whakawhānui me te whakahekenga wera.
Ngāwari ki te horoi:He maeneene te mata, he ngāwari hoki te horoi me te kore e poke te tauira, kia tika ai ngā hua o te whakamātautau.
