Whakaahuatanga o te Pereki Mirumiru Alumina
Ko te pereki mirumiru arumina he momo rauemi whakamahana pāmahana teitei hou, he mea hanga ki te alumina ahumahi i roto i te oumu hiko mā te whakarewa me te pupuhi. Ko te āhua o te pereki mirumiru arumiru arumiru he tioata moroiti a-Al2O3, ā, ko te tinana matua he mirumiru alumina ka taea te hanga hei momo hua katoa me ngā āhua rerekē hei mahi i te pāmahana teitei rawa atu o te 1800℃ me te kaha miihini teitei me te iti o te matotoru.
Ngā Āhuatanga o te Pereki Mirumiru Alumina
- Mama te taumaha,
- Te penapena pūngao,
- Te utu hanga iti iho,
- Te ātete ki te pāmahana teitei,
- Te iti o te huringa raina whakamahana anō,
- He ātete pai ki ngā ru wera.
Te Tukanga Hanga o te Pereki Mirumiru Alumina
Ko te pereki ahi mirumiru konumohe e whakamahi ana i te pōro mirumiru konumohe hei rauemi mata matua, ko te paura tino pai te mahi hei āpiti me te matū waro hei āpiti here mā te hanga me te whakamaroke, kātahi ka tahuna ki roto i te oumu tere pāmahana teitei.
Painga o te Pereki Mirumiru Alumina
He āhuatanga ātete wera me te iti o te kawe wera o te pereki ahi mirumiru konumohe, ka hua ake he pānga ātete wera nui, ka whakaiti i te moumou wera me te whakapai ake i te pai o te wera. Mā te whakamahi i te pereki ātete mirumiru konumohe ka taea te penapena pūngao tae atu ki te 30%. Ā, he teitei te pāmahana ratonga o te poraka mirumiru konumohe tae atu ki te 1750 ℃. He pai te pumau o te wera me te iti o te tere huringa raina whakamahana anō, ka roa te ora ratonga o te poraka mirumiru konumohe.
