Ngā pereki ātete-konumohe teiteihe momo rauemi ātete-aluminosilicate me te alumina hei wāhanga matua. Mēnā he nui ake te ihirangi alumina i te 48%, ka whakarōpūtia ēnei hei rauemi ātete-a-kore, he mea hanga mai i te bauxite, i ētahi atu rauemi mata rānei he nui te ihirangi alumina mā te whakahāngai me te whakapūkara.
Whakarōpūtanga:
I runga i te nui o te alumina, ka wehea kia toru ngā momo:
Tau 1: pereki konumohe-teitei (kei roto i te 75% te ihirangi Al₂O₃)
Tau 2: pereki konumohe-teitei (te ihirangi Al₂O₃: 60%~75%)
Tau 3: pereki konumohe-teitei (te ihirangi Al₂O₃: 48%~60%)
Ngā Āhua Pereki Noa me ngā Kōwhiringa Ritenga:
Ngā pereki paerewa, ngā pereki poro, ngā pereki tirotiro, ngā pereki piko, ngā pereki punga, ngā pereki āwhata whānui, ngā pereki waru-ā-toru, ngā pereki whakarewa, me ngā āhua ritenga e ai ki ngā tuhi/tauira a te kiritaki.
Ngā Āhuatanga Ā-tinana me te Matū:
1. Te ātete ki te wera
Ka taea e ia te tu atu i ngā pāmahana teitei i runga ake i te 1770℃, mai i te 1750℃ ki te 1790℃. Ka piki ake te ātete i te pikinga o te ihirangi alumina.
2. Te Pāmahana Whakangawari Utaina
Ko te tikanga he 1420℃~1530℃. Nā te nui o te alumina, te iti o te poke, me te iti o te hanganga o te wāhanga karāhe ka taea te whakarewa, he teitei ake tōna pāmahana whakangawari kawenga i tērā o ngā pereki uku ahi.
3. Kaha Whakapūmau Matao
Ko te kaha pēhi makariri o ngā pereki teitei-alumina o te Tau 1 (LZ-80) he ≥ 70 MPa, ko te kaha pēhi o ngā pereki teitei-alumina o te Tau 3 (LZ-48) he ≥ 40 MPa.
4. Ātete ki te paru
He tata tonu ngā pereki konumohe-nui ki ngā rauemi ātete koretake, e ātete ana ki te mimiti o ngā para waikawa me ngā para kawakore, engari he ngoikore ake tō rātou ātete ki ngā para kawakore i tō ngā para waikawa.
5. Te Āhua o te Porosity
Ko te āhua o te porosity o ngā pereki teitei-alumina o te Taumata 1 he ≤ 21%, ā, ko te porosity o ngā pereki teitei-alumina o te Taumata 3 he ≤ 22%.
