Pereki Mullite me ngā Pereki Sillimanite
Ngā Mōhiohio Hua
Pereki MulliteHe whare konumohe teitei te ātete, ko te mullite te wāhanga tioata matua. Ko te tikanga, ko te ihirangi o te alumina kei waenga i te 65% me te 75%. Haunga te mullite, ko ngā kohuke he iti te ihirangi alumina kei roto hoki he iti te wāhanga vitreous me te cristobalite. Ko te ihirangi alumina teitei ake kei roto hoki he iti te corundum. Ko te nuinga o te wā ka whakamahia mō te oumu wera wera, te tinana me te raro o te oumu wera, te kaiwhakahou oumu karāhe, te oumu uku, te arai kokonga mate o te pūnaha pakaru hinu, me ētahi atu.
Whakarōpūtanga:Mullite Iti e Toru/Multite Kua Whakatōkia/Multite Kua Whakakotahitia/Multite Sillimanite
Ngā pereki SillimaniteHe pereki ātete-waikura ngā pereki, he pai ngā āhuatanga, he mea hanga mai i ngā kohuke sillimanite mā te whakamahana pāmahana teitei, mā te whakarewanga paru rānei. Ka hurihia te Sillimanite hei mullite me te silica kore utu i muri i te whakamahana pāmahana teitei. I te nuinga o te wā ka hangaia mā te whakamahana pāmahana teitei me te whakarewanga paru.
Ngā Āhuatanga:He pai te pumau o te pāmahana i te pāmahana tiketike, he ātete ki te horo o te wai karāhe, he iti te parahanga ki te wai karāhe, ā, he pai te nuinga mō te hongere whāngai, te mīhini whāngai, te mīhini kukume ngongo me ētahi atu taputapu i roto i te umanga karāhe, ka taea ai te whakapai ake i te hua.
Ngā Hua:Pereki awaawa, waka rere, paipa hurihuri, peihana whāngai, mowhiti kōhao, hoe whakaoho, poka, rango whāngai, pereki para poraka ahi, poraka whakakā, pereki āwhata, taupoki peihana whāngai, pereki puta-kōhao, pereki mura, kurupae, pereki uhi me ētahi atu momo me ngā whakaritenga.

Tono
Pereki Mullite:
Ahumahi uku:Whakamahia mō ngā whata oumu, ngā pana, ngā pakitara oumu, me ngā pereki tahu i roto i ngā oumu uku, kia mau tonu ai ngā pāmahana i runga ake i te 1600℃ me ngā huringa pāmahana maha, kia whakaitihia ai te kakahu o te oumu, kia pai ai hoki te tahu i te hua.
Ahumahi Whakarewa:He pai mō te whakarārangi i ngā oumu wera i roto i ngā wheketere maitai me ngā oumu i roto i te whakarewa konganuku kore-ferrous, ātete ana ki te horo o te konganuku rewa me te para, me te pumau hanganga pai i te pāmahana teitei.
Ahumahi Karāhe:Whakamahia hei pereki whakarara mō ngā pakitara taha, raro, me ngā awa rere o ngā oumu karāhe, kia mau tonu ai te horoinga o te karāhe rewa me te waikura pāmahana teitei, kia roa ake ai te ora o te oumu, kia mau tonu ai te hanga karāhe.
Ētahi atu Whakamahinga mō te Pāmahana-Teitei:Whakamahia mō te whakarārangi i ngā tahunga para, ngā kohua ahumahi, me ngā taputapu whakamātautau pāmahana-tiketike i roto i ngā ahumahi rererangi me te hikohiko, kia urutau ai ki ngā taiao pāmahana-tiketike uaua, kino hoki.
Ngā Pereki Silimanite:
Te Ahumahi Rino me te Maitai:Whakamahia hei pereki tirotiro i roto i ngā oumu wera pupuhi, hei whakapuru hoki mō ngā paipa pupuhi wera, ka taea te tu atu i ngā pāmahana neke atu i te 1300℃ me te mimiti o te hau, ka roa ake te ora o ngā taputapu.
