He momo rauemi ātete-ātete te pereki ahi silica alumina, he āhuatanga ātete-ātete teitei te pereki ātete-ātete silica alumina, he ātete-ki-te-horo me te kaha teitei. He maha ngā momo pereki ahi o te pereki ātete-ātete silica konumohe pērā i te pereki silica, te pereki uku ahi, te pereki alumina teitei, te pereki mullite me te pereki korundum. Ka taea te whakamahi i te pereki ahi silica alumina mō ngā momo taputapu wera katoa.
Te Whakarōpūtanga o te Pereki Ahi Silica Alumina
E ai ki te raupapa o te pikinga o te ihirangi mai i te SiO2 ki te Al2O3, ka whakarōpūtia ngā pereki ahi konumohe silicon ki ngā kāwai e whai ake nei:
Pereki silica: he nui ake te ihirangi o te SiO2 i te 93%,
Pereki uku: ko te ihirangi o te Al2O3 he 30%-48%,
Pereki alumina teitei: he nui ake te ihirangi o te Al2O3 i te 48%,
Pereki Mullite: ko te ihirangi o te Al2O3 he nui ake i te 72%, ā, ko te ihirangi o te SiO2 he nui ake i te 28%,
Pereki korunuma: neke atu i te 90% te ihirangi Al2O3.
Te Whakamahinga o te Pereki Ahi Silica Alumina
Ko te pereki silica e whakamahia nuitia ana mō te hanga oumu kōka, oumu karāhe, oumu uku, oumu whakawera waro, ā, kāore e pai mō ngā taputapu whakamahana e piki haere ana te pāmahana i raro i te 600 ℃.
Ka whakamahia tonutia te pereki uku i roto i ngā oumu pupuhi, i ngā oumu wera pupuhi, i ngā oumu whakamahana, i ngā kohua hiko, i ngā oumu raima, i ngā oumu hurihuri, i ngā oumu uku me ngā oumu whakawera.
Ko te pereki alumina teitei te mea e whakamahia nuitia ana i roto i te hanga maitai, i te umanga konganuku kore-ferrous me ētahi atu ahumahi.
E whakamahia ana te pereki mullite i roto i ngā momo ahumahi katoa, tae atu ki te whakarārangi mata wera me te whakarārangi tuara o te oumu, i roto i te ahumahi whakarewa, te ahumahi hinu matū, te ahumahi rauemi hanga, te ahumahi uku, me te ahumahi mīhini.
Ka taea te whakamahi i te pereki korunuma i roto i te oumu pupuhi, te oumu wera pupuhi, te oumu karāhe me ētahi atu.
Ngā Āhuatanga o te Pereki Ahi Silica Alumina
- Te ātete nui,
- He ātete pai ki te ru wera,
- Te ātete kaha ki te horo waikawa,
- Te kaha o te pāmahana teitei,
- Te tauwehenga whakawhanui wera iti,
- Te kawe wera teitei.
