He tino pai te kounga o ngā pōro ātete alumina, arā, he kaha teitei, he pakeke teitei, he kaha ki te pakū, he matotoru te matotoru, he kaha ki te pāmahana teitei, he ātete ki te waikura, he iti ake te parahanga me ētahi atu āhuatanga pai. Kua whānuitia te whakamahinga o ngā pōro alumina mō te whakaoti me te tukatuka hohonu i ngā momo uku, enamel, karāhe, matū me ētahi atu rauemi matotoru me te mārō.
Ngā Āhuatanga o ngā Pōro Ātete Alumina
- Ātete ki te pāmahana teitei
- Ātete Wera Pai
- Te Kaha Mīhini Teitei
- Te Ora Ratonga Roa
Te Hanganga o ngā Pōro Ātete Alumina
He mea hanga ngā pōro ātete alumina ki te AL2O3, te kaolin, te konganuku hangai, te karaihe mullite me ētahi atu rauemi. E ai ki te tikanga hurihuri me te tikanga pēhi, he kaha teitei, he ātete pai ki ngā ru wera, he watea te whakakapinga me te horoi, he roa te ora mahi, me ētahi atu.
Tukanga Pōro Ātete Alumina
Hei hanga pōro ātete-alumina, ka whakatakotoria te hikohiko ki raro i te oko karāpiti, ā, ka taea te tīmata i te pewa mā te tāpiri i tētahi nui o te paura alumina ahumahi. Ko te iahiko whakahaere he 1.0kA, ko te ngaohiko he 80~100V. Whai muri i te patu, ka rewa te Al2O3, ka utaina mārire, kia kī tonu te wai o te rauemi i te oko karāpiti, ko te pāmahana wai o te rauemi he 2200 ~ 2300 ℃. Whai muri i tēnā, ka ringihia te oko karāpiti, ā, ka rere te otinga ki waho.

Te Whakamahinga o ngā Pōro Ātete Alumina
Kua whānuitia te whakamahinga o ngā pōro ātete-konumohe mō te whakaoti me te tukatuka hōhonu i ngā momo uku, enamel, karāhe, matū me ētahi atu rauemi matotoru me te mārō. Ina koa ko ngā pōro ātete-konumohe e tika ana mō ngā taputapu wehewehe hau, me te oumu hau hau rino hei whakakī rokiroki wera.
