Ngongo Ukume Alumina Porowhita
Ngā Mōhiohio Hua
Ngā ngongo konumoheka wehea te nuinga ki ngā ngongo korundum, ngā ngongo uku me ngā ngongo konumohe teitei, he rerekē te hanganga, ngā āhuatanga me ngā whakamahinga.
Ngongo kōrunuma:Ko te rauemi mata o te ngongo korunduma ko te alumina, ā, ko te wāhanga matua ko te α-alumina (Al₂O₃). He nui te pakeke o te ngongo korunduma, ko te pakeke o Rockwell ko HRA80-90, ā, he tino pai te ātete ki te kakahu, he rite ki te 266 ngā wā o te maitai manganese me te 171.5 ngā wā o te rino maka chromium teitei. Hei tāpiri, ko ngā āhuatanga o te ngongo korunduma ko te ātete ki te taka, te matotoru teitei me te pumau matū pai. He maha te whakamahinga i roto i ngā wāhanga ātete-kakahu, ngā peera uku, ngā hiri, me ētahi atu. Hei tāpiri, ka whakamahia hoki ngā ngongo korunduma mō ngā rauemi peera o ngā wati me ngā mīhini tika.
;
Ngongo uku:Ko te hanganga o ngā ngongo uku he alumina tino parakore (pērā i te porcelain 99) he alumina noa rānei (pērā i te porcelain 95, te porcelain 90, me ētahi atu). Ko ngā uku alumina tino parakore (pērā i te porcelain 99) he nui ake te ihirangi Al₂O₃ i te 99.9%, ā, ko te pāmahana whakawera tae atu ki te 1650-1990℃. He tino pai te whakawhiti mārama me te ātete ki te waikura konganuku kawakore. He maha ngā wā ka whakamahia ngā ngongo uku alumina tino parakore i roto i ngā rama konutai me ngā papa hikohiko whakauru me ngā rauemi whakamahana auau-teitei i roto i te umanga hikohiko nā te mea he pai ake te whakawhiti mārama me te ātete ki te waikura. Ka whakamahia ngā ngongo uku alumina noa mō ngā oko wera-teitei, ngā ngongo oumu ātete-wera me ngā rauemi ātete-kakahu motuhake.
Ngongo konumohe-teitei:Ko te wāhanga matua o ngā ngongo konumohe-teitei ko te konumohe, engari ko te nuinga o te wā kei waenganui i te 48%-82%. E mōhiotia ana ngā ngongo konumohe-teitei mō tō rātou ātete pai ki te pāmahana teitei me te kaha teitei. He whānuitia te whakamahinga i roto i ngā mara pēnei i ngā ngongo tiaki thermocouple me ngā anga oumu ngongo. Ka taea e rātou te tiaki pai i ngā wāhanga o roto mai i te kino o te pāmahana teitei, me te whakaroa i tō rātou roa mahi.
