Whakaahuatanga Maka Corundum Mullite
Ko te whakarewa mullite ātete-kore he momo rauemi ātete-kore kaha teitei e hokona ana i te Kamupene RS, ka taea te whakamahi i roto i te oumu sima. Ka taea e ngā whakarewa mullite mūti te whakaatu i ngā āhuatanga teitei pēnei i te kaha kuru teitei, te pumau pāmahana teitei, te ātete ki ngā ru wera, te ātete ki te kakahu me te horo matū i roto i te arai o te kohua teihana hiko nui me ētahi atu taputapu pāmahana teitei. Ka taea te whakamahi i te whakarewa mullite mūti mūti ātete-kore i roto i te oumu maitai, oumu sima, oumu karāhe, oumu hanga rino, oumu kauhanga uku me ētahi atu.
Ngā Āhuatanga o te Corundum Mullite Ka taea te Whakarewa
- Te kaha teitei,
- He ātete kaha ki te kakahu,
- He ātete pai ki te horo,
- He tino pai te pumau o te ru wera,
- Te ātete ki te pāmahana teitei.
Te Tukanga Hanga o te Corundum Mullite Maka
Ko ngā rauemi matua o te whakarewa mullite korunamu he konumohe waikura māmā, he konganuku mullite taiao parakore kounga teitei, me te sima konupūmā aluminate hei hononga. Ka hangaia te whakarewa mullite korunamu ātete mā te tahu i te pāmahana teitei e te oumu ahumahi matatau. Ka piki ake te kaha piko me te kaha pēhi o te mullite korunamu i te tuatahi, kātahi ka heke iho i te pikinga o te pāmahana maimoatanga wera. Ā, ina 5% te ihirangi mana moroiti o te alumina, ka eke te kaha piko ki runga.
Te Hanganga o te Corundum Mullite Maka
Neke atu i te 90% te nui o te Al2O3, ā, ko te whakamātao mullite corundum ka taea te whakarewa me te corundum hei wāhanga tioata matua ka konatunatua ki ngā mea whakamarara tika, ngā mea whakakōkī, me ngā muka maitai kore waikura, ka whakakotahihia kia rite ki te tauira tino pakari. He maha ngā āhuatanga o te mullite corundum ātete-waikura, pērā i te kaha pāmahana teitei, te ātete-mau me te ātete-paru, te kawe wera teitei, te ātete ki te ru wera, te ātete ki te waikura, te hiri pai me te whakatōtō wawe.

Te Whakamahinga o te Corundum Mullite Ka taea te Maka
Ko ngā āhuatanga o te whakarewa ātete mullite korunamu he whānui ōrite, he ātete pai ki te ru wera, he pumau te rōrahi pāmahana teitei, he kaha pāmahana teitei, he ātete teitei i raro i te kawenga, he iti te tere ngoki pāmahana teitei, he kaha kuru teitei, he iti te tere huringa āhua raina, he pakeke teitei, he ātete pai ki te waikura matū, te pakaru me te ātete kakahu. Nā ēnei āhuatanga, he roa te whakamahinga o te whakarewa ātete mullite korunamu, ā, he whānui te whakamahinga i roto i ngā oumu ahumahi rerekē, ngā oumu pāmahana teitei me ētahi atu wāhanga matua o te pāmahana teitei, pēnei i:
- Pūwero, oumu pupuhi, oumu pupuhi wera, oumu whakamahana,
- Orum kauhanga uku, oumu sima, tahu waro,
- Te tatau o te oumu, te whakatuwheratanga o te whāngai, ngā oumu maitai, ngā oumu hanga rino,
- Rūma tahunga, paipa whakarara,
- He poiha nui mō te teihana hiko, he oumu karāhe.
