Rauemi Whakamātao Kounga Teitei, He Grits Alumina Whakakotahi Ma me te Tauira Koreutu
Arumina hanumi mā / Kōrunuma māKahaHe rauemi ātete kounga teitei te paura alumina, he mea hanga mai i te paura alumina kounga teitei mā te rewa i runga ake i te 2000 ℃ i roto i te oumu hiko me te whakamatao, ka wehea ki ngā rahi witi rerekē. Ko te alumina ma kua hanumi te rauemi mata matua mō te hanga rauemi ātete kore āhua me te āhua.
He mea hanga te alumina mā kua hanumi ki te paura alumina konutai-iti, he tino parakore, mā te rewa i te pāmahana tiketike, mā te whakamatao kia whakatiotia, kātahi ka kuru. Kei raro i te mana whakahaere pakari te kirikiri alumina mā kua hanumi kia mau tonu te tohatoha rahi o te kōpura me te āhua ōrite.
E whakamahia whānuitia ana i roto i ngā koko whakarewa, ngā rauemi oma rino, ngā rauemi ranunga pū whakapūmau me ētahi atu hua whakapūmau monolithic; Mō ngā rauemi whakapūmau āhua, e whakamahia ana i roto i ngā rauemi mata kounga teitei o te pereki korundum, te korundum mullite, te pereki mono porous maitai whakamahine, te pū rehu whakauru, te hanga maitai me te ahumahi whakarewa tonu.
Ka taea hoki te whakamahi hei rauemi mō te oro, te whakarewa tika, te rehu me te paninga, ngā uku motuhake

Ngā Painga
0-1mm Alumina ma whakakākahu
1. He pakari teitei, he matotoru hoki ngā matūriki. He pai te porowhita o te matūriki kotahi.
2. He mā parakore te tae, kāore he poke, kia mārama ai te tae me te mārama o te pepa ātete-kakahu, te pepa ātete-kakahu rānei.
3. He rite te tohatoha o te rahi matūriki, he ōrite te āhua o te matūriki kotahi, ā, he iti noa te ātete ki te kakahu.
4. He pumau matū, ā, kāore he mahi a te kawakore, he tino pai te pumau o te pāmahana tiketike.
