White Corundum Grit White Fused Alumina Me Te Kounga Teitei
AKORANUMA WHAKAKĀHUI MĀ
Ko te alumina whatu mā (WFA) he rauemi mata mō te hanga rauemi ātete-waikura. E kiia ana hoki ko te korundum mā, ko te waikura konumohe mā rānei. Ki te whakataurite ki te alumina whatu parauri, he ōrite ake te hanganga matū, te hanganga me ngā āhuatanga. Ko te hua he hua pakari teitei, he ngawari ki te pakarukaru, he parakore teitei, he teitei te ira rewa, me te rahi tioata nui. He whānui te whakamahinga i roto i te umanga ātete-waikura, ka taea hoki te whakamahi i roto i ngā wira huri āhua uku, te pepa kirikiri, ngā mea pupuhi, te whakarite konganuku, te paninga laminates, te whakakoi, te whakakoi, te huri me te rau atu o ngā tono.

NGĀ ĀHUATANGA ALUMINA WHAKAKĀHUI MĀ
He mea hanga te alumina ma kua hanumihia (WFA) mai i te paura waikura konumohe kounga teitei/ paura alumina he ira rewa neke atu i te 2200°C. Ahauhe tino pakeke, he ngawari ki te pakarukaru, he tino parakore. Nā te pumau pai o te wera o te alumina White whētui, ka taea te whakamahi mō ngā rauemi ātete matau, ngā mea whakarewa ātete me ētahi atu rauemi ātete.
NGĀ PAINGA O TE ALUMINA WHAKAKĀHUI MĀ
1. Te horoi i ngā mata whakarewa me te tango i te rauemi (te pānga whakakoi)
2. Te tango i te waikura me te unahi mai i ngā mata whakarewa
3. Te tango i te tae whakamahana
NGĀ TONO ALUMINA WHAKAKĀHUI MĀ
He momo parakore rawa te konumohe waikura mā, he pai mō te whakamahi me te kowiri tira me te konumohe. He koki, he pakarukaru, he mārō hoki tēnei mea whakarewa kore-rino ka taea te whakamahi anō. He kaha tōna pānga ki te mata e whakarewaina ana. Kei roto te konumohe whakarewa mā i te rōpū konumohe whakarewa.
1. Te pupuhi onepu, te whakakanapa me te huri i te konganuku me te karāhe.
2. Te whakakī i te peita, te paninga ātete-kakahu, te uku, me te paninga kanapa.
3. Te hanga i te kōhatu hinu, te kōhatu huri, te wira huri, te pepa kirikiri me te kakahu emery.
4. Te hanga i ngā kiriuhi tātari uku, ngā ngongo uku, ngā pereti uku.
5. Te whakaputanga o te wai whakakanapa, te ware pi totoka me te ware pi wai.
6. Mō te whakamahi i te papa ātete-kakahu.
7. Te huri me te whakakanapa matatau o ngā tioata piezoelectric, ngā semiconductors, te maitai kore waikura, te konumohe me ētahi atu konganuku me ngā mea kore-konganuku.
8. Ngā Whakatakotoranga me te Hanganga
