1. He aha te kirikiri uku?
Ko te nuinga o te onepu uku he mea hanga mai i nga kohuke kei roto Al2O3 me SiO2 me te taapiri me etahi atu rauemi kohuke. He kirikiri hanga porowhita i mahia e te paura, te pelletizing, te sintering me te mahinga māka. Ko tona hanganga tioata matua ko Mullite me Corundum, he porotaka te ahua o te witi, te kaha o te whakamaarama, te pai o te whakamaarama matū, te iti o te whakawhänuitanga o te waiariki, te paheketanga me te aukati ， nga ahuatanga o te wehenga kaha. Ka taea te whakamahi i te kirikiri kirikiri ki te whakaputa i nga whakarewanga o te kounga teitei e nga momo mahi makanga kirikiri.
2. Te waahi tono o te onepu uku
Ko te kirikiri kirikiri kua tino whakamahia i roto i nga hangahanga o te nuinga o nga momo hangarau hangahanga, penei i te kirikiri whakakikoruatia te kapia, te tukanga whakamaroke-whaiaro (F NB, APNB me te Pep-set), pouaka makariri, pouaka wera, kirikiri ta 3D, me te tukanga pahuka i ngaro. .
3. Te whakatakotoranga o te kirikiri kirikiri
Ka taea e SND te whakarato kirikiri kirikiri o nga momo whakaritenga. Mo te hanganga matū, he nui te konumohe-waikura, te kirikiri konumohe-waikura reo me te kirikiri konumohe-waikura iti, e whakamahi ana ki nga momo whakarewanga rereke. He tohatoha rahi matūriki katoa ki te whakatutuki i nga hiahia a nga kaihoko.
