Ngā pereki mullite JM23, JM26, me JM28He rauemi whakamahana werawera māmā, mahi teitei, e whakamahia whānuitia ana i roto i ngā taputapu pāmahana teitei ahumahi. E kapi ana i ngā awhe ātete pāmahana rerekē, ka mahi ēnei momo paerewa e toru hei otinga whakapuru wera pai mō ngā oumu, ngā oumu ahumahi, ngā poiha me ngā pūnaha maimoatanga wera. He iti te kawe werawera, he mama, he ātete ru werawera pai rawa atu, me te mahi pāmahana teitei pumau, e mōhiotia whānuitia ana ngā pereki mullite raupapa JM puta noa i te ao hei rauemi werawera kounga teitei hei whakaiti i te whakapaunga pūngao me te whakaroa i te roa o te ratonga oumu.
Kua hangaia ia karaehe JM mō ngā pāmahana mahi motuhake kia uru ki ngā āhuatanga ahumahi rerekē. Ka mahi pūmau ngā pereki mullite JM23 i ngā pāmahana tae atu ki te 1260°C. Nā te mātotoru tino māmā me te whakamarumaru wera pai rawa atu, e whakamahia whānuitia ana mō te whakapuru me ngā paparanga whakamarumaru o ngā oumu pāmahana-waenga me te pāmahana-iti, e whakaiti ana i te ngaronga wera, e whakapoto ana i ngā huringa whakamahana me te whakapai ake i te whai huatanga o te pūngao whānui.
Ka tautokohia e ngā pereki mullite JM26 te mahi tonu i te 1430°C, ka tutuki he taurite pai i waenga i te whakamarumaru wera me te kaha miihini. Ātete ki ngā piki me ngā heke o te pāmahana me te pakaru o te hanganga, he whānuitia te whakamahinga o tēnei momo mahi i roto i ngā oumu kauhanga uku, ngā oumu whakamahana ahumahi me ngā taputapu whakamahana hinu-matū. Koinei te whiringa tino whai hua mō te nuinga o ngā kaupapa whakamarumaru pāmahana waenga-ki-teitei.
I hangaia mō ngā āhuatanga mahi tino kino tae atu ki te 1540°C, ko ngā pereki mullite JM28 te otinga pāmahana teitei rawa atu. Nā te nui o te alumina me te kaha ātete pai, ka tukuna e rātou he pumau pāmahana teitei, he ātete ki te horo para me te pakari hanganga, he mea tino pai mō ngā oumu uku pāmahana teitei, ngā kaiwhakaora oumu karāhe me ngā arai oumu whakarewa.
He painga matua ngā pereki whakamahana mullite JM23, JM26 me JM28 katoa, tae atu ki te iti o te rokiroki wera, te iti o te horapa wera, te ātete pai ki te kawakore me te kaha ārai-waikura. Ki te whakatauritea ki ngā pereki taumaha ātete-waikura tuku iho, ka tino whakaitihia te kawenga oumu, ka tapahia ngā utu pūngao whakahaere me te iti ake o te auau tiaki taputapu.
Ka tukuna e mātou ngā pereki mullite raupapa JM paerewa me ngā rahi ritenga me te tirotiro kounga tino pakari, te mahi puranga ōrite me te utu wheketere whakataetae. Kei te wātea he aratohu whiriwhiri tohu ngaio i runga i te pāmahana o tō oumu, te taiao mahi me ngā tono kaupapa.
Mena kei te rapu koe i ngā pereki mullite pono mō te hanganga oumu hou, mō te whakakapinga rānei i ngā arai ātete ahi, tēnā tukua mai he pātai. Ka whakaratohia e mātou he pepa raraunga hangarau kore utu, he whakatau utu tika me ngā otinga whakahaere kua whakaritea i roto i ngā haora 24.
