Whakaahuatanga o te Pereki Whakamarumaru Uku Mama
Ko te pereki whakamarumaru uku māmā he mea hanga ki te paru ahi hei rauemi mata me te uku kirihou hei mea here, kātahi ka tāpirihia he mea mura, he mea pahuka rānei e tika ana mā te tahu. Ko te ārai paru he teitei te āhua o te poresity, tata ki te 40~85%, ā, he iti iho i te 1.5 karamu/cm3 te matotoru. Ko ngā pereki whakamarumaru uku te nuinga o te wā e whakamahia ana hei rauemi whakamarumaru i roto i ngā oumu ahumahi hei whakaiti i te ngaronga wera o te oumu, hei penapena pūngao, hei whakaiti hoki i te kounga o ngā taputapu wera.
Ngā Āhuatanga o te Pereki Whakamarumaru Uku Mama
- He iti ngā taumata o te rino me ētahi atu poke,
- Te ātete nui,
- He nui te porosity, he iti te mātotoru rōrahi,
- He pai te pānga ārai wera me te penapena pūngao,
- He pai te pumau o te ru wera,
- Te ātete ki te waikura me te horo.
Te Tukanga Hanga o te Pereki Whakamarumaru Uku Mama
Ko ngā pereki whakamarumaru uku māmā he mea hanga mai i te uku ahi me te mea here tino parakore, mā te whakawera i roto i te pāmahana teitei. Ko ngā poraka whakamarumaru uku he pereki whakamarumaru ātete utu iti me te mahi teitei. Ko ngā painga matua o te poraka whakamarumaru uku ko te ātete teitei i raro i te kawenga, te iti o ngā tauwehenga whānui raina, te ātete pai ki ngā ru wera me te kaha ki te ātete ki te horo. He mea hanga mai i ngā rauemi uku ahi kounga teitei o te rohe i raro i te pāmahana teitei e ai ki te paerewa ā-motu e mau tonu ana, he rite te matotoru, he kaha teitei, he iti te kawe wera me te iti o te poke.
Te Hanganga o te Pereki Whakamarumaru Uku Mama
He hua papaka te pereki uku whakamātao, kei roto i te 30~40% te Al2O3. He mea hanga tēnei mai i te 50% uku ngohengohe me te 50% chamotte mārō, kia rite ki te matotoru, me whakaranu, ā, me tahu ki te pāmahana teitei o te 1300~1400 ℃ i muri i te whakahāngai me te whakamaroke. Ko te hanganga matua o te pereki uku whakamātao ko te kaolinite (Al2O3·2SiO2·2H2O) me te 6~7% poke (K, Na, Ca, Ti, Fe oxide).
