Pereki Mullite Māmā Raupapa JM mō te Umu Waka, JM23 JM26 Ārai Ātete mō te Ahumahi Uku
Kei a mātou ngā taputapu whakaputa hou rawa atu, ngā miihini me ngā kaimahi whai wheako me te tohu, ngā pūnaha whakahaere kounga teitei e mōhiotia ana, me te tautoko kaimahi ngaio hoki i mua/i muri i te hoko.Pereki Mullite Māmā, Kei roto i tā mātou wheketere kei Haina ēnei otinga katoa. Nō reira, ka taea e mātou te whakamana i tō mātou kounga me te tino wātea. I roto i ēnei tau e whā, ehara i te mea ko ā mātou taonga anake ka hokona e mātou engari ko ā mātou ratonga hoki ki ngā kiritaki puta noa i te ao.
I hangaia mai i te Alumina kounga teitei (Al₂O₃) me te Silica (SiO₂), ā mātouPereki Mullite MāmāHe hanganga tioata Mullite (3Al₂O₃·2SiO₂) pumau. Mā te whakamahi i tētahi tukanga whakapūmau me te whakapūmau matatau, ka whakaranua tika ngā rauemi mata, ka whakarewaina, ka whakamaroketia, ka tahuna ki te pāmahana teitei hei hanga i tētahi hanganga whakamarumaru ōrite, he nui te porowhita. Mā tēnei ka whakarite i te pumau wera me te whai huatanga pūngao mō tō oumu.
Ngā Whakarōpūtanga Tauira Noa
1. Whakarōpūtanga mā te Kiato Papatipu
Ngā tauira pēnei i a JM23-0.6, JM23-0.8, me JM28-1.0. Ko te tau tāpiri e tohu ana i te kiato papatipu (g/cm³), e tika ana mō ngā whakaritenga rerekē mō te kawe kawenga me te whakamahana.
2. Whakarōpūtanga mā te Tukanga/Ngā Āhuatanga Whakaputa
Ko ētahi tauira ko ngā pereki mullite māmā pahuka (he nui te porowhita, he pai te whakamarumaru), ngā pereki māmā cordierite-mullite (he tino ātete ki ngā ru wera), me ngā pereki mullite iti-rino (Fe₂O₃ ≤ 0.5%, he kaha te ātete ki te waikura), e tutuki ana i ngā tikanga mahi motuhake.
Aratohu Kōwhiringa
1. Tuatahi, tīpakohia te tauira taketake e ai ki te pāmahana whakahaere mōrahi o te taputapu. Hei tauira, tīpakohia te JM23 mō ngā pāmahana i raro i te 1300℃, me te JM30, neke atu rānei mō ngā pāmahana i runga ake i te 1500℃.
2. Whakaarohia te kaha o te waikura o te rauemi. Mō ngā āhuatanga kaha o te waikura, tīpakohia te JM28, teitei ake rānei, he iti rānei te rino kua whakaritea.
3. Whakatauritehia ngā whakaritenga whakamarumaru o te kawenga me te wera. Kōwhiria ngā momo iti-kiato hei whakaiti i te taumaha, me ngā momo teitei-kiato hei whakanui ake i te kaha pēhi.
Ngā Āhuatanga:
Te ātete nui:Ko te kaha ātete ki te wera i te nuinga o te wā neke atu i te 1600°C, e mau tonu ana ngā āhuatanga ā-tinana me te matū i roto i ngā taiao pāmahana teitei.
Te kawe wera iti:Nā te mama o tōna hanganga, he iti tōna kawe wera, ko te tikanga he 0.1-0.2 W/(m·K), ā, he pai te whakaiti i te ngaronga wera me te whakapai ake i te whai huatanga o te pūngao wera.
Te kaha teitei, te mātotoru iti:Ko te mātotoru papatipu kei waenga i te 0.5-1.3 g/cm³, e whakaiti ana i te taumaha hanganga me te pupuri tonu i te kaha teitei.
He ātete pai ki te ru wera:Ka ātete ki ngā piki me ngā heke tere o te pāmahana, ka ātete ki te pakaru i te wā e tīmata ana, e whakaweto ana hoki te oumu, ā, ka mau tonu te pumau o te hanganga.
Ātete matū:He ātete tino pai ki ngā para me ngā hau waikawa me ngā hau kawakore, e āhei ai te whakamahi mō te wā roa i roto i ngā taiao waikura.
Iti te ihirangi poke:Ka whakamahia ngā rauemi mata parakore-teitei i roto i te tukanga whakaputa, ka hua ake he iti te ihirangi poke, ka whakaiti i te parahanga o te hua i roto i ngā taiao pāmahana teitei.
