Nā Piliki Mullite Māmā
Hana ʻia mai ka Alumina maikaʻi loa (Al₂O₃) a me Silica (SiO₂), ʻo kā mākouNā Piliki Mullite MāmāLoaʻa i kahi ʻano kristal Mullite paʻa (3Al₂O₃·2SiO₂). Ma ka hoʻohana ʻana i kahi kaʻina hana hoʻohua a me ka hoʻopaʻa ʻana, ua hui pono ʻia nā mea maka, hoʻolei ʻia, hoʻōla ʻia, a puhi ʻia i ka mahana kiʻekiʻe e hana i kahi ʻano insulation porosity kiʻekiʻe. Hōʻoia kēia i ka paʻa wela kiʻekiʻe a me ka pono o ka ikehu no kāu umu.
Nā Hoʻokaʻawale Hoʻohālike Maʻamau
1. Hoʻokaʻawale ʻana e ka nui o ka nui
Nā kumu hoʻohālike e like me JM23-0.6, JM23-0.8, a me JM28-1.0. Hōʻike ka helu hope i ka nui o ka nui (g/cm³), kūpono no nā koi like ʻole o ka halihali ukana a me ka insulation thermal.
2. Hoʻokaʻawale ʻana e ke Kaʻina Hana / Nā ʻAno
ʻO nā laʻana e komo pū ana me nā piliki mullite māmā huʻa (porosity kiʻekiʻe, insulation maikaʻi loa), nā piliki māmā cordierite-mullite (ke kūpaʻa haʻalulu wela koʻikoʻi), a me nā piliki mullite haʻahaʻa hao (Fe₂O₃ ≤ 0.5%, kūpaʻa ikaika i ka pala), e hoʻokō ana i nā kūlana hana kūikawā like ʻole.
Alakaʻi Koho
1. ʻO ka mea mua, koho i ke kumu hoʻohālike kumu e like me ka mahana hana kiʻekiʻe loa o nā lako. No ka laʻana, koho iā JM23 no nā mahana ma lalo o 1300℃, a me JM30 a ʻoi aku paha no nā mahana ma luna o 1500℃.
2. E noʻonoʻo i ka ʻino o ka waena. No nā kūlana ʻino ikaika, koho iā JM28 a ʻoi aku paha, a i ʻole kahi papa hao haʻahaʻa maʻamau.
3. Hoʻohālikelike i nā koi o ka halihali ukana a me ka insulation wela. E koho i nā papa haʻahaʻa no ka hōʻemi kaumaha, a me nā papa kiʻekiʻe no ka ikaika compressive kiʻekiʻe.
