Ka hoʻokaʻawale ʻana o nā piliki ahi insulation māmā no nā umu aniani 2

Ma kēia pukana e hoʻomau mākou i ka hoʻolauna ʻana i ka hoʻokaʻawale ʻana o nā piliki ahi insulation māmā no nā umu aniani.

3. Lepo lepopiliki ahi hoʻomehana māmāHe huahana pale pale ia i hana ʻia mai ka pālolo pale me ka nui o Al2O3 he 30% ~ 48%. Hoʻohana kāna hana hana i ke ʻano hoʻohui puhi a me ke ʻano huʻa. Loaʻa i nā piliki ahi pale māmā ka pālolo i nā noi he nui, hoʻohana nui ʻia ma ke ʻano he mau mea pale pale o nā papa pale i nā umu ʻoihana like ʻole kahi i pili ʻole ai me nā mea i hoʻoheheʻe ʻia. ʻO kona mahana hana he 1200 ~ 1400 ℃.
4. Nā piliki hoʻopaʻa ʻokikene alumini. Loaʻa i ka huahana ke kūpaʻa ahi kiʻekiʻe a me ke kūpaʻa haʻalulu wela maikaʻi, a hoʻohana pinepine ʻia ma ke ʻano he papa hoʻopaʻa wela kiʻekiʻe no nā umu. ʻO kona mahana hana he 1350-1500 ℃, a hiki i ka mahana hana o nā huahana maʻemaʻe kiʻekiʻe ke hiki i 1650-1800 ℃. He mau huahana hoʻopaʻa refractory ia i hana ʻia mai nā mea maka o ka corundum fused, alumina sintered, a me ka alumina ʻoihana.
5. Nā piliki mullite māmā. ʻO nā huahana insulation wela a me nā huahana refractory i hana ʻia mai ka mullite ma ke ʻano he mea maka nui. Loaʻa i nā piliki mullite ke kūpaʻa wela kiʻekiʻe, ka ikaika kiʻekiʻe, ka conductivity thermal haʻahaʻa, a hiki ke hoʻopili pololei ʻia me nā lapalapa, a kūpono lākou no ka uhi ʻana o nā umu ʻoihana like ʻole.
6. Nā pōhaku lepo poepoe hakahaka alumini oxide. Hoʻohana nui ʻia nā pōhaku lepo poepoe hakahaka alumini oxide no ka hoʻohana lōʻihi ma lalo o 1800 ℃. Loaʻa iā ia ke kūpaʻa kemika maikaʻi a me ke kūpaʻa i ka palaho i nā mahana kiʻekiʻe. Ke hoʻohālikelike ʻia me nā pōhaku lepo māmā ʻē aʻe, ʻoi aku ka mahana hana o nā pōhaku lepo poepoe hakahaka alumina, ʻoi aku ka ikaika, a me ka conductivity thermal haʻahaʻa. ʻO kona density he 50% ~ 60% haʻahaʻa ma mua o nā huahana refractory paʻa o ka haku mele like, a hiki ke kū i ka hopena o nā lapalapa wela kiʻekiʻe.
