ʻO ka pōhaku Corundum mullite kahi ʻano pōhaku refractory i hana ʻia mai ka maʻemaʻe kiʻekiʻe a i ʻole nā mea maka maʻemaʻe, ʻo ka poloka corundum mullite hoʻi kahi pōhaku ahi alumina kiʻekiʻe i hana ʻia me ka corundum a me ka mullite crystalline phase nui. ʻO ka mea nui o ka pōhaku corundum mullite he corundum plate i lawe ʻia mai, corundum fused maʻemaʻe kiʻekiʻe, e hoʻohana i ka ʻenehana hoʻohuihui pauka superfine holomua, hana ʻia e ka hui ʻana i nā mea, hoʻomaloʻo, hoʻoheheʻe a puhi ʻia i loko o ka umu shuttle wela kiʻekiʻe.
Nā hiʻohiʻona o ka pōhaku Corundum Mullite
- Mea maka kiʻekiʻe kiʻekiʻe,
- ʻO ke corundum maʻemaʻe kiʻekiʻe,
- Paʻa ikaika ka leo ma nā mahana kiʻekiʻe,
- Hoʻoheheʻe ʻia me ke kaomi kiʻekiʻe a me ka mahana kiʻekiʻe,
- Kūleʻa maikaʻi i ka haʻalulu wela,
- Ke kū'ē ʻana i ke komo ʻana,
- Ke kūpale ʻana i ka hoʻouka kaua kemika.
Kaʻina Hana Hana Piliki Corundum Mullite
Hana ʻia ka pōhaku lepo Corundum mullite me nā pōhaku lepo mullite synthetic a loaʻa nā ʻāpana mullite i nā mea hoʻohuihui, a me ka pauka alpha Al2O3 no ka pauka, hiki ke hoʻohui ʻia a hoʻohui ʻia paha nā ʻāpana corundum i nā mea hoʻohuihui, ka pauka mullite synthetic no ka pauka. Hoʻohuihui ʻia ka aggregate a me ka pauka e like me kahi ʻāpana a me ka nui o ka palaoa. Hoʻohana ʻia ka wai ʻōpala o ka pulp pepa me ka sulfite ma ke ʻano he mea hoʻopaʻa, a hoʻohui ʻia nā mea i kahi kauoha. Hoʻohuihui piha ʻia a like, me ka mīkini friction a i ʻole ka mīkini hoʻoheheʻe pōhaku hydraulic. Ma hope o ka maloʻo ʻana o Adobe, puhi ʻia i loko o 1650 ~ 1750 ℃.

Kumukūʻai Brick Corundum Mullite
Ma keʻano laulā, ua māhele ʻia nā pōhaku lepo cordundum mullite i nā pōhaku lepo sintering a me nā pōhaku lepo fused, ʻokoʻa loa ke kumukūʻai o ʻelua ʻano pōhaku lepo refractory corundum mullite ma ka mākeke, aia ke kumukūʻai ma waena o nā tausani a me 10,000. Manaʻo mākou e koho ʻia nā pōhaku lepo corundum mullite like ʻole e like me nā ʻāpana like ʻole o ka umu, ʻaʻole wale e hoʻomaikaʻi i ke ola o ka umu, akā e hoʻemi pū i ke kumukūʻai.
Ka hoʻohana ʻana i ka pōhaku Corundum Mullite no ka umu ahi
Hiki i ka piliki cordundum mullite ke hoʻopili pololei i ka lapalapa, kūpaʻa i ka spalling, kūpaʻa i ka mahana kiʻekiʻe, hiki ke hoʻohana ʻia e like me ka insulation wela o ka uhi umu ʻoihana kiʻekiʻe. Hiki ke hoʻohana ʻia ka piliki ahi corundum mullite e like me nā papa hana umu ʻoihana ʻē aʻe, i hoʻohana nui ʻia i ka ʻoihana petrochemical, ka nui a me ka waena o ka ammonia gasifier a me nā mea magnetic o ka umu kinoea me nā mea, nā mea pono hana umu ʻoihana kiʻekiʻe, a pēlā aku.
