ʻO Corundum mullite brick kahi ʻano brick refractory i hana ʻia mai ka maʻemaʻe kiʻekiʻe a i ʻole nā mea waiwai maʻemaʻe, ʻo ka corundum mullite block he alumina ahi kiʻekiʻe i hana ʻia me ka corundum a me ka mullite main crystalline phase. ʻO ka mea nui o ka corundum mullite brick ka mea i lawe ʻia mai ka pā corundum, kiʻekiʻe maʻemaʻe fused corundum, hoʻohana i ka ʻenehana superfine hoʻohui i ka ʻenehana, hana ʻia e ka mea hui, hoʻomaloʻo, hoʻoheheʻe ʻia a puhi ʻia i ke ahi wela wela.
Nā hiʻohiʻona piliki Corundum Mullite
- kiʻekiʻe kiʻekiʻe waiwai maka,
- ʻO ka corundum maʻemaʻe kiʻekiʻe,
- Paʻa ka leo ikaika i nā wela kiʻekiʻe,
- Hana ʻia me ke kaomi kiʻekiʻe a me ka wela kiʻekiʻe,
- Kūleʻa haʻalulu maikaʻi,
- ʻAʻahu kūʻē,
- Ke kū'ē kū'ē kemika.
Ka Hana Hana Piliki Corundum Mullite
Hana ʻia ʻo Corundum mullite brick me ka synthetic mullite brick a me nā ʻāpana mullite i ka mea aggregate i loaʻa, a ʻo ka pauka alpha Al2O3 no ka pauka, hiki ke hoʻohui ʻia a i ʻole ka sintered corundum particles i ka mea aggregate, synthetic mullite pauda no ka pauka. Hoʻohui ʻia ka aggregate a me ka pauka e like me kahi ʻāpana a me ka nui o ka palaoa. Hoʻohana ʻia ka wai ʻona o ka pulp pepa me ka sulfite e like me ka mea hoʻopaʻa paʻa, a hoʻohui ʻia nā mea i loko o kahi kauoha.Fully hui pū ʻia a hiki, me ka friction press a hydraulic kaomi brick molding machine.Adobe ma hope o ka maloʻo ʻana, puhi i loko o 1650 ~ 1750 ℃.

Kumukuai Brick Corundum Mullite
ʻO ka maʻamau, ua hoʻokaʻawale ʻia nā pōhaku cordundum mullite i ka sintering a me ka fused bricks, ʻokoʻa loa ke kumukūʻai o nā ʻano corundum mullite refractory bricks i ka mākeke, ʻo ke kumukūʻai ma waena o nā tausani a 10,000. Manaʻo mākou e koho ʻia nā pōhaku ahi corundum mullite e like me nā ʻāpana like ʻole o ka kiln, ʻaʻole wale e hoʻomaikaʻi i ke ola o ka umu, akā e hoʻemi hoʻi i ke kumukūʻai.
Hoʻohana ʻia ʻo Corundum Mullite Brick no ka umu ahi
Hiki i ka cordundum mullite brick ke hoʻopili pololei me ka lapalapa, spalling resistance, kiʻekiʻe wela kūpaʻa, hiki ke hoʻohana ʻia e like me ka insulation wela o ke kiʻekiʻe wela o ka umu ahi. Hiki ke hoʻohana ʻia ka corundum mullite fire brick e like me nā papa hana umu ahi ʻē aʻe, i hoʻohana nui ʻia i ka ʻoihana petrochemical, nui a me ka nui o ka ammonia gasifier a me nā mea magnetic o ka umu ahi me nā mea, kiʻekiʻe kiʻekiʻe kiʻekiʻe ʻoihana kiln mea pono, etc.
