ʻO ka hoʻokaʻawale ʻana i nā pōhaku lepo ahi no nā kiln aniani 2

ʻO kēia pukana e hoʻomau mākou i ka hoʻolauna ʻana i ka hoʻokaʻawale ʻana o nā pōhaku ahi insulation māmā no nā kiln aniani.

3.Palolopōhaku ahi hoʻomāmā māmā. ʻO ia kahi huahana refractory insulation i hana ʻia mai ka pālolo refractory me Al2O3 maʻiʻo o 30% ~ 48%. Hoʻohana ke kaʻina hana i ke ʻano hoʻohui ahi a me ke ʻano foam. Loaʻa i nā pōhaku lepo ahi ka māmā o ka pālolo, i hoʻohana nui ʻia e like me ka insulation refractory mea o nā papa insulation i nā kiln ʻoihana like ʻole kahi i hui ʻole ʻia me nā mea hoʻoheheʻe. ʻO kona mahana hana he 1200 ~ 1400 ℃.
4. Aluminum oxide insulation bricks. He kiʻekiʻe ke ahi kūʻokoʻa ka huahana a me ke kūpaʻa haʻalulu wela maikaʻi, a hoʻohana mau ʻia e like me kahi papa hoʻonā wela kiʻekiʻe no nā kiln. ʻO kona mahana hana he 1350-1500 ℃, a hiki i ka mahana hana o nā huahana maʻemaʻe kiʻekiʻe ke hiki i 1650-1800 ℃. ʻO ia nā huahana insulation refractory i hana ʻia mai nā mea maka o ka corundum fused, alumina sintered, a me ka alumina ʻoihana.
5. Nā pōhaku lepo mullite māmā. ʻO ka insulation thermal a me nā huahana refractory i hana ʻia mai ka mullite ma ke ʻano he kumu kumu. Mullite insulation bricks he kiʻekiʻe ka pale wela, ka ikaika kiʻekiʻe, ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, a hiki ke hoʻopili pololei me nā lapalapa, a ua kūpono lākou no ka uhi ʻana o nā kiln ʻoihana like ʻole.
6. ʻO nā pōhaku lepo pōʻalo alumina oxide. Hoʻohana nui ʻia nā pōhaku lepo pōleʻa alumini oxide no ka hoʻohana lōʻihi ma lalo o 1800 ℃. Loaʻa iā ia ke kūpaʻa kemika maikaʻi a me ke kūpaʻa corrosion i nā wela kiʻekiʻe. Ke hoʻohālikelike ʻia me nā pōhaku lepo māmā ʻē aʻe, ʻoi aku ka kiʻekiʻe o ka wela o ka hana, ka ikaika kiʻekiʻe, a me ka haʻahaʻa haʻahaʻa haʻahaʻa. ʻO 50% ~ 60% ka haʻahaʻa ma mua o nā huahana refractory dense o ka haku like, a hiki ke kū i ka hopena o nā lapalapa wela.
