ʻO nā poloka hoʻoheheʻe alumina kiʻekiʻe no ka umu ahi hana
Hiʻona & Pōmaikaʻi
ʻO nā poloka insulating alumina kiʻekiʻe he mau mea refractory kūikawā i hoʻohana ʻia i nā noi wela kiʻekiʻe ma muli o ko lākou mau waiwai kūʻokoʻa. ʻO kekahi mau hiʻohiʻona nui o nā poloka insulating alumina kiʻekiʻe:
1. ʻO ka wela wela: He haʻahaʻa ko lākou conductivity wela, e hana maikaʻi loa iā lākou i ka hoʻohaʻahaʻa ʻana i ka wela a me ka mālama ʻana i nā wela kiʻekiʻe i nā umu a me nā kiln.
2. Mechanical ikaika: Hōʻike lākou i ka ikaika mechanical maikaʻi a me ke kū'ē i ka abrasion, e hōʻoiaʻiʻo ana i ka lōʻihi a me ka lōʻihi i nā kūlana paʻakikī.
3. Māmā: ʻOiai ko lākou ikaika a me ka lōʻihi, ʻoi aku ka maʻalahi o nā poloka insulating alumina kiʻekiʻe, kahi e maʻalahi ai ka mālama ʻana a me ke kau ʻana.
4. Dimensional Stability: Hoʻomau lākou i ko lākou ʻano a me ke kūpaʻa ʻana ma lalo o nā kūlana wela kiʻekiʻe, e hōʻemi ana i ka deformation a me ka haki.
5. ʻO ka ikaika o ka ikehu: Ma ka hāʻawi ʻana i ka insulation maikaʻi loa, kōkua kēia mau poloka i ka mālama ʻana i ka ikehu a me ka hōʻemi ʻana i nā kumukūʻai hana i nā kaʻina hana wela.
Hoʻohana maʻamau
Hoʻohana maʻamau ʻia ʻo "Vibration Cast Fireclay Block for Glass Furnace" no ka pale ʻana i ka lalo a me nā ʻaoʻao o nā umu aniani. ʻAʻole wale kēia mau pōhaku ahi ahi e hoʻokaʻawale, pale i ka hoʻolaha ʻana i waho o ka wela a mālama i kahi kūlana wela kiʻekiʻe i loko o ka umu aniani, akā loaʻa pū kekahi mau hiʻohiʻona ikaika kiʻekiʻe. Hāʻawi kā lākou kaʻina hana hoʻoheheʻe vibration i kēia mau pōhaku lepo a me ka hana refractory maikaʻi loa, e hiki ai iā lākou ke pale i nā wela kiʻekiʻe a me nā hopena i hana ʻia i ka wā o ka hana o ka umu aniani, e hōʻoia ana i ka paʻa a me ka hilinaʻi i ka wā lōʻihi o ka hana.
