ʻO ka hoʻolauna ʻana i nā pōhaku lepo māmā alumini kiʻekiʻe

ʻO nā pōhaku lepo māmā alumini kiʻekiʻe nā huahana refractory wela-insulating i hana ʻia me ka bauxite ma ke ʻano he kumu nui me ka ʻike Al2O3 ʻaʻole i emi iho ma mua o 48%. ʻO kāna kaʻina hana ʻo ke ʻano foam, a hiki ke hoʻohui ʻia i ke ʻano hoʻohui. Hiki ke hoʻohana ʻia nā brick insulation māmā alumini kiʻekiʻe no nā ʻāpana insulation masonry a me nā ʻāpana me ka ʻole o ka hoʻoheheʻe ikaika a me ka hoʻoheheʻe ʻana o nā mea hoʻoheheʻe wela kiʻekiʻe. Ke hoʻopili pololei ʻia me nā lapalapa, ʻaʻole ʻoi aku ke kiʻekiʻe o ka mahana o ka ʻili o ka alumini kiʻekiʻe ma mua o 1350 °C.

ʻO nā hiʻohiʻona o ke alumini kiʻekiʻe māmā insulation brick
Loaʻa iā ia nā hiʻohiʻona o ke kūpaʻa wela kiʻekiʻe, ikaika kiʻekiʻe, haʻahaʻa haʻahaʻa haʻahaʻa, porosity kiʻekiʻe, haʻahaʻa haʻahaʻa thermal conductivity, kiʻekiʻe kiʻekiʻe wela, a me ka hana insulation wela maikaʻi. Hiki iā ia ke hoʻemi i ka nui a me ke kaumaha o nā lako wela, e hoʻopōkole i ka manawa hoʻomehana, e hōʻoia i ka mahana o ka umu ahi like ʻole, a hoʻemi i ka nalowale o ka wela. Hiki iā ia ke mālama i ka ikehu, mālama i nā mea kūkulu hale umu a hoʻolōʻihi i ke ola lawelawe kapuahi.
Ma muli o kona porosity kiʻekiʻe, haʻahaʻa haʻahaʻa haʻahaʻa a me ka hana insulation thermal maikaʻi,kiʻekiʻe alumini pōhaku māmā hoʻokaʻawalehoʻohana nui ʻia e like me nā mea hoʻopihapiha hoʻopihapiha hoʻopihapiha i loko o ka lumi ma waena o nā pōhaku refractory a me nā kino kapuahi i loko o nā kiln ʻoihana like ʻole e hōʻemi i ka hoʻoheheʻe ʻana o ka umu ahi a loaʻa ka ikehu kiʻekiʻe. ʻO ka helu heheʻe o ka anorthite he 1550°C. Loaʻa iā ia nā hiʻohiʻona o ka haʻahaʻa haʻahaʻa, liʻiliʻi ka hoʻonui ʻana i ka wela, ka haʻahaʻa haʻahaʻa haʻahaʻa, a me ka noho paʻa i ka hōʻemi ʻana i nā lewa. Hiki iā ia ke hoʻololi i ka pālolo, silika, a me nā mea refractory alumini kiʻekiʻe, a ʻike i ka mālama ʻana i ka ikehu a me ka hoʻemi ʻana.
