ʻO nā hiʻohiʻona a me ka hoʻohana ʻana i ka brick insulation māmā

Ke hoʻohālikelike ʻia me nā pōhaku makamae maʻamau, ʻoi aku ka maʻalahi o nā pōhaku insulation māmā i ke kaumaha, ʻoi aku ka nui o nā pores liʻiliʻi i loko, a ʻoi aku ka nui o ka porosity. No laila, hiki iā ia ke hōʻoiaʻiʻo i ka liʻiliʻi o ka wela e nalowale mai ka paia o ka umu ahi, a ua hoʻemi ʻia nā kumukūʻai wahie. ʻOi aku ka liʻiliʻi o ka waiho ʻana o ka wela i nā pōhaku māmā, no laila ʻoi aku ka wikiwiki o ka hoʻomaʻamaʻa ʻana a me ka hoʻoluʻu ʻana o ka umu i kūkulu ʻia me nā pōhaku māmā. ʻO nā pōhaku lepo hoʻomaʻamaʻa māmā ka mea kūpono no ka pae wela o 900 ℃ ~ 1650 ℃.

Nā hiʻohiʻona opōhaku lepo māmā
1. Low thermal conductivity, haʻahaʻa wela wela, haʻahaʻa haumia maʻiʻo
2. ʻO ka ikaika kiʻekiʻe, ke kūpaʻa haʻalulu wela maikaʻi, ke kūpaʻa corrosion maikaʻi i ka waika a me ka lewa alkali
3. Kiekie ana pololei pololei
Ka hoʻohana ʻana i nā pōhaku lepo māmā
1. ʻO nā mea like ʻole o ka umu ahi ʻenehana, e like me: annealing furnace, carbonization furnace, tempering furnace, aila hoʻomaʻemaʻe ʻana i ka umu wela, ka umu ahi, ka umu hoʻoheheʻe, ka tunnel kiln, etc.
2. Kākoʻo ʻana i nā mea hoʻoheheʻe no nā kapuahi ʻoihana like ʻole.
3. Hoemi i ka umu ahi.
