ʻO ka hana nui o nā brick insulation ka mālama ʻana i ka wela a hoʻemi i ka nalowale o ka wela. ʻAʻole pili pono nā pōhaku lepo me ka lapalapa, a ʻo ka mea maʻamau e pili pono ana ke ahi me ka lapalapa. Hoʻohana nui ʻia nā pahu ahi e kū i ka lapalapa o ka ʻala. Hoʻokaʻawale ʻia ʻo ia i ʻelua ʻano, ʻo ia hoʻi indefinite Unshaped refractory material a me shaped refractory material.
Mea Hoʻohuʻi ʻole
ʻO nā mea hoʻoheheʻe castables he ʻāpana pauka i hui ʻia me nā ʻano aggregates a i ʻole aggregates a me hoʻokahi a ʻoi aʻe nā mea hoʻopili. Pono e hui ʻia ka hoʻohana ʻana me hoʻokahi a ʻoi aku ka wai, me ka wai ikaika.
Mea Hoohuoi i ke ano
I nā kūlana maʻamau, loaʻa i ke ʻano o nā brick refractory ka nui maʻamau, hiki ke hana ʻia e like me nā koi o ka mea kūʻai aku.
ʻO nā ʻokoʻa nui ma waena o nā brick insulation & firebricks
1. Hoʻokō Insulation
He 0.2-0.4 ka nui o ka conductivity thermal o nā pōhaku lepo insulation (mehana awelika 350±25°C) w/mk, a ʻo ka conductivity thermal o ke ahi ahi ma luna o 1.0 (mehana maʻamau 350±25°C) w/mk No laila, ʻo ka insulation thermal. ʻOi aku ka maikaʻi o ka hana ʻana i nā pōhaku insulation ma mua o nā pōhaku ahi.
2. Hoʻopaʻapaʻa
ʻO ka refractoriness o ka brick insulating ma lalo o 1400 degere, a ʻo ka refractoriness o ka brick refractory ma luna o 1400 degere.
3. ʻO ka mānoanoa
ʻO nā pōhaku insulation nā mea hoʻonā māmā, ʻo ka nui o nā pōhaku insulation ma ke ʻano he 0.8-1.0g/cm3 a ʻoi aku ka nui o nā pōhaku refractory ma luna o 2.0g/cm3.
Ka hopena
I ka hōʻuluʻulu ʻana, ʻo ka brick refractory ka ikaika mechanical kiʻekiʻe, ke ola lōʻihi o ka lawelawe ʻana, ke kūpaʻa kemika maikaʻi, ʻaʻohe hopena kemika me ka mea a me ke kūpaʻa wela kiʻekiʻe, a hiki i ka wela wela wela ke hiki i 1900 ° C. Pono pono nā pōhaku lepo refractory no ka hoʻohana ʻana i nā mea hoʻololi kiʻekiʻe haʻahaʻa wela, nā mea hoʻololi, nā mea hoʻololi hydrogenation, nā pahu desulfurization, a me nā umu methanation o nā mea kanu mea kanu kemika e pāʻani i ka hoʻopuehu ʻana i nā wai kinoea, kākoʻo, uhi, a pale i nā catalysts. Hiki ke hoʻohana ʻia nā pōhaku lepo ahi i loko o nā kapuahi wela a me nā mea hoʻololi wela i ka ʻoihana kila.
Loaʻa i nā mea ahi nā mea maikaʻi o ke kiʻekiʻe kiʻekiʻe, ka ikaika kiʻekiʻe, ke kūpaʻa ʻana, ka pale ʻana i ka corrosion maikaʻi, ka hoʻonui haʻahaʻa haʻahaʻa haʻahaʻa, ka maikaʻi o ka wili ʻana, ka leo haʻahaʻa, ke ola lawelawe lōʻihi, a me nā mea hoʻohaumia ʻole. He mea wili maikaʻi ia i kūpono i nā mīkini wili like ʻole.
ʻOkoʻa loa nā pōhaku lepo refractory a me nā pōhaku insulation, ʻaʻole like ko lākou hoʻohana ʻana i ke kaiapuni, ka laulā a me ka hana. E hoʻohana ʻia nā mea like ʻole ma nā wahi like ʻole. I ke kūʻai ʻana i nā mea pono, pono mākou e hoʻoholo i ke ʻano o nā mea refractory kūpono no kā mākou hoʻohana ponoʻī e like me ko mākou kūlana maoli.
