E koho i nā piliki insulation mullite māmā a i ʻole nā ​​​​piliki refractory i ke kūkulu ʻana i ka umu? 2

ʻO nā ʻokoʻa nui ma waena o nā pōhaku mullite insulation a me nā pōhaku refractory penei:

1. Hana hoʻokaʻawale: ʻO ka conductivity thermal o nā piliki insulation ma waena o 0.2-0.4 (awelika wela 350 ± 25 ℃) w/mk, ʻoiai ʻo ka conductivity thermal o nā piliki refractory ma luna o 1.0 (awelika wela 350 ± 25 ℃) w/mk Hiki ke hoʻoholo ʻia he ʻoi aku ka maikaʻi o ka hana insulation o nā piliki insulation ma mua o nā piliki refractory.
2. Ke kū'ē ahi: ʻO ke kū'ē ahi o nā piliki ahi insulation mullite ma lalo o 1400 degere, ʻoiai ke kū'ē ahi o nā piliki refractory ma luna o 1400 degere.
3. Ka nui o ka paʻa:Nā pōhaku ahi hoʻokaʻawale MulliteʻO ka maʻamau, he mau mea hoʻomehana māmā, me ka nui ma waena o 0.8 a me 1.0g/cm3, ʻoiai ʻo ka nui o nā piliki refractory ma mua o 2.0g/cm3. Ma keʻano laulā, he ikaika mechanical kiʻekiʻe ka piliki refractory, lōʻihi ke ola lawelawe, kūpaʻa kemika maikaʻi, ʻaʻohe hopena kemika me nā mea a me ke kūpaʻa wela kiʻekiʻe. Hiki i kona mahana pale wela kiʻekiʻe ke hiki i 1900 ℃. He kūpono ia no nā umu hoʻololi wela kiʻekiʻe a me ka haʻahaʻa, nā mea hoʻoponopono hou, nā mea hoʻololi hydrogenation, nā pahu desulfurization, a me nā umu methanation i nā mea kanu mea hoʻouluulu, he kuleana kona i ka hoʻopuehu ʻana i ke kinoea a me ka wai, ke kākoʻo, ka uhi ʻana, a me ka pale ʻana i nā catalysts. Hiki ke hoʻohana ʻia i nā umu pahū wela a me nā lako hoʻololi hoʻomehana i ka ʻoihana kila.
Loaʻa i nā piliki paʻa ʻole nā ​​​​​​maikaʻi o ka nui o ka nui, ka ikaika kiʻekiʻe, ke kūpaʻa maikaʻi o ka ʻaʻahu, ke kūpaʻa maikaʻi i ka pala, ka coefficient haʻahaʻa o ka hoʻonui wela, ka pono wili kiʻekiʻe, ka hoʻemi ʻana i ka walaʻau maikaʻi, ke ola lawelawe lōʻihi, nā mea haumia ʻole, a pēlā aku. He mea wili kiʻekiʻe ia e kūpono no nā mīkini wili like ʻole.
He mea koʻikoʻi ka ʻokoʻa ma waena o nā piliki refractory a me nā piliki ahi insulation mullite, ʻoiai he ʻokoʻa ko lākou ʻano hana, ka laulā, a me ka hana. E hoʻohana ʻia nā mea like ʻole ma nā kūlana like ʻole. I ke koho ʻana i nā mea, pono mākou e hoʻoholo i ka mea refractory i kūpono no kā mākou hoʻohana ponoʻī e pili ana i ko mākou kūlana maoli.
