Ka wehewehe ʻana o ka pōhaku pehu Alumina
ʻO ka pōhaku ahi pehu alumina kahi ʻano hou o nā mea hoʻomehana wela kiʻekiʻe a hana ʻia me ka alumina ʻoihana i loko o ka umu uila ma o ka hoʻoheheʻe ʻana a me ka puhi ʻana. ʻO ke ʻano o ka kristal pōhaku paʻakikī pehu alumina he microcrystal a ʻo ke kino nui he pehu alumina hiki ke hana ʻia i nā ʻano huahana āpau me nā ʻano like ʻole no ka lawelawe ʻana i ka mahana kiʻekiʻe loa o 1800 ℃ me ka ikaika mechanical kiʻekiʻe a me ka haʻahaʻa haʻahaʻa.
Nā Waiwai o ka Piliki ʻŌpū Alumina
- Māmā ke kaumaha,
- Ka mālama ʻana i ka ikehu,
- ʻO ke kumukūʻai kūkulu haʻahaʻa,
- Ke kūpaʻa wela kiʻekiʻe,
- Hoʻololi linear hoʻomehana hou haʻahaʻa,
- Kū'ē maika'i i ka ha'alulu wela.
Kaʻina Hana Hana o ka Brick Bubble Alumina
Hoʻohana ka pōhaku ahi bubblle alumini i ka pōpō bubble alumina ma ke ʻano he mea nui, ka pauka ultrafine hana kiʻekiʻe e like me ka mea hoʻopili a me nā mea olaola e like me ka mea hoʻopaʻa ma o ka hoʻoheheʻe ʻana a me ka hoʻomaloʻo ʻana, a laila hoʻopau ʻia i loko o ka umu uila wela kiʻekiʻe.
Ka Pōmaikaʻi o ka Alumina Bubble Brick
Loaʻa i ka piliki ahi bubblle alumini nā hiʻohiʻona o ka insulation wela a me ka conductivity thermal haʻahaʻa, hiki ke hopena i ka hopena insulating wela nui, hoʻemi i ka hoʻonele wela a hoʻomaikaʻi i ka pono thermal. ʻO ka hoʻohana ʻana i ka piliki refractory bubblle alumini hiki ke mālama i ka ikehu kiʻekiʻe a hiki i ka 30%. a ʻo ka mahana lawelawe o ka poloka bubble alumina he kiʻekiʻe a hiki i ka 1750 ℃. Maikaʻi ke kūpaʻa thermal a haʻahaʻa ka wikiwiki hoʻololi linear reheating, hiki i ka poloka bubble alumini ke hopena i ke ola lawelawe lōʻihi.

Ka hoʻohana ʻana o ka pōhaku lepo Alumina
ʻO ka piliki pehu alumina kahi ʻano mea refractory koʻikoʻi loa no ke kūʻē ʻana i ke kiʻekiʻe o ka mahana a me nā koi kūikawā o nā kūlana no ka umu a me ka umu, kahi i hoʻohana nui ʻia e like me ka piliki insulating no ka papa insulation o ka umu a me ka umu, a hiki ke hoʻohana ʻia ka piliki pehu alumini no nā linings lawelawe i ka hana ʻana i ka quartz maʻemaʻe kiʻekiʻe no ka ʻoihana uila e like me nā linings tile ceramic i loko o nā turbines kinoea a me nā linings kākoʻo i loko o nā reactors.
Mea Hana Piliki ʻŌpū Alumina mai ka Hale Hana Kūpaʻa RS
ʻO ka hale hana kūpaʻa RS ma ke ʻano he mea hana piliki pehu alumina ʻoihana ma Kina, he nui nā pono hoʻokūkū ma ka mākeke. Inā he koi kāu no nā piliki pehu alumini, a i ʻole he mau nīnau kāu e pili ana i ka piliki ahi pehu alumini e pili ana i nā ʻōkuhi kino a me nā kemika, e ʻoluʻolu e kelepona mai iā mākou no ka manuahi, e hāʻawi mākou iā ʻoe i nā piliki kūpaʻa pehu alumini kiʻekiʻe.
