ʻO ka wehewehe ʻana o Corundum Mullite Castable
ʻO Corundum mullite refractory castable kahi ʻano o ka ikaika kiʻekiʻe unshaped refractory mea no ke kūʻai aku ma RS Company, hiki ke hoʻohana ʻia i ka kiln sima. Hiki i nā corundum mullite castables ke hana i nā waiwai kiʻekiʻe e like me ka ikaika ʻoki kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, ke kū ʻana o ka haʻalulu wela, ka ʻaʻahu a me ke kūpaʻa erosion kemika i ka uhi ʻana o ka paila mana nui a me nā mea wela kiʻekiʻe. refractory corundum mullite castable hiki ke hoʻohana 'ia i loko o ke kila umu ahi, sima kiln, aniani kapuahi, hao hana kapuahi, ceramic tunnel kiln a pela aku.
Nā waiwai o Corundum Mullite Castable
- ikaika nui,
- ʻO ke kūpale ʻaʻahu ikaika,
- Kūleʻa maikaʻi i ka erosion,
- ʻOi aku ka paʻa o ka haʻalulu wela,
- Kūleʻa wela kiʻekiʻe.
Ka Hana Hana ʻana o Corundum Mullite Castable
ʻO ka mea nui o ka corundum mullite castable he māmā alumini oxide aggregate, kiʻekiʻe kiʻekiʻe maʻemaʻe maoli mullite ore, a me ka calcium aluminate cement e like me ka mea hoʻopaʻa. Hana ʻia ka corundum mullite refractory castable ma o ke ahi wela kiʻekiʻe e ka umu ʻoihana holomua. ʻO ka ikaika flexural corundum mullite a me ka ikaika compressive e hoʻonui mua a emi iho a laila me ka piʻi ʻana o ka mahana mālama wela. A inā he 5% ka mana o ka alumina micro, hiki i ka ikaika flexural i luna.
Hoʻohui ʻia o Corundum Mullite Castable
ʻOi aku ka ʻike o Al2O3 ma mua o 90%, a ʻo ka corundum mullite insulation castable me ka corundum e like me ka pae aniani nui i hui pū ʻia me nā dispersants kūpono, nā coagulants, nā fibers stainless steel, i hoʻohui ʻia e like me ke ʻano koʻikoʻi. ʻO Refractory corundum mullite castable he nui nā hiʻohiʻona, e like me ka ikaika wela kiʻekiʻe, ka pale ʻana a me ka anti-scour, ka hoʻokele wela kiʻekiʻe, ke kūpaʻa haʻalulu wela, ke kūpaʻa corrosion, ke sila maikaʻi a me ka condensation mua.

- Noi o Corundum Mullite Castable
- ʻO Corundum mullite refractory castable he mau hiʻohiʻona o ka hoʻonui like ʻana, maikaʻi ke kūʻē ʻana i ka wela wela, ke kūpaʻa o ke ana wela, ka ikaika wela kiʻekiʻe, ka refractoriness kiʻekiʻe ma lalo o ka ukana, ka haʻahaʻa haʻahaʻa kiʻekiʻe kiʻekiʻe creep rate, kiʻekiʻe paʻi ikaika, haʻahaʻa linear dimensional loli rate, kiʻekiʻe paʻakikī, maikaʻi. kū'ē i ka ʻino kemika, spalling a ʻaʻahu kūʻē. Ma muli o ia mau huapalapala, a me ka corundum mullite insulation castable ka lōʻihi i ka hoʻohana 'ia a ua hoʻohana nui 'ia i loko o ka 'oihana kiln, kiʻekiʻe wela umu ahi a me na mea nui o ka wela wela, e like me:
- ʻO ka paila, ka umu ahi, ka umu wela wela, ka umu wela,
- Kiln tunnel seramika, kiln sima, puhi lanahu,
- ʻO ka puka kapuahi, ka puka hānai, nā kapuahi kila, nā kapuahi hao,
