Choose lightweight mullite insulation bricks or refractory bricks when building a furnace? 2

Ko nga rereketanga nui i waenga i nga pereki mullite insulation me nga pereki aukati ko enei e whai ake nei:

1.Ko te mahinga: Ko te tikanga o te pereki whakapawera i waenga i te 0.2-0.4 (toharite pāmahana 35 ℃) pereki.

3. Kiato:Ko nga pereki ahi whakamaumaru mulliteare generally lightweight insulation materials, with a density generally between 0.8 and 1.0g/cm3, while refractory bricks have a density generally above 2.0g/cm3. In general, the refractory brick has high mechanical strength, long service life, good chemical stability, no chemical reaction with materials and good high-temperature resistance. Ko te teitei o te wera wera ka tae ki te 1900 ℃. It is suitable for high and low temperature shift furnaces, reformers, hydrogenation converters, desulfurization tanks, and methanation furnaces in fertilizer plants, it plays a role in dispersing gas and liquid, supporting, covering, and protecting catalysts. Ka taea hoki te whakamahi i roto i nga oumu pupuhi wera me nga taputapu huringa whakawera i roto i te ahumahi maitai.
Ko nga pereki whakaraerae te painga o te tino kaha, te kaha o te reanga, te tino pai o te whakatipuranga waiariki, te koiora ratonga.
Ko te rereketanga i waenga i nga pereki whakaheke me nga mullite he mea nui nga pereki ahi ahi, na te mea he rereke te taiao, te whānuitanga, me te mahi. Ka whakamahia nga rauemi rereke i roto i nga ahuatanga rereke. I te wa e kowhiri ana i nga rawa, me whakatau ko tehea rawa whakaahuru e tika ana mo taatau ake whakamahi i runga i to maatau ahuatanga.
