Tlhaloso ea Corundum Mullite Castable
Corundum mullite refractory castable ke mofuta oa thepa e matla e sa bōpeheng sebopeho e rekisoang Khamphaning ea RS, e ka sebelisoang ka ontong ea samente. Li-castable tsa Corundum mullite li ka etsa thepa e phahameng joalo ka matla a ho sila a phahameng, botsitso ba mocheso o phahameng, ho hanyetsa mocheso, ho hanyetsa ho tsofala le ho hoholeha ha lik'hemik'hale ka har'a lesela la boiler e kholo ea seteishene sa motlakase le lisebelisoa tse ling tse phahameng tsa mocheso. Corundum mullite refractory castable e ka sebelisoa ka ontong ea tšepe, ontong ea samente, ontong ea khalase, ontong ea ho etsa tšepe, ontong ea kotopo ea ceramic le tse ling.
Matlotlo a Corundum Mullite Castable
- Matla a phahameng,
- Ho hanyetsa ho tsofala ho matla,
- Ho hanyetsa khoholeho ea mobu hantle,
- Ho ba le botsitso bo botle ba ho sisinyeha ha mocheso,
- Ho hanyetsa mocheso o phahameng.
Ts'ebetso ea Tlhahiso ea Corundum Mullite Castable
Lisebelisoa tse ka sehloohong tse tala tsa corundum mullite castable ke aggregate e bobebe ea aluminium oxide, oli ea tlhaho e hloekileng ea mullite ea boleng bo holimo, le samente ea calcium aluminate e le moemeli oa ho kopanya. corundum mullite refractory castable e etsoa ka ho chesoa ha mocheso o phahameng ke sebōpi se tsoetseng pele sa indasteri. matla a corundum mullite flexural le matla a khatello lia eketseha pele ebe lia fokotseha ebe li eketseha ka mocheso oa kalafo ea mocheso. 'Me ha matla a alumina a manyane a le 5%, matla a flexural a fihla holimo.
Sebopeho sa Corundum Mullite Castable
Dikahare tsa Al2O3 di feta 90%, mme ho kwahela ha corundum mullite ho ka tjhesehetswang ka corundum e le karolo e ka sehloohong ya kristale ho kopantswe le di-dispersants tse loketseng, di-coagulant, difaeba tsa tshepe e sa ruseng, tse kopantsweng ho ya ka foromo e tiileng. Corundum mullite e ka tjhesehetswang ka corundum e na le dibopeho tse ngata, tse kang matla a mocheso o phahameng, ho hanela ho tsofala le ho thibela ho hlajwa, ho tsamaisa mocheso o phahameng, ho hanyetsa ho tshoha ha mocheso, ho hanyetsa ho bola, ho kwala hantle le ho kobeha ha pele.
