Cov cib magnesia muaj ntau tshaj 90% magnesium oxide cov ntsiab lus thiab siv periclase ua lub hauv paus tseem ceeb crystalline. Cov cib magnesite tuaj yeem muab faib ua ob pawg ntawm Burnt Magnesia Cib thiab Chemical Bonded Magnesite Cib. Cov cib magnesite muaj kev ua tau zoo heev ntawm qhov kub siab tshaj plaws lub zog kho tshuab thiab qhov ntim ruaj khov. Thiab tuaj yeem ua haujlwm hauv qhov kub siab ntawm 1750 ℃, Magnesite cib yog cov khoom zoo tshaj plaws rau kev siv lub qhov cub iav.
Cov Khoom ntawm Magnesia Cib
- Cov tshuaj refractorine siab,
- Kev tiv thaiv alkaline slag,
- Kev tiv thaiv kev yaig thiab zoo heev tiv thaiv oxidation,
- Siab refractoriness nyob rau hauv load,
- Lub zog kho tshuab siab,
- Kev ruaj khov ntawm qhov kub thiab txias.
Cov Txheej Txheem Tsim Khoom Magnesia Cib
Cov cib magnesia muaj ob hom: cov cib magnesite hlawv thiab cov cib magnesite sib txuas ua ke. Cov cib magnesite hlawv yog ua los ntawm cov khoom siv raw ntawm periclase, tom qab hlawv nrog 1550 ~ 1600 ℃ kub los ntawm kev sib tsoo, sib tov, yaj thiab molding. Cov khoom ntshiab siab muaj qhov kub hlawv tshaj 1750 ℃. Cov cib magnesite tsis hlawv yog ua los ntawm kev ntxiv cov tshuaj lom neeg tsim nyog los ntawm kev yaj, molding thiab ziab.
Kev faib tawm ntawm Magnesia Cib
Vim muaj cov tshuaj sib txawv ntawm cov cib magnesia, uas tuaj yeem muab faib ua ntau hom, thiab tag nrho cov cib no yog tsim los ntawm kev sintering. Raws li cov khoom siv raw sib txawv, cov cib magnesia tuaj yeem muab faib ua cov pawg hauv qab no:
Cib magnesia ib txwm muaj: pob zeb magnesite sintered.
Cib magnesia txuas ncaj qha: siab purity sintered magnesite.
Pob zeb Forsterite: peridotite
Cib magnesia calcia: sintered magnesite uas muaj calcium ntau.
Cib magnesia silica: pob zeb magnesite sintered silicon siab.
Cib Magnesia chrome: sintered magnesite thiab qee cov chrome ore.
Cib Magnesia alumina: pob zeb magnesite sintered thiab Al2O3.
