Chaw tsim tshuaj paus tus nqi calciumalumina cement7-16-2
Calciumalumina Maas yog cement nrog calcium calcium lossis calcium aluminium yog nws cov pob zeb tseem ceeb. Nws yog ua los ntawm ntuj aluminium los yog muaj alumina thiab calcium carbonate (limestone) raws li ib qho kev faib ua feem, uas yog tsim los ntawm kev hlawv lossis hluav taws xob yaj.
Cov khoom xyaw thiab pawg: Calibium Maas tuaj yeem muab faib ua cov hmoov av tsw qab (al2o3) thiab ntshiab li aluminium calement xiss (Al2o3302-82%, CAO 19-23%) ob pawg. Kev ua kom zoo li Alternat Maas tau muab faib ua cov hom qis (FE2O3 <2%) thiab High -Speed Rail hom (FE2O37-16%). Tsawg -Rail -Type Aluminium Cement tuaj yeem faib ua Alum Av Maas (Al2o359% rau 61%, CAO 27-31%), thiab qis -CalCium Aluminium aluminium acid xiss (al2o3 65-70%, CAO 21 rau 24%). Ntshiab txhuas cala ills tuaj yeem faib ua ob hom: al -o3 72-78%) thiab ultra-hom (al2o3 78-855%). Ib qho ntxiv, muaj nrawm thiab nyuaj thaum ntxov muaj zog aluminium calasent.CAS: 65997-16-2
