摘要
借助差示微分扫描量热仪等分析手段 ,得出了溶液结晶法从烟气脱硫残渣中制备α型半水石膏的结晶机理 :烟气脱硫石膏首先经过脱水生成 β型半水石膏 ,再由
The mechanism of crystallization of flue gas desulfurization sludge waste into α form calcium sulfate hemihydrate through differential scanning calorimetry(DSC) is obtained. The FGD gypsum is converted into β form hemihydrate at first, and then β form hemihydrate is converted into α form hemihydrate.
