摘要
石灰在煤泥水混凝中的作用机理：石灰对煤泥水的混凝作用不是补给了ＯＨ－，而是提供了大量的Ｃａ２＋．Ｃａ２＋通过压缩双电层，破坏了煤泥颗粒的稳定性，从而使煤泥颗粒发生凝聚．ＯＨ－和Ｃａ（ＯＨ）２对煤泥水的混凝不直接起作用．
This paper researches the action mechanism of lime on the coagulation of coal slime water. The result of investigation indicates that the coagulation action of lime on the coal slime water is to supply Ca2+,but not OH-. The Ca2+ destroy the stability of the coal slimes by compressing twin electrical layer,thence the coacervation of coal slimes is led. OH- and Ca (OH)2 don't act directly on the coagulation of coal slime water.
