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,resulting in a coagulation of the particles of the
coal slime.OH- and Ca(OH)\-2 don't act directly on the coagulation of the coal slime water.
