钾离子和钙离子协同抑制作用的探讨

Study on Synergistic Inhibition of Potassium and Calcium Ion

为深入探索钾盐和钙盐对泥页岩水化作用的抑制潜能,文中就钾盐和钙盐,特别是混合盐对泥页岩的抑制作用进行了实验研究。结果表明,K^+和Ca^(2+)抑制页岩分散的能力顺序与离子浓度有关;Ca^(2+)抑制泥页岩分散作用随浓度的变化规律与K^+的不同。实验还发现,对某些泥页岩而言,当混合盐溶液达到合理的离子配比时,具有离子协同抑制作用。

To understand the inhibitive potential of potassium and calcium ion to the hy-dration of shale , the inhibition property of potassium ion , calcium ion , and mixed solution of above ions are studied . It is shown that the inhibition ability of the said ions is related to their concentration , mixed ion solution possesses synergistic inhibition at optimal ratio for some shale .
