研究了6种膨润土在蒸馏水、单一离子水溶液和复合离子水溶液中的膨胀体积,探讨了离子浓度对膨润土膨胀体积的影响.结果表明,单一离子水溶液浓度达到5g/L,复合离子水溶液浓度达到2g/L时,膨润土膨胀体积会显著减小;复合离子溶液对膨润土膨胀性能的影响最为显著.

The swelling volumes of six kinds of bentonite in water,unitary ion aqueous solution and compound ion aqueous solution were researched.The impact of ion concentration on the swelling of bentonite was probed.The results indicated that the swelling volume deceased greatly when the concentration of unitary ion solution reached to 5g/L,and the concentration of compound ion aqueous solution reached to 2g/L.The affect of compound ion aqueous solution on the swelling of bentonite was the most significant.
