| 摘 要： | 水-TEA-TBP溶剂体系中,结合表面活性剂复配体对工业级Mg(OH)2进行水热处理,得到粒度分布窄、粒径小、分散性好的改性Mg(OH)2。讨论了溶剂体系中水-TEA-TBP的配比、Mg(OH)2浓度(mol/L)、矿化剂MgC l2用量(%)、表面活性剂用量(%)、水热温度(℃)和水热时间(h)等因素对Mg(OH)2的改性影响。

| Abstract: | The industrial-grade Mg(OH)2 was modified by hydrothermal treatment and mixed surfactant in the water-TEA-TBP solvent system.The results indicated that the modified Mg(OH)2 has narrow particlesize distribution,small particle size and good dispersion.The effect factors on modified Mg(OH)2,including the ratio of water,TEA and TBP in the solvent system,concentration of Mg(OH)2(mol/L),percentage of MgCl2(%),percentage of surfactants(%),temperature of hydrothermal treatment(℃) and hours of hydrothermal treatment... |
