摘要
重晶石具有密度大、化学性质稳定、无毒、易吸收辐射等优点,因而应用广泛。表面改性是提升重晶石性能并拓展其应用范围的重要手段,系统介绍了重晶石表面改性的3种方法:表面化学包覆法、机械力化学法、化学沉积法,以及3类表面改性剂:有机表面改性剂、无机表面改性剂、复合表面改性剂;总结分析了重晶石表面改性机理,并指出了重晶石表面改性方法及表面改性剂的未来研究方向。
Barite has been widely applied because of its strong points such as high density,stable chemical properties,toxic-free,ease to absorb radiation.As surface modification becomes a significant way of improving the performance of barite and expanding its application range,three approaches to surface modification on barite were systematically introduced as follows:surface chemical coating method,mechanical-chemical method,and chemical sedimentation method,meanwhile three types of surface modifiers:organic surface modifier,inorganic surface modifier,and composite surface modifier were also presented.Eventually the modification mechanism of different modifiers was summarized and analyzed,and the prospective research orientation of surface modification methods and surface modifiers on barite were proposed.
