| 摘 要： | 利用硬脂酸、硅烷偶联剂对重晶石粉进行表面改性。改性后的重晶石矿物表面的疏水性得到明显了改善；分析了改性时间、改性温度和改性剂用量等因素对改性效果的影响。应用实验表明：改性超细粉在铜版纸涂布和油漆中可以替代沉淀硫酸钡。

| Abstract: | Barite powder was modified with stearic acid and silicane. The activity index indicated that modified barite powder had a good hydrophobic. The effect of modification was discussed separately through the processing time, processing temperature and quantity of reagents. Application experimentation show that modified barite powder takes the place of precipitated barium sulfate in offset coated paper, coating and paint etc. |
