【摘要】 根据硅灰石矿物的物化性能 ,选择了有效改性药剂OAA和NT 2 0 1,确定了湿法磨矿中表面改性处理的最佳工艺条件及参数 ,制取了硅灰石纯度 >95 %、细度 - 10 μm含量 >95 %的高纯、超细、功能化微粉填料。该工艺实现了提纯、超细粉碎、表面改性的有机统一更多还原

【Abstract】 Effective modifiers, OAA and NT-201, are selected for modification wollastonite.The optimum conditions and parameters for modification in wet-grinding process are determined by testing. The functional wollastonite powders with the grade over 95% and size over 95%-10μm is prepared. In this technique, ultra-fine pulverizing and surface modification process are combined.更多还原
