摘要
应用超音速气流使硅灰石、硬脂酸粉体互相碰撞-劈裂-粉碎-断健，其新鲜表面带离子键或活性点，彼此间发生化学反应或化学吸附，粉碎-活化在同一时间完成。红外吸收光谱分析结果证明硅灰石表面有硬脂酸接枝物。
When supersonic speed air flow acts on wollastonite and stearic acid,the latter canbe collided,cloven,pulverized and broken bond. Ionic bond formed on fresh surface of wollastonite and stearic acid can be reacted each other. Pulverization and activation were complishedin the same time. The results of IR shown that grafts of stearic acid remain on the surface ofthe wollastonite.
