Kaolinite was ground with a vibration mill under different conditions to examine grinding characteristics and mechanochemical effect, The results showed that the particle size reduces and specific surface increses with increasing time. The effect of mechanical treatment on the structure of kaolinite was examined by XRD and IR techniques. The structural disorder was observed. The morphology of particles was studied through scanning electronic microscopy. It is realized, that particles losed their original shapes after mechanical treatment. The DTA diagram exhibited that the temperatures of thermal effect of samples become lower and. lower as the grinding time increased, thus indicating the structure alteration. The results also showed that environmental conditions have great influences on the mechanochemistry in fine grinding process. And the grinding process might be considerably improved by adding a grinding aid. N(CH_2CH_2OH)_3 into the system.

研究了高岭土的细粉碎过程与机械化学效应。实验结果表明,粉碎过程能使物料发生粒径变小、比表面积增大,并且产生晶体结构畸变、热效应温度降低等一系列机械化学变化。以KB(a)-192 h试样为例,代表性粒径从3.2 μm降至0.95μm,比表面积从1.27 m~2/g增至3.38 m~2/g,脱去结构水的温度降低28℃。液相介质和助磨剂对粉体的机械化学变化都有很大影响。就热效应温度而言,粉碎处理192h后,KE系列试样降低12℃,KB系列试样降低17℃,可见丙酮比乙醇更有利于机械化学变化。KB(a)试样降低28℃,比KB系列试样降得更低,说明引入三乙醇胺作助磨剂,能促进机械化学反应。

On the basis of the mechano-chemical effect of ultrafine grinding with stirred mill, a new process of mechano-chemical modification of powders is developed. Mechanism of mechano-chemical modification is analyzed through IR, XPS, DR-IR, DTA and viscosity in this paper. The results indicate that surfacial modification can be obtained through modifier's adsorption, connection, and bond effect on powder surface. Ultrafine grinding can effectively promote the success of mechano-chemical modification.
