炭素材料粒度组成控制的理论与实践

THEORY AND PRACTICE OF CONTROLLING THE PARTICLE SIZE AND ITS DISTRIBUTION OF CARBON MATERIALS

简要介绍了Andreassen颗粒堆积理论,并结合生产实践,讨论了实际生产中所用的粒度组成与这一理论的联系与差异。与Andreassen方程所确定的粒度组成相比,实际配方中细颗粒和粗颗粒用量较大,中颗粒用量较小。

The Andreassen particle packing theory was introduced briefly. The particle size and its distribution predicted by the Andreassen theory is compared with that measured directly in producing carbon graphite electrodes. The relation and difference between the theoretical and the practical results are discussed. In comparison to the particle size distribution determined by the Andreassen equation, the amount of the coarse and fine particles of the practical formulation is large, but the amount of the medium ones is small.
