人们在粉末的生产和应用过程中发现:①烧结制品的原料粉体的粒子越细,其强度越高,并且随着粒度分布范围的缩小,强度波动值减少;②用于高分子合成材料如塑料等的助剂或添加剂的粉末原料,其粒度对制品的强度同样产生很大的影响,而两者之间
People found in the process of powder production and application: ① Sintered products of raw materials, the smaller the particle size, the higher the intensity, and with the size distribution of the narrowing, reducing the intensity fluctuations; ② for polymer materials such as Plastics and other additives or additives powder raw materials, the particle size of the strength of the same products have a great impact, and between the two
