试论沉降法测定颗粒粒度及其分布

Determine particle size and the distrubution by sedimentation method

颗粒的粒度及其分布显著影响粉末的性质和用途,为了掌握生产中产品的质量,必须对粉末进行粒度分布的检测。详细介绍了沉降法的基本原理,实验方法、步骤和结果处理。试验和生产应用表明,粒度测定的方法多种多样,沉降法以其原理简单、易于操作而被广泛采用。

Particle size and the distribution influence performance and application of powder obviously. In order to control product quality, the measurement of particle size distrubution is necessary. The basic principle of the sedimentation method as well as experimental mothod ,steps and the results disposal were introduced in detail. Compared with other measure techniques, the sedimentation method has been applied abroad because of its simple principle and easy operation.
