在相同试验条件下,用水做分散介质,用激光粒度测定仪测定三个氧化锆催化剂粉末样品的粒度及粒度分布,比较了三个样品的粒径大小和粒度分布情况。试验结果显示,氧化锆2号样品粒度最小,粒度分布集中,1号样次之,3号样粒度最大,粒度分布最分散。

Under the same testing condition and using the water as disperse medium,the particle size and its distribution of the three kinds of jargonia catalyst powder samples were determined by means of the laser particle size analyzer. The particle size and its distribution of the three samples were compared. The particle size of the No.2 sample was the smallest and the particle size distribution was concentrated. The No.1 sample was seondary. The particle size of the No.3 sample was the largest and the particle size distribution was dispersed.
