乙氧基镁催化剂粉末粒度及粒度分布测定的研究

Study on Determination of Particle Size and Particle Size Distribution of the Magnesium Ethylate Catalyst Powder

用乙醇做分散介质,用激光粒度测定仪测定四个乙氧基镁催化剂粉末试样的粒度及粒度分布,测试快速、准确。试验结果显示乙氧基镁(德国)催化剂粉末粒度最小,粒度分布集中,在四个样品中质量最好,试验结果令人满意。

Using alcohol as disperse medium, the particle size and particle size distribution of four magnesium ethylate catalyst powder samples were determined with the laser particle size analyzer. The test was fast and accurate. The particle size of the magnesium ethylate （Germany） catalyst powder sample was the smallest and the particle size distribution was concentrated. The quality of MGE （Germany） was the best. The result was satisfactory.
