Determination of Laser Particle Size Distribution of Ultra-fine WC Powder AITranslate
Abstract AITranslate
Ultra-fine WC powder contains a high surface energy in the developed suriace area,which exhibits a strong adsorption capacity for gases,liquids or particles,and is easily aggregated into secondary particles spontaneously,which leads to the sample using conventional laser particle size analysis method can not be effectively dispersed.The laser particle size distribution curve is always with a "trailing".In this paper,we ground the sample for 1 hour,then added the sample after grinding into the anhydrous ethanol,and into the external ultrasound machine for 10 minutes.Finally,the sample was tested.The particle size distribution curve of this test method is normal distribution,with good precision,and the relative standard deviation of laser particle size distribution characteristic value (d (10),d (50)and d (90))is less than 5%.
