Paraffin Wax Powder Production by Ultrasonic Atomization

Abstract

This work was aimed to study wax powder production from the paraffin melt by using ultrasonic atomization process. Effects of atomization operating parameters: melt temperature, melt flow rate and ultrasonic vibration amplitude on particle size distribution, median particle size, production yield and morphology of the atomized paraffin wax powder were investigated. It was evidenced from the experimental results that the particle size distribution of paraffin wax powder was narrowed and the median particle size was decreased with decreasing the melt flow rate, the vibration amplitude and increasing the melt temperature. The production yield of paraffin wax powder tended to increase with decreasing the melt flow rate, the vibration amplitude and increasing the melt temperature. The atomized paraffin wax powder was spherical shape with rough surface and some particles were formed as satellites.
