Parameters of ultrasonic dispersion of polymer-composite solutions
- 19 Downloads
Conditions allowing the formation of three types of characteristic cavities in liquid via ultrasonic cavitations have been considered. The effect of the ultrasonic-field parameters on the dispersion efficiency has been analyzed, and the choice of criteria for the evaluation of the quality of steering and dispersion of a polymer-composite material (PCM) for reconstruction of body parts of automotive engineering has been grounded. The conditions for effective dispersion of a PCM solution have been established on the basis of the sound-pressure amplitude upon ultrasonic treatment and based on the maximum permissible level of the solution in an ultrasonic bath.
