EVALUATION METHOD OF SUSPENSION LIQUID

摘要

PROBLEM TO BE SOLVED: To provide a new evaluation method of suspension liquid by means of ultrasonic attenuation. SOLUTION: The method is characterized by evaluating the dispersive properties of suspension liquid based on an ultrasonic attenuation by passing an ultrasonic wave with a specific frequency through a suspension liquid and measuring the ultrasonic attenuation after passed the suspension liquid.
