Breakage Characteristics of C. I. Disperse Red 60 Under an Ultrasound Field

The characteristics of ultrasonic breakage are investigated quantitatively by measuring the particle size of a dye dispersion subjected to ultrasound radiation. The breakage of dye particles strongly depends on the liquid medium temperature, the ultrasound intensity, and the dye dispersion volume. The degree of breakage is also determined by the total sonic energy per unit volume radiated to the dye dispersion, regardless of factors such as ultrasound radiation intensity, dye dispersion volume, and ultrasound radiation time. There exists a temperature at which the breakage rate reaches a maximum.
