Ultrasonic cleaning – method of cleaning the surface from solid and liquid contaminants is based on the excitation of ultrasonic frequency in the washing solution. The scientific basis for the creation and development of technology equipment ultrasonic cleaning laid in the field of acoustic cavitation conducted at the Acoustics Institute named after Academician Andreeva led by Professor Rosenberg.
Ultrasonic cleaning can replace manual labor, thereby speeding up the cleaning process, a high degree of surface smoothness virtually eliminate the use of inflammable and toxic solvents. Thus, according to Hilsonic statistics (the company is focusing its efforts on producing ultrasound equipment and ultrasonic cleaner models in particular) reports that despite the higher energy consumption and relatively high maintenance costs, its customers managed to cut down operational expenses by 18% on average.
Ultrasonic cleaning process provides its effect due to several phenomena that occur in the field of high intensity of ultrasound: acoustic cavitation, acoustic currents, radiation pressure and acoustic-capillary pressure.
Depending on the type of contamination, the predominant role is played by various purification processes. Thus, the destruction of contaminants occurs weakly interrelated, mainly under the influence of pulsating cavitation bubbles. On the edges of the film contamination pulsating bubbles, making intense vibrations, overcoming the cohesive forces of the film to the surface, penetrating the film and breaking it. Radiation pressure and acoustocapillary effect contribute to the penetration of cleaning solution in the micropores, bumps and blind channels. Acoustic flow is accelerated removal of dirt from the surface. If contamination is firmly connected to the surface, its elimination requires collapsing cavitation bubbles, creating a microshock impact to the surface.
