Next-gen Cleaning – The Power Of Ultrasound

Ultrasonic cavitation has long been a major factor contributing to the acceleration of many technological stage, especially in the processes of cleaning in chemical and metallurgical industries. This is where the demand for managing cavitation perfectly is really high. Ultrasonic cavitation in the liquid depends on its density, viscosity, temperature, molecular weight, compressibility, gas content, the presence of microscopic inclusions, frequency and intensity of ultrasonic vibration, static pressure and other factors. For example, cavitation in the water is more strong than in other liquids. The gas in the liquid increases the efficiency cavitation phenomena. With increasing temperature, liquid cavitation intensity increases up to a maximum, after passing which it begins to fall. Efficacy cavitation increases with increasing power, but decreases with increasing frequency of the ultrasonic vibrations. At very high frequencies of ultrasonic cavitation is impossible to obtain.

The scientists have developed a range of technologies that have made ultrasonic cleaning a very common and indispensable in various industries. In recent years, a trend, known as high-amplitude ultrasonic cleaning, was formed and now it is gaining momentum. A characteristic feature of it is the substantial increase in the amplitude fluctuations of the source and as a consequence of changes in the energy characteristics of radiation changing the parameters of acoustic cavitation and liquid processing is now possible. The innovative devices and complex equipment are now quite available due to the efforts of such companies as Ultrasonic and Hilsonic, UK largest ultrasonic cleaner manufacturers.

Where is it applied?

Ultrasound cleans a variety of metal, glass, ceramic and other details. For example, the bearing rings are easily cleaned by polishing paste, printed circuit boards – from the flux components, and rolled sheet – from the heat scale, optical parts and precious stones – from polishing agents, small details – from burrs, medical instruments, glass containers – from various contaminants and so on. d.

Particularly thorough cleaning is necessary for details of rapidly devices, bearings, electrical contacts, relays, fuel equipment, as well as electronic components, computer equipment, watch mechanisms, optical devices, and so on. High-quality cleaning of parts from contamination plays a crucial role in modern mass production processes.

Here are some examples of ultrasonic cleaning: in heavy machinery factories ultrasonic method is used to clean parts from the fuel pump. Ultrasonic installation performed well allows to replace time-consuming manual washing and improve the quality of treatment and improve working conditions. From the long run, the method allows to press for significant operational expenses cut.

To clear the offset printing plates, it was immersed in an alkali, and then wash the hair with a brush under running water. It takes a lot of time. In addition, a worker breathing noxious fumes. When applied ultrasound, clear the form of steel a few minutes. The device, which came up with the designers, consists of two baths. In one of them with the help of ultrasound with the old image of the foil is removed, rinsed in another with her remaining alkali and dirt.
