ultraäänisointi

Ultraäänisointi, also known as ultrasonic cleaning, is a process that uses high-frequency sound waves to agitate a cleaning fluid. This agitation creates tiny bubbles in the liquid, a phenomenon called cavitation. When these bubbles collapse, they generate powerful micro-jets and shock waves that effectively dislodge and remove contaminants from the surface of objects immersed in the fluid. The process is particularly effective for cleaning intricate or irregularly shaped items where manual cleaning would be difficult or impossible.

The frequency of the ultrasonic waves used typically ranges from 20 kHz to 400 kHz. Higher frequencies produce smaller cavitation bubbles, which can reach into very small crevices and pores, while lower frequencies generate larger bubbles capable of removing more robust contamination. The cleaning fluid itself can be water-based or solvent-based, depending on the nature of the contaminants and the material being cleaned. Detergents or other cleaning agents are often added to the fluid to enhance the cleaning effectiveness.

Applications for ultraäänisointi are widespread across various industries. It is commonly used in jewelry cleaning, electronics manufacturing for cleaning printed circuit boards, medical device sterilization, automotive parts cleaning, and in laboratories for cleaning delicate instruments. The gentleness of the process, combined with its thoroughness, makes it a preferred method for cleaning items that might be damaged by abrasive cleaning techniques. The equipment involved typically consists of an ultrasonic transducer, a tank to hold the cleaning fluid, and a generator that powers the transducer.
