Ultrasonic cleaning or ultrasonic washing is a technological method that uses high-frequency sound waves (usually between 20 kHz and 400 kHz) to remove dirt, grease, rust, and other contaminants from the surfaces of various materials. This process occurs in special devices called ultrasonic baths. The energy generated in ultrasonic baths creates a large number of micro air bubbles that are present in the ultrasonic cleaning solution and then transfer into the liquid, causing rapid heating and extremely high pressure. During low-pressure periods, microscopic bubbles form, while during high pressure, these bubbles collapse or explode. These micro bubbles are capable of removing dirt, residues, and bacteria adhered to objects.
To simplify, during ultrasonic cleaning, under the influence of ultrasonic waves, the liquid compresses and expands, leading to the formation of cavitations, which results in the creation of vacuum bubbles. Each bubble strikes the object being cleaned with a pressure of about 650 to 700 bar, detaching accumulated dirt particles from the homogeneous material.
Due to its efficiency, speed, and ability to clean delicate items without damage, this method is used in many industries.
Based on all the above, we can say that ultrasonic cleaning is a clean and one of the most cost-effective methods for cleaning surfaces, equipment, and materials, providing users with comfort and impeccable results. Additionally, this cleaning technique does not cause any damage to the structure or properties of materials and is a good method for domestic, professional, or business use.
