Precautions for using the ultrasonic washing machine to clean stainless steel


When using ultrasonic cleaning stainless steel, the surface of the parts made of stainless steel is usually very hard, and the lowest ultrasonic frequency can provide a strong cleaning effect. Therefore, the low ultrasonic frequency will perform well on these components, but its cleaning performance will also be affected by the nature and characteristics of pollutants.

Although the ultrasonic cleaning system used for stainless steel parts is not sensitive to the frequency of use, the system characteristics, such as heating baths, system power supplies, and adding cleaning agents or solvents to the bath, can cause differences between full and excellent cleaning performance. Cleaning. The time spent by parts and pollutants that remove all traces will be affected. Experienced ultrasonic equipment manufacturers can help what types of systems are recommended and ensure that the selected ultrasonic cleaning system provides the best performance.

How the characteristics of ultrasonic cleaning affect cleaning performance

Stainless steel parts can be cleaned at ultrasonic frequencies as low as 26 kHz to 40 kHz because they are not subject to mechanical damage or surface pitting. At these frequencies, the system produces large cavitation bubbles and has a strong scrubbing effect to remove contaminants. Ensuring quick and thorough cleaning can be challenging when parts are heavily contaminated with caked sediment or oil or grease.

In addition to being strong and hard, stainless steel is not affected by most solvents or detergents and is not sensitive to heat. Depending on the contaminant, the stainless steel part can be cleaned more effectively by heating the cleaning solution or by adding a mild detergent to help dissolve the contaminant to be removed. If parts are contaminated with several different substances, a combination of detergent and heat may be required.

For heavy contamination with hard deposits, solvents can usually be found that soften or dissolve specific substances, thus accelerating the removal by ultrasonic cleaning of bubbles. For oily or oily deposits, mild cleaners can break the adhesion that binds contaminants to stainless steel surfaces, making them easier to remove by ultrasonic cleaning.

Many organic pollutants from hardened deposits are difficult to remove. Heating the cleaning solution below the boiling point usually softens the sediment and makes it easier to remove. Since ultrasonic cleaners with this capability can be designed and configured, it is important to define the cleaning applications the system will be used for before purchasing. The type of contaminants to be removed, the detergent or solvent needed to remove them, and the possible use of the heating tank all affect the final decision on the use of the ultrasonic cleaning system.
