A Brief Overview of Ways to Prevent Damage to Workpieces During Ultrasonic Cleaning

Using an ultrasonic cleaner, inspect the product you're cleaning and then confirm the ultrasonic frequency with the cleaning agent used. If your ultrasonic cleaner has multiple compartments with features like heating, drying, or slow extraction, there are several factors to consider: temperature, cleaning solution concentration, and cleaning duration.

Typically, machinery and hardware parts are cleaned with 28KHz ultrasonic degreasing, optical lenses with 40K, laboratory research with 100K, and LCD semiconductor material components with 1MHz or higher. Most manufacturers now offer ultrasonic cleaning machines that can adjust the output power. Considering the cleaning rules and duration, suitable output power can be selected.

Wax oil typically requires an alkaline cleaning solution, with the temperature maintained around 75 degrees for optimal efficiency and cleaning quality. Some solvents offer a selection of choices. The lower the ultrasonic frequency of a cleaning machine, the easier it is to create cavitation in the liquid, leading to better results. Higher frequencies with strong ultrasonic specificity are suitable for cleaning delicate objects.

Higher ultrasonic power leads to stronger cavitation effects, faster processing speed, and better actual results. However, for products with smoother surfaces and higher precision, prolonged high-power cleaning can cause "cavitation erosion" on the surface objects.

Choosing ultrasonic cleaning, there are generally two types of detergents, namely chemical organic solvents and water-based detergents. By combining the oxidizing effect of the substance with the physical effect of ultrasonic treatment, both can effectively and rationally clean objects. Typically, ultrasonic erosion at 30°C-40°C yields excellent results. The detergent's effectiveness increases with temperature, and it is commonly used at temperatures ranging from 40°C to 60°C during detailed ultrasonic cleaning applications.
