Ultrasonic cleaning machine must use

In order to better use the ultrasonic cleaner, here are some things you must see:

1. When should I change the cleaning solution?

When cleaning, it can be seen that the obvious cleaning solution is reduced, or when the cleaning solution is obviously dirty or fails, the cleaning solution should also be replaced.

2. What cleaning fluid should I use for the ultrasonic cleaner?

Ultrasonic cleaning solutions that are currently used are mixtures of various cleaning ingredients, wetting agents and other reactive ingredients. Choosing the right cleaning solution is critical to effectively cleaning the workpiece and eliminating unwanted reactions. You can provide the best cleaning solution for you.

3. Will ultrasonic cleaning damage the workpiece ?

Ultrasonic cleaning is safe for most workpieces. The energy generated by the implosion of thousands of bubbles per second is enormous, but because the energy is concentrated in extremely small areas, the entire cleaning process is safe. The most cautious consideration for safety should be the choice of cleaning fluid. The potential damage of the cleaning fluid to certain workpiece surfaces may increase due to the use of ultrasound. Ultrasonic cleaning is not recommended for the following gemstones: opal, pearl, emerald, tanzanite, malachite, emerald, lapis lazuli and coral.

4. What kind of cleaning solution can't be used?

Do not use flammable or low flash point solutions. The energy released by cavitation is converted into heat and kinetic energy and produces high temperatures in the solution, which is very dangerous for flammable liquids. Acidic cleaning solutions and bleaches should normally be avoided as they can damage stainless steel tanks or cause hazards; however, they can be used when used in indirect cleaning processes, such as large beakers as indirect cleaning vessels.

5. What is “cavitation”?

"Cavitation" is the phenomenon in which millions of tiny bubbles ( or voids ) form and burst rapidly in a liquid. The "cavitation" is produced as a result of the interaction of high and low pressure waves formed by high frequency sound waves ( ultrasonic waves ) . In the low pressure phase, the bubbles become a little bit larger, and in the high pressure phase, they are compressed and imploded.

6. How can I achieve the best ultrasonic cleaning effect ?

There are a number of conditions that determine the final cleaning effect. The most important thing is to choose the right cleaning solution, wash it at the right temperature for the right time, and choose the right size and type of ultrasonic cleaner.

7. Why do you have to keep the cleaning fluid within the height allowed by the level indicator ?

Ultrasonic cleaning systems are “tuning” systems, and improper liquid levels can change the cleaning environment, affecting system frequency, reducing cleaning efficiency and damaging equipment. Maintaining the proper level allows the workpiece to be in optimal flow and protects the heater and shaker from damage due to overheating.

8. What is the best cleaning temperature?

Heating usually provides the speed of cleaning, while the chemical composition of most cleaning solutions achieves optimum cleaning at a certain temperature. The best way to find the optimum temperature is to experiment. Typically, the optimum cleaning temperature will be between 50 °C and 65 °C.

9. What is the length of the cleaning time ?

Changes in cleaning time depend on factors such as dirt, cleaning fluid, temperature and cleanliness requirements. When the ultrasonic cleaning was started, almost at the same time, it was observed that significant dirt was removed. Adjusting the cleaning time is the simplest ( and often misused ) method to compensate for changes that occur during the process. Although an experienced operator can try to ensure the time required for a new cleaning process, it is often necessary to verify the actual application by selecting cleaning fluids and contaminated workpieces.

10. Why do I need a special cleaning solution for cleaning?

The purpose of using the cleaning solution is to break the connection between the dirt and the workpiece, and the use of water alone does not result in cleaning. The main purpose of ultrasonic cavitation is also to assist the cleaning fluid for cleaning. A cleaning solution contains a variety of ingredients that achieve optimal cleaning results. For example, reducing the surface tension of the liquid can increase the cavitation strength, while an ultrasonic cleaning solution can contain a wetting agent or a surfactant component.

11. What is the heating device used for?

The enormous energy generated by cavitation produces heat, and the primary purpose of the heating device is to maintain the temperature within the cleaning fluid during the cleaning process.

12. What is “direct” and “indirect” cleaning ?

Direct cleaning usually means that the workpiece is cleaned in a cleaning tank filled with cleaning fluid, and the workpiece is usually placed in a perforated tray or tool basket. The limitation of direct cleaning is the need to select cleaning fluids that do not damage the ultrasonic cleaning bath. Indirect cleaning is to place the workpiece to be cleaned in a beaker or a tray without holes. The beaker or tray contains the solution instead of being directly installed in the cleaning tank. When indirect cleaning is selected, verify that the water level in the tank is maintained at the standard position.
