1. When should the cleaning fluid be changed?

When cleaning, you can see a significant reduction in the cleaning fluid and should be replaced; or when the cleaning fluid is significantly dirty or ineffective, the cleaning fluid should also be replaced.

2. What cleaning solution should I use?

Ultrasonic cleaning fluids commonly used today are mixtures of various cleaning ingredients, wetting agents and other reactive ingredients. Selecting the proper cleaning fluid is critical to effectively cleaning workpieces and eliminating unwanted reactions. Branson can provide you with the best cleaning solution.

3. Will ultrasonic cleaning damage my workpiece?

Ultrasonic cleaning is safe for most workpieces. The energy from the implosion of thousands of bubbles per second is enormous, but the entire cleaning process is safe because the energy is concentrated in an extremely small area. The most prudent consideration for safety should be the choice of cleaning fluid. The potential damage of cleaning fluids to some workpiece surfaces may be increased by the use of ultrasonic waves. Ultrasonic cleaning is not recommended for the following gemstones: opal, pearl, emerald, tanzanite, malachite, emerald, lapis lazuli, and coral.

4. What cleaning fluid should I not use?

Do not use flammable or low flash point solutions. The energy released by cavitation is converted into heat and kinetic energy and generates high temperature in the solution, which is very dangerous for flammable liquids. Acidic cleaning fluids and bleach should generally 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 beakers used as indirect cleaning vessels.

5. What is "cavitation"?

"Cavitation" is the rapid formation and bursting of millions of tiny air bubbles (or cavities) in a liquid. "Cavitation" occurs as a result of the interaction of high and low pressure waves due to high frequency sound waves (ultrasonic waves). During the low pressure stage, the bubbles grow a little bit larger, while at the high pressure stage they are compressed and imploded.

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

There are many conditions that can determine the final cleaning effect, the most important of which are choosing the right cleaning solution, cleaning at the right temperature for the right time, and choosing the right size and type of ultrasonic cleaner.

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

Ultrasonic cleaning systems are "tuned" systems, and improper fluid levels will alter the cleaning environment, affecting system frequency, reducing cleaning efficiency and damaging equipment. Maintaining the proper fluid level keeps the workpiece in the best fluid flow and protects the heater and vibrating box from overheating damage.

8. What is the optimum cleaning temperature?

Heating usually provides the speed of cleaning, and while most cleaning fluids contain chemicals that achieve optimal cleaning results at a certain temperature, the best way to find the optimal temperature is to experiment. Typically, the optimum cleaning temperature will be between 50°C and 65°C.

9. What is the length of cleaning time?

Cleaning times vary depending on factors such as dirt, cleaning fluid, temperature and cleanliness requirements. When the ultrasonic cleaning was started, almost at the same time, it could be seen that the obvious dirt was removed. Adjusting the cleaning time is an easy (and often misused) way to compensate for changes that occur in the process. Although an experienced operator can try to guarantee the time required for a new cleaning process, it is usually necessary to verify in the actual application by selecting the cleaning fluid and contaminating the workpiece.

10. Why do you need special cleaning fluid for cleaning?

The purpose of using the cleaning fluid is to break the connection between the dirt and the workpiece, and the use of water alone cannot achieve the cleaning effect. The main purpose of ultrasonic cavitation is to assist the cleaning solution in cleaning. A cleaning solution contains multiple ingredients for optimum cleaning results. For example, reducing the surface tension of the liquid can increase the cavitation strength, and an ultrasonic cleaning fluid will contain a wetting agent or surfactant component.

11. What is the heating device used for?

The huge energy generated by cavitation generates heat, and the main purpose of the heating unit is to maintain the temperature in the cleaning fluid during the cleaning process.

12. What are "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 installed in a tray or tooling basket with holes. The limitation of direct cleaning is the need to select cleaning solutions that will not damage the ultrasonic cleaning tank. In indirect cleaning, the workpiece to be cleaned is placed in a beaker or a tray without holes, and the beaker or tray is filled with a solution, rather than directly in the cleaning tank. When selecting indirect cleaning, confirm that the water level in the tank is maintained at the standard position.
