Factors affecting ultrasonic cleaning time


The cleaning time of ultrasonic cleaning equipment varies with many factors. So, there is no simple answer that covers all situations. In general, 2-10 minutes to remove most of the general surface dirt, if very dirty or difficult to deal with the place, it may take up to 20 minutes. Of course, there is no way to clean it completely in a few seconds, because ultrasonic cleaning is a process that takes time to clean.

Let's take a look at some of the factors that affect ultrasonic cleaning time!

1. The type of contamination on the surface of the material. Different contaminants require different cleaning times.

Loose pollutants such as dust, metal chips, and soot are easy to shed because their molecules do not interact strongly with surfaces.

Oils and waxes take longer to remove. Their molecules form bonds with metals and plastics and sometimes with each other. These bonds need to be broken by the force of the imploding bubble before the contaminant can fall off.

Carbon deposits, rust, and other oxides are the most difficult to remove and therefore require the longest cleaning time.

2. Quantity of pollutants.

More dirt takes more time to remove. Pre-rinsing parts to remove most contaminants helps speed up the process.

3. Surface properties of materials.

The adhesion of pollutants to the surface of different materials is also different.

4. Different cleaning fluids.

The choice of cleaning fluid will have a direct impact on the cleaning time, which requires the user in the use of ultrasonic cleaning, according to their materials need to choose the different pollutants, should be the fastest, the cleanser that most readily reacts with contaminants.

5. The life of the cleaning fluid.

A fresh cleaning solution that is free of particles and debris will work better than one that has been used many times before.

6. The temperature of the cleaning fluid.

For many applications, the cleaning fluid in an ultrasonic cleaner needs to be heated. Each cleaning solution has its optimum operating temperature. It is usually located between 122-149 & deg; F (50-65 & deg; C) .

7. The power of an ultrasonic cleaning machine.

For cleaning dirt and other large particles, of course, ultrasonic cleaning equipment chooses more power (per unit volume). If you want to clean small particles on lightly contaminated objects, you can use less ultrasonic power.

8. The frequency of the ultrasonic cleaning machine.

Lower ultrasonic frequencies produce larger bubbles and are more powerful and clean large surfaces well. Higher frequencies produce thinner, weaker bubbles, which are good at cleaning small, complex areas.

In general, there are too many factors that affect the cleaning time. This requires us to verify the actual cleaning time based on the actual situation, the characteristics of the customer's product, as well as the state of pollutants, and the effect the customer wants to achieve.
