How to choose the operating frequency of ultrasonic cleaning machine?

Low-frequency ultrasonic waves (20kHz - 40kHz): Cavitation bubbles are larger, release more energy when they burst, and have a violent impact. Suitable for removing heavy dirt (such as oil stains, metal debris).

What is the optimal operating temperature range for ultrasonic cleaning machines?

Water-based cleaning fluid: This is the most commonly used. For most water-based cleaning agents, the optimal temperature range is usually between 50°C and 60°C. In this temperature range, the viscosity of dirt (especially grease and oil) decreases, making it easier to peel and emulsify.

Which products are not suitable for cleaning with an ultrasonic cleaner?

The following products are not suitable for ultrasonic cleaning:Soft materials: Surfaces can be damaged by cavitation (soft metals, polished surfaces).Surface coatings/treatments: Can be peeled off (paint, plating, non-stick coatings, printing).Porous/fragile structures: Can absorb liquids or break internally (organic gemstones, fractured gemstones, soft plastics).Precise/complex structures: Vibrations can interfere.

What is the role of the heating function of an ultrasonic cleaning machine?

Enhanced cleaning effect (core function):Reducing liquid surface tension: Heating the cleaning liquid reduces its surface tension. The lower the surface tension, the easier it is for ultrasound to produce cavitation in the liquid (the process of forming and breaking tiny bubbles), resulting in more bubbles with greater energy.

How to choose the size of a household ultrasonic cleaner?

Core principles for choosing the sizeMatch the volume of the item: The length/width of the cleaning tank must be 1.5 times greater than the maximum size of the item to ensure uniform coverage of the sound waves.Reserve liquid space: The water level must completely submerge the item and leave at least 2cm of heightTaking into account storage convenience: The mini type can be placed in a cabinet or desktop corner, and.
