Using PolyGone in an Ultrasonic Cleaning Tank

Here are some guidelines for using PolyGone products with ultrasonic cleaning devices.  The initial work was done with an industrial unit running at 80 kHz with heating capability.  The small "table top" units are designed more for jewelry cleaning than industrial use.  RPM Technology does work with several manufacturers who produce higher performance units designed for more industrial applications.  The main issue is power - wattage.  In addition, an industrial unit is 100% stainless steel, no plastic.  As for frequency, the general rule is lower frequency, more etching, more energy; higher frequency, less etching, less energy.  40 KHz is average and the most popular frequency.
 

1. Use regular tap water.  DO NOT use DI water in the bath.

2. Add a few drops of dishwashing liquid.  This lowers to surface tension of the water for more effective energy transfer.

3. Make sure the container holding the PolyGone does not sit on the bottom of the tank.  The container must be at least ½" off the bottom for effective energy transfer.

4. Turn the unit on for at least 30-40 minutes prior to placing the object into the PolyGone for cleaning.  This gives the material a chance to degas, this improves performance.

5. Using the units heater also increases performance.  RPM recommends a temperature no higher than 50 Celsius.  However, the biggest bang for the buck is the ultrasonics.

6. To prolong the life of the solvent, keep the beaker covered at all times.  This limits the evaporation of the chemistry from the beaker.
