Ultrasonic Power – Reaching the Limits?

Ultrasonic power has been a topic of much discussion ever since ultrasonic technology was first used for cleaning nearly a century ago. The quest has always been for more ultrasonic power, the thought being that higher power would produce better cleaning results.  As I have discussed earlier, higher ultrasonic power typically requires an increase in the amplitude …

Questioning Particle Generation Due to Cavitation Erosion as a Source of Contamination

Ultrasonic cleaning is widely used for removing particles from surfaces.  It is generally agreed that the high energy of implosions of cavitation bubbles break the bonds holding particles to the surface being cleaned and that liquid motion (streaming) carries the particles away once they have been dislodged.  However, it is also well known that ultrasonic cavitation …

Heat – Definitions and Concepts

Temperature has been identified as one of the important variables in cleaning – arguably the most important.  So I thought it might be worth some time to develop a little understanding of heat – – especially how it is generated and transmitted. Heat is a form of energy.  The amount of heat contained in an object …

Exhausting Gasses Produced by the Cleaning Process

In many industrial cleaning processes it is necessary to exhaust emissions that unavoidably result from the cleaning process.  The reasons for exhaust can take on a large range – Remove heat that would otherwise raise the temperature in the cleaning area Remove humidity that would otherwise raise the humidity in the cleaning area Remove toxic fumes that might otherwise be dangerous …

How do you measure surface tension?

In the world of industrial cleaning technology we talk about surface tension a lot! So much so, in fact, that it is hard to enter into any discussion of cleaning without having the subject of surface tension arise.  In cleaning chemistry, for example, we are always looking for lower surface tension to promote penetration of small surface features …
