Ultrasonic cleaning, or not.

Ultrasonic cleaning, or not.

Ultrasonic cleaning, or not.

(OP)
One of our machines mixes polyurethane using a "turbine".
During a day's production a build up of product occurs. The turbine is soaked overnight in methylene chloride (dichloromethane) whick softens the polyurethane but doesnt remove it. The turbine is a complicated shape and hard to clean. Does anyone have any experience of ultrasonic cleaning: can you use any solvent with it, can you build your own equipment or is it best to buy off the shelf, is there a better solution I should be looking at.

RE: Ultrasonic cleaning, or not.

Hi Rob,

If your part is very large, then ultrasonic might not be the best idea.  We've looked at utilizing ultrasonic cleaners and we've found that they'll do an excellent job on cleaning a part . . . but it had to be a relatively small part.  In order to ultrasonically clean a part, it has to have a tank larger than the largest part you want to clean.  Another alternative you might want to consider is dry-ice blasting.  We have tried this too and it works extremely well.  And dry-ice would defintely be easier to handle from an EPA-point of view.  Hope that helps

Dear Rob,
You might wont to try Hi pressure hydrublasting with a gun at 30,000 psi to 36,000 psi.
we use hydrublasting to cleen big solid chunks of polymers
& it works fast & wonderfull. Their are so many hydroblasting cleaning companeys that would be very pleased to demonstrate their fast cleaning capabiliteis.
Regards,

Thank you for your replies. We have now sourced a solvent mix which seems to dissolve the build up overnight without the need for any agitation.
Thanks again.
