Trial Number 17

Trial Purpose:

To evaluate products on supplied parts

Date Run:

05/13/2004

Experiment Procedure:

Three products were selected based  on results from previous trials.  All products were used heated to 160 F on a hot plate in 250 ml beakers. One product, Solvon PB,  cleaned one part with the metal working fluids (Quench Oil, RI 780) for 15 minutes in the vapor degreaser.  The other two products cleaned two parts, one with Quench oil and the other with the varnish mix.  Each part was cleaned in each solution for 15 minutes in the bench top vapor degreaser.

Trial Results:

Part Observation
1 Some of the oils may have not been cleaned due to the parts were wrapped with a wire (for suspending in vapors
2  Ruler Varnish was removed within seconds of coming into contact with the vapors.
3  Punch Some of the oils may have not been cleaned due to the parts were wrapped with a wire (for  suspending in vapors)
4  Ruler Varnish was removed within seconds of coming into contact with the vapors
5  Punch Some of the oils may have not been cleaned due to the parts were wrapped with a wire (for suspending in vapors

Success Rating:

Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.

Conclusion:

The three cleaners appeared to be very effective in removing the various contaminants from the supplied parts.
