Trial Number 2

Client Number 7

Project Number 2

Trial Purpose:

To clean client supplied parts using cleaner from previous trials.

Date Run:

07/01/1999

Experiment Procedure:

Four parts were viewed using an UVP Inc. Black light, Model UVL-56 longwave UV-366nm for fluorescence.  The cleaner from the previous trial, listed in Table 1, was used to clean the client supplied parts using Ultrasonics (Crest 40 kHz ultrasonic tank model 4Ht 1014-6) at room temperature for five minutes.  Parts were rinsed using a tap water spray at 100 F for 30 seconds and air dried for one hour.  Parts were then viewed again under the black light to determine if the contaminants had been removed.  Figure 1 displays the parts cleaned.

Trial Results:

The wax was removed from the parts in less than five minutes of ultrasonic cleaning.  There was no fluorescing under the black light.

Success Rating:

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

Conclusion:

Envirosolutions Bio-T Max was very successful in the removal of wax from the various parts submitted to the lab for testing.  All four parts have been sent back to the client for evaluation.
