Trial Purpose:
To evaluate one cleaner on all four contaminants using vapor degreasing
Date Run:
05/14/2004Experiment Procedure:
One product was selected base on client input from previous testing. The product was heated to boiling (160 F) in a vapor degreasing chamber on a hot plate. Twelve preweighed aluminum coupons were coated four different contaminates, thee coupons per contaminant. Coupons were reweighed to determine the amount of soil added. The coupons were cleaned for 5 minutes in the vapor zone, then removed and allowed to cool to room temperature outside the chamber. Final weights were recorded and efficiencies were calculated.
The contaminants removed were: Soltex Polybutene 32 (9003-29-6)
Cargill, Inc Canola Oil (120962-03-0)
Nisseki SAS 40 oil (27776-01-8, 612-00-0, 103-29-7, 101-81-5)
C.P. Hall Co. Plasthall ESO oil (8013-07-8)
Trial Results:
All four contaminants were removed using Ensolv in a vapor degreaser for five minutes. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
| Contaminant | Initial wt | Final wt | % Removed |
| Soltex | 0.7328 | 0.0000 | 100.00 |
| 0.6829 | 0.0003 | 99.96 | |
| 0.8973 | 0.0001 | 99.99 | |
| Cargill | 0.1078 | -0.0002 | 100.19 |

| 0.1887 | -0.0001 | 100.05 | |
| Nisseki | 0.0501 | 0.0008 | 98.40 |
| 0.0873 | 0.0002 | 99.77 | |
| 0.0968 | -0.0001 | 100.10 | |
| CP Hall | 0.4715 | -0.0001 | 100.02 |
| 0.5001 | 0.0002 | 99.96 | |
| 0.2575 | 0.0001 | 99.96 |
Success Rating:
Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.Conclusion:
Vapor degreasing with Ensolv appears to work very well on the four supplied soils. Piloting on actual parts should be performed at this time.
