Trial Purpose:
To evaluate successful cleaners using ultrasonic energy
Date Run:
12/18/2001Experiment Procedure:
The seven successful cleaners and the client's current cleaner from the previous trial were again diluted to 5% in 600 ml beakers using DI water. Each was heated to 130 F in a Crest 40 kHz ultrasonic tank filled with water.
Twenty-seven preweighed coupons were coated with the lubricant using a plastic eye dropper and allowed to sit for 2 hours. The coupons were weighed. Three coupons were cleaned in each solution for 5 minutes using ultrasonic energy. Following the cleaning, a 30 second tap water rinse at 120 and a 1 minute heat gun drying at 500 F was performed. Coupons were allowed to return to room temperature and reweighed. Efficiencies were calculated and recorded.
Contaminant: Fuchs Renocut 127 (mineral oil)
Trial Results:
Valtech Valtron SP 2275 again had the highest efficiency, removing 99.99% of the lubricant from the aluminum coupons. Four other products removed over 99%, including the client supplied cleaner. The following table lists the results for each coupon cleaned.
| Cleaner | Coupon 1 | Coupon 2 | Coupon 3 | Average |
| Brulin | 99.78 | 98.17 | 99.40 | 99.12 |
| Buckeye | 95.98 | 97.81 | 97.65 | 97.15 |
| Envirosolutoins | 98.54 | 98.60 | 99.39 | 98.84 |
| Gemtek | 96.82 | 96.13 | 97.74 | 96.89 |
| Innovative | 99.98 | 99.34 | 99.54 | 99.62 |
| Today | 99.87 | 99.92 | 99.90 | 99.90 |
| Valtech | 99.98 | 100.02 | 99.97 | 99.99 |
| Texo | 99.88 | 99.60 | 99.66 | 99.71 |
Success Rating:
A follow up test, usually based on company input.Conclusion:
The use of ultrasonics increased the effectiveness for all but one cleaner. The five most effective cleaners will be used to clean supplied parts from the client.
