Trial Purpose:
To evaluate five cleaners using ultrasonics
Date Run:
04/01/2002Experiment Procedure:
The five cleaners from the previous trial that caused a weight increase of the wax were used at the same dilutions, temperature and time. Each solution was de-gased in a Crest 40 kHz ultrasonic tank heated to 110 F. Fifteen preweighed coupons were coated with beeswax and allowed to cool before taking a dirty weight. Three coupons were cleaned in each solution for 5 minutes using ultrasonic energy. Coupons were rinsed at 110 F for 15 seconds using tap water and dried for 1 minute at 300 F using the Master Appliance heat gun.Final weights were recored and efficiencies were calculated for each solution.
Trial Results:
Three of the products showed significant improvement with the addition of ultrasonic energy in the cleaning process. Texolite jumped to a 95% efficiency, Polyspray increased to 73.5% and Inproclean averaged 62.52%. The other two removed less than 10% of the wax. The table below lists the results for each product.
| Cleaner | Coupon 1 | Coupon 2 | Coupon 3 | Average | Std Dev |
| EXP 1400 | -0.60 | 10.90 | 5.09 | 5.13 | 5.75 |
| Inproclean | 63.08 | 67.65 | 56.84 | 62.52 | 5.43 |
| Texolite | 90.59 | 94.63 | 99.79 | 95.00 | 4.61 |
| Polyspray | 75.19 | 68.75 | 76.55 | 73.50 | 4.16 |
| Uni Clear | 0.63 | 13.31 | -8.51 | 1.81 | 10.96 |
Success Rating:
A follow up test, usually based on company input.Conclusion:
The three products that improved with ultrasonics will be evaluated again at increased concentrations and cleaning times.
