Trial Purpose:
To evaluate top two products at higher temperature to achieve higher efficiencies.
Date Run:
08/17/2006Experiment Procedure:
Two products from the previous trial were diluted to 5% in 250 ml beakers using DI water and heated to 150 F in a Branson 3510 ultrasonic tank and degassed for 5 minutes.
Six preweighed coupons were coated with the green buffing compound using a handheld swab after heating to its melting point with a heat gun. Coupons were weighed a second time to determine the amount of buffing compound added. Three coupons were cleaned in each solution for five minutes using 40 kHz ultrasonic agitation. Coupons were rinsed for 15 seconds in a tap water bath at 120 F and dried using a dry compressed air for 30 seconds. Once dry coupons were weighed a final time and product efficiencies were calculated.
Trial Results:
Both products were very successful with the increased temperature and the use of ultrasonic energy. The table lists the amount of buffing compound added, the amount remaining, and the efficiency of each coupon cleaned.
| Cleaner | Initial wt | Final wt | % Removed |
| Daraclean 283 | 0.1812 | 0.0005 | 99.72 |
| 0.1230 | 0.0007 | 99.43 | |
| 0.1115 | 0.0019 | 98.30 | |
| Polyspray Jet 790 XS | 0.3844 | 0.0145 | 96.23 |
| 0.1155 | 0.0010 | 99.13 | |
| 0.0962 | 0.0010 | 98.96 |
Success Rating:
A follow up test, usually based on company input.Conclusion:
Both products will be used on the next supplied buffing compound.
