Trial Purpose:
To reevaluate successful products on second supplied contaminant using ultrasonic cleaning.
Date Run:
09/05/2006Experiment Procedure:
Five products from the previous were diluted to 5% in 250 ml beakers using DI water and immersed in a hot water bath at 130 and degassed for five minutes in a Branson 3510 ultrasonic unit.
Fifteen preweighed coupons were coated with the red buffing compound that was heated to melting so that a handheld swab could be used to spread the compound onto the coupons. 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:
All products showed increased effectiveness with the addition of ultrasonic energy. The Detergent 8 removed over 95% of the buffing compounds. MC 132 and Polyspray Jet 790 XS removed over 65% after five minutes of cleaning. The other two products still removed under 60% of the buffing compound. The following table lists the amount of buffing compound applied, the amount remaining and the efficiency for each coupon cleaned.

Success Rating:
A follow up test, usually based on company input.Conclusion:
The three products that removed over 65% of the buffing compound will be tested on the third supplied buffing compound. In addition, the Detergent 8 will be tested on the first supplied buffing compound.
