Trial Number 1

Trial Purpose:

To reevaluate selected products using ultrasonics and higher temperatures.

Date Run:

08/17/2006

Experiment Procedure:

Three products from the previous trial were diluted to 5% in 250 ml beakers using DI water and heated to 130 F in a Branson 3510 ultrasonic tank and degassed for 5 minutes.
Nine preweighed coupons were coated with the red buffing compound using a hand held 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:

Two of the three products removed over 90% of the buffing compound within five minutes of cleaning at 150 F with ultrasonic energy. The table below lists the amount of buffing compound added, the amount remaining and the efficiency for each coupon cleaned.

Success Rating:

A follow up test, usually based on company input.

Conclusion:

The elevated temperature and ultrasonic energy improved the effectiveness  of both the Daraclean 283 and the Polyspray Jet 790 XS. These products will be tested on the supplied oil.
