Trial Number 1

Trial Purpose:

To evaluate products from previous trial using ultrasonic cleaning equipment

Date Run:


Experiment Procedure:

Four products from the previous trial were diluted to 5% using DI water in 600 ml beakers and heated to 130F in a Crest 40 kHz ultrasonic tank. The four products were degassed for 10 minutes in the ultrasonic tank.

Twelve preweighed CDA260 brass coupons were contaminated with the Matchless Metal Polishing Company K55-278 Liquid Tripoli buffing compound (1317-85-8) using a hand held swab. Coupons were allowed to sit over night and reweighed to determine the amount of soil added. Three coupons were cleaned in each product for 5 minutes using ultrasonic energy. Coupons were rinsed in tap water for 15 seconds at 120F and dried using air blow off for 30 seconds at 68F. Once the coupons were dry, final weights were recorded and efficiencies were calculated.

Trial Results:

Two of the products removed over 85% of the buffing compound using ultrasonic energy. The other two products removed under 70% with the addition of the mechanical energy. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
