To evaluate aqueous alternatives using ultrasonic energy on second supplied contaminant.
There are no related objects.
Six products from previous trials were selected for testing. Five of the products were diluted to 20% and the sixth product was diluted to 5%. Products were heated to 130 F and immersed in a Branson 40 kHz ultrasonic tank and degassed for at least five minutes.
Eighteen preweighed coupons were coated with the supplied rust preventative using a handheld swab and weighed a second time to determine the amount of soil added. Three coupons were cleaned with ultrasonic energy for five minutes, rinsed in tap water for 15 seconds at 120 F and dried using compressed air at room temperature for 30 seconds. Final weights were recorded, and efficiencies calculated for each coupon cleaned.
All six products removed more than 85% of the rust preventative, five of which removed more than 97%. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
