To evaluate successful products on second supplied contaminant using ultrasonics and heat.
Date Run:
09/23/2008
Experiment Procedure:
Eight products were selected from the previous trial based on success on removing the supplied soil. Five products were diluted to 5% using DI water in 400 ml beakers. The other three were used at full strength based on vendor recommendations. Beakers were immersed and heated to 130 F in a Branson 40 kHz ultrasonic tank. Solutions were degassed for five minutes.
Twenty-four preweighed steel coupons were coated with the rust preventative VCI 368 using a hand held swab. Coupons were weighed again to determine the amount of soil added. Three coupons were cleaned in each solution for 10 minutes using ultrasonic energy. Coupons were rinsed for 15 seconds in tap water at 120 F and dried using compressed air at room temperature for 30 seconds. Final weights were recorded and efficiencies calculated.
Trial Results:
Six of the eight products removed over 85% of the second supplied contaminant using heated ultrasonics. Five of these products removed over 90%. Kyzen's Ionox HC 2 and Chem Free Corp Ozzy Juice SW 1 were the two products that did not remove over 85%. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
