Trial Purpose:
To reevaluate products on supplied parts.
Date Run:
07/27/2004Experiment Procedure:
Five products that were found to be effective on all three soils were used at 120 F in a Crest Ultrasonic 40 KHz tank. Four products were used at 5% dilutions in 600 ml beakers and the fifth was used as received from the client in a 400 ml beaker. Each beaker was submersed in the tank filled with water at 120 F and degassed for 5 minutes.
The preweighed parts were contaminated with Castrol Rustilo 4163 (64742-46-7, 8002-74-2, 34590-94-8)and the weighed again. Five parts were cleaned in each product for five minutes with ultrasonic energy. The parts were rinsed in tap water at 120 F for 30 seconds and dried using air blow off at room temperature for 30 seconds. Parts were weighed a final time and efficiencies were calculated. Parts were then packaged and sent back to client to determine effectiveness.
Trial Results:
The five products appeared to remove all of the Rustilo. Only two parts with ball bearings had less than 95% removal with ultrasonics. The table below lists the initial soil weight, final weight and cleaning efficiency for each part cleaned.
