Trial Purpose:
To evaluate selected cleaner on parts contaminated with buffing compound.
Date Run:
07/16/2008Experiment Procedure:
Five products were diluted to 3% using DI water in a 1510 Branson 40 kHz ultrasonic tank and heated to 130 F. The products were degassed for five minutes.
A set of three soiled steel parts coated with buffing compound were immersed into the ultrasonic tank and cleaned for 5 minutes. Following cleaning, coupons were observed for cleanliness without a rinsing.
A second set of parts were cleaned at 160 F.
Trial Results:
All parts cleaned were equally cleaned after five minutes of cleaning at both temperatures. Some water spots were visible on all parts, but no buffing compound residue remained.
Success Rating:
Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.Conclusion:
Any of the five products could be used successfully to remove the buffing compound from the steel parts using ultrasonic cleaning.
