Trial Purpose:
To evaluate Crystal Simple Green at 10% solution for different time frames.
Date Run:
02/15/2022Experiment Procedure:
The pre-soiled parts were weighed for dirty weights. The Crystal Simple Green was heated to 140 F and placed in the ultrasonics tank. The parts were then placed in the ultrasonics tank for 15 minutes, 10 minutes, and 5 minutes, one part for each timeframe. The coupons were taken out and left to dry; once the coupons were dry the clean weights were taken. After clean weights, the coupons were wiped down and weighed for initial weights. Visual observations were also noted.
Trial Results:
Crystal Simple Green at a 10% concentration works at all three timeframes. At 15 minutes the coupons were completely clean. At 10 minutes the coupons were clean with minor spotting left on the surface, could have been from pulling the coupon out and oil re-attaching. At 5 minutes the coupons were completely clean and did not have any spotting. All coupons had a 99% or higher removal average.
