Trial Purpose:
To evaluate client supplied alternative cleaner
Date Run:
01/07/2002Experiment Procedure:
The supplied cleaner was diluted into two 600 ml beakers, both to 5% using DI water and heated to 130 F on a hot plate. One beaker was immersed into a Crest 40 kHz ultrasonic tank and degassed for 5 minutes. Six preweighed coupons were coated with the Fuch's Renocut 127 and allowed to sit for 1 hour. At the end of the hour, the coupons were weighed again to determine the amount of contaminant added to the coupons. Three coupons were immersed in each beaker and cleaned for 5 minutes, then rinsed with DI water at 120 F for 30 seconds and finally dried using a Master Chemical Heat Gun at 500 F for 1 minute. The coupons were weighed again and efficiencies were calculated.
Trial Results:
The ultrasonic cleaning appeared to rinse better the immersion cleaned coupons. The results for each coupon are listed in the following table.
Table 1. Cleaning Efficiencies
| Evercylce | Immersion | Ultrasonic |
| Coupon 1 | 97.79 | 99.99 |
| Coupon 2 | 94.86 | 99.44 |
| Coupon 3 | 96.15 | 99.87 |
| Average | 96.27 | 99.77 |
| Std Dev | 1.47 | 0.29 |
Both Immersion cleaning and the ultrasonic results were about the same as the results from the previous trials, as shown in the second table.
