Trial Purpose:
To evaluate client requested products on the first soil
Date Run:
07/08/2004Experiment Procedure:
Three cleaners were requested from the client. Six aqueous based cleaners were diluted to 5% using DI water in 600 ml beakers. All three products were heated to 120 F on a hot plate.
Nine preweighed titanium coupons were coated with client supplied tapping fluid, Castrol Industries Moly Dee Tapping fluid (63449-39-8, 64741-96-4), using a hand held swab and then weighed a second time to determine the amount of soil added. Three coupons were cleaned in each solution for 5 minutes using stir-bar agitation. Coupons were rinsed in tap water for 15 seconds at 120 F, followed by air blow off at room temperature. Once dry, coupons were weighed a final time and efficiencies for each cleaner were calculated.
Trial Results:
Two of the three products removed over 85%. The third product removed just under the 85%. The table below lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
| Cleaner | Initial wt | Final wt | % Removed |
| M Aero | 0.2398 | 0.0276 | 88.49 |
| 0.2288 | 0.0381 | 83.35 | |
| 0.3865 | 0.0562 | 85.46 | |
| M Aero NS | 0.2533 | 0.0440 | 82.63 |
| 0.2507 | 0.0011 | 99.56 | |
| 0.4063 | 0.0015 | 99.63 | |
| M 400 | 0.2437 | 0.0316 | 87.03 |
| 0.2773 | 0.0456 | 83.56 | |
| 0.2295 | 0.0376 | 83.62 |
Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
The three client requested products will be tested on the second supplied soil under the same operating conditions.
