Trial Purpose:
To evaluate selected products on supplied parts using ultrasonic cleaning
Date Run:
02/02/2007Experiment Procedure:
Three products were selected from previous trial based on effectiveness. Each product was diluted to 5% using DI water in 600 ml beakers. Each solution was heated to 150 F in a Branson 3510 ultrasonic tanked filled with water. The solutions were degassed for 5 minutes.
Three stainless steel rings without lacquer finish but were coated with Jackonslea Grey Color 305 A (1344-28-1) were cleaned in each solution for 5 minutes using 40 kHz ultrasonic cleaning. Rings were rinsed for 15 seconds in 120 F tap water and dried using compressed air at room temperature for 30 seconds. If the rings were not completely clean after the initial 5 minutes, the rings would be cleaned for another 5 minutes. In addition, if the rings were not completely cleaned after 15 minutes, new concentrations would be tested (10 and 20%).
Trial Results:
The observations made for each product at the various times and concentrations are recorded in the table below.
| Product | Conc | Time | Observation |
| Det 8 | 5 | 5 | Not clean. Most clean of three products at 5% |
| 10 | Almost clean | ||
| 15 | Still not 100% clean | ||
| 10 | 15 | Looked nearly clean, about same as MC 580 | |
| 20 | 10 | All rings looked cleaned | |
| MC 580 | 5 | 5 | Not clean. About the same as 790 XS |
| 10 | Cleaner than Det 8 | ||
| 15 | Still not 100% clean | ||
| 10 | 15 | Looked nearly clean, about same as Det 8 | |
| 20 | 10 | All rings looked cleaned | |
| 790 XS | 5 | 5 | Not clean. About the same as MC 580 |
| 10 | About the same as Det 8 | ||
| 15 | Still not 100% clean | ||
| 10 | 15 | No 100% clean | |
| 20 | 10 | All rings looked cleaned |
Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
All three products worked well at a 20% concentration for 10 minutes at 150 F. Both Detergent 8 and MC 580 worked well at 10% concentration for 15 minutes at 150 F.
