Trial Purpose:
To evaluate client requested cleaner on supplied contaminant
Date Run:
10/29/2002Experiment Procedure:
One client requested product was diluted to 3% (Liquinox) in 1500 ml beaker and the other was diluted to 5% in 400 ml beaker using DI water. The solutions were heated to 130 F on a hot plate. Six preweighed coupons were coated with Milacron Marketing Company CIMTECH® 310 metal working fluid concentrate (102-71-6, 78-96-6, 26896-20-8) using a hand held swab. Coupons were then reweighed using a Denver Instruments A250 balance to determine the amount of contaminant added. The coupons were immersed into each solution and cleaned for 5 minutes using stir bar agitation. Coupons were rinsed for 15 seconds in a tap water bath at 120 F and finally dried using a Master Appliance Hot Air gun at 500 F for 30 seconds. After the coupons were dried, final weights were recorded and efficiencies calculated for each cleaning solution.
Trial Results:
The Det-O-Jet cleaner was more effective than the Liquinox solution. The table below lists the amount of contaminant applied and remaining as well as the product efficiency.
| Cleaner | Initial wt | Final wt | % Removed |
| Liquinox | 0.1857 | 0.0438 | 76.41 |
| 0.4069 | 0.0428 | 89.48 | |
| 0.1169 | 0.0437 | 62.62 | |
| Det-O-Jet | 0.1841 | 0.02 | 89.14 |
| 0.2441 | 0.0225 | 90.78 | |
| 0.1244 | 0.0131 | 89.47 |
Success Rating:
A follow up test, usually based on company input.Conclusion:
Having been successful in removing the metal working fluid, Det-O-Jet will be evaluated on supplied parts using ultrasonic cleaning and OSEE analysis.
