Trial Number 6

Trial Purpose:

To evaluate client requested products on supplied parts

Date Run:

11/12/2002

Experiment Procedure:

Two products were selected based on client request for cleaning supplied parts. Both was diluted to 5% using DI water in 1500 ml beakers and heated to 130 F on a hot plate. Each solution was degassed for 5 minutes in a Crest 40 kHz ultrasonic tank. OSEE readings for six supplied parts were recorded using a PET SQM 100. Multiple readings were made for each of the parts. Three parts were cleaned in each solution for 6 minutes using ultrasonic energy. Parts were rinsed in DI water at 120 F for 15 seconds followed by drying with a Master Appliance Heat Gun at 500 F for 30 seconds. Once dry parts were dry, OSEE readings were recorded. The parts were then visibly inspected and wiped with a white towel soaked with Acetone to determine cleanliness.

Contaminant: Milacron Marketing Company CIMTECH® 310 metal working fluid concentrate (102-71-6, 78-96-6, 26896-20-8)

Trial Results:

The parts cleaned during this trial did not show any signs of the black residue after wiping with acetone soaked towels and swabs. OSEE readings showed that Det O Jet performed slightly better than the Liquinox. Table 1 below lists the OSEE readings for all six parts cleaned.

When comparing the results from this trial with the two products evaluated previously, the Daraclean product resulted in the cleanest parts based on OSEE readings, followed by Det O Jet. Citranox and Liquinox resulted in similar cleaning effectiveness. Table 2 lists the results from both this trial and the trial conducted for Daraclean and Citranox.

Success Rating:

A follow up test, usually based on company input.

Conclusion:

Both products tested in this trial did remove the black coating that has been a problem for the client.  Det-O-Jet was more effective than the Liquinox.  When compared to the previous trial, Daraclean 282 was the most effective product evaluated thus far.
