Trial Number 171

Trial Purpose:

Laboratory evaluations of alternative cleaning products

Date Run:

02/06/2002

Experiment Procedure:

Cleaning: 5 min. immersion cleaning with air sparger as a agitation medium at 120 F.
Rinsing : 1/2 min. manual with water at 120 F.
Drying :1 min. with heat gun at 500 F.
Contaminant:
1. Grease : keystone KSL-111.ELF Lubricant, Diester based Grease
2. Lubricant - ITW Devkon Safetap stick, grinding lubricant, contains TSRK 80100221-5000P, TSRK 80100221-5001P, TSRK 80100221-5002P

Success Rating:

Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.

Conclusion:

1st 3 evaluations are for comparing stirbar agitation with air sparger. It was found that first two evaluations, the results were almost comparable but in the third one ie. with Watson formula 7300, air sparger was more affective, about 12% more efficiency.
