Project Number 1

Summary:

Seven trials were conducted on the various supplied oils. There were three products, Aquavantage 1400, Inproclean 3800 and Sea Wash Blue, which were found to be successful on the five supplied oils. Next step would be to evaluate these products on actual parts. Additional work resulted in the company requesting a vapor degreasing drop-in solvent. Evaluations showed that nPB worked well. The company replaced 300-500 gallons of TCE usage on an annual basis. The switch over was completed in December of 2007.

Test Objective:

To replace TCE for cleaning lubricants from stamped parts. Investigating nPB but need more technical assistance.

Product Use:

Various uses
Trial Number Date Run Purpose Success Rating
0 08/14/2006 To evaluate possible alternatives to TCE for first supplied oil. Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
1 08/15/2006 To evaluate products on second supplied oil. Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
2 08/15/2006 To evaluate one product, successful on second soil, on first soil. A follow up test, usually based on company input.
3 08/15/2006 To evaluate successful cleaners on the third supplied oil using immersion cleaning. Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
4 08/21/2006 To evaluate the five previously tested products on the fourth supplied oil. Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
5 08/21/2006 To evaluate the three effective products on the fifth supplied oil. Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
6 08/21/2006 To evaluate three products on fifth oil using ultrasonic cleaning. A follow up test, usually based on company input.
7 06/12/2007 To evaluate selected products on the supplied parts using ultrasonic cleaning. Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.
8 07/09/2007 To clean supplied parts using drop-in vapor degreasing solvents. Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.
