Project Number 1

Summary:

Several Aqueous cleaners were recommended for the removal of the preventive material and a terpene, T Square HTF 60, was suggested for the paint removal.

Test Objective:

Remove rust preventive coatings and prepare parts for assembly

Product Use:

Parts for large gear boxes, i.e. shafts, gears.
Trial Number Date Run Purpose Success Rating
0 07/08/1997 To determine a replacement for ink removal Test showed little or no promise.
1 07/09/1997 Four terpene based cleaners were tested Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
2 07/09/1997 Practical application of two terpene cleaners. A follow up test, usually based on company input.
3 07/25/1997 Non-hardening rust preventive cleaning trial. A follow up test, usually based on company input.
4 07/29/1997 Petroleum based rust preventative trial. Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
5 07/30/1997 Dirt, Grease, Oil, and metal fines cleaning. Test incomplete or inconclusive.
6 07/31/1997 Dirt, Grease, Oil and Metal Fines retest Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.

Project Number 2

Summary:

On-going project

Test Objective:

To replace hazardous cleaning solvent with a safer product.
Trial Number Date Run Purpose Success Rating
0 08/04/2008 To evaluate aqueous based alternatives for removing rust preventative coating using immersion cleaning. Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
1 08/04/2008 To reevaluate selected products on the first supplied rust preventative using higher concentrations Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
2 08/04/2008 To evaluate selected products on second supplied rust preventative using immersion cleaning at room temperature. Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
3 08/05/2008 To evaluate non-aqueous alternative cleaning products on the first supplied rust preventative Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
4 08/05/2008 To evaluate past products using ultrasonic cleaning on first supplied rust preventative Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
