Project Number 1
Summary:
Part of a joint venture between EPA, TURI and RI DEM to reduce the use of TCE in the Providence, RI area, eight trials were run to identify a safer cleaning product to remove resin from manufacturing parts. Green Solutions Floor Stripper, Graffiti remover, Bio T Max, EZ Solv, Maxi Solv and Graffiti Remover SAC were all successful in laboratory evaluations. Having found products successful on the resin coating, the next step will be to evaluate these cleaners on supplied parts.Test Objective:
To replace TCE in epoxy cleaning from various equipment piecesProduct Use:
Mixing epoxy| Trial Number | Date Run | Purpose | Success Rating |
|---|---|---|---|
| 0 | 06/23/2008 | To evaluate selected products for resin cleaning. | Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. |
| 1 | 06/23/2008 | To evaluate semi-aqueous products for resin removal using immersion cleaning. | A follow up test, usually based on company input. |
| 2 | 06/23/2008 | To evaluate successful products for longer cleaning times on the resin. | Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended. |
| 3 | 06/24/2008 | To evaluate successful products at lower concentration | Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended. |
| 4 | 06/24/2008 | To evaluate dilutions at longer cleaning times | A follow up test, usually based on company input. |
| 5 | 06/25/2008 | To evaluate top seven products without rinsing or air blow off drying. | Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended. |
| 6 | 06/13/2008 | Conduct on-site assistance to replace nPB/TCE for cleaning process. | Technology Transfer. |
| 7 | 07/10/2008 | To evaluate different cleaning parameters for resin cleaning | A follow up test, usually based on company input. |
| 8 | 07/10/2008 | To evaluate different cleaning parameters for resin cleaning | A follow up test, usually based on company input. |
| 9 | 07/10/2008 | To evaluate different cleaning parameters for resin cleaning | A follow up test, usually based on company input. |
