Project Number 1
Summary:
Lab recommended aqueous cleaners, Oakite Inproclean 3800 and AW Chesterton KPC 820N, which were successful in the lab. Company selected a different chemistry which led to problems with etching. Currently working to replace TCE with aqueous productsTest Objective:
To replace TCE in cleaning parts to avoid violating MWRA discharge limits.| Trial Number | Date Run | Purpose | Success Rating |
|---|---|---|---|
| 0 | 06/01/1995 | Grace Daraclean 294xx vs 283 in removing wax | Test incomplete or inconclusive. |
| 1 | 06/01/1995 | Daraclean 294xx results | Test incomplete or inconclusive. |
| 2 | 06/06/1995 | Test effectiveness of ND -17 in removing wax | Test showed little or no promise. |
| 3 | 06/08/1995 | Testing of four cleaners for Plating Job Shop | Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. |
| 4 | 06/22/1995 | To evaluate cleaners for removal of oils | Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. |
| 5 | 07/06/1995 | Test out the two new Oakite products | Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. |
| 6 | 07/20/1995 | Evaluate four AW Chesterton products | Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. |
Project Number 2
Summary:
Envirosolutions Bio-T Max was very successful in the removal of wax from the various parts submitted to the lab for testing. All four parts have been sent back to the client for evaluation.Test Objective:
To rid use of TCEProduct Use:
Aerospace industry| Trial Number | Date Run | Purpose | Success Rating |
|---|---|---|---|
| 0 | 06/29/1999 | To find a replacement for TCE in wax removal from multiple substrates. | Test incomplete or inconclusive. |
| 1 | 06/29/1999 | To further evaluate the one cleaner capable of removing the wax from the previous trial. | A follow up test, usually based on company input. |
| 2 | 07/01/1999 | To clean client supplied parts using cleaner from previous trials. | Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended. |
