Validation of Alternatives to High Volatile Organic Compound Solvents Used in Aeronautical Antifriction Bearing Cleaning
Abstract
This demonstration and validation project evaluates a soybean oil derivative (SoyGold 1000) as an alternative to high VOC containing solvent for the rinsing of aeronautical antifriction bearings during DoD Depot level maintenance cleaning. Data analysis and interpretation are based on analytical test results as well as visual inspections performed on test bearings that were processed through the bearing cleaning process. Analytical test results are mixed. SG1000 passed all environmental, occupational, safety and health related tests, but failed a number of the materials compatibility tests including total immersion corrosion for a number of substrate materials, hydrogen embrittlement, nonvolatile residue, and nonvolatile residue with isopropyl alcohol rinse. SG1000 also failed the rinse efficiency test under performance related tests as well as the acidity test under chemical properties. Analytical test results did not meet the acceptance criteria to be qualified as an alternative to MIL-PRF-680 in the rinse step of the bearing cleaning process. During the demonstration, a nonvolatile residue resulted in a film that remained on the bearing surfaces. The demonstration results did not meet the defined acceptance criteria to be qualified as an alternative to MIL-PRF-680 in the rinse step of the bearing cleaning process. Overall SG1000 did not meet the acceptance criteria for analytical testing or the demonstration. SG1000 does not qualify as an alternative to MIL-PRF-680 in the bearing cleaning process.
