Bulk-mechanical properties of mixtures of lubricating grease with water

1. The properties and structure of certain calcium, lithium, barium-aluminum, and silica gel greases that have been studied are not too sensitive to the addition of water. A slight decrease can be noted in the yield values and viscosity at above-freezing temperatures, with an increase in viscosity at below-freezing temperatures. 2. The addition of water has a strong influence on mechanical stability and sometimes on the viscosity at −15°C for the complex calcium grease Uniol-1, and on the structure and properties of the sodium-calcium grease 1–13. The addition of 5% water softens the 1–13 grease, but an increase in water concentration to 20% gives a very marked hardening of the grease.
