Greases

Lubricating grease is a solid to semisolid lubricant that results from dispersing a thickening agent in a liquid lubricant. It loses its structure under load or stress, thereby releasing the liquid lubricant, and regains its original solid to semi solid appearance after the stress, thereby releasing the liquid lubricant and regains its original solid –to semisolid appearance after the stress is removed.

Description

Lubricating grease is a solid to semisolid lubricant that results from dispersing a thickening agent in a liquid lubricant.

Greases consist of:-

  • A liquid phase that may or may not contain performance enhancing chemical or additives.
  • A solid phase that has either a network structure, such as metal salt or soap or is simply dispersed in oil as in the case of non-soap thickeners such as polyurea, modified clay and graphite.

Functions of Grease:-

  • Grease prevents entrance of corrosive contaminants and foreign materials.
  • Grease is easier to contain than oils
  • Grease hold solid lubricants in suspension. Finally ground solid lubricants such as molybdenum disulphide (MOS2) and graphite are mixed with grease high-temperature service or for extreme high-pressure applications.
  • Fluid Level Does not have to be controlled and monitored.
