määrdeomaduste

Määrdeomadused refer to the properties of a substance that determine its effectiveness as a lubricant. These properties are crucial for reducing friction and wear between moving surfaces, thereby preventing damage and improving the efficiency of mechanical systems. Key properties include viscosity, which is the fluid's resistance to flow; extreme pressure (EP) characteristics, which describe the lubricant's ability to prevent scuffing and seizure under high loads; and thermal stability, indicating its resistance to degradation at high temperatures. Other important factors are oxidation resistance, preventing the formation of sludge and varnish, and demulsibility, the ability to separate from water. The selection of a lubricant with appropriate määrdeomadused depends on the specific application, considering factors like operating temperature, pressure, speed, and the materials of the surfaces in contact. Understanding and controlling these properties is essential for the proper functioning and longevity of machinery.
