Factors that can affect the performance of extreme pressure lithium complex greases

The following are some factors that can affect the performance of extreme pressure lithium complex greases

Properties of the base oil

The viscosity, flash point, pour point, oxidation stability and other indicators of the base oil will directly affect the lubrication performance, low-temperature fluidity and high-temperature stability of the grease.

The content and structure of the thickener

The proportion of the thickener and its molecular structure determine the consistency, mechanical stability and colloidal stability of the grease.

The type and dosage of additives

Extreme pressure anti-wear agents, antioxidants, rust inhibitors, anti-corrosion agents, etc. The type and dosage will significantly affect the extreme pressure performance, antioxidant capacity, rust prevention and anti-corrosion of the grease. performance.

Temperature

High temperatures may cause oxidation and deterioration of the grease, volatilization of the base oil, and changes in consistency, thereby affecting its lubrication effect; at low temperatures, the grease may harden and have poor fluidity.

Load

Under high load conditions, the grease needs to have better extreme pressure and anti-wear properties, otherwise it may not be able to effectively protect the friction pair.

Speed

During high-speed operation, the grease may be thrown out due to centrifugal force, which affects the lubrication effect. At the same time, it requires higher shear resistance.

Moisture and impurities

Moisture will cause the grease to emulsify and deteriorate, and impurities may wear the friction surface and reduce the performance of the grease.

Storage conditions

Temperature, humidity, light, etc. Poor storage conditions may cause the grease to age and deteriorate prematurely.

Working environment

Dust, corrosive gas, etc. may contaminate the grease and affect its performance.

These factors interact to affect the performance of extreme pressure lithium complex greases. In practical applications, these factors need to be considered comprehensively to select and use the appropriate grease and ensure its full performance.
