Grease colors are more than justaesthetics; they serve a functional purpose. By using different colors, varioustypes of grease can be easily identified, minimizing the risk of using thewrong lubricant. This visual distinction is especially important in industrialapplications.

In maintenance, grease color can indicateits quality. Normally, grease retains a consistent color. However, when exposedto contaminants, oxidation, or mixed with other types of grease, it may darkenor change color. For example, contaminated grease can become darker, whiledegraded grease may lose its original color.

One of the common problems with grease inuse is drying out and hardening, which can affect equipment performance. Themain causes of grease drying out include:

• Contamination: Dust, dirt, or other     impurities entering the grease.

• Incompatibility: Mixing different     types of grease, which destroys the grease’s structure.

• High-Temperature Evaporation: Base     oil evaporates at high temperatures, causing the grease to harden.

• Oxidation: Base oil gradually     oxidizes, turning into a tar-like substance.

• Mechanical Overheating: Excessive     grease application or poor equipment operation raises temperature.

Dried grease can lead to severe issues. Itblocks lubrication channels, reduces lubrication effectiveness, increasesfriction, and even causes equipment failure. This is especially problematic incentralized lubrication systems, where dried grease can clog pumps andpipelines.

To prevent grease from drying out,selecting high-quality grease is essential. Yirunde's Qindao series offers awide range of grease colors, each representing different properties to meetvarious operating conditions. With this color-coded system, users can easilychoose the right grease, ensuring efficient lubrication and avoiding mistakes.
