1. Base oil: There are many kinds of mineral oil, synthetic oil, etc., with many viscosities and different colors, ranging from colorless to black.
2. Thickener: Lithium-based, composite lithium-based, calcium-based, composite calcium-based, etc., with different colors.
3. Additives: there are additives such as wear resistance, extreme pressure rust prevention, etc., from solid to liquid, with different colors
4. Solid additives: molybdenum disulfide, PTFE, boron nitride, etc., with different shades of color.
5. Dyeing agent: adding a specific dyeing agent, changing the primary color, distinguishing different product lines, easy to use.
6. The influence of the production process: the reasonable and normal deviation of the temperature during the production process, the color of the grease produced has a difference in density.
7. The influence of raw material batches: the color density may be different if the batch is different.
When it comes to the performance of grease, it is usually judged and selected based on the hardness, water resistance, extreme pressure resistance, wear resistance, and temperature range of the grease. If the performance parameters of a certain grease meet the specified requirements , It becomes a qualified product. It can be seen from the above that the performance of grease is not directly related to the color. A light color is not necessarily a good performance, and a dark color is not necessarily a poor performance.
As a user of lubricating grease, there is generally no conditions for analyzing the performance of the oil. It is not advisable to judge the quality of the oil only by observing the color and smell. Of course, users can also find uneven transparency, a large number of layers, and agglomeration of grease during use, and roughly judge whether the product is contaminated or outdated. It is best for users to choose professional and qualified lubrication product suppliers to jointly solve the problems faced by lubrication.
