What are the causes of extreme pressure lithium lubricating grease black? In fact, the result of lubricating grease is not caused by the result. There are many reasons for this result. I will introduce it to you today. Interested friends come to see together.
1. Black extreme pressure lithium lubricating grease means that it has been oxidized and deteriorated. If it is just the surface, the oxidation area can be removed, and it can still be used as usual. If you turn red, it means that the oil is still alkaline; if the color does not change, it means that the oil becomes acidic. Generally speaking, lubricating fat cannot be used for expensive equipment to avoid corrosion, but it can reduce standard use and use it for corrosive rough equipment. 2. The film formation of extreme pressure lubrication grease is also due to the oxidation reaction of lubricating fat, especially the lubricating fat made of dry vegetable oil, which is easy to occur. The processing method is the same as the above. 3. Oil collection indicates that the stability of the colloid has been destroyed. Slightly pumping oil can remove surface oil, and most of the rest are still available; but try not to use it at high temperature and high loads. Serious fuel -consuming products should not be used. 4. When the oil is absorbed or penetrated into the rain, it is easy to emulsify. Mild emulsification can still be used after removing the deterioration part.
5. If the lithium lubrication becomes thinner, it may be caused by the high storage temperature. If the concentration cannot be recovered, the pH value may be changed, and then it is no longer used.
6. One of the reasons for long -term freezing and oil sclerosis is long -term freezing. It can be stored for a period of time when the room temperature is slightly higher (such as 30-40 ° C) to restore the original state. The above phenomenon must be paid to the above phenomenon during use. Only by ensuring the quality of lubricating fat can it effectively extend its service life and achieve better use effects.
