The effect of free acid and base on the quality of grease

Issuing time:2022-11-06 08:46Author:YIRUNDE GREASE

The influence of free acid and base on the quality of grease is very severe, which is often discussed. The anticorrosion of grease has been paid more and more attention and the requirements are higher and higher. If the production grease contains free acids, especially low molecular organic acids, or contains too much free alkali, it will cause corrosion of metal parts. This is not the most troublesome, if it affects the grease oil increase, it is not, in that case, the consistency of the grease becomes soft, the drop point decreases, thus affecting the quality. Therefore, we must test free acid, alkali (semi-finished alkali, finished alkali) in the production process, and control the quantity.

So, what are the reasons for the corrosion of grease?

The results show that the corrosion is caused by: first, excessive free alkali, free low molecular organic acid; Second, active sulfur and water in additives. These causes are bound to corrode mechanical components. So in the process of producing grease, we must firmly control the quality and production procedures. High quality grease will satisfy consumers.
