Lubrication lubrication illustrated black silica gel silica gel has been degenerating

Modern lubrication silica gel, to improve their lubricating properties are added the right amount of various additives. Add a detergent-dispersant lubricating internal combustion machinery used silica gel in the dark is normal shortly after, can not be considered "silica gel has been degenerating," easily replaced; add a lubricant additive bearing surface of silica gel often make changes in the course of black, which is normal. Therefore, we determined whether silica gel lubricant deterioration, it can not be judged solely on the visual, to conduct a comprehensive analysis. Conditional response to silica gel material when testing laboratory, to do according to the quality for silica gel.
