Everyone is familiar with lubricating oil, but what about grease? How much do you know about grease? Like other materials, grease will gradually deteriorate over time. The speed and degree of deterioration depends on storage conditions and handling methods.
During storage, the properties of grease will change. The oil may oxidize, precipitate, change in appearance, absorb impurities, and become hard or thinner. The degree of change is affected by the following factors: storage time, storage temperature, and the nature of the oil itself.
Due to storage conditions, some greases will age, the oil will become hard/soft, and the consistency will change, causing changes in the consistency level. The longer the storage time, the more severe this change trend will be. From this perspective, it is necessary to avoid storing grease for too long.
Wuhan Lubricant Company recommends that if the factory time exceeds one year, the needle penetration (characterizing the consistency of the grease) of the oil should be tested to check whether the consistency level of the grease exceeds the range allowed by its normal level.
Another suggestion is that the storage and use of grease should follow the "first in, first out" principle. This requirement is very simple, that is, when using a certain oil product, the one that was stored earlier should be used up first. In addition, checking the batch number or production date of the oil product can distinguish which is new oil and which is old oil.
