Lubricating grease, as a semi-solid lubricating material, is prepared from mineral oil (or synthetic lubricating oil) and thickeners, and has multiple functions such as lubrication, sealing, filling voids, and rust prevention. The following are the main factors that affect its timeliness of use:

1. Packaging factors
Packaging has a significant impact on the timeliness of lubricating grease:

Packaging size: Due to the colloidal structure characteristics of lubricating grease, especially soap based lubricating grease, it is prone to oil separation under the action of gravity. The larger the packaging container, the more obvious the trend of oil separation under pressure
Sealing performance: Good sealing performance can prevent dust and moisture from entering, effectively prevent oxygen from entering, and reduce the risk of oxidation and deterioration. It is recommended to choose appropriate packaging to avoid oversized packaging containers
2. Retention period
Under ideal storage conditions:

Unopened products can be stored for 3-5 years
Products that have been opened but not properly sealed may deteriorate within 10 years. Products that have exceeded their storage period must undergo quality index inspection before use to ensure they are qualified before use
3. Storage conditions
The correct storage method is crucial for maintaining the quality of lubricating grease:

Temperature control: The indoor storage temperature should be below 35 ℃, and outdoor storage should use tarpaulins and protective covers to avoid direct sunlight and rain
Access management: After use, the surface should be smoothed to avoid leaving voids and reduce oil separation. It is recommended to establish a storage registration system and follow the first in, first out principle

summarize
There are multiple factors that affect the timeliness of lubricating grease use, and strict control is required from various aspects such as packaging, storage, and transportation. Through scientific management and usage methods, the performance of lubricating grease can be maximally maintained, its service life can be extended, while ensuring safe use and environmental protection. Enterprises should establish a sound management system when using lubricating grease to ensure effective control of all aspects and achieve the best use effect.
