What are the factors that affect the durability of lubricating grease?

Grease is a semi-solid lubricating material made from mineral oil (or synthetic lubricating oil) and thickener. It has multiple functions such as lubrication, sealing, filling gaps and rust prevention. The following are the main factors affecting its timeliness:

1. Packaging factors

Packaging has an important impact on the timeliness of grease:

• Packaging size: Due to the colloidal structure characteristics of grease, especially soap-based grease, it is easy to produce oil separation under the action of gravity. The larger the packaging container, the more obvious the pressure oil separation tendency
• Sealing performance:
  • Good sealing can prevent dust and moisture from mixing
  • It can effectively prevent oxygen intrusion and reduce the risk of oxidation and deterioration
  • It is recommended to choose appropriate packaging and avoid overly large packaging containers

2. Shelf life

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 the storage period must be inspected for quality indicators before use to ensure that they can be used only after they meet the requirements

3. Storage conditions

Correct storage methods are crucial to maintaining the quality of grease:

• • Temperature control:
    • Indoor storage temperature should be lower than 35℃
    • Outdoor storage requires the use of tarpaulins and protective covers to avoid sun and rain
  • Access management:
    • After access, the surface should be smoothed to avoid leaving holes
    • Reduce oil separation
    • It is recommended to establish a warehouse registration system and follow the first-in-first-out principle

4. Transportation and handling

Proper transportation and handling can extend the service life of grease:

• • • Handling requirements:
      • Handle with care to avoid falling due to weight
      • Use appropriate means of transportation, such as tricycles or cars
    • Placement method:
      • Should be placed vertically
      • Avoid placing it horizontally or upside down
      • Ensure that it is well sealed during transportation and take rainproof measures

5. Environmental and safety precautions

To ensure safe use and environmental protection:

• • • Waste oil treatment:
      • Do not directly discharge it into the ditch or pour it into the soil
      • Use special containers to collect
      • Hand it over to a qualified recycler for treatment
    • Personal protection:
      • Avoid direct contact with skin allergies
      • Replace oil-contaminated work clothes promptly
      • Use clean tools to wipe the skin to avoid infection risks

Summary

There are many factors that affect the timeliness of grease use, and it is necessary to strictly control each link from packaging, storage, transportation, etc. Through scientific management and use methods, the performance of grease can be maintained to the maximum extent, its service life can be extended, and safety and environmental protection can be ensured. When using grease, enterprises should establish a sound management system to ensure that each link is effectively controlled to obtain the best use effect.
