Non-Bleeding Grease
Grease is affected by factors such as shear stress, load, vibration, high temperature, centrifugal force, and the material of the friction pair surface. This leads to the separation and diffusion of the base oil from the thickener, contaminating other components. Furthermore, this oil separation rapidly reduces the lifespan of the grease and causes it to become thicker and drier, losing its lubricating properties.
The main reason for oil separation during grease use is a decrease in colloidal stability. Colloidal stability is the ability of grease to maintain a stable colloidal structure under certain temperatures and pressures, preventing the lubricating oil from separating from the grease. Three main factors affect the colloidal stability of grease: the grease formulation, the manufacturing process, and the operating conditions.
When selecting a non-spreading grease, the following criteria should generally be considered:
- If the structure allows, choose a high-viscosity base oil or a high-hardness grease.
- Select products that use complex lithium, complex calcium, or lithium-based thickener
- The grease should contain additives to prevent oil separation and pass high-temperature diffusion tests.
- It should have anti-corrosion and rust-preventive properties and be compatible with most metals, plastics, rubber, and contact media.
Applications
Used for structural lubrication and noise reduction in electronics, automobiles, and precision instruments where grease contamination is unacceptable. Suitable for lubricating automotive control panel buttons, computer keyboards, and other products with strict requirements regarding oil separation. Also used for lubricating and dampening friction in measuring instruments, optical instruments, cameras, and other devices, specifically for lens focusing threads, guide rails, shafts, and areas around lenses, while also preventing oil leakage.
Non-Bleeding Grease
Contains special anti-diffusion inhibitors. Suitable for applications requiring no grease migration or contamination, such as computer keyboards, car control panel buttons, cameras, and precision instruments.
