Benefits of technology

The patent describes a way to improve the performance of lubricating systems by using hydrophilic fibers to remove water and other substances from the lubricant. These fibers can be in the form of a fabric material that is placed in contact with the lubricant. The hydrophilic fibers help to reduce corrosion and increase the service life of the lubricating system. The patent also mentions that the material used for the fibers can be made from a wide range of materials, allowing for flexibility in selection. Overall, the patent provides a technical solution for improving the performance and longevity of lubricating systems.

Problems solved by technology

The performance of known lubricating systems is negatively affected when water or other hydrophilic materials (fluids) are undesirably introduced into the system during the operation of a device that is being lubricated by the lubricating system.
Such undesirable aqueous materials can reduce the service life of the lubricant and / or can cause corrosion of the device.
Previous solutions for removing and / or eliminating water or other hydrophilic materials from the lubricating system have been inadequate.

embodiment 1

[0108]2. A grease , wherein the fibers comprise at least two portions having different physical and / or chemical properties.

embodiment 2

[0109]3. A grease , wherein at least one of the portions has a higher affinity to a like portion than to the oil and / or lubricating fluid, thereby imparting a self-assembly property to the thickening fibers.

[0110]4. A grease according to any preceding embodiment, wherein the fibers have a length of 100-500 microns.

embodiment 4

[0111]5. A grease , further comprising oleophilic thickening fibers having a length of 1-100 microns.

[0112]6. A grease according to any one of embodiments 1-3, wherein the fibers have a length of 1-100 microns.

[0113]7. A grease according to any preceding embodiment, wherein the fibers have a length that is at least about 5-10 times the diameter thereof.

[0114]8. A grease according to any preceding embodiment, wherein the thickening fibers are a mixture of organic fibers, e.g., polypropylene, and inorganic, e.g., ceramics, e.g., aluminum oxide and / or silicon dioxide.

[0115]9. A grease according to any preceding embodiment, wherein the fibers also have oleophobic and / or hydrophilic properties.

[0116]10. A grease according to any preceding embodiment, further comprising non-oleophilic fibers having oleophobic and / or hydrophilic and / or hygroscopic properties.

[0117]11. A grease according to any preceding embodiment, wherein the fibers are biodegradable.

[0118]12. A grease according to any pr...

Abstract

A hydrophilic composition for use with a lubricating system comprises hydrophilic fibers having a diameter between 50 nm and 10 microns and a length that is at least 5 times the diameter. The hydrophilic fibers having a strong affinity for at least one of water and other hydrophilic fluids and may remove or eliminate free or dissolved water in a lubricating system comprising at least one of an oil and a lubricating fluid.
