Benefits of technology

The technical effect of this patented technology lies within its ability to stick well on both surfaces without losing any liquid or other substances that may be harmful for them during use. It also prevents evaporation from liquids while still being effective at protecting things like paper. Additionally, there are no flammable chemicals involved making up an entire system.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the durability of wire roping that has been made from stainless steels (SS) over recent years without adding any extra materials like oil or water on top. Lubricants have traditionally had issues with sealing between different parts within the cable's interior when they were applied before installation onto its final destination. Therefore there needs an improved solution where better protection could occur through more complete coverage of the metal surfaces being worked upon while also allowing for easy maintenance after each usage period.

Embodiment 1

[0013] In terms of parts by weight, put 50 parts of base oil into the kettle, heat up to 130°C, add 5 parts of fatty acid calcium until it is completely melted, maintain the temperature of the material at about 130°C, and keep it for 20 minutes, then put in 10 parts of microcrystalline wax until it is completely dissolved. Keep it for 50 minutes, then add 2 parts of nano-silica, 1 part of oleic acid, 3 parts of alkyl diphenylamine, 1 part of barium petroleum sulfonate, and 2 parts of sodium metaborate to dissolve them all, and stir at this temperature for 55 minutes , the temperature is naturally lowered to below 90°C, and the kettle can be taken out to obtain the grease composition.

Embodiment 2

[0015] In terms of parts by weight, put 60 parts of base oil into the kettle, heat up to 130°C, put in 7 parts of fatty acid sodium until it is completely melted, maintain the temperature of the material at about 130°C, keep it for 25 minutes, and then put in 20 parts of microcrystalline wax until it is completely dissolved. Keep it for 50 minutes, then add 4 parts of nano-silica, 1 part of oleic acid, 4 parts of alkyl diphenylamine, 1 part of barium petroleum sulfonate, and 2 parts of potassium metaborate to dissolve them all, and stir at this temperature for 50 minutes , the temperature is naturally lowered to below 90°C, and the kettle can be taken out to obtain the grease composition.

Embodiment 3

[0017] In terms of parts by weight, put 70 parts of base oil into the kettle, heat up to 140°C, add 9 parts of fatty acid sodium until it is completely melted, maintain the temperature of the material at about 140°C, and keep it for 20 minutes, then put in 30 parts of microcrystalline wax until it is completely dissolved. Keep it for 50 minutes, then add 6 parts of nano-silica, 1 part of oleic acid, 6 parts of alkyl diphenylamine, 1 part of barium petroleum sulfonate, and 5 parts of potassium metaborate to dissolve them all, and stir at this temperature for 50 minutes , the temperature is naturally lowered to below 90°C, and the kettle can be taken out to obtain the grease composition.
