Molybdenum disulfide (MoS2)
This solid lubricant is also known as “the king of solids lubricants.”
Molybdenum diulfide, or molybdenum powder, is made from molybdenum concentrate that has been chemically purified. The color is black, with a slight gray metallic luster. It’s slippery and not soluble in water. Molybdenum diulfide offers the benefits of being non-sticking and dispersible. It can also be added to greases in order to produce a non-sticky, colloidal state. This will increase the lubricity as well as the extreme pressure.
It is suitable for equipment that is subjected to high-temperature, pressure, speed, and load mechanical conditions. Molybdenum Disulfide has the ability to increase friction and reduce friction when used at low temperatures.
Molybdenum diulfide is used in a variety of ways as a good solid grease.
1. Lubrication in a wide temperature range: the range for lubricating grease and oil is approximately 60degC-350degC. Molybdenum disulfide is a solid lubricant that can be used in the temperature range from 270degC up to 1000degC.
2. Lubrication for heavy loads: The oil films of general lubricating ointments and greases are only capable of bearing relatively small load values. Once the load is exceeded, the oil film will rupture. The solid lubricating layer can support a load of 108Pa on average.
3. Lubrication for vacuum conditions. Under high vacuum, lubricating greases and oils are highly evaporative. They can easily damage vacuum environments and impact the performance of other parts. Generally, solid lubricating material containing molybdenum diulfide is used to lubricate.
4. Lubrication in radiation conditions. Under radiation conditions liquid lubricants may polymerize, decompose or lose their lubricating characteristics. Solid lubricants offer better radiation resistance.
5. Lubrication of conductive surface: The friction between conductive surfaces such as motor brush, conductive slides, solar collector rings or sliding electrical contacts of artificial satellites that work in vacuum can be made out of metal or carbon graphite.
6. Molybdenum disulfide is suitable for harsh environmental conditions. For example, transportation machinery, engineering equipment, metallurgical or steel industry institutions, mine machinery and other transmission components that are exposed to dust, sand and high temperatures and humidity.
7. Corrosive Environments: Ship machinery, chemical machinery, and other transmissions parts working with corrosive mediums such as seawater, water (steam), acid, alkali or salt must withstand different levels of chemical corrosion. Molybdenum Disulfide Solid can be used to lubricate the transmission parts that are working in such a situation.
8. The environment must be very clean. The transmission parts of the electronic, textile, food and medicine, paper and printing machines, as well as other machinery, need to remain free from contamination. Solid lubricants such MoS2 can help with this.
9. Maintenance is not required in all cases: Certain transmission components do not require maintenance. Other transmission parts may need less maintenance. MoS2 solid greases are convenient and economical in these cases.
