eLUBE molybdenum disulfide
Molybdenum disulfide jest nieorganicznym związkiem.
Black crystalline sulfide of molybdenum occurs as the mineral molybdenite. It is similar in appearance to graphite, którrym is often confused. Molybdenum disulfide grease effect, which is a consequence of its structure. Atomic structure consists of a sheet of molybdenum atoms are placed between sheets of atoms of sulfur. Bonding between atoms molybdenum disulphide are strong, but the interaction between the sulfur atoms on the top and bottom in separate layers are weak, resulting in an easy-to-slip.

Production of molybdenum disulphide
Molybdenite ore is processed by flotation giving relatively clean MoS 2, where the main pollution is carbon. Molybdenum disulfide is formed also by heat treatment virtually all molybdenum compounds with hydrogen sulphide.
Use as a lubricant
Molybdenum disulfide particles in the size range between 1-100 micrometers is often used as a dry lubricant. It is often a component of blends and composites where low friction is desirable. Molybdenum disulfide occurs in many oils and lubricants as greases with its addition of retain lubrication even in cases almost total loss of oil, and thus are used in critical applications, such as aircraft engines. When added to plastics, molybdenum disulfide is a composite with improved strength, as well as reduced friction. Polymers that have been filled with molybdenum disulphide is nylon and teflon and Vespel.
MOS-2 is often used in two-stroke engines, for example. motorcycle engines.
Used in petrochemistry
Synthetic molybdenum disulfide is used as a catalyst for desulfurization in refineries, for example. hydrodesulphurisation of. The efficacy of MoS 2 as catalyst increases dodawając small amounts of cobalt or nickel and a mixture of the main based on aluminium oxide.
Rules for the application of:
MoS2 is a powder to do suspension and add to the oil
best powder spread in oil (to add to a new bottle and zamieszac, then pour into the engine)
to the engine an average 2-5 g/1 litre of oil,
to 10 g-20 g/1 litre
