Product Introduction

Copper-coated molybdenum disulfide, chemical formula CuMoS2, it is a kind of coated metal powder with the same appearance of pure copper.

Copper-coated molybdenum disulfide is an important solid lubricant, it is especially suitable for high temperature and high pressure conditions. Due to low friction coefficient of molybdenum disulfide, the frictional resistance generated between the equipment is low, so it can save the power consumption. In addition, molybdenum disulfide has features of moisture and water proofing, alkaline resistance,proofing etc.. The plastic or powder with molybdenum disulfide can be made into all kinds of mechanical parts, this can save a lot of non-ferrous metals.The solid lubricant of copper-coated molybdenum disulfide is really a new type lubricant material accords with More-Fast-Better-Economizing.

Copper-coated molybdenum disulfide has the feature of diamagnetism, it can be used as linear photo-conductor or semi-conductor to show P type or N type conductivity, it has the function of rectification and transduction. Molybdenum disulfide can also be used as catalyst for dehydrogenation of complex hydrocarbon.

Copper-coated molybdenum disulfide is also be honored as The King of Advanced Solid Lubricant. Molybdenum disulfide is a kind of solid powder made from natural molybdenum concentrate powder after chemical purification and the change of molecular structure. The original color is black with a little bit silver gray, it has metallic luster and soapy feeling for touching,  insoluble in water. It has the advantages of good dispersibility and non-caking, it can be added into the grease to form non-cohesive colloidal state, this increase the lubricity and extreme pressure property. It is also suitable for the mechanical working condition of high temperature, high pressure, high running speed and high load, so it can extend the service life of the equipment. After being coated by special techniques, copper-coated molybdenum disulfide also has the stability and lubricity of copper at the same time, it is absolutely a kind of good new material.

Application and Advantages

Copper-coated molybdenum disulfide used as friction materials is mainly for low temperature anti-friction and high temperature friction-increasing, it features anti-oxidation, small loss on ignition and easy volatile.

1. Anti-friction: The fineness of the copper-coated molybdenum disulfide processed by supersonic jet milling can reaches 325-500 mesh, micro-particle hardness 1-1.5, friction coefficient 0.05-0.1, so it can be used as friction material to reduce friction.

2. Friction-increasing: During usage, there is copolymer  of copper-coated MoS2, MoS3 and MoO3 . When the temperature of the friction material increases rapidly because of friction, the MoO3  powder of the copolymer will expand with the temperature, this plays a role of friction increasing.

3. Anti-oxidation:Copper-coated molybdenum disulfide is produced by chemical purification and intergrated reaction, its PH value is 7-8, slightly alkline. Copper-coated molybdenum disulfide covers the surface of the friction material to protect it from oxidation, and increase the affixing force to prevent detachment of the other materials.

Besides, copper-coated molybdenum disulfide can also be used as the new material to make transistor. Compared with graphene which both belong to two-dimensional material, molybdenum disulfide has energy band gap1.8eV, but graphene has no energy band gap, so possibly molybdenum disulfide will have wide application in nano-transistor. What is more, the electronic mobility of the mono-layer molybdenum disulfide transistor can reach about 500 cm^2/(V·s), and the current switching rate can reach 1×10^8.
