The King of Solid Lubricants Molybdenum Disulfide

Molybdenum disulfide is the main component of molybdenum ore. It is a lead gray to black solid powder. It has a slippery feel and is tasteless. It is hexagonal or orthorhombic, similar to graphite, and has a metallic luster.

Molybdenum disulfide is a very important solid lubricant used in the automotive industry (fixing agents and components), aerospace (vacuum radiation lubrication), industrial machinery (general lubrication), composite material industry (parts preparation), metallurgical industry (powder lubrication) )Wait. It is also used as additives for various lubricants, molybdenum compounds, catalytic hydrodesulfurization catalysts, gas storage materials, photovoltaic materials, etc.

Molybdenum disulfide as a lubricant additive

 Because MoS2 has a very special spherical structure, it can be rolled and dispersed in a lubricating medium, so it is often used as a lubricating additive for large-scale applications. Sichuanese such as Jin Yufu injected molybdenum disulfide lubricant into the lubricant, which greatly improved the lubrication level of the base oil. While ensuring the continuous and stable operation of each device, it also has the effect of energy saving and emission reduction.

Hu Kunhong et al. The tribological properties of different forms of MoS 2 particles were investigated. Under low load and low speed, hollow spherical MoS 2 (hollow spheres) and flake nano MoS 2 (nano flakes) can improve the anti-friction and anti-wear properties of the base oil. Under high load and high speed, the hollow ball still maintains good anti-friction and anti-wear properties. The conclusion is that it is different from conventional MoS 2 in terms of extreme pressure and lubrication loss.

Ge Rongxi et al., in view of the large amount of strain on the shaft during the press-fitting process of a certain type of wheel, through field practice, proposed the use of molybdenum disulfide lubricant as the lubricating medium for the installation of the wheel press, which completely solved the problem of abnormal shaft tension. Experiments have proved that the nano-MoS 2 material has excellent lubricating properties.

 Preparation of wear-resistant composite material from molybdenum disulfide nanomaterials

 For resin-based wear-resistant composite materials, its use in friction is extremely wide. As a result, the development of MoS 2 has brought a broader development potential for this material. Wang Jun and others took the rubber-plastic composite material as the matrix and added nano-MoS 2 and ordinary molybdenum disulfide to the matrix material, thereby developing a type of water-lubricated rubber-plastic composite tail bearing material: load and speed. The friction and wear properties were tested. The test results show that under the same load, the friction coefficient of the composite material gradually decreases with the increase of the speed, and finally maintains a stable state. Under the condition of constant speed, when the load increases, the friction coefficient of such materials will decrease: the friction coefficient of composite materials first decreases and then increases with the increase of molybdenum disulfide addition, and in terms of friction coefficient, this material It is lower than general composite materials. MoS 2 molybdenum improves the performance of the material in this respect.

Overview of MoS2 friction modifier molybdenum disulfide

The unique sandwich structure of molybdenum disulfide (MoS2) gives it excellent lubrication and catalysis properties, and has great potential in the fields of friction, lubrication and catalysis. Based on the lubrication mechanism of molybdenum disulfide, research on its surface modification is reviewed, including surface organic coating, precipitation reaction coating, intercalation modification, etc.; at the same time, the current application fields of molybdenum disulfide are summarized, such as Self-lubricating thin layer, intercalated battery, high lubricity coating, etc. Catalysts, etc., and look forward to its future research directions.

 Application of MoS2 friction modifier molybdenum disulfide

Molybdenum sulfide is used in aerospace, automobiles, machinery and electronic communications and is a good solid lubricant. It provides excellent lubricity for equipment under high temperature, low temperature, high load, high speed, chemical corrosion and modern ultra-vacuum conditions. Powder lubrication is mainly used for metal wire drawing, internal coating of weapons, etc. The plate is lubricated by organic mixing to form a lubricating plate or block for translation and rolling lubrication of large equipment. It is added to lubricating oil, grease, polytetrafluoroethylene, nylon, paraffin wax, and stearic acid to improve the lubrication effect and reduce friction, extend the lubrication cycle, reduce costs and improve working conditions. The preparation of anticorrosive materials provides a new market for molybdenum disulfide. In order to maintain the stability of anaerobic acid, it provides corrosion protection for pipelines and towers in the petroleum and chemical industries through film formation and spraying technology. Molybdenum disulfide will not absorb dust in a dusty environment, nor will it pollute textiles, food and other products in production. The solid lubricating material made of it has the characteristics of similar dynamic and static friction coefficients, stable operation, and will not stick or slip. It can also be used as a non-ferrous metal mold release agent and forging film lubricant.

The high-purity molybdenum disulfide produced by chemical synthesis has a larger specific surface area, a stronger adsorption capacity and a higher reaction activity, especially the catalytic hydrodesulfurization performance. Used to prepare high-efficiency hydrodesulfurization catalysts and gas storage materials in the petrochemical industry. The energy band of the thin molybdenum disulfide layer is close to 1.78 eV, which matches the light energy, and has broad application prospects in photovoltaic materials. As the particle size of molybdenum disulfide becomes smaller, the adhesion and coverage on the surface of the friction material are significantly improved. Anti-wear and anti-friction properties have been doubled.
