Molybdenum is made up of molybdenum and disulfide. It is a gray-black solid powder. It has an odorless feel and slippery feeling. It falls under the hexagonal and orthorhombic groups, is very similar graphite-like in texture, and also has metallic luster.
Molybdenum sulfide is an important solid lubricant. It’s used in automotive, aerospace (vacuum ray lubrication), industry machinery (general and specific lubrication), the composites industry (parts preparation), metallurgy (powder oil lubrication), among others. It is used as an additive in various lubricants.
Application of molybdenum diulfide
MoS2 finds a lot of use in optoelectronic material, composite materials bioanalysis medical fields catalysts carbon industry machinery manufacturing engineering plastics. Molybdenum dioxide has excellent lubricating abilities under extremely high and low temperatures. Because it is a vital solid lubricant, this product is well-suited to working environments under extreme temperatures and high pressure. Experts are now focusing their attention on the MoS2 nanoparticle. The general, layered MoS2 structure is known for its excellent performance in resisting wear and loss.
Molybdenum sulfide, lubricating medium addition
MoS2 features a special, spherical structure that allows it to roll and be dispersed in the oil. As such, it is frequently used as an additive to large-scale lubrication. Jin Yufu was one of many Sichuan who injected molybdenum sulfur lubricant into lubricating oil. It greatly enhanced the lubrication quality. Not only does this ensure the stable and continuous operation of every equipment but it also has the effect of energy savings and emission reduction.
Hu Kunhong et al. We compared the tribological effects of MoS2 of different shapes. Hollow spherical MoS2 can enhance the antifriction/antiwear properties of base oil by applying low load at low speed. However, it is able to maintain good antifriction & antiwear performance even under very high load. Conclusion: It performs in extreme pressures, lubrication loss and other conditions better than conventional MoS2.
Ge Rongxi (et al.) resorted to the use of molybdenum disulfide oil as the wheel fit press-fit medium because of the abnormal axle pull. Experiments show that the nanoMoS2 material is very lubricating.
Prepare wear-resistant composite material with molybdenum sulfide Nano-material
Use of MoS2 in friction for wear-resistant resin composite materials is extremely wide. MoS2 development opened the door to greater potential in developing such materials. Wang Jun used rubber-plastic combination materials as the basis to include nano-MoS2 (or ordinary molybdenum) disulfide in the matrix. Wang Jun then created a class for water-lubricated rubber/plastic composite tail bearings by using such materials with various loads and speeds. It was also tested for wear properties and friction. According to the test results, the composite’s friction coefficient decreased with increased rotational speed. Then it remained stable. With constant speed, the friction of such raw materials declines as the load increases.
Molybdenum, or molybdenum, sulfide, is an excellent solid lubricant that is useful in automotive, aerospace, mechanical, electronic, and electronics. It provides excellent lubricity, even under very high temperatures. Metal wire drawing, weapons internal coating and similar uses are some of the main applications for powder lubrication. A lubrication layer or block is created by organic blending. It can be used for rolling and translational lubrication on large machines. You can add it to oil, greases Teflon, nylon or paraffin. An alternative market to molybdenum is the creation of anti-corrosion substances. Anaerobic Acid is stable, so it can provide protection from corrosion to towers and pipes in chemical and petroleum industry through spraying and film-forming technology. Molybdenum Disulfide will not absorb dirt or contaminate textiles, food, and other production products. It has similar characteristics to static and dynamic friction coefficients and is stable, without sticking or sliding. It can also serve as a nonferrous and permanent metal release agent or a forged lubricant.
A high-purity molybdenum dioxide is produced using chemical synthesis. The specific area of the disulfide has increased, as well as its adsorption ability and reactivity. It is used to make high-efficiency hydrogenation catalysts for the petroleum industry and gas storage materials. Because the energy band in the thin molybdenum layer matches that of light, it has potential to be utilized to produce photovoltaic material. Because the molybdenum is smaller in particle size, its adhesion properties and the coverage are greatly improved. Two-fold increase in the performance of anti-wearing, and antifriction.
