What is Molybdenum Disulfide MoS2 Powder ？ Molybdenum Disulfide，Chemical formula MoS2, melting point 2375, density 4.80g/cm3 (14), Mohs hardness 1.0 ~ 1.5.Decomposition begins at 1370℃and is decomposed into metals molybdenum and sulfur at 1600℃. When 315℃ is heated in the air, it begins to be oxidized, the temperature rises, and the oxidation reaction is accelerated. Molybdenum disulfide contains a significant amount of active sulfur which can easily cause corrosion of copper. This is covered in a variety of publications and articles on additives to lubricants.In addition, when the parts of copper and its alloys need to be lubricated, molybdenum disulfide lubrication products cannot be used but also need to add anti-corrosion copper agents. Functions of Molybdenum Disulfide MoS2 Powder: Molybdenum disulfide is an important solid lubricant suitable for high temperatures and pressure.It also has diamagnetic properties and could be used as an inverse photoconductor, as well as an electronic semiconductor showing P-type or N-type conductive properties, with rectification and energy exchange roles. Molybdenum disulfide may also be utilized as a catalyst dehydrogenating complex hydrocarbons. The main function of molybdenum disulfide used in friction materials is to reduce friction at low temperatures, increase friction at high temperatures, small firing loss, and be volatile in friction materials. 1. Anti-friction: Molybdenum disulfide formed by supersonic airflow grinding processing particle size of 325-2500 mesh, microparticle hardness 1-1.5, The friction coefficient ranges from 0.05-0.1 and can be utilized in friction materials and could play an important function in anti-friction.friction coefficient of 0.05-0.1, so it can be used in friction materials can play a role in anti-friction. 2. Increasing friction: Molybdenum disulfide is not conductive, and there are copolymers of molybdenum disulfide, molybdenum trisulfide, and molybdenum trioxide. When the friction material temperature rises quickly due to friction the molybdenum trioxide atoms in the copolymer expand in response to temperature.ise, which plays a role in increasing friction. 3. Anti-oxidation: molybdenum disulfide is obtained through a comprehensive reaction of chemical purification, and Its PH value is 7 somewhat alkaline. It is a protective coating on the friction material, and may shield other materials and prevent them from oxidizing, especially so that other materials are not easy to fall off and the adhesion is enhanced. Molybdenum Disulfide First Aid Measures: Inhalation: Remove from site to fresh air. Seek medical attention. Eye contact:Pull up the the eyelids and wash using saline or water. Seek medical attention. Skin contact: Clean up contaminated clothing and rinse using running water. Ingestion:Drink a sufficient amount of warm water to cause vomiting. Seek medical attention. Molybdenum Disulfide Emergency Treatment: Isolate the contaminated area of leakage and restrict access. Cut off the fire. It is highly recommended to wear dust-masks for emergency workers (full faces masks) and protective clothing. Avoid dust; sweep it up carefully, place it in a bag, and transfer it to a safe place. Suppose there is a large amount of leakage with a plastic sheet or canvas cover. Collect and recycle or transport to waste disposal site for disposal.
Advantages and Disadvantages of Molybdenum Disulfide: 1. Eliminate oil leakage, clean, and greatly promote civilized production. 2. Can save a lot of lubrication grease. 3. Improve the operation technology, extend the maintenance period, reduce the labor intensity of maintenance workers, and save the labor force. 4. Molybdenum disulfide has the characteristics of moisture-proof, water-proof, alkali-proof, and acid-proof. 5. Molybdenum disulfide also has shortcomings, such as poor thermal conductivity, a friction coefficient is not low enough, permeability is not strong (compared to thin oil), and so on. The shortcomings of solid lubrication are problems in progress, and these problems can be overcome through repeated practice and continuous improvement and creation for our hard-working, brave, and intelligent Chinese people who can make progress. Molybdenum disulfide solid lubricating base is a new lubricating material that conforms to "more, faster, better, and less" and should be vigorously promoted and applied.
