Molybdenum disulfide (MoS2) is an important solid lubricant.
Molybdenum disulfide is a solid powder made from natural molybdenum concentrate powder after chemical purification. The color of the product is black with silvery gray, metallic luster, greasy feeling to the touch, insoluble in water. The product has the advantages of good dispersion and no sticking. It can be added to various oils to form a non-sticking colloidal state, increasing the lubricity and extreme pressure of the oil; it is also suitable for high temperature, high pressure, high speed, high speed The mechanical working state of the load prolongs the life of the equipment; the main function of molybdenum disulfide (MoS2) used in friction materials is to reduce friction at low temperature, increase friction at high temperature, and have a small loss on ignition.
Molybdenum disulfide is used as a good solid lubricant in a wide range of applications, and the following working conditions are applicable:
- Lubrication under wide temperature conditions: the application range of lubricating oil and grease is about 60°C to 350°C. The molybdenum disulfide (MoS2) solid lubricant can be applied to the working temperature range of ¬270°C to 1000°C.
- Lubrication under heavy load conditions: the oil film of general lubricating oil and grease can only bear relatively small loads. Once the load exceeds the limit value it can bear, the oil film will break and the friction surfaces will bite. The molybdenum disulfide solid lubricating film can withstand an average load of 108Pa.
- Lubrication under vacuum conditions: under high vacuum conditions, the general lubricating oil and grease are highly evaporative, which is easy to damage the vacuum environment and affect the working performance of other components. Molybdenum disulfide solid lubricating materials are generally used for lubrication.
- Lubrication under radiation conditions: Under radiation conditions, general liquid lubricants will polymerize or decompose and lose their lubricating properties. The radiation resistance of molybdenum disulfide solid lubricant is better.
- Lubrication of conductive sliding surfaces: friction of conductive sliding surfaces such as motor brushes, conductive sliders, solar collector rings and sliding electrical contacts on artificial satellites working in vacuum can be made of carbon graphite or metal Lubricated composite materials.
- Occasions with very harsh environmental conditions: occasions with harsh environments, such as transportation machinery, engineering machinery, metallurgical and steel industry institutions, mining machinery and other transmission parts working in harsh environments such as dust, sand, high temperature and humidity, can be used Molybdenum disulfide solid lubricant for lubrication.
- Occasions in corrosive environments: For example, transmission parts such as ship machinery and chemical machinery work in corrosive media such as water (steam), sea water, acid, alkali, and salt, and must withstand different degrees of chemical corrosion. The transmission parts working in this situation can be lubricated with molybdenum disulfide solid.
- Occasions with very clean environmental conditions: Molybdenum disulfide solid lubricants can be used for lubrication of transmission parts in electronics, textiles, food, medicine, papermaking, printing and other machinery to avoid pollution.
- Occasions that do not require maintenance: some transmission parts do not need maintenance, and some transmission parts need to reduce the number of maintenance in order to save costs. In these occasions, the use of molybdenum disulfide solid lubricants is both reasonable and convenient and can save money.
This product has higher purity of molybdenum disulfide, more regular crystal structure and larger crystal grains. At the same time, the content of non-lubricating solid impurities is lower, eliminating the negative impact or interference of other impurities on the lubricity of molybdenum disulfide, so that its performance can be fully exerted.
Applicable fields include: semiconductor industry, molybdenum disulfide target material, battery industry, carbon brush industry, molybdenum disulfide coating and other fields.
