Molybdenum Disulfide grease is a solid, semi-fluid, fluid ester containing disulfide, suitable for textile, printing and dyeing, metallurgy, mining, etc. Molybdenum disulfide as a lubricant not only has a great role in industry, for all walks of life have a great role.
Molybdenum disulfide grease is mainly used to lubricate friction parts of machinery, such as bearings, gears, chains, transmission systems, etc., can provide long-term wear and rust protection. Molybdenum Disulfide grease is a solid, semi-fluid, fluid ester containing disulfide, suitable for textile, printing and dyeing, metallurgy, mining and other industries.
Introduction to the performance characteristics of molybdenum disulfide grease: lithium molybdenum disulfide grease resistance to extreme pressure and load are good, the appearance of gray to black gray uniform paste, with good lubricity, mechanical safety, water resistance and oxidation stability. Common molybdenum lithium disulfide grease is suitable for the working temperature in the range of -20℃ ~ 120℃ mining machinery, metallurgical machinery and equipment, mechanical and electrical equipment, transportation and other high temperature, heavy load of various large machinery and equipment lubrication. Molybdenum disulfide grease is made from PAO with low viscosity. Good anti-wear extreme pressure performance, can carry heavy load, so can reduce internal parts due to high pressure and impact load caused by various wear. Good noise reduction, sound cancellation, shock absorption, does not contain any harmful substances, to ensure the safety of the production environment. Excellent corrosion resistance and rust resistance, can avoid parts and air, water direct contact, prevent corrosion, rust.
The function of molybdenum disulfide, effectively improve the service life of products, good thermal stability, oxidation resistance, low evaporation during use, no loss, suitable for long-term lubrication. Strong adhesion, attached to the surface of the parts, to prevent detachment due to speed and vibration conditions. Compatible with most media, such as rubber, plastic, metal, etc., and good low temperature performance, starting torque and running torque is small, the applicable temperature is -40℃-180℃.
Molybdenum disulfide grease is mainly used to lubricate friction parts of machinery, such as bearings, gears, chains, transmission systems, etc., can provide long-term wear and rust protection.
However, the general molybdenum disulfide lubricant is not suitable for automobiles, generally used in heavy load and impact load rolling bearings, especially in slow or vibration motion parts, such as universal joints. If this grease is used on bearings running at high speed, there will be a “sliding” problem. Because the grease containing molybdenum will reduce the friction coefficient, the ball can not realize the full 360 degree rotation due to the reduction of friction, resulting in grinding spots, resulting in the lubrication failure of the rolling bearing, reducing the service life of the bearing. Therefore, the grease containing molybdenum disulfide can not be used for lubrication of vehicle hub bearings.
But it also has obvious disadvantages. First molybdenum dioxide is not suitable for high speed, light load, low temperature. The operating temperature shall not exceed 190 degrees. And molybdenum dioxide belongs to color pollution, safety and environmental protection is not enough. Strong attachment to black, not suitable for some of the color requirements of the industry, such as textile light industry.
