Molybdenum Disulfide MoS2 For Lubrication
Argentina's Rosario Grain Exchange recently reported that wheat MoS2 powder are expected to continue to be influenced by international situations.
Molybdenum disulfide (MoS2) is known as the "king of lubrication" and has its unique advantages in the field of lubrication. It has a layered structure and still maintains good lubrication performance under harsh conditions such as high temperature, high pressure, high rotation, ultra-low temperature and so on. Because of its low friction coefficient, MoS2 is a natural excellent solid lubricant. It also has excellent properties, such as natural weak alkalinity, excellent antioxidant capacity, used in the aviation field, can extend the mileage of engine oil.
MoS2 is a kind of black solid powder with metallic luster, its melting point is as high as 1185℃, and its chemical stability and thermal stability are good. In the metal, the Mohs hardness is low, which is 1.0-1.5. The initial temperature of decomposition is 1370℃. When it reaches 1600℃, it decomposes into metal molybdenum and sulfur. MoS2 is insoluble in many substances, such as water, dilute acid and concentrated sulfuric acid, nor in other acids, bases and organic solvents, but it will dissolve when it comes into contact with aqua regia and boiling concentrated sulfuric acid.
The basic material of molybdenum disulfide lubricant is made of ultra-fine MoS2. When the lubricant is applied to the metal surface, a dry film will be quickly formed on the metal surface, so that the surface of the metal parts can form a protective film, which can withstand high temperature, strong pressure, toughness, parts are not easy to wear, burn and bite.
Friction wear almost appear in a variety of industries, such as aerospace, automobiles and ships, mechanical heavy industry, bearing gears, etc. MoS2 can be widely used in many occasions of lubrication. For example:
1. Slides for cabinets or drawers, guide rails for elevators, bearings for motors, etc. Under high load, these parts are under great pressure and need lubricants to reduce friction and prolong service life.
2. In the process of material processing, in order to punch and punch the material, it is necessary to apply lubricant to minimize the friction between the die and the plate, produce a finished product that meets the requirements, and prevent the surface of the material from rusting.
3. When the temperature of the rear wheel increases while driving, it is easy to throw oil, which will lead to brake failure. The application of MoS2 to the four-wheel bearing of automobile chassis can improve the lubrication performance, save oil and reduce the temperature of the four wheels when driving.
4. In some extreme conditions, fasteners, threads, etc., are easy to slip teeth or bite to death during assembly, and need to be coated with lubricant to reduce friction, prevent parts from getting stuck, and prevent rust.

With Russia taking the lead on Poland and Bulgaria at the end of last month, there appears to be a growing sense of compromise within the EU over whether to accept Moscow's proposed rouble settlement order.
Italy's prime minister said recently that European companies would be able to buy gas in roubles without violating sanctions. This apparently ignores the guidance of hardliners in the EU to "fight to the end".
For weeks, European companies have been trying to find ways to meet Russia's payment demands for the rouble while maintaining vital gas supplies without violating sanctions against Moscow.
Late last month, European Commission President Von der Leyen said operating under the mechanism would violate sanctions and asked European companies not to bow to Russian demands. However, the EU has yet to issue more rigorous written guidelines on how companies should pay Gazprom.
The Italian prime minister said recently, "There is no official announcement from the European Union about what ruble settlement means for sanctions violations, and no one has said whether ruble payments violate sanctions or not. It's a grey area."
"In fact, most gas importers are already opening rouble accounts for deals with Gazprom,"
He also used German companies as a shield. He said Germany's largest gas importer had already paid in rubles. "In fact, we saw evidence yesterday that the largest gas importer in Germany has already paid in rubles."
