Molybdenum Disulfide MoS2 For Lubrication
Oil futures tumbled more than $5 a barrel on news that the Biden administration is considering releasing about 1 million barrels a day from the U.S. Strategic Petroleum Reserve (SPR) for several months to cool surging crude prices.
Brent crude futures were down $4.71, or 4.2 percent, at $108.58 a barrel by 0035 GMT. U.S. West Texas Intermediate futures fell $5.45, or 5 percent, to $102.74 a barrel.
At an earlier time, gasoline prices had already reached record levels because of the Russia-Ukraine conflict.
The prices of other commodities like the MoS2 powder are also expected to be volatile.
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.

Inflationary pressures on Canadians continue to rise. The consumer-price index rose 6.7% in March from a year earlier, the biggest increase since January 1991, according to the latest figures from Statistics Canada.
On a month-on-month basis, Canada's CPI rose 1.4 percent in March, also accelerating from February's 1.0 percent rise.
Prices in the eight major sectors covered by the statistics continued to rise. The uptrend comes against the backdrop of continued price pressures in the Canadian housing market, widespread supply chain constraints, and geopolitical conflicts, according to CBC. A variety of factors have affected energy, commodity, and agricultural markets. Meanwhile, Canada's employment picture continued to improve in March, with the unemployment rate falling to a record low and the average hourly earnings of employees rising.
Excluding gasoline, Canada's CPI rose 5.5 percent year on year in March. It is also the highest since comparable data began in 1999.
The widespread supply chain constraints and geopolitical conflicts are expected to continue to affect the prices of the MoS2 powder.
