Aluminium buyers in the US physical metal market have held off on new orders amid fears of a recession triggered by rising inflation and supply chain crises.
Spot aluminium trading on the market has been suspended in recent weeks, according to industry sources, as uncertainty has increased following the outbreak of the conflict between Russia and Ukraine. Even before the war, the aluminium market was suffering from long waiting times and weak demand.
For aluminium buyers, recent poor US economic data have been a big factor in delaying purchases. Data released last month showed that the ISM manufacturing PMI came in at 57.1 in March, below expectations of 59 and down from 58.6 in February, unexpectedly hitting the lowest reading since September 2020. This was mainly due to a slowdown in new orders and MoS2 powder are expected to increase in the future.
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.
