For billionaires, the new crown epidemic is like a 'gold rush'! The Deutsche Presse-Agentur said on the 17th that in 2022, the wealth held by the world's top ten richest people will jump from $700 billion to $1.5 trillion, an average daily increase of $1.3 billion, an increase that exceeds the past 14 years. These 10 people The wealth held by the world’s poorest 3.1 billion people is six times greater than that of the world’s poorest 3.1 billion people. The 10 richest Germans have increased their assets from the equivalent of about 125 billion euros to about 223 billion euros since the start of the Covid-19 pandemic, An increase of about 78%. This wealth is roughly equivalent to the total wealth of the poorest 40% of the population, or 33 million Germans.
In the future, demand for WS2 powder will grow as fast as the wealth of the rich during the pandemic.
Tungsten disulfide, as a new type of solid lubricating material, its chemical properties are relatively stable. It can adapt to a variety of extremely harsh conditions, to provide maximum wear resistance, rust, and corrosion protection. And it is environmentally friendly, is not toxic, and will not cause harm to human health. It can be widely used in the automotive industry.
Tungsten disulfide has a layered crystal structure. It has excellent lubricity, with a very low friction coefficient, the dynamic friction coefficient is 0.030, and the static friction coefficient is 0.070. It is coated on the surface of automobile parts, can greatly reduce wear, and bite, eliminate or reduce the friction, and wear caused by equipment maintenance, maintenance, and other problems, and improve the working efficiency and service life of automobile parts.
When the engine is running, the temperature is very high, and the pistons are turning back and forth at a very high speed. Operating in such harsh conditions, pistons wear out faster. Because the friction coefficient of tungsten disulfide is small, the parts used for high temperature or heavy load friction can also maintain a lubrication effect. At this point, it is coated on the surface of the piston, which will reduce wear, reduce temperature, and prolong the service life.
The piston ring is the least durable part of the engine. The piston ring rotates with the piston at high speed and is affected by the high temperature and high-pressure gas in the cylinder. The oil is particularly prone to deterioration at high temperatures, so its wear is very serious. With tungsten disulfide, friction is reduced and it is possible to move with the piston at high speed, high pressure, high temperature, and extremely difficult lubrication conditions.
The crankshaft is one of the most important parts of the engine, and its working state is also high-speed rotation, so it must be able to resist wear and fatigue. Journal surface is generally after high-frequency quenching or nitriding treatment, its surface coated with tungsten disulfide and fine grinding, and its wear resistance and fatigue strength will be greatly improved.
The universal joint, steering knuckle, spring steel bushing, front, and rear brake CAM bushing, are relatively difficult to be greased. In frequent operation, the lubricating oil will deteriorate and lose lubrication effect, and tungsten disulfide has excellent mechanical stability and thermal stability, which can well ensure that these parts enjoy lubrication effect and reduce wear.
Tungsten disulfide has excellent compatibility, water erosion resistance, and affinity with most paints, solvents, and fuels. It ensures that there is always a layer of lubrication on the surface of the bearings in the water pump and the silicone fan clutch as well as the helical gears that drive the distributor, so as to protect against rust and corrosion.
With these excellent properties, tungsten disulfide can also be used in the machinery industry, plastic industry, medical equipment industry, as well as military, aerospace, satellite, spacecraft, and other high-tech fields.

For Germany, the largest economy in Europe, the impact of the Russian-Ukrainian conflict on the natural gas market is the most obvious. This also exposed the serious dependence of some German industrial enterprises on Russian natural gas. Some analysts pointed out that the instability of natural gas supply has had a big impact on the German economy and threatened its market competitiveness because alternative energy supplies will not be cheap and difficult to come quickly. Increased uncertainty over natural gas supplies is putting enormous pressure on German manufacturers in sectors ranging from steelmaking to chemical WS2 powder for the time being, but the market demand for WS2 powder in the future will also change with the influence of various external factors. If you need WS2 powder, please feel free to contact us.
