Recently, covid 19 outbreak spreads in Shanghai, China. There are more than 25,000 new asymptomatic domestic infections every day. China is implementing a dynamic zero-out policy. A leading respiratory expert said the key to COVID-19 prevention and control is to minimize transmission and fatality rate. Omicron has a low case fatality rate but is highly transmissible and can still claim many lives in large outbreaks. "Total openness is not applicable in China. For China, we should keep to the dynamic zero-out and gradually open up."
However, "dynamic zero clearance" is not the pursuit of complete "zero infection". As the Novel Coronavirus has its own uniqueness and strong concealment, there may be no way to prevent the detection of cases at present, but rapid detection and prompt treatment must be carried out, as soon as one case is found, one case will be dealt with.
The situation in Shanghai is serious. As the financial center of China, Shanghai is a very important city, and the outbreak of the epidemic in Shanghai will put a great impact on China's economy. The current task is to contain the spread of the epidemic as soon as possible, to achieve social zero so that Shanghai's life and economy quickly return to normal.
As China plays an important role in the global supply chain, the outbreak will have a significant impact on the supply and prices of many Molybdenum Disulfide, Molybdenum Disulfide Overview, Molybdenum Disulfide Application, Molybdenum Disulfide Suppliers, Molybdenum Disulfide Price.
Overview of molybdenum disulfide
Molybdenum disulfide is an inorganic substance, the chemical formula MoS2, is the main component of molybdenite. Black solid powder with metallic luster, molybdenum disulfide is an inorganic substance, chemical formula MoS2, is the main component of molybdenum ore. Black solid powder with metallic luster and smooth feel.
Basic information of molybdenum disulfide
English name: Molybdenum
Disulfide CAS No.: 1317-33-5
Molybdenum Disulfide Molecular formula: MoS2
Molybdenum disulfide molar mass: 160.06
Molybdenum disulfide Appearance: black/lead gray solid
Molybdenum disulfide density (water) = 1): 4.8
Molybdenum disulfide melting point (℃): 1185
Solubility of molybdenum disulfide: decomposed in aqua regia, hot sulfuric acid and nitric acid, insoluble in dilute acid and water
Molybdenum Disulfide Hazardous Properties: The powder will burn at high temperatures and react violently with peroxides.
How is molybdenum disulfide MoS2 powder produced?
MoS2 occurs naturally in molybdenite (a crystalline mineral) or pyroxene (a rare low-temperature form of molybdenite). Molybdenite obtains relatively pure MoS2 by flotation. The main pollutant is carbon. MoS2 can also be produced by thermal treatment of almost all molybdenum compounds with hydrogen sulfide or elemental sulfur, and by metathesis of molybdenum pentachloride.
Application of molybdenum disulfide
Molybdenum disulfide is an important solid lubricant, especially suitable for high temperature and high pressure. It is also diamagnetic and can be used as linear photoconductors and semiconductors showing P-type or N-type conductivity, with rectification and energy conversion. Molybdenum disulfide can also be used as a catalyst for complex hydrocarbon dehydrogenation.
It is also known as the "King of Advanced Solid Lubricants". Molybdenum disulfide is a solid powder made of natural molybdenum concentrate after chemical purification and changing the molecular structure. This product is black, slightly silver-gray, with metallic luster, smooth to the touch, and insoluble in water. This product has the advantages of good dispersibility. Not sticky. It can be added to various greases to form a non-stick colloidal state, which can increase the lubricity and extreme pressure of the grease. It is also suitable for high temperature, high pressure, high speed and the main function of molybdenum disulfide used in friction materials is to reduce friction at low temperature, increase friction at high temperature, and small loss on ignition. Volatile in friction materials.
Friction reduction: The particle size of molybdenum disulfide processed by supersonic jet pulverization is 325-2500 mesh, the particle hardness is 1-1.5, and the friction coefficient is 0.05-0.1, which can reduce friction when used as friction material;
Increase friction: Molybdenum disulfide is non-conductive, and there are copolymers of molybdenum disulfide, molybdenum trisulfide and molybdenum trioxide. When the temperature of the friction material increases sharply due to friction, the molybdenum trioxide particles in the copolymer expand with the increase of temperature and increase the friction force;
Antioxidant: Molybdenum disulfide is obtained through chemical purification and comprehensive reaction. Its pH value is 7-8, and it is slightly alkaline. It covers the surface of the friction material, protects other materials, prevents them from being oxidized, especially makes other materials not easy to fall off and enhances adhesion.

The EU’s draft REPowerEU plan calls for an increase of 15TWh of rooftop PV capacity by 2022. The draft also calls for EU and national governments to take action this year to reduce the time required to obtain permits for rooftop PV installations to three months, and proposes that "all new buildings and existing buildings with an energy grade OF D or above should have rooftop PV installations by 2025".
In addition, the European Commission is likely to set a target for installed PV capacity of 300GW by 2025 and 500GW by 2030. Some members are more aggressive, with Austria, Belgium, Lithuania, Luxembourg, and Spain demanding a 1TW target for 2030.
The REPowerEU initiative, worth 195 billion euros, was proposed by the EU on March 8 to phase out member states' dependence on Russian fossil fuels by 2030. In a few days, the European Commission will present a package to implement the RePowerEU strategy.
As an important application scenario of distributed PV, rooftop PV is not limited to land, and the development conditions are relatively convenient.
Since the end of 2021, Spain, France, the Netherlands, and other countries have introduced policies and measures such as government subsidies, tax cuts, fee reductions, and accelerated grid-connection approval to encourage the development of distributed PV. Europe's potential for rooftop PV is huge and will continue to be an important growth pole for the industry, according to Wood Mackenzie.
