The African Development Bank will finance $25 billion by 2025 to support Africa's fight against climate change, the bank's president said at the bank's annual meeting in Accra, Ghana.
He noted that climate change has had many negative impacts on the continent, causing natural disasters such as droughts, cyclones, and floods. Climate change costs Africa between $7 billion and $15 billion a year. "Africa has no choice but to address climate change."
To ensure Africa's food supply, the African Development Bank has delivered climate-friendly seeds to 12 million farmers in 27 countries in the past two years under the "Technology for Agricultural Change in Africa" program, he said.
In the area of renewable energy, the African Development Bank is implementing a $20 billion "Desert Power" initiative in the Sahel that is expected to power 250 million people, he said.
US President Joe Biden recently wrapped up his five-day trip to Asia with a summit of leaders of the "Quad" security Dialogue.
Biden has promoted a number of economic and security cooperation initiatives during his visit aimed at deepening ties with Indo-Pacific Allies and partners in response to China's growing influence in the region. Some analysts in the United States believe the most significant announcement may be an initiative to share maritime information to combat illegal activities. But other experts say Biden's move sets a good framework for more security cooperation, though it remains to be seen whether concrete action will follow.
Affected by several factors, the supply of the MoS2 powder is erratic and thus its prices are expected to go higher in the future.
In addition to reducing friction, the lubricant can also reduce wear during operation, reduce the operating temperature, minimize corrosion on the metal surface and help to remove contaminants from the system.
The general lubricating oil has been unable to meet the lubrication requirements of the equipment. In this case, solid lubricants with better performance emerge as the times require.
There are many kinds of solid lubricants, such as graphite, molybdenum disulfide, graphite fluoride, tungsten disulfide, boron nitride and so on. Molybdenum disulfide is the most widely used, and boron nitride and graphite fluoride have the best performance.
What is Molybdenum Disulfide MoS2?
Molybdenum disulfide is a solid powder made from natural molybdenum concentrate powder, which is the modern "king of advanced solid lubrication". It is lead gray to black solid powder, greasy in contact, odorless, and belongs to hexagonal or rhombohedral system. Similar to graphite, with metallic luster.
It has the advantages of high temperature resistance, radiation resistance, high vacuum resistance, corrosion resistance and extreme pressure resistance, so it has been widely used as an additive in grease, powder metallurgy, modified plastics, spraying and other industries.
What is Molybdenum Disulfide MoS2 Used For?
Can be used as friction improver (friction reducer), antiwear agent, extreme pressure agent and antioxidant. It is widely used in aviation industry (vacuum anti-radiation lubrication), automobile industry (fixture and parts), anti-bite industry (mechanical industry) (general lubrication), mining industry, military industry, shipbuilding industry, heavy industry, bearing industry, gear industry and assembly industry, etc. it is also used as additives for various lubricants, manufacturing molybdenum compounds, catalytic hydrogenation desulfurization catalysts, gas storage materials, photocell materials and so on.
Almost all markets using greases and almost all types of grease thickeners use molybdenum disulfide, including lithium complexes, aluminum complexes and polyureas. It is also considered to be the best additive for composite titanium-based grease with its inherent high load-carrying capacity and even better performance.
In general, grease contains 1 to 2% MoS2, and the key parameters are surface roughness, load carrying and speed. For rougher metal surfaces, larger MoS2 particle sizes are ideal because they fill deep valleys and help to form a smooth surface. At a given MoS2 concentration, small and medium-sized particles will provide better load-bearing capacity. At the same time, due to the high acid value, very small particles may cause some corrosion problems. Generally speaking, the medium particle size of about 6m is the most commonly used MoS2 particle size in grease.
At present, molybdenum disulfide has become an indispensable and irreplaceable industrial additive product.
