A wave of layoffs that has swept the entire Internet industry has intensified. China's Internet industry has experienced several crises and major changes in the past development process. There is also a "brief history of layoffs by major Internet companies". Hot search, JD.com has a wide range of layoffs in this round of layoffs, and all its subsidiaries are involved. Most of the layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also reported the news of downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou was reported to have laid off 30% of its staff, and the e-sports department of Station B laid off 90% of its staff.
Mass layoffs on the internet have created a host of socioeconomic issues, including copper powder.
About Copper Powder Cu Powder:
Since the application of metal copper is very wide, the consumption and production capacity in the metallurgy of toned metallurgy is second, second only to aluminum. The nano-copper powder is well thermally conductive, self-lubricity, and high activity, making it an important role in many areas, such as electrical, mechanics, chemistry, etc. This is derived from the unique basic characteristics of nano-copper powder: surface interfaces effect, quantum dimensional effect and quantum tunnel effect. Macroscopic, copper powder has a high activity, so oxidation occurs in air, soluble in thermal sulfuric acid and nitric acid. At present, copper nanoparticles are often used as catalysts, lubricants, conductive coatings, and is also widely used in engineering structural materials, aerospace and biological engineering.
Copper is a very durable and ductile metal that is widely used due to its thermal conductivity and conductivity. Copper metal powder can be used in wires or combined with other metals to form different alloys (such as copper, copper and copper). Bronze is formed in conjunction with tin. When exposed to air, the outer copper layer is slowly oxidized into black copper oxide. According to different conditions, it can also form copper carbonate, a green copper roof or copper coating.

Product performance of copper powder Cu powder:
Cu powder, CAS 7440-50-8 High purity, uniform particle size distribution, easy to disperse use.
How is Copper Powder Cu Powder produced?
At present, there are many methods for preparing nano-copper powder, which can be divided into physical law and chemical methods.
Preparation of copper powder in physics method has the following methods:
The atomization method is mainly to break the metal copper liquid by high-speed airflow, thereby forming a fine droplet and then solidifying into a powder, which has become the main development trend of the current production of copper powder. The atomization method has the advantages of low production cost and small environmental pollution.
2. Mechanical ball mill
The mechanical ball milling method is widely used to prepare copper powder. The mechanism of action of the ball mill is mainly impacts collisions and rolling through metal balls, making it strong shaping deformation and constantly refining. The advantage of this method is that the process is simple, high yield, but is prone to impurities during the production process, and the powder size is not uniform.
3. Gas evaporation method
The mechanism of action of gas evaporation method is mainly to vaporize the metal copper or form a plasma in a lively atmosphere or an inert atmosphere, and then react with the lively atmosphere and cool the condensation, or by collision with the inert atmosphere, cool and condense, thereby forming a fine Copper powder. The copper powder prepared by this method has the advantages of controllable particle size, uniform shape, high purity, good crystallinity.
Preparation of copper powder by the chemical method:
The electrodeposition method is to make the copper ions in the cathode in an electrochemical mode to obtain a copper powder. This method is in an important role in the preparation of the metal powder. At present, the electrodeposition method of the metal powder has a DC method, pulse method, and composite total deposition method. Electrolysis is a method of achieving scale production. It is easy to optimize the morphology, particle size, and current efficiency of electrolytic copper powder by changing the electrolysis parameters.
2. Liquid phase reduction method
The liquid phase reduction method is currently the most widely used method for preparing metal nanomaterials. The principle is to reduce the metal cation in the solution under the action of the reducing agent to prepare microns or even nanoscale metal powder by controlling various process parameters. body.
3. Vapor deposition method
The vapor deposition method is a method for reacting one or more gases to precipitate the preparation of ultrafine powder by plasma, laser, or the like. A variety of powders such as metals, alloys, oxides, sulfides, and the like can be prepared by vapor deposition.
4. Sol-gel method
The sol-gel method is mainly by hydrolyzing the metal ionic organic compound or an inorganic compound to form a sol, and then dried, grind, and calcined after solidification, thereby producing a nanofin.

The day after the shooting at a Texas elementary school, the National Rifle Association issued a statement saying it "extends its deepest sympathies to the families and victims involved in this terrible and evil crime," adding it would "reflect on these events and pray for the victims."
It comes just days before the National Rifle Association's annual convention in Houston, Texas. Houston is less than five hours away. Texas Governor Tony Abbott, Senator Ted Cruz, and others are scheduled to attend the event, which has also caused a lot of controversies.
Texas Democratic gubernatorial candidate Mark O 'Rourke took to social media to call on Abbott to pull out of the convention, urging that it be held outside Texas. Many American netizens also took to social media to express their dissatisfaction. "I wish the NRA's annual meeting was held three days after 19 children and two adults were massacred," said one. "The school shooting was not a lone Wolf, but with the help of the NRA."
Between 2000 and 2020, US gun manufacturers produced more than 139 million guns for the civilian market, according to the Justice Department report. The NATIONAL Rifle Association (NRA) is one of the leading gun rights advocates with more than 5m members and deep pockets. The United States has not passed major gun control laws for more than two decades, blocked by gun interests.
The copper powder price is predicted to increase in the next few days.
