According to a recent report from the Russian TASS News Agency, scientists at the Tomsk University of Technology in Russia have invented a method for rapidly preparing iron oxide nano powders. This powder can almost completely absorb electromagnetic radiation and can be used to process military equipment and eliminate electromagnetic interference.
According to experts from the School of Power Engineering at Tomsk University of Technology, iron oxide nanoparticles are synthesized in a very short time at a supersonic speed of several kilometers per second in an electric accelerator at a temperature of thousands of degrees. This nano-powder is widely used as an adsorbent for electromagnetic radiation, making "hidden bodies" undetectable by radar, or used to shield high-frequency electromagnetic radiation and electromagnetic interference. It can also be used as a coating for cable lines to reduce the loss of data packets during transmission.
According to reports, this iron oxide nanopowder is obtained from cheap raw materials (such as metal water pipes and gaseous oxygen) in milliseconds, and the research teams in Japan and the Czech Republic may take 1-3 days to complete this process, or even 1 Weeks. At present, scientists are studying the application of this material in fingerprint recognition.
Chrome Steel Grinding Media Balls
Steel ball is a commonly used grinding medium with the following characteristics:
1. High hardness: Grinding tool steel ball is usually made of high carbon chromium steel material, high hardness, can effectively grind hard materials.
2. Strong wear resistance: Due to the use of high hardness material, grinding tool steel ball has good wear resistance, can be used for a long time and is not easy to wear.
3. Good compression resistance: After special treatment, the steel ball of the grinding tool has high compression resistance, can withstand greater pressure, and is not easy to deformation or fracture.
4. Good grinding effect: The steel ball of the grinding tool has high grinding efficiency and grinding accuracy, which can quickly and evenly grind the surface of the object to achieve the required smoothness or accuracy.
5. Widely used: Grinding tool steel ball can be used for metal materials, ceramic materials, glass and other materials grinding processing, widely used in machining, electronic manufacturing, chemical industry and other fields.
It should be noted that the appropriate size and material need to be selected according to the specific situation during the use of the grinding tool steel ball to ensure the grinding effect and service life. In addition, pay attention to safety precautions during use to avoid damage to personnel and equipment
