Plasma Spheroidization Powder Production Equipment

Plasma Spheroidization Powder-Making Equipment and Technology: Using plasma as a heat source, this technology spheroidizes and densifies refractory metal and ceramic powders. The plasma arc temperature exceeds 15,000 degrees Celsius, causing the surface of raw powder particles to melt rapidly. Under the action of surface tension, the powder undergoes rapid quenching, leading to particle shrinkage and spheroidization, ultimately forming dense, spherical powder particles. 1. The plasma reactor can be filled with inert gas, ensuring a pure and clean atmosphere that prevents oxidation. 2. The inner wall of the powder collection tank is equipped with a cooling water jacket, which prevents hot powder from adhering to the tank’s inner wall. 3. With a plasma arc temperature reaching 15,000 degrees Celsius, the powder cools rapidly in an inert atmosphere, resulting in fine particle size and excellent dispersibility. 4. The plasma equipment features a simple process flow and controllable gas supply, effectively preventing powder contamination and making it ideal for preparing high-purity powders. 5. The plasma spheroidization powder-making equipment includes: a powder collection tank, an exhaust gas filter, a plasma power supply, a control cabinet, a powder feeder, a transfer box, and a chiller; its power rating is 80 kilowatts. 6. The equipment processes between 2.8 and 10 kg of powder per hour via plasma arc treatment, and the powder feeder can deliver particles ranging from 5 to 200 micrometers in size.

Plasma-nickel mesh coating with zirconia for wear and corrosion resistance

Plasma-Nickel Mesh Coating with Zirconia Electrolysis of water for hydrogen production is currently an important industrial method for hydrogen generation. To enhance the adsorption surface area of nickel meshes, Guangzhou Sanxin Technology Development first coats the surface of the nickel mesh with a nickel-aluminum alloy. Subsequently, this nickel-aluminum alloy is reacted with a concentrated sodium hydroxide solution; most of the aluminum dissolves, leaving behind numerous micropores. As a result, the surface of the nickel mesh develops a three-dimensional porous structure, significantly increasing its adsorption surface area and thereby boosting catalytic activity and improving hydrogen-production efficiency. Guangzhou Sanxin provides nickel mesh coating equipment, plasma spraying equipment, and automated production lines, along with comprehensive technical support.
