Spraying equipment SPRAY EQUIPMENT
Plasma Spheroidization Spray Equipment and Its Technology for Producing Dense Spherical Powder
Characteristics of Plasma Spraying (1) It can spray a wide variety of coating materials, especially those with high melting points and refractory materials such as refractory metals, ceramics, metal-ceramics, and other special functional materials. (2) Inert gases can be selected as the working medium, reducing oxidative reactions of sprayed particles during their flight. (3) The coatings exhibit high bonding strength and low porosity; fine coatings can be prepared by precisely controlling process parameters.
Properties and Application Ranges of Four Common Ceramic Spraying Materials
Properties and Application Ranges of Four Common Ceramic Spraying Materials
Vacuum plasma spraying of titanium (Ti) and hydroxyapatite (HA) coatings; spraying titanium.
Combination strength analysis indicates that incorporating components such as metals or ceramics into the HA coating can improve the coating's bonding performance.
Plasma Spheroidization Powder Production Equipment
Using plasma as a heat source, refractory metals and ceramic powders are spheroidized and densified. The plasma arc temperature reaches over 15,000 degrees Celsius, causing the surface of the 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.
Imported plasma torches (torch for spraying ceramic powder materials such as alumina, chromia, and zirconia)
The imported SG100 plasma torch is an 80-kW multiphase torch suitable for a wide range of applications. Whether you’re engaged in high-volume production requiring high-quality, uniform, and repeatable coatings or in small-batch production that demands speed and flexibility, the SG100 offers unparalleled versatility.
Chromium oxide, yttrium oxide, and titanium oxide spraying equipment
Plasma spraying is a thermal spraying process that uses a plasma arc as the heat source and primarily employs spray powder materials.
Nickel-aluminum alloy plasma spraying on wire mesh to fabricate porous-structured Raney nickel wire mesh.
Nickel-aluminum alloy wire mesh is prepared by plasma spraying, resulting in a porous structure. Raney nickel—a fine-grained solid catalyst composed of a nickel-aluminum alloy—is widely used in numerous industrial processes. It was first introduced in 1962 by American engineer Murray Raney[1] as an alternative catalyst for the hydrogenation of vegetable oils in industrial production. Today, Raney nickel serves as a heterogeneous catalyst and is extensively employed in various organic syntheses and hydrogenation reactions. ●The preparation of Raney nickel involves reacting a nickel-aluminum alloy with sodium hydroxide. This process, known as "activation," dissolves most of the aluminum from the alloy, leaving behind a highly porous structure. This porous architecture provides an exceptionally large surface area, thereby endowing the catalyst with high catalytic activity. In a typical Raney nickel catalyst, nickel accounts for approximately 85% by mass; accordingly, for every two nickel atoms, there is one aluminum atom forming part of the catalyst. The aluminum plays a crucial role in maintaining the pore structure and thus contributes positively to the overall performance of the catalyst.
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.

Zirconia-yttrium spraying equipment, graphite boat plasma spraying production line equipment
The SX-80 heat exchanger, also known as a chiller or water cooler, is primarily used to cool distilled water that has been passed through a spray gun. After undergoing heat exchange via the refrigeration principle, the cooled distilled water—now at a lower temperature—is recirculated back into the spray gun, effectively cooling it and ensuring that the spray gun maintains an optimal operating temperature at all times, thereby extending the lifespan of the nozzle. The dual-compressor drive design reduces the overall size of the unit, freeing up more space for you.
Hydrogen Production Nickel Wire Mesh Coating Spraying Process, Plasma Spraying Equipment for Melting and Depositing Nickel-Rhenium and Nickel-Aluminum Alloy Coatings
Hydrogen production via water electrolysis 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, then reacts this alloy with a concentrated sodium hydroxide solution. As a result, most of the aluminum dissolves, leaving behind numerous micropores that give the nickel mesh surface a three-dimensional porous structure. This significantly increases the adsorption surface area, thereby boosting catalytic activity and improving hydrogen production efficiency. Guangzhou Sanxin provides nickel mesh coating equipment, plasma spraying equipment, automated production lines, as well as comprehensive technical support.
