Plasma spraying equipment, hydrogen-producing nickel mesh coating, electrolysis-based hydrogen production using nickel mesh coating—plasma spraying.

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.

SX-80 Plasma Spraying Equipment

Introduction to Plasma Spraying Technology
Plasma spraying is a thermal spraying process that uses a plasma arc as the heat source and primarily employs spray powder materials.

Steps of Plasma Spraying
During plasma spraying, a direct-current arc is generated between the cathode and the anode (nozzle). This arc heats and ionizes the introduced working gas, transforming it into a high-temperature plasma that is ejected from the nozzle, forming a plasma jet. Powder particles are fed into the plasma jet by a carrier gas, where they are melted, accelerated, and sprayed onto the substrate material to form a coating. The working gas can be argon, nitrogen, or a mixture of these gases with hydrogen added; alternatively, a mixed gas of argon and helium can also be used.

Characteristics of Plasma Spraying
(1) Capable of spraying a variety of coating materials, especially high-melting-point 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 to reduce oxidative reactions of spray particles during their flight.

(3) The coating exhibits high bonding strength and low porosity; fine coatings can be prepared by controlling process parameters.

SX-80 Plasma Coating Equipment

It was successfully developed based on the introduction and absorption of plasma spraying equipment such as the PT-A3000 and METCO-9M, and its overall equipment level is comparable to that of the METCO-9M. The equipment consists of the following systems: ① main power supply ② control cabinet ③ junction box ④ powder feeder ⑤ spray gun ⑥ heat exchanger and piping connections. The equipment’s key components and instruments all utilize products from well-known brands such as Schneider, Omron, and Chint, ensuring the equipment’s stability and high efficiency.

Equipment design operating environment:

Voltage: AC 380V ±10% Frequency: 50 Hz Temperature: -5 to 40℃ Relative humidity: 50-95%
