Hydrogen production electrolyzer porous nickel mesh, plasma spraying equipment for melting and spraying Raney nickel, plasma spraying equipment.

Porous Nickel Mesh for Hydrogen Production Electrolyzers Plasma Spraying Equipment for Melting and Spraying Rhenium-Nickel Plasma spraying equipment 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. 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 adopts 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, automated production lines, as well as comprehensive technical support.

Hydrogen production electrolyzer porous nickel mesh

Plasma spraying equipment for melting and spraying Reney nickel Plasma spraying equipment

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 and creating a three-dimensional porous structure on the nickel mesh surface. This significantly increases the adsorption surface area, thereby boosting catalytic activity and improving hydrogen production efficiency. Guangzhou Sanxin offers nickel mesh coating equipment, plasma spraying equipment, automated production lines, as well as comprehensive technical support.

Quality requirements:

1. High-quality raw materials are used, with a nickel-to-aluminum mixing ratio of 8:2, a nickel purity of 99.5%, and an aluminum purity of 99.6%. (Raw material testing equipment available.) 2. Spraying waste is not allowed for reuse. (Waste recycling plan provided.) 3. Prior to spraying, sandblasting is performed to ensure strong adhesion of the coating. 4. Coating thickness and weight: 240 g/m²—300 g/m²; complete inspection records must be maintained. (Online inspection available.)

5. The coating must remain intact when the nickel mesh is bent to 120°. 6. The spray gun’s angle relative to the nickel mesh must be appropriately designed (ensuring that the equipment is adjustable) to guarantee uniform spraying and maximize the coated area on both the warp and weft threads. 7. Visual inspection: (a visual inspection system can be provided) A. On non-sprayed surfaces, there must be no signs of high-temperature discoloration; on the mesh surface, there must be no coating flaking or surface burn damage. B The mesh surface remains smooth and flat after spraying, with no overall deformation. <5mm。 C , uniform coating

Technical requirements:

1. The primary coating material is nickel mesh, 40 mesh, with a wire diameter of 0.19 mm and dimensions of 1850×1850 mm per sheet. The equipment is designed for a web width of 2.5 meters, and the weight per sheet is ≥2673 g. The main unit price is available in two options: reciprocating machine and robotic arm. 2. The cathode is coated on one side only; the coating material is Raney nickel (nickel-aluminum alloy powder). 3. We plan to procure a complete set of equipment (including sandblasting, cooling, and environmental protection systems) as a turnkey project. (Please provide an equipment list including brand, specifications, and prices.) 4. Reserve space for future upgrades and modifications to accommodate multi-product coating requirements.
