Description

Technical Field

[0001] The utility model relates to the technical field of plasma spraying, in particular to an automatic spraying system for a hydrogen-producing nickel mesh electrode. Background Art

[0002] Nickel mesh is usually used when producing hydrogen by electrolysis. Nickel mesh is mainly used as the cathode in the process of electrolyzing water to produce hydrogen. Nickel has good conductivity, corrosion resistance and catalytic properties, and can effectively promote the hydrogen evolution reaction. In order to extend the service life of the nickel mesh, plasma spraying equipment is usually used to spray a coating (such as a nickel oxide layer) on the surface of the nickel mesh during production. Generally, the plasma spraying bed uses serrated steel bars to support the nickel mesh. When placing and removing the nickel mesh, scratches are easily generated between the nickel mesh and the serrated steel bars, which has a negative impact on the quality of the finished nickel mesh.

[0003] Based on this, an automated spraying system for hydrogen-producing nickel mesh electrodes is now available, which can eliminate the drawbacks of existing devices. Utility Model Content
