Problems solved by technology

In order to reduce the manufacturing cost of the pole plate, people try to reduce the thickness of the pole plate to reduce the material cost, which makes the pole plate easy to deform
At the same time, in actual production, in order to increase the production scale, the size of the plates is gradually increased. At present, most of the plates used by most enterprises have an overall size of more than 1000 mm. Due to the increase in the area of ​​the plates, the actual deformation of the plates Increase
In addition, during the electrolytic production process, due to the action of the electromagnetic field and the stress of the electrolytic deposit, the plate is prone to secondary stress deformation
Due to the deformation of the cathode and anode in the actual production process, the short circuit between the cathode and the anode increases during the electrolysis process. The light one will cause the current efficiency to decrease, and the severe one will cause the electrolysis process to be interrupted.
In order to solve the problem of plate deformation, most enterprises currently adopt the method of increasing the thickness of the plate to enhance the rigidity of the plate, but this method not only increases the manufacturing cost of the plate, but also cannot completely solve the problem of plate deformation
Therefore, in actual production, most enterprises have to arrange more operators to frequently check and deal with the short circuit between cathode and anode during the electrolysis process, which not only increases production costs, but also has poor results

Embodiment 1

[0023] Embodiment 1: The method for improving the flatness of the plate surface of the reticulated titanium-plated lead dioxide anode: this embossed and leveled electrolytic plate that enhances rigidity mainly includes a pole plate 1, and the surface of the pole plate 1 is provided with Several embossing grooves 2 form a concave-convex pattern. The insoluble anode plate is made of a titanium mesh plate, the thickness of which is 1mm to 3mm. First, the mesh plate is cut according to a certain size, and then the stripes are pressed by a flat press. The embossing groove 2 is composed of a plurality of horizontal The embossed grooves and oblique embossed grooves form a Pozi-shaped structure, and a protruding structure consisting of upper triangular bumps 3 and lower triangular bumps 4 is formed on the pole plate 1 . The depth of the pressed stripes is 2.5mm, and the stripes on the entire board surface are continuous stripes. After pressing, the surface of the board is flat, and t...
