Electrolytic copper electrode plate and manufacturing method thereof

Abstract

The invention belongs to the field of metallurgy, and particularly relates to an electrolytic copper electrode plate and a manufacturing method thereof. The electrolytic copper electrode plate comprises an electrode plate body and side strips, the side edges of the electrode plate body are provided with through holes, the side strips are insulated, the side strips cover side edge areas and holes of the electrode plate body, and the cross sections of the side strips are in semi-elliptical shapes; the side strips are more firmly connected to the electrode plate body, the service life is long, the phenomena of climbing and long fingernails of electrolytic copper are eliminated, and formed copper plates or copper sheets are regular in structure.

Description

technical field [0001] The invention belongs to the field of metallurgy, in particular to an electrode plate of electrolytic copper and a manufacturing method thereof. Background technique [0002] In the electrolytic copper field of non-ferrous metallurgy, the cathode plate and the anode plate are placed opposite each other in the electrolyte tank, the copper on the anode plate is gradually dissolved into the electrolyte, and the copper in the electrolyte is gradually deposited on the cathode plate. Commonly used cathode plates are generally copper plates or stainless steel plates. [0003] On the side edge of the cathode plate, there is generally a "tension rod type" insulating edge band, which is composed of a sealed insulating clamp and a tension rod, and one side of the sealed insulating clamp is provided with a U-shaped clamp for clamping the pole plate. The other side is equipped with an arc-shaped groove for assembling the tension rod. The size of the U-shaped groov...

Problems solved by technology

[0006] However, there are still some deficiencies: 1. During the extrusion process, the polar plate moves in a straight line at a constant speed relative to the discharge port of the side mold of the extruder. Because the polar plate with a certain thickness has holes, the plasticized insulating material has Some of them are directly cured on the surface of the polar plate, and some need to be solidified by filling the holes and gaps. At or near the opening of the polar plate, it will become a weak part where the insulating material and the polar plate are tightly bonded. 2. The phenomenon of "climbing" and "long fingernails" in the process of electrolytic copper is difficult to overcome
