Electrodeposition electrolytic nickel negative plate

Abstract

The invention provides an electrodeposition electrolytic nickel negative plate, which comprises a conductive beam and a negative plate, wherein the conductive beam is welded with the negative plate and has a core-spun structure in which a copper rod is wrapped by stainless steel; the stainless steel is removed from the two ends of the conductive beam to expose the copper rod; the negative plate is made of the stainless steel; a partition angle of 50 to 75 DEG is formed at the bottom of the negative plate; the negative plate has the thickness of 2 to 5 millimeters and the surface roughness of 6 to 30 micrometers; and an attached groove with the width of 5.8 to 8.5 millimeters and the depth of 0.35 to 0.5 millimeter is formed on the surface of the negative plate. In the invention, the conductive beam has the core-spun structure in which the copper rod is wrapped by the stainless steel, so that higher conductivity is ensured, the rigidity of the whole conductive beam can be ensured, and the conductive beam is difficult to bend; due to the roughness of the stainless steel negative plate, the sufficient combination degree between a nickel layer and the negative plate during growth of the nickel layer is ensured, so that bonding force is uniformly distributed, and the nickel layer is difficult to fall; and the stripping convenience of the nickel layer after the production of nickel is ensured, so that a nickel refining production process is optimized, production efficiency is improved, and product quality is improved.

Description

technical field [0001] The invention relates to an electrode for producing nickel, in particular to a cathode plate for electrowinning and electrolytic nickel. Background technique [0002] At present, when nickel is produced, nickel starter is generally used for production, but the production process of nickel starter is relatively complicated and labor-intensive. The mother plate in the production process is a titanium seed plate, and about 0.8 to 1.2 The nickel layer (skin) of mm, the nickel skin is manually peeled off and then sent to the initial electrode sheet processing process. After flat pressing, shearing, nailing, and embossing processes, it is made into a nickel initial electrode sheet of a specified size. The nickel initial electrode sheet after processing is qualified. The pole pieces are sent to the job site or designated area by forklift for stacking. The starter sheets transported to the site are manually threaded into rods, put on the shelves, and produced...

Problems solved by technology

[0003] To sum up, the production process of the starter sheet is cumbersome, the investment in personnel and equipment is large, and the labor production intensity is high, which fundamentally restricts the further improvement of the quality of electro-nickel.
