Copper foil copper dissolving tank copper material arranging method

Abstract

The invention discloses a copper foil copper dissolving tank copper material arranging method. The method comprises the following steps: the copper material used in a copper dissolving tank comprisesrecycled large copper foil blocks, recycled small copper foil blocks, a copper wire coil and flattened copper plates; a plurality of layers of flattened copper plates are laid in the interior bottom of the copper dissolving tank, the copper wire coil is placed at the upper parts of the flattened copper plates, and then, the recycled small copper foil blocks are placed in gaps around the copper wire coil; and when the recycled small copper foil blocks are flattened to cover the flattened copper plates, the recycled large copper foil blocks are placed at the upper part of the copper wire coil. With adoption of the copper foil copper dissolving tank copper material arranging method, the copper material stacking density in the copper dissolving tank is increased, so that the loading volume ofthe copper dissolving tank is increased, the degree of uniformity of the air in the electrolyte is increased, the content of the impurity in the electrolyte is reduced, the dissolving speed of the copper material is increased, and energy consumption during the copper dissolving process is reduced to further improve the quality of the electrolyte while reducing the copper dissolving cost.

Description

technical field [0001] The invention relates to the technical field of electrolytic copper foil, in particular to a method for arranging copper material in a copper foil melting pot. Background technique [0002] The copper-dissolving process of electrolytic copper foil can be summarized as follows: the raw materials (including copper plate, copper wire, copper foil, etc.) evenly placed in the copper-dissolving container, under a certain temperature and wind pressure, are mixed with the sulfuric acid in the sulfuric acid solution inside the solution and the air. Oxygen in the chemical reaction process. [0003] The process of dissolving copper is the main preparation process of the electrolyte, and it is also the initial step in the production of electrolytic copper foil. The process of dissolving copper is mainly to provide pure electrolyte for the manufacture of raw foil. In the process of dissolving copper, the layout of the copper material is very important. Generally, ...

Problems solved by technology

[0004] In the actual production process, the raw materials used in the copper melting tank are mainly copper block, copper wire and copper foil. The conventional distribution method of the copper melting tank is as follows: figure 1 As shown, the four corners of the copper plate that are cut by a cutting machine will have high warpage. The copper wire placed in the middle of the copper melting tank will cause a small filling density due to the middle cavity and shape, and the recycling placed on the upper part Copper foil, due to the low bulk density, often has difficulty in filling. The above methods all lead to problems such as low bulk density, uneven distribution, and low output of copper material inside the copper tank, and even affect the quality of the electrolyte in severe cases.
