Description

technical field [0001] The invention relates to a copper-dissolving tank for copper foil production, more specifically, to a copper-dissolving tank for copper foil production with the function of stirring and shoveling materials. Background technique [0002] Copper foil is made of copper plus a certain proportion of other metals. Copper foil is a negative electrolytic material. It is a thin, continuous layer of metal foil deposited on the base layer of the circuit board. It serves as the conductor of the PCB. , it is easy to bond to the insulating layer, accept the printed protective layer, and form a circuit pattern after corrosion. Copper foil is mainly used in electromagnetic shielding and antistatic. Putting conductive copper foil on the substrate surface, combined with metal substrates, has excellent conductivity and provides electromagnetic shielding effects. It is one of the basic materials in the electronics industry. [0003] At present, in the preparation process...

AI Technical Summary

Problems solved by technology

[0003] At present, in the preparation process of electrolytic copper foil, it is necessary to add copper material to acid solution to prepare copper ion solution. Usually, bundles of copper coils are directly put into a copper-dissolving tank containing acid solution for dissolution, which makes it difficult to accumulate at the bottom. The dispersion is uniform, and then a large amount of copper material at the bottom of the copper melting tank cannot be reacted, resulting in a waste of raw materials. In order to improve the reaction efficiency of copper material and acid solution, in the prior art, copper powder is usually used as copper material before the reaction. Add it into the copper-dissolving tank for reaction, although the contact area between the copper material and the acid solution is increased to speed up the reaction of the copper material, but the copper powder is easy to accumulate at the bottom of the copper-dissolving tank after the copper powder is directly added, thereby affecting the complete reaction of the copper material
