Description

Copper recovery system of electrolytic copper foil copper-containing flushing water

Technical Field

The utility model belongs to the technical field of copper foil production equipment, and relates to a copper recovery system of electrolytic copper foil copper-containing flushing water.

Background

Copper foil is a negative electrolyte material that is deposited as a thin, continuous metal foil on the substrate layer of a circuit board that serves as the electrical conductor for the PCB. It is easy to adhere to the insulating layer, receive the printing protective layer, form the circuit pattern after corroding.

The production process of the copper foil base material sequentially comprises the following processes: dissolving copper, filtering, adding additives, electroplating raw foil, and refluxing to dissolve copper, wherein the refluxing process is that raw materials overflowing after electroplating raw foil can be recycled, so that the raw materials are required to be refluxed into the copper dissolving pool for secondary circulating reaction.

The main component of the material in the reflux process is mixed liquor of solid Cu, copper sulfate and sulfuric acid, and the reflux is mainly used for refluxing the solid Cu and the sulfuric acid into the copper dissolving tank for secondary reaction. The applicant's experience shows that solid Cu in the mixture has a large particle state and a small particle state. Wherein, the large granular solid Cu needs to flow back to the copper dissolution pool for the second copper dissolution reaction, the dissolution process is slow because the large granular solid Cu has large volume, and the small granular solid Cu can be converted into free Cu after flowing back to the transportation channel after the copper dissolution directly and after a short time of dissolution process² ⁺. Therefore, the material is screened, the large granular solid Cu is separated and then sent to the copper dissolving pool, and the small granular solid Cu is separated and directly sent to the conveying channel, so that the yield can be improved more efficiently.
