Embodiment Construction

[0015] Example. A production process for ultrasonically dissolving copper in the production of electrolytic copper foil. The raw copper is placed in a copper dissolving tank filled with sulfuric acid solution. 2 ultrasonic generators, the power and frequency of the ultrasonic waves emitted by the ultrasonic generators are controlled at 1000~1500w and 20~100khz respectively. The ultrasonic waves vibrate the solution in the copper melting tank, and the ultrasonic waves vibrate the solution for the copper melting tank. Heat, the working temperature of the copper melting tank is controlled at 45-60°C, so that the copper sulfate produced by the reaction of the raw copper and the sulfuric acid solution is quickly peeled off from the surface of the raw copper to achieve the dissolution of the raw copper.

[0016] The working temperature is controlled by the thermocouple in the copper melting tank to prevent the water vapor and acid gas from volatilizing too quickly due to the high te...

Abstract

The invention discloses a production process for ultrasonic dissolved copper in electrolytic copper foil production. A copper raw material is placed in a dissolved copper tank filled with sulfuric acid solution. The process is characterized by comprising the following steps of: providing oxygen for the dissolved copper tank through an air delivery pipe, and simultaneously starting an ultrasonic generator on the dissolved copper tank, wherein the ultrasonic waves generated by the ultrasonic generator enables the solution in the dissolved copper tank to vibrate and provides heat for the dissolved copper tank when the solution vibrates, so that the copper sulfate generated by reaction of the copper raw material and the sulfuric acid solution is quickly peeled from the surface of the copper raw material and dissolution of the copper raw material is achieved. The energy consumption is low, the energy is saved, the production cost is reduced, and the copper dissolution rate can be greatly improved.

Description

technical field [0001] The invention relates to a production process of dissolving copper, in particular to a production process of ultrasonically dissolving copper in the production of electrolytic copper foil. Background technique [0002] The copper dissolving process is also called electrolyte preparation, which is the first process in the production of electrolytic copper foil. The purpose is to dissolve the copper material into a sulfate solution to supply the original foil production process. The chemical reaction formula of copper dissolving process is as follows: Cu+1 / 2 O 2 +H 2 SO 4 =Cu 2+ +SO 4 2- +H 2 O+221KJ [0003] At present, in the copper melting process of electrolytic copper foil, steam is generally used to provide heat for the copper melting tank under normal pressure to dissolve copper. ℃ below) these two kinds. The high-temperature copper-dissolving method has a fast copper-dissolving rate, but consumes a lot of energy, and the low-temperature ...
