Description

Technical field [0001] The invention relates to the field of electrolyte analysis, in particular to an electrolyte automatic adjustment system and an adjustment method. Background technique [0002] Electrolytic copper foil has excellent electrical conductivity, thermal conductivity, a certain degree of extensibility, and tensile strength. It is widely used in circuit board conductive materials and lithium battery negative current collectors. The manufacturing principle of electrolytic copper foil is to dissolve copper wire in sulfuric acid , After multi-stage filtration, the copper sulfate solution is electrolyzed in the foil machine, so that the copper is deposited on the surface of the cathode roller to produce continuous foil, and then the surface treatment process or the anti-oxidation process is made. Therefore, the electrolyte concentration is copper One of the key indicators to be controlled in the foil manufacturing process. [0003] At present, the electrolyte concentrat...

[0004] 1. Since manual sampling and measurement require a certain amount of time, only the concentration of copper ions in the electrolyte at a certain point in time can be detected, and the concentration of copper ions in the electrolyte cannot be detected in real time, so the copper ion concentration adjusted according to the above detection results is also not accurate Accurate, unable to reflect the electrolyte concentration in a timely and accurate manner;
