Description

Electroplating bath solution comprehensive management device

Technical Field

The invention belongs to purification equipment, and particularly relates to a comprehensive management device for electroplating bath solution.

Background

Electroplating: the electroplating technology, namely electrodeposition, is to plate a thin layer of other metals or alloys on the surface of some metal materials by utilizing the principle of electrolysis. The electroplating process is a surface processing method in which under the action of DC electric field, a loop is formed by anode and cathode in the salt solution (Ni, Cr solution) containing the metal to be plated, and the metal ions in the solution are deposited on the surface of cathode plating part by utilizing electrolysis action to make the surface of metal or other material product adhere a layer of metal film.

Electroplating management tank: the electroplating process is generally provided with an electroplating bath and a management tank, wherein the management tank aims to ensure that bath solution is always in a circulating state, adjust the liquid level of the electroplating bath and ensure that the concentrations of main salt, conductive salt and the like in each part of the bath solution are uniform. The change of the concentration of each ion in the plating solution can directly affect the electroplating effect, and the Cr of the solution in the plating tank can be changed along with the electroplating process³⁺And chromic anhydride, and the like, and in order to ensure that the concentration of each ion is in a specified range, supplements such as chromic anhydride, a catalyst, sulfuric acid and the like need to be added, but if a large amount of supplements are directly added into the plating bath, the stability of the plating layer of the running product is influenced. Therefore, the plating tank is usually connected to a buffer-operated control tank, and the both are always in an uninterrupted circulating state, thereby ensuring that the concentration of the plating solution is always within a predetermined range.

Sulfate radical: cr (chromium) component³⁺Is an important component of the adhesive film, SO₄ ^2-The coating has high content, is easy to dissolve, leads to slow deposition speed, is difficult to form or is thin and porous, has large exposed matrix area and poor coating uniformity, and has no chromium layer in a low current density area, thereby influencing the anti-corrosion capability of the coating; SO (SO)₄ ^2-When the content is low, the glue film is compact, the sulfuric acid is difficult to dissolve, the chromium layer can only grow on the original crystal grains, the crystal is rough, the plating layer is dark and dull, and the plating layer is rough.

The content of sulfate radical has great influence on the electroplating process, and SO in bath solution₄ ^2-When the content is high, unpurified sulfate ions can affect the electroplating efficiency and the plating effect. The over-high concentration of sulfate radical in the hard chromium electroplating bath solution can cause Cr³⁺The deposition speed is slowed down, so that the plating time is increased under the same time and the plating efficiency is influencedAnd the low current density area has no chromium layer. Therefore, the concentration of sulfate group needs to be adjusted to a predetermined range. According to the traditional treatment technology, only the titanium net is placed in the management tank and contains a certain amount of barium carbonate, so that the generated barium sulfate is deposited at the bottom of the tank body, the method for purifying and recycling the titanium net can not effectively reduce the concentration of sulfate radicals, only the titanium net is placed in the tank liquor, the tank liquor can not be fully contacted with the barium carbonate in the titanium net, the purification area is limited, the purification efficiency is low, and the barium carbonate needs to be repeatedly added for many times. Meanwhile, waste residues are deposited at the bottom of the tank body and are not easy to clean, and a production line cannot normally operate, so that economic benefits are influenced.
