Description

Water-saving anolyte conductivity adjusting device

Technical Field

The utility model belongs to the technical field of electrophoresis anolyte treatment facility, concretely relates to water-saving anolyte conductivity adjusting device.

Background

Electrophoretic coating is a coating method in which particles of a pigment, a resin, or the like suspended in an electrophoretic fluid are directionally transferred by an applied electric field and deposited on a surface of a substrate, which is one of electrodes.

At present, cathode electrophoresis is a coating process generally adopted in automobile body manufacturing, and is a main means for prolonging the service life (corrosion resistance) of an automobile body.

In cathodic electrophoresis, paint particles suspended in a paint liquid are deposited on a workpiece as a cathode in an acidic solution in the form of cations in an electric field. At the same time as the paint solution is deposited onto the workpiece, the acid, which is the paint solution, is released in the form of anions, which lower the pH of the bath solution and increase the conductivity of the bath solution.

Along with the continuous running of the electrophoresis, the anode metal is continuously dissolved, and Fe & lt 2+ & gt ions are continuously separated out. In addition, impurity ions are continuously brought in from the workpiece before treatment, so that the conductivity of the paint liquid is continuously increased.

An anode diaphragm system method is commonly used to adjust the system conductivity, especially on a large cathode electrophoretic coating line. The working principle is as follows: between the polar tube and the exchange membrane, an anolyte is filled. When current flows through the coating through the pole tube to the coating liquid, the acid in the coating is separated out and penetrates the exchange membrane into the electrolyte. The electrolyte is continuously circulated by a pump to continuously flush the anode, and takes away organic acid and impurity ions to enter an anode liquid tank. And a conductivity meter is arranged in the polar liquid pipeline system, and when the conductivity value exceeds the standard, an electric signal is sent out to control the opening of the electromagnetic valve, and deionized water is injected and overflows to adjust the conductivity value of the bath solution. When the normal set value is reached, the signal disappears, the electromagnetic valve is closed, the deionized water stops feeding water, and the electrode liquid stops overflowing. This device has supplemented a large amount of deionized water when adjusting the cell liquor conductivity value, and the direct overflow of deionized water that these regulations were used discharges and can produce a large amount of waste water, has not only increased deionized water use and processing cost by a wide margin, has also caused a large amount of water waste, and moreover, the waste water contains material such as a large amount of organic acids, metal ion, hetero ion and has also increaseed the processing degree of difficulty and the processing cost of waste water by a wide margin, so needs the improvement design of pertinence.
