Description

The ability cathode electrophoresis electrode system

Technical field

The utility model relates to a kind of electrode system that is applied to the ability cathode electrophoresis industry.

Background technology

Along with the development of modern application techniques and the raising that requires for coating quality, ability cathode electrophoresis is with its spraying main flow even, corrosion-resistant, mar-proof, that high-performance salt spray resistance has occupied the conductor workpiece gradually of filming.

In electrophoresis process, the factor of restriction coating quality mainly contains the quality of pre-treatment, the quality of cathode electrodip painting, the quality of electrode system, the electrode system that at present a large amount of electrophoresis producers adopts all is front and back voltage unanimities, be workpiece when just having entered major trough with enter major trough fully after voltage identical, such setting just begins to carry out electrophoresis with high-voltage when making workpiece just enter major trough, produce very big rush current, accelerated the corrosion speed of the anode tube of close major trough front end, and make workpiece surface produce " band " phenomenon easily, influence the quality of application; Generally be the simple circulation of carrying out anolyte for anode system, can't accomplish the real-time monitoring of antianode liquid, can not judge the problem that will occur in the electrophoresis process intuitively, too high as specific conductivity, or the turbidity of anolyte is excessive, will produce influence greatly to film quality in case these problems accumulate.

The utility model content

The utility model has solved prior art, and to occur front end anodic corrosion in electrophoresis process too fast, and the problem of can't antianode liquid monitoring in real time provides the ability cathode electrophoresis electrode system that a kind of circulating effect is good, can control the anolyte specific conductivity automatically.

For achieving the above object, the technical solution of the utility model is:

The ability cathode electrophoresis electrode system, comprise major trough, secondary groove, catenary system, rectifier cabinet, the anolyte storage tanks, be connected with the anolyte vent pipe on the described anolyte storage tanks, upflow tube and pure water input tube, be connected with ball valve on the described anolyte vent pipe, rectifier cabinet is divided into low pressure area and high pressure area, low pressure area links to each other with the first anode, and the high pressure area links to each other with second anode, the first anode, be connected with anolyte input tube and anolyte output tube between second anode and the anolyte storage tanks, be connected with the anolyte recycle pump on the described anolyte input tube, be connected with transmissometer on the anolyte output tube, also be connected with conductivitimeter on the anolyte storage tanks, conductivitimeter links to each other with magnetic valve on the pure water input tube.

As the further setting of such scheme, the low pressure area of described rectifier cabinet and the voltage of high pressure area differ 40V at least.

The beneficial effects of the utility model are: realized the real-time monitoring of specific conductivity and the turbidity of antianode liquid, and can regulate the specific conductivity of anolyte and find the potential problems that anode system exists according to real-time working condition, by electrode being divided into low pressure area and high pressure area, slowed down the corrosion speed of front end anode tube.
