An anion-exchange membrane which is adhered in tube shape is sleeved on a polymer framework, the polymer framework is fixedly connected between an anode cap and a cap tail, an electrode is placed inside the polymer framework, the anode cap is covered at the top end of the electrode andis in seal connection with a water outlet pipe via a union joint, and a water inlet pipe is sealed at the bottom end of the electrode through an sealing ring inside the electrode. The tubular anode utilizes the selective and unidirectional anion-exchange membrane to effectively remove organic acid generated during an electrophoresis coating process, reduces corrosion of the electrode and improvesstability of technological parameters.
Description
Technical field
The utility model belongs to the parts scope of electrophoretic painting device, relates in particular to a kind of tubular anode of the pump circulation of the employing union sealing of being with anion-exchange membrane.
Background technology
Ion-exchange membrane is a kind of functional polymer film of selecting perviousness that has.The film of being made up of anion-exchange material is called anion-exchange membrane, and it has the selection perviousness to negatively charged ion, is called for short cavity block.Ability cathode electrophoresis is the coating process that generally adopts, it is the main means that improve coated article work-ing life (erosion resistance), be widely used in industries such as automobile making, machinery, electrical equipment, five metals, give performances such as the good decoration of workpiece, protection against corrosion and weather.In ability cathode electrophoresis, the electrophoretic paint that is adopted is the resin and the pigment slurry of cationic (positively charged), and coated article is as negative electrode.Initial reaction on negative electrode is that water electrolysis forms hydrogen and hydroxide ion (OH-), this reaction causes cathode surface to produce the high alkalinity interfacial layer, make the aggegation on negative electrode of positively charged particle, positively charged ion (resin and pigment) produces the deposition of filming with hydroxide ion (OH-) reaction.Constantly produce organic acid in the positive column, these acid as untimely removing will make tank liquor pH value descend, and influence the stable of processing parameter, influence throwing power, and the solvability of filming again increases, and the consumption of electrode of positively charged is accelerated simultaneously.
Summary of the invention
The utility model purpose is to provide a kind of tubular anode at the deficiencies in the prior art, by water inlet pipe 1, rising pipe 2, union formula joint 3, anode cap 4, pull bar 5, electrode 6, anion-exchange membrane 7, macromolecular scaffold 8, utmost point inner seal ring 9, cover tail 10 is formed, it is characterized in that, bonding one-tenth piped anion-exchange membrane 7 is enclosed within on the macromolecular scaffold 8, macromolecular scaffold 8 is fixed on anode cap 4 and the cover tail 10, electrode 6 places in the macromolecular scaffold 8, union formula joint 3 is tightly connected anode cap 4 and rising pipe 2, and water inlet pipe 1 is implemented sealing in electrode 6 bottoms by utmost point inner seal ring 9.
Described electrode 6 is by pull bar 5 and power turn-on.
Described anion-exchange membrane is to be made of vinylbenzene quaternary ammonium type anion exchange resin and polyethylene.
The material of described macromolecular scaffold is PP, UPVC or ABS; Endoporus is rectangle or square.
The material of described electrode is through the 316L of transpassivation stainless steel or is coated with ruthenium titanium electrode.
The beneficial effects of the utility model are to use selection type, unidirectional anion-exchange membrane to remove the organic acid that produces in the electrophoretic painting process effectively, have reduced the corrosion of electrode; Realize the processing of electrode solution exit seal by union formula joint, force the anolyte Rapid Cycle, improve the stability of processing parameter.
