The titanium anode is the anode of the titanium-based metal oxide coating. The role of the metal oxide coating is: low resistivity, good conductivity (the conductivity of titanium itself is not good), the chemical composition of the precious metal coating is stable, and the crystal structure Stable, stable electrode size, good corrosion resistance, long life, and good electrocatalytic performance, which is beneficial to reduce the overpotential of oxygen evolution and chlorine evolution reactions and save electric energy. Therefore, in the process of anode use, it is particularly important to pay attention to the coating on the surface of the anode.
Matters needing attention
⊙After the anode substrate is pickled, wear a clean glove card during processing or use.
Stay at both ends or edges of the anode and try not to touch the coating part to protect the coating surface from any damage.
Any contamination or scratches from foreign objects. If it is scratched or damaged, during the electrolysis process, the anode will be removed from the
The damaged area is corroded, which affects the use effect of the whole anode.
⊙The electrolyte must be stable, especially not containing hydrogen ion and fluoride ion, otherwise it will seriously corrode titanium
Matrix.
⊙Before the electrolyte enters the electrolytic cell, a filter device must be added, and it must not contain metal particles larger than 0.1mm.
Avoid short circuit of anode and cathode due to excessive accumulation.
⊙The cathode attachment should not be too thick, so as to avoid the short-circuit of the cathode and anode due to the small distance between the electrodes or the formation of sharp metal
Breakdown.
⊙Reasonably adjust the distance between cathode and anode, generally 5 to 25mm.
⊙ Try to avoid the use of the conductive pole, which may cause the coating to fall off and affect the service life.
⊙ Try not to soak in the solution in the power-off mode when stopping, it is best to add a small current protection of about 5A
Protect the cathode plate.
⊙ When pickling or washing the surface of the electrode plate, pay attention to protecting the surface and not scouring it with sharp objects.
⊙ When the electrolyte is working, the temperature should not be too high, the reasonable temperature is 25-40 degrees Celsius.
⊙ Pay attention to the current density during work and keep it within 2000A per square meter. If the current is too large, it will cause adverse reactions.
Should be fierce, affecting the service life of the electrode.
⊙ When starting to load the electrolytic cell with current, it must be done step by step, and do not add it all at once. During shutdown
Also pay attention.
⊙When starting to load the electrolytic cell with current, it must be done step by step, and do not add it all at once. Downtime
Attention should also be paid.
⊙ Keep the surface of the electrode clean, and not be contaminated with oil or other attachments, so as not to affect the electrolysis effect and life.
