Electrolyte concentration and temperature: The difference of electrolyte concentration directly affects the conductivity of electrolyte by controlling the amount of ions in electrolyte. At low concentration, the conductivity of electrolyte increases linearly with the increase of concentration. When the high concentration range is reached, the later change of conductivity is no longer significant. The effect of temperature on electrochemical treatment is similar to that of concentration, mainly by affecting the movement of ions in electrolyte. According to the law of thermodynamics, the activity of ions increases with the increase of temperature.
Electrolyte concentration and temperature have a direct impact on the current efficiency in the process of processing, and this effect is different for linear electrolyte and non-linear electrolyte. At the same time, when the temperature and concentration of the electrolyte change, the viscosity of the electrolyte itself changes accordingly, which affects the flow characteristics of the electrolyte.
Therefore, the selection of appropriate electrolyte concentration and temperature will directly affect the polishing efficiency and speed of electrochemical polishing of stainless steel square tubes. However, the effect of electrolyte concentration and temperature on the efficiency of electrochemical treatment is complex. So far, the experimental research in this area is not enough.
