Long-term storage of ion membranes

No matter where the membrane is, as long as it is used, it should not be easily removed! The best way is to save it on the battery tank! And keep it moist! Wash it at least once a week! Note that the membrane should always be attached to the anode!
During shutdown and maintenance, especially long-term shutdown, the membrane must be protected. The best way is to protect it directly on the electrolyzer. Asahi Kasei electrolyzers only need to moisten the membrane with pure water every week, but when moistening, be careful that the membrane must be close to the anode. ； Chlorine engineering electrolyzers need to be filled with pure water and light alkali to moisten the membrane every other day. It is also important to note that the membrane must be close to the anode.
Of course, it is best to store it in a battery tank, keep it moist, and always pay attention to the positive pressure difference. . . . . . . . .
Our company is a chlorine engineering company. When parking, we use 200 salt water and 31 alkali to pass the polarization current.
We also use chlorine engineering. In the later stage, pinholes will appear in part of the film, and the alkali solution from the cathode will enter the anode. Will it corrode the anode titanium plate?
After wetting is completed, should pure water and light alkali be discharged? If the emission concentration is too low, will the membrane bubble?
There is no problem. Our company has been using the tank for 5.5 years. The indicators are pretty good.
