Correct pretreatment is necessary to ensure the high performance of the ion membrane. If there are wrinkles in the ion membrane during installation, it will cause uneven current distribution, and the wrinkles will stick to the cathode, which will contaminate the ion membrane.

Similar to preservation film. Soak the membrane in 2% sodium bicarbonate or 0.4 sodium hydroxide solution for more than 1 night. If the film has wrinkles, it will be easily damaged and cracked after pressing.
