Precautions For Using Ion Exchange Membranes:
During the electrolysis or electroplating process, ensure the purity of the electrolyte solution and avoid impurities that may cause membrane material degradation.
Regularly check the status of the electrolytic cell and membrane, remove the sediment in the cell in time, and keep the membrane surface clean in order to improve the electrolysis efficiency of Proton Exchange Membranes for Electrolysis and extend the service life of the membrane.
Avoid electrolysis without electrolyte solution to avoid damage to the membrane material.
Notes Of Ion Exchange Membranes:
Measurements taken with membrane conditioned to 23℃, 50% RH for 24h.
Conductivity measurement taken at 23℃, 100% RH.
A base titration procedure by using the caustic soda measures the equivalents of sulfonic acid in the membrane, thus calculating the acid capacity or equivalent weight of the membrane.
Water content of membrane conditioned to 23℃ and 50% RH (dry weight basis).
Water uptake of dry membrane conditioned in water at 100℃ for 1 hour (dry weight basis).
