Storage Environment Of Ion Exchange Membrane:
Before use, please store Enhanced Ion Exchange Membrane in a clean, dry and temperature-controlled environment. Avoid prolonged exposure to extremely high or low temperatures to prevent material performance degradation.
The storage area is well ventilated and the membrane material is not exposed to direct sunlight or ultraviolet light for a long time to prevent aging.
Avoid direct contact with harmful chemicals such as organic solvents, strong acids and alkalis, and oxidants during storage to prevent chemical corrosion.
Notes Of Ion Exchange Membrane:
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).
