Cation Exchange Membrane

Mainly for hydrogen-oxygen electrodialysis, desalination, water electrolysis.
Cation Exchange Membrane
Color Light: Yellow
Standard Size: Metric 0.8m x 1.6m
Standard thickness(mm): 0.25-0.28
Electrical Resistance (Ohm/cm2 ) less than 4.0
Permselectivity (%) :96.2
Total Exchange Capacity (mol/kg) more than 1.4
Mullen Burst Test strength(Mpa) more than 0.9
Thermal Stability (°C) less than 50
Membrane potential(Mv) 14.9(14°CLiquid temperature)
Moisture Content(%) 40-70
transference number of ions less than 0.95
Storage:

1, wet condition preservation. Homogeneous ion exchange membrane according to the
different brand, shrinkage in 710 % respectively, between dehydrate condition will slowly
contraction.
2, preservation temperature: 5-40%.
3, handling and storage, prevent extrusion, folding for damages caused to the deformation.

How to use:

1, Open the package, carefully examine labels and cabinet material, lest produce errors.
2, roller is removed, the entire processing (cutting film, stiletto) and assembling process, the
membrane surface must keep sufficient moisture, otherwise, it will lead to film contraction,
the influence is used (can use sprinkling water bottles evenly to membrane sprinkler).
3, assembly, coping clapboard electrodialysis equipment before and isolated nets
(key is welding parts) to inspect, be sure to level off, smooth, no burr, otherwise will
membrane punctured, thus causing losses.
4, assembly electrodialysis equipment, should be careful operation and will end with the
roller on the one end (right side clapboard alignment, alignment, then) along the clapboard
downward end provinces, such as membrane expanded without betweent (deviated from
clapboard) is required to reopen the roller is good, adjust good position to relaunch and may
not be directly raise, or with membrane fingers hook lives film hole Angle adjustment, such as
extremely easily, cause loss will tear film.
5, enter electrodialysis solution (or water) shall undergo pretreatment, feed unusualness
degrees < 1, pollution index (namely mud density index) FI10 < 3-5 (ED)
6, electrodialysis equipment during the discontinuation, should maintain machine has
sufficient moisture, otherwise it will cause membrane shrink and damage, need not when,
best will membrane removed, soak in water.
