1. Introduction
Fumasep FKD-PK-75 is a PK reinforced Cation Exchange Membrane (CEM) with low resistance, high selectivity, high mechanical stability, and high stability in caustic environment.
2. Delivery
The membrane is the brown foil, delivered in between paper layer. Carefully separate the membrane from the paper layers. The membrane is delivered in dry form.
The standard size of this membrane is 10*10cm & 20*30cm. Customized dimensions can be made upon request.
3. Precautions
Fumatech membranes are highly sensitive to differences in humidity and moisture content. Therefore the membranes can vary +/- 0.5cm from the original cut sizes. Also due to this sensitivity the manufacturer expects wrinkles to form, however soaking the membranes in deionized water will return the membranes to the full size planar state according to the manufacturer.
- Applications: Diffusion dialysis for caustic solutions.
- Cation Exchange Membrane
- Stability range (pH) at 25 °C: 1 - 14
- Thickness: 75 micrometers (μm)
5. Welcome to cite our materials in your papers
Fumasep FKB-PK-130, a PEEK reinforced Cation Exchange Membrane (CEM), was obtained from SCI Materials Hub.
Keep membrane package closed / sealed when unused. Unpack membrane only for direct use and process it immediately after opening. Store, handle and process the membrane in a clean and dustfree area. Use only new and sharp knives or blades, when cutting the membrane.
Always wear protective gloves when handling the membrane. Handle with care, be sure not to puncture, crease or scratch the membrane, otherwise leaks will occur. All surfaces which may get into contact with the membrane during inspection, storage, pretreatment and mounting must be free of sharp edges or angles.
Dry form: Storage for long time scale (> 12 month) may be done in dry state (sealed container).
Wet form: Storage for short and medium time scale (hours up to several weeks) may be done in unsealed containers in 0.5 – 1.5 wt% NaCl solution or comparable neutral pH electrolytes.
For storage over a longer time period a sealed container is recommended using afore said electrolyte with additional sodium sulfite (Na2SO3) in concentration 1 – 3 wt% to avoid biological fouling.
The membrane changes dimensions based on its water content.
Membranes are delivered in H+ form and dry form. Depending on application and cell design, assembling is possible in dry (without pretreatment) or wet form.
Pretreatment before assembling: put the membrane sample between stabilizing meshes / spacers (in order to avoid curling) in NaCl solution - e.g. 0.5 M NaCl solution at T = 25 °C for 72 hrs exchanging several times the solution.
Do not let the membrane dry out since micro-cracks may likely occur during shrinkage.
If you have any concerns about storage, chemical stability and pretreatment before proceeding, please feel free to contact us for further information.
