Durable Membranes Offer High Permselectivity for Industrial
ProcessesSybron Chemicals Inc. manufactures IONAC
brand heterogenous ion exchange membraneswith strong acid
cationic and strong base anionic functionality.
These membranes, with their strongly ionizedfunctionality yield
high permselectivity forindustrial processes. The combination of a
verystrong fabric base and a chemically stablebinder yields a very
tough membrane. Theirhigh Mullen Burst Strength ratings will
notdegrade within their normal operating tempera-ture range.
Ion exchange membranes are used in a variety of
processing and waste treatment applicationsthat include:n
Production of Periodic acidn Recovery of metals from electroplating
and
metal finishing bathsn Recovery of pickle liquorsn
Electrocoating for both anionic and cationic
systems.
IONAC ion exchange membranes come in two precut sheet sizes.
In
addition, our MA-7500 membrane comes instandard-size rolls 43 or
45 inches wide, inlengths up to 30 meters (see table below).
The3400 series membranes are available as a spe-cial order in sheet
sizes up to 65 inches wide by144 inches long.
IONAC ion exchange membranes are furnisheddry for ease of
storage. The membranes shouldbe stored in the shipping canister
provided bySybron Chemicals Inc., in a dry environment.They should
be presoaked before use, followingthe instructions in the membrane
preparationsection, to obtain dimensional swelling.

Typical Membrane Characteristics
Membranes should be prepared for service by following either
method listed below. By doing so, you will help ensure a long
useful life for your membrane material.
Method A: The membranes should be completely immersed in a
solution that is typical in composition to theliquid contacting the
membrane in the system. It is preferable that this liquid be at a
temperature of up to butnot exceeding 55C to expedite equilibrium.
Allow a contact time of 3 hours to ensure complete swelling.
Method B: As an alternative to equilibrating in the application
liquor, the membrane can be soaked in awater or brine solution
under the same temperature and time conditions as stated above.
