Ion Exchange Resin

Sunresin developed food grade Seplite® LSF983 series of macroporous weak acid cation resin based on a polyacrylate matrix. The Seplite LSF983® is very suitable for hardness (calcium and magnesium) removal from potable water (household water filters, pitchers etc), beverage and food applications. Besides hardness, it can also help to reduce certain level of heavy metals as Copper, Lead etc.

The ion exchange resin (IER) method is very excellent and efficient for acetone purification. Acetone will pass cation exchange resins first and then the anion exchange resins, more than 95% methylamine will be removed.

Application of Mixed Bed Ion Exchange ResinSEPLITE® Ion Exchange Resins are very versatile in their application: one of them is the use as a mixture of Cation and Anion exchange resins also known as Mixed Bed (MB). Mixed Beds allow to perform an efficient demineralization in one process step: by intimately mixing highly regenerated Cationic and Anionic resins a Mixed Bed represents a succession of a huge number of Cationic and Anionic exchanger beds leading to a very high purity of the treated water.

Softening resins are categorized into solvent or Non-solvent products depending on whether dichloroethane solvent is used in the resin manufacturing process. Dichloroethane residues though trace amount may exist in the effulent extractions of solvent resins, but will never exist in Non-solvent resins.

Storage life of unused ion exchange resin under appropriate conditions Under appropriate conditions: store in a dry, cool and unopened package at 5-30℃

The color indicator resin is introduced into gel type anion or cation exchange resin through a special process, which makes the color changes under different ion types. It is convenient for users to judge the exhaustion state of ion exchange resin directly.

The performance of ion exchange resin is affected by many factors. If abnormal performance degradation of ion exchange resin occurs in daily use, we generally carry out the cause analysis and take corresponding measures according to the following sequence.

The strong base anion exchange resin contains a certain amount of moisture and should not be stored in the open air. During the storage and transportation, it should be kept moist to avoid air drying and dehydration, which will cause the resin to break. If dehydrated during the storage, the resin should be soaked in concentrated salt water (25%) and then gradually diluted. Do not put the resin into water directly in case of rapid expansion and breakage.
