Chelating Resins for Membrane Caustic Soda
Chelating resins are types of cross linked functional polymer material which can be formed polydenate chelate complex with metal ions. Compared with ion-exchange resins, chelating resins have stronger bonding force to link with metal ions with high selectivity. It can be used to separate and recycle metal ions into various fields such as amine acid separation, wet metallurgy and prevention of the social effect of pollutants.
Chelating Resins Special for Membrane Caustic Soda
To increase the effective and prolong the life of membrane, membrane caustic soda requirs highly purified brine water. However, traditional depositing technique can hardly meet the requirement. Our products LSC-500 and LSC-100 amino carboxylic acid chelating resin are able to effectively remove harmful ions like Ca2＋， Mg2＋， Sr2＋ therefore making secondary brine water fully satisfying requirements for membrane technique.

Characteristics of Chelating Resins LSC－500 / LSC-100 when used in preparation of secondary brine water of membrane.
- Strong Resistance to penetration and shock
- Hige volumetric chelating capacity
- Uniform particle size
- Exported to USA for last five years and applied at home by more than 30 enterprises
High strength of resistance to wear and penetrate, low wastage rate, low annual supplement quantity, stable hydraulics performance.
Hige exchange capacity makes larger quantity of brine water in one cycle, effectively removal Ca2+ Mg2+ Sr2+, etc..
Excellent regeneration operation kinetics performance
