Mixed Ion Exchange Resin Nuclear Grade Material And Performance Indexes

 

Mixed ion exchange resin from Hebei Lijiang Biotechnology Co., Ltd. meets strict nuclear grade quality standards, composed of cation and anion resins in a precise volume ratio (1:1.5 V/V) to ensure efficient ion removal. The cation resin uses a styrene-DVB copolymer gel-type polymer with -SO3 functional groups, achieving a conversion rate of ≥99% H+ and a volume exchange capacity of ≥1.75mmol/ml—critical for capturing cationic impurities in water. The anion resin, also a styrene-DVB copolymer, features -N(CH3)3 functional groups, with ≥90% OH- conversion and ≥1.1mmol/ml volume exchange capacity, targeting anionic contaminants .

Mixed Bed Water Softener Resin Compatibility For Efficient Water Treatment

 

Mixed bed water softener systems from Hebei Lijiang Biotechnology Co., Ltd. rely on the company’s mixed ion exchange resin for efficient water softening, designed to remove hardness-causing ions and other impurities in one step. The resin’s cation component exchanges H+ for calcium/magnesium ions, while the anion component swaps OH- for chloride/sulfate ions—together, they produce soft, high-purity water suitable for industrial boilers, food processing, and pharmaceutical production. Hebei Lijiang Biotechnology Co., Ltd. ensures the resin is fully compatible with mixed bed water softener designs, with water retention capacity optimizing moisture balance for continuous operation.

Mixed Bed Ion Exchange Process And High-Purity Water Production

 

Mixed bed ion exchange technology from Hebei Lijiang Biotechnology Co., Ltd. leverages its mixed ion exchange resin to produce ultra-high-purity water, a critical process for sectors like semiconductor manufacturing, nuclear energy, and laboratory research. The process works by passing raw water through a mixed bed column filled with cation and anion resins: as water flows, cations  bind to the cation resin’s -SO3 groups , and anions  attach to the anion resin’s -N(CH3)3 groups. The H+ and OH- combine to form pure water, resulting in output with minimal total dissolved solids.

 

Product Information	Details	High-Purity Production Advantage
Core Mechanism	Cation resin (H+ exchange) + Anion resin (OH- exchange)	Removes cations/anions; produces ultra-pure water
Resin Optimization	1:1.5 V/V ratio; ≥95% whole bead count	Balances exchange rates; no channeling
Pre-Treatment Requirement	Flocculation, filtration, sand filtration	Prevents resin pore blockage
Target Purity	Minimal TDS; meets nuclear/pharmaceutical standards	Suitable for semiconductors, nuclear energy
Cost Efficiency	Polishes RO water; lower cost than multi-step methods	Reduces end-user production costs

 

Mixed Ion Exchange Resin Storage And Wholesale Support

 

Mixed ion exchange resin from Hebei Lijiang Biotechnology Co., Ltd. requires specific storage conditions to maintain performance, and the company provides detailed guidance for wholesale clients and end-users. The resin must be stored in a wet state, with temperatures above 0℃ to avoid freezing. For long-term storage, it should be placed in a closed container or 5%+ salt water to prevent dehydration. During transportation, anti-freezing measures are mandatory, and heavy objects must not be placed on resin containers to avoid bead crushing.
