Comprehensive Guide to Deionization Resin in China

Deionization resin is a critical component in water treatment processes, especially for industries requiring ultra-pure water. This guide explores various aspects of deionization resin, focusing on its types, technical features, and notable manufacturers in China, including felitecn.com, www.lanlangcorp.com, www.newater.com, and www.seplite.com.

Understanding Deionization Resin

Deionization resin is a type of ion exchange resin used to remove charged particles (ions) from water. The process involves exchanging undesirable ions with hydrogen (H+) and hydroxide (OH-) ions to produce deionized water. This water is essential in various applications, such as pharmaceuticals, electronics, and laboratories.

Technical Features of Deionization Resin

To provide a clearer understanding of the technical specifications of deionization resins, the following table summarizes key features:

Feature	Description
Chemical Composition	Typically made from polystyrene with functional groups.
Ionic Form	H+ (cation), OH- (anion), or Na+ (for softening).
Resistivity	> 18 MΩ.cm for high purity applications.
Operating Temperature	Up to 60°C for most resins.
Particle Size	Ranges from 0.315 mm to 1.25 mm.
Moisture Content	Approximately 55-61%.
Density	1.06-1.20 g/ml.
Capacity	Total exchange capacity around 0.5 eq/L.

Types of Deionization Resins

Deionization resins can be categorized into different types based on their ion exchange capabilities. The following table compares the primary types of deionization resins:

Type	Description	Applications
Strong Acid Cation (SAC)	Removes divalent and monovalent cations, typically used in softening and demineralization.	Water softening, industrial deionization.
Weak Acid Cation (WAC)	Primarily removes temporary hardness and alkalinity.	Dealkalization, softening applications.
Strong Base Anion (SBA)	Removes strong anions such as sulfate, nitrate, and chloride.	Water purification, wastewater treatment.
Weak Base Anion (WBA)	Effective for weakly ionized anions; less common than SBA.	Specialty applications in pharmaceuticals.
Mixed Bed Resins	Combines SAC and SBA for high-purity water.	Final polishing in ultrapure water systems.
