A Comprehensive Guide to DI Resin in China
Demineralization (DI) resin is a crucial component in water purification processes, particularly in industries requiring high-quality deionized water. In China, several manufacturers and suppliers specialize in DI resin, providing customized solutions to meet diverse needs. This guide explores the technical features, types, and applications of DI resin, focusing on key suppliers such as Lanlang Corp, UMEK, and Felite.
Understanding DI Resin
DI resin is an ion exchange resin used to remove dissolved ions from water, effectively producing demineralized water. This process is essential in various applications, including pharmaceuticals, electronics, and aquaculture, where water purity is paramount. The resin works by exchanging undesirable ions in the water with hydrogen and hydroxide ions, resulting in high-quality deionized water.
Technical Features of DI Resin
The effectiveness of DI resin can be evaluated based on several technical features. Below is a comparison table highlighting these features:
| Feature | Description |
|---|---|
| Ionic Form | Typically available in H+ (cation) and OH- (anion) forms. |
| Moisture Content | Varies between 40% to 60%, affecting the resin’s capacity and performance. |
| Bulk Density | Ranges from 0.65 to 0.87 g/ml, influencing the resin’s handling and efficiency. |
| Volumetric Exchange Capacity | Generally ≥1.2 mmol/ml, indicating the resin’s ability to exchange ions. |
| Effective Diameter | Typically between 0.3 to 1.25 mm, affecting flow rates and filtration efficiency. |
| Uniformity Coefficient | Should be ≤1.6 for optimal performance, indicating bead size consistency. |
| Osmotic Attrition | Should be ≥90%, ensuring durability and longevity of the resin. |
Types of DI Resin
DI resins come in various types, each designed for specific applications and performance requirements. The following table compares the different types of DI resin available in the market:
| Type | Description | Applications |
|---|---|---|
| Gel Type | Composed of small beads with a consistent gel structure. | Commonly used in electronics and pharmaceuticals. |
| Macroporous Type | Features larger pores, allowing for higher flow rates and better fouling resistance. | Ideal for high-temperature applications. |
| Mixed Bed Resin | Combines both cation and anion resins in a single unit for comprehensive demineralization. | Used in aquaculture and ultrapure water systems. |
| Indicator Resin | Changes color to indicate exhaustion, providing a visual cue for regeneration. | Useful in applications requiring frequent monitoring. |
Applications of DI Resin
DI resin is widely used across various industries due to its ability to produce high-quality deionized water. Key applications include:
