For professionals in chemical processing, water treatment, and pharmaceuticals, a thorough understanding of product specifications is vital for making informed purchasing decisions. NINGBO INNO PHARMCHEM CO.,LTD. provides detailed technical data for its Macroporous Acrylic Acid Series Weakly Alkaline Anion Exchange Resin, emphasizing key physical and chemical properties that dictate its performance and suitability for various applications.

The resin's structure is based on a Methyl acrylate-divinylbenzene polymer matrix, which forms a macroporous spherical particle with a light yellow opaque appearance. This structure is engineered to provide a large surface area and optimized pore distribution, facilitating efficient ion exchange. The functional groups are amine-based (-NH2), classifying it as a weakly alkaline anion exchange resin. This classification is critical as it determines the resin's selectivity and capacity for different types of anions.

Key performance indicators include a total exchange capacity of ≥2.0 eq/l (wet, volumetric) and a moisture retention of 54-64% in its Free Base form. The particle size range of 0.3mm-1.2mm with a maximum of 1% below 0.3mm ensures good hydraulic properties and minimizes fines. A uniformity coefficient of 1.6 and an effective size of 0.4-0.7mm are within optimal ranges for efficient bed expansion and flow rates during operation. The reversible swelling from FB to Cl- is a maximum of 15%, indicating good stability during regeneration cycles.

Understanding these specifications, such as shipping weight (approx. 660-730 g/l) and specific gravity (1.10 moist FB Form), helps in designing and sizing treatment systems accurately. The pH range for stability (1-9) is also a crucial parameter, indicating the operational limits within which the resin can effectively perform without degradation. When considering the purchase of these resins, reviewing the technical data provided by manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. is essential to ensure the chosen product aligns with specific application requirements, thereby maximizing efficiency and value. The competitive pricing makes these high-specification resins accessible for a wide range of industrial needs.
