Cationic Resin
- Product Description
-
- Commodity name: Cationic Resin
Application: Water Softening: Cationic resins, particularly in the sodium form, are crucial for removing hardness-causing cations like calcium and magnesium from water, making it softer.
Chemical Name:Cationic Resin
Shape:Spherical beads (typically 0.3–1.2 mm in diameter)
Components: Cross-linked polystyrene-divinylbenzene (PS-DVB)
Other names:
Cation exchanger, SAC resin (Strong Acid Cation), WAC resin (Weak Acid Cation), Hydrogen form resin (H⁺) or Sodium form resin (Na⁺)
Molecular Formula: Not fixed (polymer with repeating units, e.g., [C₆H₄(SO₃H)CH=CH₂])
Molecular Weight: Varies (high molecular weight polymer, typically >10.000 g/mol)
CAS Number:
Strong Acid Cation Resin (Sulfonated): 9085-06-5
Weak Acid Cation Resin (Carboxylic): 9065-55-2
Application:
Water Softening: Cationic resins, particularly in the sodium form, are crucial for removing hardness-causing cations like calcium and magnesium from water, making it softer.
Demineralization: These resins, often used in combination with anionic resins, can remove all dissolved salts from water, producing high-purity demineralized water.
Wastewater Treatment: They can remove heavy metal ions and other harmful cations from industrial wastewater, contributing to cleaner water discharge.
Condensate Polishing: In power plants, cationic resins help remove impurities from condensate water, protecting equipment and improving efficiency.
Acid Catalysis: Strong acid cationic resins can act as catalysts in various chemical reactions.
Biodiesel Purification: They are used to purify biodiesel by removing catalyst residues and other impurities.
Metal Refining: Cationic resins play a role in separating and purifying metal ions in refining processes.
Food Industry: They can be used to improve the quality of food products by removing unwanted ions from water or other solutions.
Pharmaceuticals: Cationic resins are utilized in the purification of pharmaceuticals, including enzymes, hormones, and antibiotics.
Sugar Deashing: They remove ions from sugar solutions, improving the quality and purity of the final sugar product.
Packing:
25 kg HDPE bags
Fiber drums (50 kg, 100 kg)
Storage:
Store in cool, dry conditions (<40°C)
Keep moist to prevent cracking (for H⁺ form, avoid drying)
Avoid contact with oxidizers (e.g., chlorine, HNO₃)
Seal containers to prevent CO₂ absorption (affects weak acid resins)
