Application

 

1. Water Treatment Industry

Primary Functions:

• Scale Inhibition:

  • Chelates Ca²⁺/Mg²⁺ ions to prevent scale formation in boilers, cooling towers, and reverse osmosis systems

  • Effective at concentrations as low as 2-10 ppm

• Corrosion Control:

  • Forms protective films on metal surfaces (especially carbon steel)

  • Often blended with zinc salts for enhanced performance

• Municipal Water Softening:

  • Reduces water hardness by sequestering metal ions

  • Preferred over STPP (sodium tripolyphosphate) due to better solubility

2. Detergent & Cleaning Products

Key Roles:

• Builder Agent:

  • Enhances surfactant efficiency by neutralizing water hardness

  • Maintains alkalinity in heavy-duty detergents (pH 9-11)

• Soil Suspension:

  • Prevents redeposition of dirt on fabrics

  • Critical in laundry powders (typical dosage: 10-25% formulation)

• Dishwasher Detergents:

  • Prevents lime scale on glassware

  • Synergistic effect with sodium carbonate

3. Ceramics & Textile Manufacturing

Ceramic Applications:

• Slip Casting:

  • Disperses clay particles (0.1-0.3% dosage)

  • Reduces viscosity by 40-60% compared to non-treated slips

• Glaze Modification:

  • Controls rheology for even application

  • Prevents cracking in fast-drying processes

Textile Uses:

• Dyeing Process:

  • Improves color uniformity by sequestering metal ions

  • Particularly effective for reactive dyes

4. Oilfield Applications

Critical Functions:

• Drilling Fluids:

  • Controls calcium/magnesium contamination in bentonite muds

  • Maintains fluid viscosity at high temperatures

• Scale Prevention:

  • Squeeze treatment in production wells (5-15% solutions)

  • Effective against CaCO₃scales in downhole equipment

5. Metal Surface Treatment

Process Applications:

• Derusting Solutions:

  • Component in acid pickling baths (HCl/H2SO4 based)

  • Inhibits base metal corrosion while removing rust

• Passivation:

  • Creates phosphate coatings on steel surfaces

  • Often combined with zinc phosphate for automotive parts

6. Paper & Pulp Industry

Functional Benefits:

• Pulp Bleaching:

  • Stabilizes peroxide in mechanical pulp bleaching

  • Dosage: 0.05-0.1% on oven-dry pulp

• Paper Coating:

  • Disperses pigments in coating formulations

  • Improves coating uniformity and gloss

7. Mining & Mineral Processing

Critical Uses:

• Flotation Agent:

  • Depressant for calcium-containing minerals (e.g., calcite)

  • Enables selective separation of target ores

• Slurry Viscosity Control:

  • Reduces viscosity in phosphate rock processing

  • Dosage: 0.01-0.1% of slurry weight
