Performance Characteristics
- White granular or powder with density of 0.35-0.90 g/cm3 and melting point of 622°C
- Easily soluble in water with alkaline aqueous solution (pH 9.7 for 1% solution)
- Gradually hydrolyzes into phosphite in water with excellent metal complexation ability
- Forms soluble complexes with calcium, magnesium, iron and other metal ions
- Effective water softener with inorganic surfactant properties
Applications
- Synthetic detergent additive and soap agent
- Prevents bar soap grease precipitation and frosting
- Industrial water softener for tanning, dyeing, and paint industries
- Dispersant for kaolin, magnesium oxide, calcium carbonate suspensions
- Drilling mud dispersant and paper industry anti-oil agent
Water Softening Mechanism and Applications
Water Softening Principles
- Chelating effect: Combines with Ca²⁺ and Mg²⁺ ions to prevent scale formation
- Dispersion effect: Prevents scale deposition in pipelines and equipment
- Corrosion inhibition: Forms protective film on metal surfaces
Primary Application Scenarios
Boiler water treatment: Prevents scaling, improves thermal efficiency (use below 80°C)
Industrial cooling water: Reduces calcium/magnesium deposition in cooling systems
Textile industry: Softens water, prevents dye sedimentation
Detergents: Enhances cleaning performance in hard water
Purchase Recommendations
- Select industrial-grade STPP with ≥94% purity
- Conduct small-scale dosage tests before full implementation
- Verify supplier credentials and request MSDS documentation
