Performance Characteristics
  • White granular or powder, showing a density of 0.35-0.90G/CM3, melting point 622°C
  • Easily soluble in water, the aqueous solution is alkaline (PH of 1% aqueous solution is 9.7)
  • Gradually hydrolyzed into phosphite in water
  • Excellent metal complexation ability - can complex with calcium, magnesium, iron and other metal ions to produce soluble complexes
  • Softens hard water
  • Functions as an inorganic surfactant with some properties of organic surfactants

Industrial Applications
1. Detergent Industry (Core Uses)
  • When compounded with surfactants (such as LAS), enhances decontamination power and prevents redeposition of dirt
  • Softens hard water by chelating Ca²⁺ and Mg²⁺, enhancing washing effect
  • Alternative technologies for phosphorus-free detergents exist due to environmental restrictions (eutrophication), but still widely used in industrial cleaning agents
2. Processing (-grade STPP)
  • Moisture retention agent for meat and sea (ham, fish balls) to enhance water retention and improve taste
  • Inhibits fat oxidation to extend shelf life
  • Quality improver - enhances elasticity in noodles and canned , prevents starch from aging
3. Industrial Water Treatment
  • Water softener and scale inhibitor for boiler water and circulating cooling water systems
  • Prevents Ca/Mg scaling and chelates metal ions (Fe³⁺, Cu²⁺) to reduce pipeline corrosion
  • Dispersant to prevent particle aggregation in papermaking and ceramic slurries
4. Other Industrial Applications
  • Petroleum industry: Drilling mud additive for viscosity and stability control
  • Textile printing and dyeing: Bleaching assistant to improve dye uniformity
  • Metal surface treatment: Component of cleaning agents before electroplating for removing grease and oxides
