Sodium hexametaphosphate supplier Aojin Chemical's China Sodium Hexametaphosphate Factory shares its applications.
Sodium hexametaphosphate (chemical formula: (NaPO₃)₆) is an inorganic compound primarily used as a water treatment agent, food additive, and industrial dispersant. It is used in a variety of fields by chelating metal ions, adjusting pH, and dispersing suspended particles.
Sodium hexametaphosphate is a white powder or transparent flaky solid that is readily soluble in water, with its aqueous solution being weakly acidic. Its core function stems from its long-chain polyphosphate structure, which forms stable complexes (chelation) with metal ions such as calcium and magnesium, preventing precipitation. Furthermore, it disperses particles through charge repulsion, improving solution stability.
II. Main Applications
1. Water Treatment
It is used in industrial circulating water systems to prevent pipe clotting by chelating metal ions. It can also help reduce scale and slow down equipment corrosion. In drinking water treatment, it can assist in removing heavy metal impurities, but the dosage must be strictly controlled.
2. Food Industry
As a food additive (E452i), it is used in meat products, beverages, and other products to improve texture and extend shelf life. For example, it retains moisture in ham and prevents protein denaturation; and in juice, it prevents flocculation.
3. Detergents and Cleaners
3. As a builder in detergents, it softens hard water and enhances cleaning power, especially in water containing high levels of calcium and magnesium ions.
4. Ceramics and Textiles
4. As a dispersant in ceramic slurries, it improves fluidity; in textile printing and dyeing, it prevents dye clumping and ensures uniform coloring.
5. Storage and Purchasing Recommendations
Store in a sealed, moisture-proof container, avoiding high temperatures and strong acids.
