Sodium Hexametaphosphate

Sodium hexametaphosphate (SHMP), also known as Graham’s salt or Calgon, is a chemical compound with the formula (NaPO3)6. It is a white, crystalline powder that is soluble in water.

Uses:

• Water Treatment: Sodium hexametaphosphate is commonly used in water treatment processes as a sequestering agent and scale inhibitor. It helps to prevent the formation of scale deposits and control water hardness by binding with metal ions such as calcium and magnesium, which can cause scaling and fouling in pipes, boilers, and heat exchangers.
• Food Industry: In the food industry, sodium hexametaphosphate is utilized as a food additive and emulsifying agent. It is added to processed cheese, dairy products, canned seafood, and meat products to improve texture, stability, and shelf life. It also helps to prevent the coagulation or separation of ingredients and enhances the dispersion of fat and oil.
• Industrial Applications: Sodium hexametaphosphate may find applications in various industrial processes, including metal cleaning, textile processing, and paper manufacturing. It is used as a dispersant, chelating agent, and emulsifier in these applications to improve processing efficiency and product performance.
• Detergents and Cleaning Products: Sodium hexametaphosphate is added to detergents, cleaners, and industrial degreasers as a builder and water softener. It helps to enhance the cleaning effectiveness of these products by sequestering metal ions and preventing the formation of insoluble mineral deposits on surfaces.
• Photography: In the photography industry, sodium hexametaphosphate is used as a flocculant and dispersant in the processing of photographic films and papers. It helps to control the dispersion of silver halide particles and improve the development process
