Purpose

Sodium hexametaphosphate is an efficient softener used in water softeners, dyeing and finishing industries, power stations, locomotives, boilers, and fertilizer plants for cooling water treatment, as well as cleaning agents for fiber and dyeing industries;
Sodium hexametaphosphate is used as a flotation agent in the mineral processing industry. In the petroleum industry, it is used for rust prevention of drilling control pipes and for controlling the viscosity of mud during oil drilling. It is also used as a refractory in textile printing and dyeing, leather, paper making, detergent additives, cement hardening accelerators, agents for controlling or preventing corrosion, color films, soil analysis, radiochemistry, analytical chemistry and other departments, It can suppress the expansion phenomenon caused by the reaction of iron or iron compounds in refractory materials with acidic chemical binders to produce hydrogen gas, and is a good refractory additive

Sodium Hexametaphosphate (SHMP) is a white crystalline powder that is used in a variety of industrial and food applications. It is a highly effective sequestering agent, which means it can bind to metal ions and prevent them from reacting with other substances. This property makes it useful in industrial processes such as water treatment, detergents, and metal surface treatment.

In the food industry, SHMP is used as a food additive and preservative. It can improve the texture and appearance of processed foods, prevent spoilage, and enhance the flavor of certain products. It is commonly used in dairy products, meat processing, and seafood processing.

The purity of SHMP is measured by its percentage of active ingredient, which should be at least 68%. Higher purity SHMP is also available, with concentrations up to 85%. SHMP is generally considered safe for human consumption when used in the recommended amounts. However, excessive consumption can lead to gastrointestinal problems and electrolyte imbalances.
