Sodium tripolyphosphate is an inorganic substance, also known as pentasodium tripolyphosphate, sodium tripolyphosphate, pentasodium phosphate, white crystal. Molecular weight 367.86. Soluble in water. Anhydrous and hexahydrate are common. The anhydrous matter is stable and the hydrate has hygroscopicity. The solubility of hexahydrate in water is less than that of anhydrous matter. It has good ability to complex metal ions and can complex with calcium, magnesium and iron to form soluble complexes. It has the functions of suspension dispersion, gelation and emulsification. It is mainly used as an additive for synthetic Detergent. It is also used as soft water agent, pretanning agent, dyeing assistant, etc. Using wet process phosphoric acid as raw material, neutralization reaction with sodium hydroxide was carried out by spray drying. Sodium tripolyphosphate is used as a softener, dispersant and dyeing assistant. It is used as softener for industrial water to reduce the content of calcium, magnesium, iron and other metal ions in industrial water and reduce the hardness of water; It is used as dispersant in industrial configurations such as paint, kaolin, magnesium oxide and calcium carbonate, and as dispersant for drilling mud. In addition, it can also be used as water reducer for detergent additives, food additives, gypsum and other molds.
