High Quality Sodium Tripolyphosphate 94% STPP for Detergent and Ceramic
Sodium tripolyphosphate has the functions of chelating, suspending, dispersing, peptizing, emulsifying, pH buffering, etc. It can be used as the main auxiliary agent of synthetic detergent, industrial water softener, leather pretanning agent, dyeing auxiliary agent, organic synthesis catalyst , Pharmaceutical industry dispersant and food additives, etc. In addition to exporting STPP, domestic STPP consumption is mainly concentrated in the detergent industry, food, ceramics, etc. In water treatment, it is mainly used as a water softener. Sodium tripolyphosphate has the performance of an ion exchanger and can form a soluble complex with calcium, magnesium and iron ions in the water. Na3MP3O10 (M is a metal ion) [5], It shields the effect of calcium and magnesium hard salts and prevents the formation of calcium and magnesium deposits. In addition, because of its surface activity and strong buffering effect (the buffering effect in the pH range of 4-14 is the best), it can also be used as a corrosion inhibitor.
