Product Description
Chinese name: sodium tripolyphosphate.
Chinese alias: pentasodium phosphate, sodium pyrophosphate, STPP, pentasodium tripolyphosphate.
Performance characteristics: white granular or powdery, easily soluble in water, gradually hydrolyzed into phosphite in water, with good ability to complex metal ions.
Sodium tripolyphosphate has the functions of chelation, suspension, dispersion, peptization, emulsification, pH buffering, etc. It can be used as the main auxiliary agent of synthetic detergents, industrial water softener, leather pretanning agent, dyeing auxiliary, organic synthesis catalyst, pharmaceutical industry dispersant and food additive, etc. In addition to exporting STPP, domestic STPP consumption is mainly concentrated in the detergent industry, food, ceramics, etc.
Uses:
1. Mainly used as an additive for synthetic detergents, soap builder and bar soap builder and bar soap oil precipitation and blooming.
2. It has a strong emulsifying effect on lubricating oil and fat, can be used to adjust the pH value of buffered soap solution, softener for industrial water, leather premixing agent, etc.
3. Used as a dispersant for acid suspension in industry, drilling mud dispersant, and used as a stain remover in papermaking industry, etc.
Requirements
1. Appearance: white granular or powdery.
2. Package:25kg/50kg/1000kg/bag,or as buyer request
