Buy Sodium Tripolyphosphate Stpp Tech Grade
Sodium tripolyphosphate Detergent has three main functions:
1. Chelation of heavy metal ions: The heavy metal ion in water, combine with the detergent molecule in the catharsis process become insoluble metal salt, make catharsis ability reduces, lose effect completely even. STPP detergent can eliminate the negative effects of heavy metal ions. It has a strong chelation effect on heavy metal ions, which can be blocked to eliminate the adverse effects on washing. In addition, it can also capture the dirt contained in a variety of metal components, in the washing process to play a role in the dirt dissociation.
2. Descaling, emulsifying and dispersing of dirt: Sodium tripolyphosphate can expand and solubilize the protein in the dirt, and has the effect of degumming. It can promote the emulsification of fat and disperse solid dirt.
3. Effect of preventing agglomeration to the detergent: STPP chemical can keep detergent dry and granular, and prevent water absorption and caking. In addition, it has an alkaline buffering effect and is beneficial to the removal of ACID dirt.
