in daily washing water, there is usually hard metal ions, which will form insoluble metal salts with the active substances in soap or detergent to reduce the washing ability during washing process. So it is necessary to add something to detergents to make the metal ions contained in the washing water into harmless substances.
(1). The buffer function of sodium tripolyphosphate stpp has strong chelating effect on metal ions, which can eliminate the adverse effect on washing.
(2). In addition, it can captures the metal components contained in dirt and acts to dissociate the dirt during washing process.
(3).It has the effect of swelling and solubilizing the protein in dirt, as well as dissolving the gel.
(4). It can also promote the emulsification of fat and disperse solid dirt. (5). Meanwhile, it has the effect that prevent powder-detergent from agglomeration and keep it dry and granular.
Uses in the food industry:
STPP chemical, as water retention agent, quality improver, PH value regulator, metal chelating agent, can be widely used in dairy food, meat food, baked food, flour food, seasoning food, etc… It should be noted is that as food additive, it has strict requirements on the amount of use. Compared with industrial grade STPP, the food grade sodium tripolyphosphate has more stringent requirements and more inspection and monitoring programs in producing. The raw material for the production of STPP food grade must be food grade or genuine products, ordinary industrial grade products can't be used, such as, it must use genuine thermal phosphoric acid, not wet-processed type, even the orthophosphoric acid is food grade.
Other uses:
1.In ceramic industry, it can be used as ceramic degumming agent, water reducing agent.
2.Auxiliary agent of synthetic detergent.
3.Softener for industrial water.
4.Drilling mud dispersant.
5.Used in paper making industry as anti-oil agent.
6.Soap synergist and can prevent soap grease precipitation and frosting.
7.Sodium tripolyphosphate used in toothpaste can play the role of removing the the tooth stains.
8.It has strong emulsification effect on lubricating oil and fat.
9.Adjust the PH value of buffer soap.
10.It can be used as dispersing agent in the preparation of suspensions in dyeing auxiliaries, paints, kaolin, magnesia, calcium carbonate and other industries.
