Sodium tripolyphosphate(STPP), also known as sodium triphosphate, pentasodium triphosphate is a kind of amorphous water-soluble linear polyphosphate in terms of its chemical structure. Sodium tripolyphosphate formula is Na5P3O10 and the molecular weight is 367.86. In appearance, it is white or colorless crystals, which flows well, dissolves in water easily. The aqueous solution is alkaline, the PH value of 1% aqueous solution is 7.9. STPP chemical is a widely used phosphate chemical, which can be divided into food grade and industrial grade sodium tripolyphosphate 94% depends on the uses. Both the two types, Chemate can manufacture and supply. Inquiry us to tell us your requirements now, quotation will be sent to you very quickly.
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.
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.
Double-layer bags lined with polyethylene film are used as inner packaging and plastic woven bags are used as outer packaging, with a net content of 25kg per bag.
