良好的产品STPP钠tyipolyphosphate detergen

Sodium tyipolyphosphate Chemical formula Na5P3O10 Molecular weight 367.86 Properties White gpowder, melting point at 622,soluble in water.It has got salient chelating capacity to metal ions of Ca and Mg etc.And can soften hard water to make suspension into solution,alikaline,without causticity.It is a surfactant,and has got outstanding emulsification to lubricants an fat.It has different bulk density,i.e. low density 0.35∼0.5g/cm3,medium density 0.51∼0.65g/cm3 and high density 0.66∼0.9g/cm3.This product has two crystalline forms,namely phase (high temperature phase) and phase (low temperature phase).The chemical properties of the two phase are the same,and the difference between them lies in the thermostability, hygroscopicity,solubility and hydration heat when dissolving. Application Used as buffering agent,emulsifying agent,nutrition intensifier and quality improver.Regulate PH value and intensify water retentivity of meat,intensify.The machining character of noodles products and improve its quality,as quality improver in canned products,fruit juice drinks and dairy products etc,prevent fruit from changing color after machining,emulsifier for cheese,additive for soy and soybean milk,also as detergent for egg,etc. Packing 25kg or 50kg net in plastic-woven sack with inner polythene film bag.Store in a ventilated,dry place.
