Sodium tripolyphosphate is an inorganic substance with chemical formula Na5P3O10. It is a kind of amorphous water-soluble linear polyphosphate. It is used as water retention agent, quality improver, pH regulator and metal chelator
Main Application:
Industrial use Used as detergent, auxiliary, also used in petroleum, metallurgy, mining, paper making, water treatment, etc.. Mainly used as synthetic detergent additives, synergist for soap and soap to prevent a fat separation and bloom. It has a strong emulsifying action on lubricating oils and fats and can be used to regulate the pH of buffer soap solutions. Water softener for industrial water. Tanning agent. Dyeing assistants. Paint, kaolin, Magnesium Oxide, calcium carbonate and other industries in the preparation of suspension as a dispersant. Drilling mud dispersant. The paper industry is used as an anti oil agent. Canned food, for the food industry in fruit juices, dairy products, soy milk and other quality improvement agent, water retention agent. Mainly for canned ham tender, broad beans in the skin softening, it can also be used as a thickening agent and softener.
