Product name: Sodium tripoly phosphate is a kind of amorphous water-soluble linear polyphosphate
Alias: Pentaphosphate
English name:sodium tripolyphosphate
Molecular formula:Na5P3O10
Molecular weight:367.86（According to 1985 International Atomic Weight）
Performance characteristics: white powder or powder, apparent density 0.35-0.90g/cm3, melting point 622 degrees Celsius. soluble in water. The aqueous solution is alkaline, and the pH of 1% aqueous solution is 9.7. It is gradually hydrolyzed into phosphite in water and has a good ability to complex metal ions. It can complex with calcium, magnesium, iron and other metal ions to form soluble complexes. Can soften hard water. As an inorganic surfactant, it has the properties of a certain organic surfactant.

【Use】
Uses: Used as detergent additives, and can also be used in petroleum, metallurgy, mining, papermaking, water treatment, etc. It is mainly used as an auxiliary agent of synthetic detergent, used as a soap synergist and to prevent the precipitation and blooming of bar soap grease. It has a strong emulsification effect on lubricating oil and fat, and can be used to adjust the pH value of buffer soap. Water softener for industrial water. Tanning --- agent. Dyeing auxiliary. It is used as a dispersant when preparing suspension in paint, kaolin, magnesium oxide, calcium carbonate and other industries. Drilling mud dispersant. Used as an anti-greasy agent in the paper industry. In the food industry, it is used as a quality improver and moisture retention agent for canned food, fruit juice drinks, dairy products, soy milk, etc. Mainly used for the tenderization of canned ham, canned broad beans soften the skin of soybeans, and can also be used as a softener and thickener. It is easily soluble in water and has significant chelating ability to metal ions such as calcium and magnesium. It can soften hard water and make it suspended. The liquid turns into a solution, which is weakly alkaline, non-corrosive, and is an inorganic surface
