Product Description
Sodium phosphate, with the chemical formula Na3PO4, is a phosphate. It easily deliquesces and weathers in dry air, producing sodium dihydrogen phosphate and sodium bicarbonate. In the electroplating industry, it is used to prepare surface treatment degreasing liquid and alkaline detergent for unpolished parts. In synthetic detergent formulas, due to their high alkalinity, they are only used in strongly alkaline cleaning agent formulas, such as car cleaners, floor cleaners, metal cleaners, etc.
Product Application
Food field
1. As a quality improver, it can improve the complex metal ions, pH value, ionic strength, etc. of food, thus improving the binding force and water retention of food. China stipulates that it can be used in cheese, with a maximum usage of 5g/kg; in Western-style ham, meat, fish, shrimp and crab, the maximum usage is 3.0g/kg; in cans, juices, beverages and dairy products, the maximum usage is 0.5g /kg.
2. Used as analytical reagents and water softeners, and also used for the purification of sugar.
