Product application:
Sodium tripolyphosphate, also known as trisodium phosphate, is a common inorganic compound and has extensive applications in fields such as food, water treatment, detergents, and agriculture. The following are the main functions and applications of sodium tripolyphosphate:
1. Food industry: In the food industry, sodium tripolyphosphate is mainly used as a quality improver, moisture retainer, emulsifier, buffer, water softener and dispersant, etc. It can enhance the water retention of food, prevent meat from discoloring or losing its flavor during storage and processing, and extend its shelf life. In addition, it is also used to enhance the texture of foods such as noodles and bread and extend their shelf life.
2. Water Treatment: In the field of water treatment, sodium tripolyphosphate is used as a corrosion inhibitor and water softener. It can prevent metal ions in water from corroding pipes and equipment, and combine with heavy metals in water to form insoluble precipitates, thereby purifying water quality.
3. Detergents and cleaning agents: In detergents and cleaning agents, sodium tripolyphosphate, as an additive, can significantly enhance the washing effect, prevent the formation of scale, and maintain the cleaning effect for a longer time.
4. Agriculture and Horticulture: In agriculture and horticulture, sodium tripolyphosphate can be used as a phosphate fertilizer to provide phosphorus for plants and promote their growth and development. Meanwhile, it can also form stable phosphates in the soil, prevent the loss of phosphate fertilizers and improve the utilization rate of fertilizers.
5. Other applications: Sodium tripolyphosphate is also used in the pharmaceutical industry as a dispersant to help drugs disperse evenly, enhancing their solubility and absorption rate. In industries such as leather tanning, dyeing and coating, it can be used as a dispersant, emulsifier, etc.
