Industrial Grade Sewage Treatment Chemicals Trisodium Phosphate for Surface Treatment
Product Introduction:
Sodium phosphate, with the chemical formula Na3PO4, is a type of phosphate. It is prone to deliquescence and weathering in dry air, producing sodium dihydrogen phosphate and sodium bicarbonate. Almost completely decomposed into disodium hydrogen phosphate and sodium hydroxide in water. Used in the electroplating industry to prepare surface treatment degreasing solutions and alkaline detergents for unpolished parts. In synthetic detergent formulations, due to their high alkalinity, they are only used for strong alkaline cleaning agent formulations, such as car cleaners, floor cleaners, metal cleaners, etc.

Product Usage:
1. A work quality improver has the effect of increasing the chelating metal ions, pH value, and ionic strength of food, thereby improving the adhesion and water holding capacity of food. According to Chinese regulations, it can be used for cheese with a maximum usage of 5g/kg; The maximum dosage for Western style ham, meat, fish, shrimp, and crab is 3.0g/kg; The maximum usage amount in canned food, juice, beverages, and dairy products is 0.5g/kg.
2. Used as a water softener and detergent in industries such as chemical, textile, printing and dyeing, papermaking, and power generation, boiler anti scaling agent, water softener in paper dyeing, pH buffering agent for adhesives used in wax paper production, fixing agent during printing and dyeing, silk gloss enhancer for fabrics, and anti brittleness agent for production lines. Metallurgical industry is used as a chemical degreasing and cleaning agent, and as an excellent promoter in photographic development solutions. Teeth cleaning agents and bottle cleaning detergents. Coagulant for rubber milk. Sugar juice purifier. Phosphates play a role in improving the quality of food processing, such as maintaining the water holding capacity of meat and enhancing cohesion in meat products, in order to reduce the loss of nutrients in meat and preserve its tenderness. It is also used as an emulsifier, nutritional supplement, and quality improver in food processing. It is a raw material for preparing alkaline water for noodles, and is also used for refining sugar and manufacturing alpha starch. It is also used as a detergent for food bottles, cans, etc.
3. Solid trisodium phosphate (TSP) belongs to the category of strong alkali and weak acid salts, with strong alkalinity and high solubility. It has stable chemical properties and can be stored for a long time. Adding TSP instead of NaOH to the spray water of the containment spray system (EAS) can adjust the pH value of the spray liquid, effectively remove iodine gas released from the leaked cooling water into the containment, avoid harm to workers caused by strong alkali, and is easy to clean up after accidents.
