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. It is almost completely decomposed into disodium hydrogen phosphate and sodium hydroxide in water. 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 Usage
Trisodium phosphate is an important inorganic compound widely used in many fields such as industry, food, medicine, and agriculture.
In the industrial field, trisodium phosphate is mainly used as a cleaning agent, which can remove dirt and sediments on the surface of equipment. It also has the functions of corrosion inhibition, scale inhibition and dust removal. In the food field, it can be used as a food additive to play a preservative and antioxidant role. It can also be used as a food processing aid to improve the taste and quality of food. In the field of medicine, trisodium phosphate can be used as a raw material for the synthesis of some drugs, such as antibiotics, antiviral drugs, etc. It can also be used as a pharmaceutical auxiliary and a disinfectant for medical equipment. In the agricultural field, it can be used as a fertilizer additive to improve fertilizer utilization and plant absorption. It can also be used as a pesticide auxiliary and soil conditioner.
In addition, trisodium phosphate is also widely used in the electronics industry, environmental protection fields and scientific research fields. In the electronics industry, it is used to manufacture high-purity phosphates; in the field of environmental protection, it is used to treat industrial wastewater and domestic sewage; in the field of scientific research, as a common inorganic salt, it is often used as experimental reagents and research tools.
Precautions for trisodium phosphate include:
Irritation and protection: Trisodium phosphate is an irritant. Avoid direct contact with skin and eyes. Wear protective gloves, goggles and protective clothing.
Hygroscopicity and storage: Trisodium phosphate is easily hygroscopic and needs to be stored in a dry, ventilated place, kept sealed, and protected from moisture and high temperatures.
Alkaline properties: Trisodium phosphate is an alkaline substance. Be careful not to mix it with acidic substances to avoid generating harmful gases or reducing the effect.
Dissolution and stirring: Trisodium phosphate dissolves slowly and needs to be fully stirred or soaked to ensure complete dissolution.
High temperature decomposition: Trisodium phosphate is easy to decompose at high temperatures. Pay attention to temperature control when using it and avoid prolonged high temperature heating.
Concentration and usage: In specific application areas, such as textile softeners, pay attention to control the concentration and usage of trisodium phosphate to avoid damage caused by excessive levels.
