Supply Sodium Phosphate Raw Materials powder Trisodium phosphate
Product Overview:
Trisodium phosphate (Na3P2O7) has the appearance of white granules and is mainly used in the manufacture of pharmaceuticals, pesticides, dyes, pigments and pharmaceutical intermediates. Trisodium phosphate is stable at room temperature and cannot react with oxidising agents or strong acids, but it will decompose when the temperature exceeds 120℃. Therefore, trisodium phosphate should be stored in a cool and ventilated place. Store in a dry warehouse, away from fire and heat source.
The storehouse requires ventilation, dryness, absence of water and protection from rain, and no direct sunlight. It should be stored separately from oxidising agents and acids, and should never be mixed.

Sodium Phosphate Usage and Synthesis.
In the industrial field, trisodium phosphate is mainly used as cleaning agent, corrosion inhibitor, scale inhibitor and dust remover. It can remove the dirt and sediments on the surface of the equipment, and at the same time play the role of rust prevention; in the field of chemical industry, iron and steel, as a pickling corrosion inhibitor, effectively inhibit the acid corrosion of the equipment; as a scale inhibitor, prevent the formation of scale, widely used in the field of water treatment; in addition, it can be used in the cleaning agent, corrosion inhibitor and dust remover. In chemical industry, steel and other fields, as a pickling corrosion inhibitor, effectively inhibit the corrosion of acid on the equipment; as a scale inhibitor, to prevent the formation of scale, widely used in the field of water treatment; in addition, it can also be used to manufacture high-efficiency dust removing agent, to the dust in the air Adsorption and removal of airborne dust.
In the field of medicine, trisodium phosphate can be used as raw material of medicine, pharmaceutical auxiliary and disinfectant of medical equipment. It can be used to synthesise some drugs, such as antibiotics, antiviral drugs, etc.; in the pharmaceutical process, it is used as a pharmaceutical auxiliary to improve the stability and efficacy of drugs; In addition, it can also be used as a medical device disinfectant to kill bacteria and viruses and ensure the safe use of medical devices.
In the food field, trisodium phosphate is used as food additive, processing aid and flavouring. It can play the role of antiseptic, antioxidant, and improve the taste and quality of food; trisodium phosphate can also be made into a variety of flavourings, such as phosphate, pyrophosphate and so on. It is widely used in cooking and food processing.
Uses of Sodium Phosphate.
It is used as water softener and detergent, boiler anti-scaling agent, colour fixing agent in printing and dyeing, mercerizing enhancement agent for fabrics, metal corrosion inhibitor or rust preventive agent. It is used as flux and decolourant in enamel industry. It is used as degreasing agent and degumming agent in tanning industry.
Work quality improver, has the effect of improving the complex metal ions, pH value, increasing ionic strength of food, thus improving the adhesion and water retention of food. China's regulations can be used in cheese, the maximum use of 5g/kg; in western ham, meat, fish, shrimp and crab in the maximum use of 3.0g/kg; in canned food, fruit juice, beverages and dairy products in the maximum use of 0.5g/kg.
In the food industry as a water retention agent, used in canned food, fruit juice drinks, dairy products, meat products, cheese and beverages. It is used as water softener and detergent in chemical, textile, printing and dyeing, papermaking, power generation, etc. It is used as anti-scaling agent in boiler, water softener in paper dyeing, pH buffer in adhesive for waxed paper, colour fixing agent in printing and dyeing, mercerizing enhancement agent in fabrics, and anti-brittle agent in thread making.
It is used in metallurgical industry as a chemical degreasing and decontamination, and as an excellent accelerator in photographic developing solution. Dental cleaner and bottle detergent. Coagulant for rubber emulsion. Sugar purifier.
Preparation method of Sodium Phosphate.
Product method of Bulk Sodium Phosphate Powder.
Spray drying method of trisodium phosphate dodecahydrate crystals added to the dissolution tank with l0% to 15% of water, heated to 85 ~ 95 ℃, stirring dissolution, solution purification, the refined solution with a pump to the metering tank, atomized by the sprayer, atomizer selection of the two-flow type air nozzle, in the atomization of the steam guide angle and the level of 30 °, the atomization of the steam pressure of 0.15 ~ 0.3Mpa, the inlet temperature 650 ~ 750 ℃, the outlet temperature of 140 ~ 170 ℃ for spray drying to produce anhydrous trisodium phosphate finished products. 750 ℃, the outlet temperature of 140 ~ 170 ℃ for spray drying, anhydrous trisodium phosphate product.
