Trisodium Phosphate powder Usage and Synthesis.

Trisodium phosphate is an inorganic compound with a wide range of applications. In the thermal power industry, trisodium phosphate is often used as a boiler scale inhibitor to prevent scale formation in boilers.

In the wastewater treatment industry, trisodium phosphate is used to treat wastewater and remove heavy metal ions from the water. In addition, trisodium phosphate is widely used in industries such as cosmetic additives, agriculture, printed circuit board industry and battery materials.

When using trisodium phosphate as a boiler scale inhibitor, there are some issues to be aware of. For example, trisodium phosphate can undergo a reversible hydrolysis reaction, so attention needs to be paid to the effect of its hydrolysis products on the boiler.

In addition, if the boiler pot water is not suitable for the application of phosphate scale inhibitors and other scale inhibitors are used, the residual amount of other scale inhibitors in the pot water should be in accordance with the indicators specified by the pharmaceutical manufacturer.

Uses of Trisodium Phosphate powder.

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 and other industries, boiler anti-scaling agent, water softener in paper dyeing, pH buffer in the production of waxed paper adhesive, color fixing agent in printing and dyeing, mercerizing enhancement agent in fabrics, and antifragile agent in thread making. Used in metallurgical industry as chemical degreasing and decontamination, used as excellent accelerator in photographic developing solution.

Dental cleaner and bottle detergent. Coagulant for rubber emulsion. Sugar juice purifying agent.

Solid trisodium phosphate (TSP) belongs to strong alkali and weak acid salt, with strong alkaline and high solubility, stable chemical properties, can be stored for a long time, in the containment spray system (EAS) of the spray water add TSP instead of NaOH, can adjust the pH value of the spray liquid, effectively remove the iodine gas from the leakage of the coolant water released to the containment, to avoid the injury of the staff of the strong alkali, easy to clean up after the accident. It is easy to clean up after the accident.

Characteristic of Trisodium Phosphate powder.

Colorless to white crystal or crystalline powder, anhydrous or containing 1 to 12 molecules of water of crystallization, odorless. Dodecahydrate melting point 73.4 ℃, relative density d20201.62.

Heated to 55 ~ 65 ° C into ten water, heated to 60 ~ 100 ° C into six water, heated to more than 100 ° C into a water, heated to more than 212 ° C into anhydrous. Soluble in water (28.3g/100mL), insoluble in ethanol. It is easy to deliquesce and weather in dry air, generating sodium dihydrogen phosphate and sodium bicarbonate.

In water, it is almost completely decomposed into disodium hydrogen phosphate and sodium hydroxide, and the pH value of 1% aqueous solution is 11.5～12.1. Oral LD50 of groundhog is＞2g/kg, ADl0～70mg/kg (FAO/WHO, 1994).

Product Method of Bulk Trisodium 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 vapor pressure of 0.15 ~ 0.3Mpa, the inlet temperature of 650 ~ 750 ℃, the outlet temperature of 140 ~ 170 ℃ under the spray drying to produce anhydrous trisodium phosphate finished products. 750 ℃, the outlet temperature of 140 ~ 170 ℃ for spray drying, anhydrous trisodium phosphate product.
