Physicochemical Property of Sodium Phosphate Dibasic powder

White powder, flake or granule. Easily soluble in water, its aqueous solution is alkaline; insoluble in alcohol.

Production methodprocess of Sodium Phosphate Dibasic powder

Add disodium phosphate dodecahydrate into the dissolving tank, heat and dissolve, add a small amount of industrial phosphoric acid, adjust pH8.8-9.0, solution temperature 80-85℃, pump to the metering tank, atomized by the sprayer, the atomizer selects the two-flow type of vapour spray nozzle, the steam pressure is 0.15-0.3Mpa, the atomizer vapour flow angle is 30° to the horizontal, the vapour-liquid ratio is 30°, the vapour-liquid ratio is 0.5-0.5Mpa.

Horizontal into 30 °, steam-liquid ratio (0.4 ~ 5): 1. hot stove gas inlet temperature 650 - 750 ° C. Drying can be parallel flow, can also be counter-current drying. Such as counter-current drying, the inlet temperature 620-650 ℃, the exit temperature 140-150 ℃. The finished product particle size of about 90μm accounted for 60%, moisture content <1%. Sodium Phosphate Dibasic powder is produced.
