Application:
Disodium Phosphate Dodecahydrate is used as a water-softening agent for boilers, buffering agents, solder, tanning agents, etc.
Disodium phosphate is used in conjunction with trisodium phosphate in many steam-boiler applications. It supplies the inventory of free phosphates to retard calcium scale formation. In water treatment, Disodium Phosphate retards calcium scale formation.
Disodium phosphorus is used for boiler soft agents, fabric, wood, and paper of flame retardants, and glaze medicine. Disodium Phosphate is also found in some detergents, cleaning agents, and dyeing with salt.
In printing and dyeing industries, Disodium phosphate is used as a hydrogen peroxide bleaching stabilizer, rayon packing (enhancement of silk strength and elasticity), and for manufacturing focal phosphorus sodium and other raw materials, as well as monosodium glutamate, erythromycin, penicillin, streptomycin, and sewage production, cultivating agent products, etc.
It is also used in electroplating and leather.
