    Sodium Tripolyphosphate Raw Materials Sodium Tripolyphosphate Powder Details

    Sodium Tripolyphosphate Powder Usage and Synthesis.

    Sodium tripolyphosphate is a widely used additive in detergent, textile, water softening, boiler descaling, drilling, metal beneficiation and other fields. It has good properties of emulsification, synergism, water softening and pH adjustment. At present, some new methods of producing sodium tripolyphosphate have been studied. The performance characteristics of sodium tripolyphosphate include white granular or powder, density 0.35-0.90g/cm3, melting point 622℃, soluble in water, aqueous solution is alkaline.

    Sodium Tripolyphosphate Powder

    Uses of Sodium Tripolyphosphate.

    Sodium tripolyphosphate is used in detergents, as an auxiliary, soap synergist and prevent bar soap crystallization and frosting, industrial water softener, tanning pre-tanning agent, dyeing auxiliaries, oil well digging mud control agent, oil stain prevention agent for paper making, effective dispersing agent for the treatment of suspensions in paints, kaolin, magnesium oxide, calcium carbonate and so on. Edible grade sodium tripolyphosphate can be used as food improver for various fish and meat products, clarifying agent for beverages.

    It can be used as food improver for fish and meat products, clarifying agent for beverages. It can also be used as food improver to increase the complexing metal ions, pH value and ionic strength of food products, thus improving the adhesion and water retention of food products. China's regulations can be used in dairy products, Chemicalbook products, poultry products, ice cream and instant noodles, the maximum use of 5.0g/kg; in canned food, fruit juice (flavor) drinks and plant protein drinks, the maximum use of 1.0g/kg.

    It is used as high efficient water softener for cooling water treatment in power stations, rolling stock, boilers and fertilizer plants. It has strong ability to complex Ca2+, 19.5g of calcium can be complexed per 100g, and due to the chelating effect and adsorption and dispersion of SHMP, it destroys the normal growth process of calcium phosphate crystals, and prevents the formation of calcium phosphate scale. The dosage is 0.5mg/L, and the rate of preventing scale formation is 95%~100%.

    Sodium Tripolyphosphate

    Preparation of Bulk Sodium Tripolyphosphate Powder.

    Sodium tripolyphosphate is traditionally prepared by neutralizing hot phosphoric acid with a soda ash suspension with a mass fraction of H3PO4 of 75% to produce a neutralized slurry with Na/P of 5:3, which is held at 70°C to 90°C; after which the obtained slurry is sprayed into a polymerization furnace to dehydrate at high temperature and condense into sodium tripolyphosphate at about 400°C.
