Comparison of sodium hexametaphosphate and trisodium phosphate

Sodium hmetaphosphate is used as soft water agent for cooling water treatment in power stations, rolling stock, boilers and chemical fertilizer plants, additives for detergents, agents for controlling or preventing corrosion, cement hardening enhancer, streptomycin purification agent, cleaning agent for fiber industry and bleaching industry. Used in mineral processing industry as flotation agent. It is used in medicine to prevent rust in drilling pipes and to control the viscosity of swelling slurry during oil drilling. It is also used in textile dyeing, leather tanning, paper making, color film, soil analysis, radiochemistry, analytical chemistry and other departments.

Trisodium phosphate is mainly used in synthetic detergent as an additive, soap synergist and to prevent bar soap oil precipitation and frosting. It has a strong emulsifying effect on lubricating oil and oil, and can be used to adjust the PH value of buffer soap liquid, industrial water softener, tannery pre-tanning agent, dyeing assistant, paint, kaolin, magnesium oxide, calcium carbonate and other industries to use suspension as dispersant, drilling mud dispersant, and paper industry as anti-oil agent.
