Because it has a special complexation function to metal ions, especially calcium, magnesium and some other alk Li-earth metal ions. Therefore, it is mainly used for boiler water as softener, cleaning agents in fiber industry, bleaching and dyeing industry, as well as flotation agents in mineral processing industry. With the continuous development of industrial production, the applications of SHMP has developed from water treatment, paper making, sugar extraction, food processing industries to smelting industry. Using sodium hexametaphosphate shmp and ingesting some additives to spray repair the steelmaking converter at a certain temperature and pressure can greatly extend the life of the converter and achieve obvious economic benefits.
Sodium hexametaphosphate 68% can be used as food quality improver, PH value regulator, metal ions chelating agent, adhesive and expansion agent in food processing industry. It is necessary to purchase the high quality food grade sodium hexametaphosphate, contact us for price now.
Sodium tripolyphosphate, sodium hexametaphosphate, sodium pyrophosphate are the commonly used inorganic dispersants. Sodium hexametaphosphate dispersing agent is an additive to improve the dispersion performance of solid of liquid materials. When solids are ground, the dispersing agent can be added to help the particles to pulverize, prevent the agglomeration of pulverized particles and keep the dispersion stable. The water-insoluble oily liquid can be dispersed into small liquid bead under high shear stirring. After the stirring is stopped, the oil layer will layered quickly under the action of interfacial tension. The addition of SHMP dispersing agent can make it form a stable emulsion after stirring.
The application of sodium hexametaphosphate in toothpaste can slow down the regeneration of dental calculus, whiten teeth and improve the stability of toothpaste during its shelf life.
Agentia for corrosion prevention, cement hardening accelerator, streptomycin purifying agent. Used as sedative in medicine industry. Used for rusting prevention of drilling pipe and controlling the viscosity of mud when drilling oil. It also has uses in fabric printing, tanning, papermaking, color film, soil analysis, radiochemistry, analytical chemistry and other fields.
