Product Introduction:

Sodium polyphosphate, likewise called sodium hexametaphosphate, is an colorless to white glazed block, flake or white powder. Soluble in water, insoluble in organic solvents. It has strong hygroscopicity, and when exposed to the air, it can slowly soak up water and end up being a sticky material.

Salt polyphosphate and calcium, magnesium and other metal ions can develop soluble facilities. It has a wide variety of uses in both food as well as industrial fields.

This product is mainly made use of as a water softener in coloring or post-treatment. It can record calcium ions and also magnesium ions from the precipitation of insoluble calcium soap, magnesium soap or calcium dye and also magnesium color, as well as re-dissolve the precipitate.

Product Usage:

As Water Softener

Salt polyphosphate is generally used as water softener for central heating boiler water and industrial water (consisting of color manufacturing water, titanium dioxide production water, printing as well as coloring slurry and dyeing water, along with chemical water, medicine, reagent production water, and so on).

Salt polyphosphate is rarely utilized alone, as well as is generally utilized in combination with pyrophosphate as well as metaphosphate. Mainly used for ham, sausage, surimi and the like as a tissue modifier for water retention, tenderization and softening of old and residual meat.

Used in Food:

The application of food-grade sodium polyphosphate in food processing is growing rapidly, mainly as water retention agent, quality improver, PH regulator, metal ion chelating agent, fermentation leavening agent and other purposes.

Stop formation of canned crabs, pectin solubilizer, etc. Used in canned beans, fruits and vegetables, it can stabilize natural pigments and protect the color of food. Used in canned meats to emulsify fat and maintain a uniform texture.

When used in meat food, it can improve the water holding capacity and prevent the fat in the meat from deteriorating.

When contributed to beer, it can clear up the liquor as well as avoid turbidity.

Other Uses:

Salt polyphosphate is also utilized as corrosion inhibitor, flotation representative, dispersant, heat binder, dyeing auxiliary, metal surface treatment, corrosion prevention, detergent auxiliary, cement hardening accelerator.

Layered paper manufacturing is utilized as a slurry diffusing representative to improve infiltration. Additionally, it is likewise used in washing utensils and also chemical fibers to get rid of iron ions in pulp.

In the oil market, it is made use of for corrosion avoidance of drilling pipelines and also to control the viscosity of mud throughout oil exploration.
