Sodium Hexametaphosphate Powder Usage and Synthesis.

For some metal ions (such as calcium, magnesium, etc.) have the ability to generate soluble complexes, so it can be used to soften water.

With lead, silver and other ions will also generate precipitates, these precipitates dissolved in excess of sodium hexametaphosphate solution to form complexes, barium salt can also be generated with sodium hexametaphosphate complexes.

It is used as high efficient water softener for power station, boiler water for rolling stock, auxiliary agent for detergent, agent for controlling or preventing corrosion, cement hardening accelerator, streptomycin purifying agent, cleaning agent for fiber industry and bleaching and dyeing industry. It is used as sedative in medicine, preservative, stabilizer and juice precipitant in food industry.

In the petroleum industry, it is used for antirust of drilling pipe and controlling the viscosity of mud in oil drilling. It is also used in fabric printing and dyeing, tanning, papermaking, color film, soil analysis, radiochemistry and analytical chemistry.

China GB2760-1996 stipulates that sodium hexametaphosphate is allowed to be used as a food additive (water retention agent), which can be used in canned food, juice drinks, dairy products, soybean products; it is also used as a dispersant for dyes and a water treatment agent.

Uses of Sodium Hexametaphosphate.

Sodium hexametaphosphate can be used in meat products, fish sausage, ham, etc., which can improve water-holding capacity, increase adhesion and prevent fat oxidation; it can be used in soybean paste and soy sauce to prevent discoloration, increase viscosity, shorten fermentation period and regulate taste;

It can be used in fruit drinks and refreshing drinks to improve juice yield, increase viscosity and inhibit the decomposition of vitamin C. It can be used in ice cream to improve expansion capacity, increase volume, enhance emulsification to prevent the destruction of paste, and improve the taste and color; it can be used in dairy products and beverages to prevent gel precipitation; it can be added into beer to clarify the liquor and prevent turbidity;

Used in beans, fruits and vegetables canning, it can stabilize natural pigment and protect the color of food. In addition, sodium hexametaphosphate aqueous solution can be sprayed on cured meat to improve the antiseptic property.

Used as water softener for boiler water and industrial water (including water for dyestuff production, titanium dioxide production, printing and dyeing pulp and dyeing water, cleaning color film prints, as well as water for chemical industry, pharmaceuticals, reagents, etc.), water treatment agent for industrial circulating coolant; also used as corrosion inhibitor, flotation agent, dispersing agent, high temperature bonding agent, dyeing auxiliaries, metal surface treatment, antirust agent, detergent auxiliaries, cement hardening promoter. Cement hardening promoter.

Copperplate paper production is used as pulp diffusion agent to improve penetration. It is also used in detergents and chemical fibers to remove iron ions from the pulp. In the petroleum industry, it is used to prevent corrosion of drilling pipes and to regulate the viscosity of mud when controlling oil drilling.

Characteristic of Sodium Hexametaphosphate.

This product is white crystalline powder, specific gravity is 2.484 (20 ℃), easily soluble in water but insoluble in organic solvents has a strong hygroscopic function. It has remarkable chelating ability for metal ions Ca and Mg.

Product Method of Bulk Sodium Hexametaphosphate Powder.

Sodium dihydrogen phosphate method will be liquid yellow phosphorus sprayed into the combustion chamber combustion, and air oxidation to generate phosphorus pentoxide, by hydration to generate phosphoric acid, dilute phosphoric acid added to the reactor, under stirring slowly add caustic soda solution at 80 ~ 100 ℃ to neutralize the reaction, so that the Ph value of 4 ~ 4.4, the generation of sodium dihydrogen phosphate solution, add alkali sulphide for purification, to remove impurities such as arsenic, heavy metals and other impurities, filtration, will be filtered, the filtrate through the The filtrate is dehydrated and melted at 750～850℃ for 20min to produce molten sodium hexametaphosphate, then indirectly cooled by cooling water to quench the tablet and crushed to produce edible sodium hexametaphosphate.
