Sodium hexameta phosphate (SHMP) is widely used in paper production,
textile, dyeing, petroleum, chemistry, metallurgy and construction
materials etc, as water softener, flotation selecting agent, disperser
and high temperature adhesive; In food industry it used as an additive,
nourishing agent, quality improver, PH regulator, metal ions chelating
agent, adhesive and levening agent etc.
Sodium
salt is the largest production and most consumption products in fine
phosphorus chemical products, and sodium hexameta phosphate is the
market largest use amount of function of phosphate.
It is white
powder, soluble in water but insoluble in organic solvent; It may form
soluble chelates with ions of Ca, Ba, Mg, Cu, Fe etc. and is a good
water treatment chemical.
In the food industry, sodium hexameta
phosphate used as food quality improver, pH regulator, metal ions
chelating agent, adhesive agent and expansive agent. Sodium hexameta
phosphate for meat, fish intestinal and ham can improve holding water,
increase knot and prevent fat oxidation; when for soy sauce it can
prevent color, increase sticky, shorten fermentation period and
regulation taste; it can improve out juice rate and viscosity, inhibit
vitamin c decomposition when used in fruit beverage and cool beverage;
this also improve expansion capacity, increases volume, enhance emulsion
role and prevent cream body damage for ice cream; it prevent dairy
products and beverage from gel precipitation; add it to beer can clarify
wine, prevent pollution; as for beans, canned fruits and vegetables, it
stabilize natural pigment and keep food color; it improves corrosion
resistance when sprayed on the pickled meat.
Application in
mineral processing and oil industry, sodium hexameta phosphate is a
commonly used inhibitors of flotation. It mainly used to inhibit silica
and silicate minerals, and carbonate minerals such as calcite,
limestone. In addition, sodium hexameta phosphate also play the role of
dispersant in flotation. In the nickel ore flotation process, after
hauling mud cover on the surface of pentlandite, this is very negative
to the flotation process. So, add a certain amount of this product is
very favorable to pentlandite flotation recovery. Because the add of
sodium hexametaphosphate makes flotation pulp disperse and reduce the
surface covering of the serpentine in pentlandite.
In the oil
industry, it as a drilling mud additives can avoid polyvalent metal ions
precipitate, improve the ability of mud salt resistance and reduce mud
water loss.
Hexametaphosphate applied to fiber industry can
inhibit the generation of metal SOAP in the refining process; prevent
the decomposition of hydrogen peroxide in the bleaching process; it can
prevent color changes in dyeing; in paper making, the mix of sodium
hexametaphosphate and sulfonation of benzene formaldehyde can be used to
steel paper coating dispersant; etc. If you have interest to s odium
