    Product Description

    Sodium hexametaphosphate(SHMP) is an inorganic substance with molecular formula (NaPO3) 6. It is a white powder crystal, or a colorless transparent glass sheet or block solid. Soluble in water, insoluble in organic solvents. It has strong hygroscopicity. When exposed to the air, it can gradually absorb water and form a mucilage. It can form soluble complexes with calcium, magnesium and other metal ions. It is widely used in food and industrial fields.

    Sodium hexametaphosphate is a viscous substance after water absorption, which is closely related to the nature of hexametaphosphate itself, the molecular formula of sodium hexametaphosphate belongs to a polyphosphate of variable composition, the anion of sodium hexametaphosphate has a high molecular weight, and generally contains the number of PO3 genes up to 20-100, and forms a long chain.

    Product characteristics

    non-toxic and harmless

    Slow down the hydration reaction of cement

    Excellent dispersion stability

    It is highly acidic in water

    Application

    The application of sodium hexametaphosphate in concrete is mainly to add sodium hexametaphosphate to concrete admixture, which can make concrete workability good and no bleeding, so that the later working performance of concrete is guaranteed. Sodium hmetaphosphate concrete admixtures can improve the mechanical properties and construction performance of machine-made sand concrete with high dry mud and stone powder content, complex calcium ions, increase its solubility, and thus reduce the doubt effect.

    The addition of sodium hmetaphosphate is a kind of admixture that can delay the hydration reaction of cement, thus extending the setting time of concrete, keeping the plasticity of newly mixed concrete in a long time, facilitating the pouring, improving the construction efficiency, and not causing adverse effects on the performance of concrete in the later stage.

    Sodium hempetaphosphate is a kind of compound with good corrosion inhibition and corrosion prevention and dispersion stability, which is mainly used in the fields of detergent, water treatment agent and metal rust prevention. It is used more and more widely in modern chemical, daily chemical and construction industries and plays an important role.
