    Product Description

    Boric acid is an inorganic compound with the formula H3BO3. Boric acid is essentially the hydrate of boron oxide. It is a colorless scaly oblique crystal or white powder with pearl-luster, odorless, and smooth to the touch. The taste is slightly sour and sweet. Boric acid dissolves in water and forms a corresponding acid-base equilibrium, H3BO3 H+ + B(OH)4-. Boric acid has a certain acidity, it can react with a part of the hydroxide in concrete to generate the corresponding borate, which plays a role in controlling the concrete gel solidification process.

    Product characteristics

    Improve concrete durability

    Accelerate concrete gel setting

    Slow down the shrinkage of concrete

    Promote the early strength development of concrete

    Application

    Boric acid can accelerate the solidification process of concrete, slow down the shrinkage rate of concrete, and promote the development of early strength of concrete.

    Effect of boric acid on concrete properties

    1. Boric acid reacts with the hydroxide in the concrete to form a borate, which accelerates the concrete gel solidification process and improves the strength and durability of the concrete.

    2. Boric acid can cause silicate hydration reactions in concrete, thus promoting the early strength development of concrete.

    3. Boric acid can slow down the shrinkage rate of concrete, thus reducing the risk of cracking of concrete.

    4. Boric acid can improve the impermeability and frost resistance of concrete, thus improving the durability of concrete.

    Glass and fiberglass

    Boric acid can improve the heat resistance and transparency of glass, increase the mechanical strength, and shorten the melting time.

    Enamel, ceramic

    Boric acid prevents cracking and deglazing and improves the luster and fastness of products.

    metallurgy

    Used as an additive and cosolvent in the production of boron steel. Boric acid can prevent the surface oxidation of metal welding, brazing, and casing welding.

    Chemical industry

    Used in the production of various borates, such as sodium borohydride, ammonium hydrogen borate, cadmium borotungstate, potassium borohydride, and so on.

    Package & Storage

    Package: 25kg bag and 1000kg ton bag

    Storage: Keep in a cool, dry, dark location in a tightly sealed container or cylinder.

    The shelf life is two year (24 months)

    Technology Service

    Adding proper boric acid in the process of concrete production and use can improve the performance and durability of concrete, and it is worth popularizing and applying.
