    Characteristics:

    HEDP is an organic phosphonic acid corrosion inhibitor and scale, with iron, copper, zinc and other metal ions to form a stable complex, to dissolve the surface of metal oxide.

    In the next 250 °C still play a good role in corrosion and scale inhibitors in high pH stability is still under difficult to hydrolysis, light and heat conditions in general difficult to break down.

    Acid, oxidation-resistant than other organic acid (salt) good.

    With metal ions in the water, in particular the formation of six calcium chelate ring, and thus be better and have the effect of scale soluble obvious effects are limited, and other water treatment agent using the compound has shown the desired synergy .

    HEDP solid belong to high-purity products, applies to the winter cold regions; particular, the electronics industry apply to the cleaner use of chemicals and additives day.

    The quality indicators in line with HG / T 3537-1999
