    Humic acid

    Humic acid is a macromolecular organic substance that exists widely in nature and is widely used in various fields such as agriculture, forestry, animal husbandry, petroleum, chemical industry, building materials, medicine and health, and environmental protection


    [Structural formula]


    [Physical and chemical properties]


    [Preparation method] Graft modification of humic acid with acrylic acid, the result shows that the amount of substance HA:AA=1:1, the amount of initiator is 10%, the reaction temperature is 75℃, and the reaction time is 4h.


    (1) Complexing solubilization is the basic function of scale inhibitors, but HAS and Ca 2+ generate insoluble calcium humate precipitation, so its solubilization cannot be fully demonstrated by static scale inhibition


    (2) The effect of HAS lattice distortion is enhanced with the increase of HAS concentration, and the effect of lattice distortion is better reflected in high hardness water


    (3) HAS has a strong dispersing effect on CaCO 3 in water , and its dispersing ability is better than HEDP and HPMA under the same conditions


    (4) HAS has a certain synergistic effect with HEDP and HPMA, and a better treatment effect can be obtained when used in combination
