Calcium carbonate - polymer and inorganic matter
Polymer is a type of modifier that prevents calcium carbonate particles from agglomerating and agglomerating by directional adsorption on the surface of calcium carbonate to form a physical or chemical adsorption layer and give it charge characteristics to improve dispersibility.
Inorganic electrolytes are adsorbed on the surface of nano-calcium carbonate as modifiers, which can increase the value of the surface potential of nano-calcium carbonate. At the same time, the degree of wettability of the surface of nano-calcium carbonate in water is also enhanced, which prevents the aggregation of nano-calcium carbonate in water to a certain extent.
Common inorganic electrolyte modifiers include sodium aluminate, sodium silicate, alum, condensed phosphoric acid, etc.
