Calcium carbonate is commonly used in conjunction with kaolin in papermaking; it can increase the shining, whiteness, opacity, and ink absorption of paper. The shift from acidic to neutral sizing methods in the papermaking industry has greatly increased demand for calcium carbonate. Calcium carbonate is chiefly used as a surface coating in the neutral papermaking process, and is also used as a filler to cut expenses. It is further used as a buffering agent and to add structure. Thanks to its good dispersion and low viscosity, calcium carbonate can be used as a partial replacement for clay. It can effectively improve paper's whiteness and opacity, enhance smoothness and softness, improve ink absorption, and boost ink retention. When used in coatings, ultrafine heavy calcium carbonate offers better whiteness, ink absorption, and air permeability than kaolin. It is suitable for use in base and surface coatings used on white cardboard and copper printing paper, and increases corrosion resistance, durability, and strength. It can significantly enhance the whiteness and smoothness of paper, reduce production costs by lessening need for glue and whitener, and improve paper's printing performance.
