Product Description

Product description


High-solids heavy calcium carbonate is used in papermaking. Because of the less moisture retained, the water filtration is good, and the paper machine has better running performance. Because of the good grain size composition and morphology of heavy calcium carbonate, it is beneficial to paper. The combination of fibers and the strength of the paper can also improve the whiteness, opacity, gloss, smoothness, water absorption of the paper, reduce the viscosity of the paper coating and increase the strength of the paper.
