2P-725 : Chemical and mechano-chemical hyderophobic surface modification of calcite obtained by gypsum process

The calcium carbonate powder obtained by gypsum mineral carbonation process was modified by direct blending and mechano-chemical methods in the media of organic solvent. Several materials were used as modifiers for the purpose of positively increased hydrophobicity and advanced functionality of calcium carbonate surface. The surface characteristic parameters of modified calcium carbonate showed better enhanced functionality demand for as fillers of raw polymer materials.
