Full Article. Improving Paper Mechanical Properties Using Silica-modified Ground Calcium Carbonate as Filler. Ana F. Lourenço, a José A. F. Gamelas, a, * João Sequeira, a Paulo J. Ferreira, a, * and José L. Velho b The ability to increase the filler content of paper without significantly sacing its mechanical strength is of high interest for papermakers.

The resulting calcium sulfite collects at the base of the absorber and compressed air is blown into this residue. The calcium sulfite reacts with the air to form calcium sulfate (gypsum), used to make, for example, plaster board and cement. Very fine and pure calcium carbonate is used as filler in plastics and paper.

cium carbonates (PCCs) and wet and dry ground calcium carbo­ nates (GCCs). These commercial calcium carbonate fillers were selected to cover a wide range of particle diameter and shape. The properties of fiber-loaded handsheets, at 25% filler level, were compared to that of five commercial calcium carbonate

The laboratory prepared calcium carbonate fillers from both limestone and waste marble as cheap resources were applied in paper handsheets. Commercial ground calcium carbonate (GCC) was also used for comparison. The effect of CaCO 3 size, shape and surface modification on the structure, mechanical and optical properties of prepared paper sheets ...
