| Abstract:Different precipitated calcium carbonates (PPCs) with various morphological characteristics were prepared and their properties and performances as filler used in paper were studied. The results showed that needle-like PCC had higher oil adsorption value and sediment volume, paper filled with needle-like PCC had higher opacity and higher whiteness compared with that filled with commercial PCC, the strength of paper was also improved. Amorphous PCC had lower oil adsorption value and higher sediment volume. The paper filled with amorphous PCC showed lower strength, opacity, whiteness. The spindle-like calcium carbonate had the same filling effect with commercial PCC. The papers filled with different kinds of calcium carbonate had the similar sizing degree. |
