| Abstract:The characteristics of synthetic calcium silicate filler and its application in low density printing paper were studied. The results showed that synthetic calcium silicate had honeycomb porous structure, with large specific surface area, low density, low abrasion value, and other characteristics. It contained a certain amount of chemical structural water with strong hydroxyl holding capacity. Compared with precipitated calcium carbonate (PCC), synthetic calcium silicate retention and drainability of the furnish were better than PCC where it was used as the filler in low density printing paper production, and it could endow the paper with higher bulk, and smaller negative effluence on tensile strength and sizing degree, it could also increase the amount of filler addition effectively. |
