| Abstract:A fly ash based calcium silicate(FACS), with a highly porous surface structure, high specific surface area (121 m2/g), and low bulk density (0.31 g/cm3) was used as filler in papermaking. In this paper, the application of CPAM-bentonite micro-particle retention and drainage system along with FACS was studied and its effect on drainage, retention and paper properties was investigated. The results from dynamic retention and drainage tests showed that, the pulp containing FACS as filler consumed more CPAM than using GCC as filler. When bentonite dosage was 0.1%, with increasing of the amount of CPAM, FACS-filled pulp had better retention and worse drainage. When CPAM dosage was 0.08%, with increasing of bentonite less than 0.2%, drainage and retention behavior of FACS-filled pulp was obviously improved. The filled paper properties indicated that FACS filled paper had similar brightness, higher opacity, 11.2% lower tensile index, 21.0% lower tear index, 41.7% higher bulk than those loaded with GCC. SEM observation of the paper sheets loaded with FACS figured that the fibers were well intertwined with FACS. |
