| Abstract:A large amount of broke is recycled during the coated art paper production, and the broke recycling would affect the wet end environment and the properties of final products. The effects of the art coated broke recycling on the first pass retention, filler retention and drainage properties of the slurry were studied while CPAM-bentonite retention system was applied, and the factors affecting the slurry retention were investigated with orthogonal experimental design. The results showed that art coated broke recycling negatively affected the retention and drainage of the slurry. With the increase of the recycled broke pulp, the first pass retention, filler retention and drainability of the slurry decreased. The addition of CPAM and PAC could improve the retention and drainage of the slurry. The primary factor affecting slurry retention was CPAM dosage, and then the amount of broke pulp and PAC dosage. The increase of CPAM and PAC dosage could improve the slurry retention as the recycled art coated broke pulp increased. |
