ANIONIC TRASH CONTROL IN PAPERMAKING: MECHANISM AND APPROACH
Anionic trashes (AT) are released into the water phase from contaminated reused water, recycled fibre, or broke, and form deposits at papermaking process including the wet-end, press section, machine fabrics and rolls. The AT can cause lowering of productivity by defective products, sheet breaks, short shutdown duration. The lab and field trials showed that troubles from AT can be controlled by dosing cationic fixing agent. This paper examines: the mechanism of troubles from AT, selection of the most compatible additive, and monitoring machine performance.
