Cationic Rosin Sizing Agent
Introduction
Cationic rosin Sizing,due to its own positive charge, can combine with negative charge of pulp fibers to achieve self-retention, also promote the retention of fillers and fine fibers, and can achieve acidic and neutral sizing within a wide range PH value. The dosage is only 3/4 of anionic dispersed rosin sizing,and aluminum sulfate anion rosin dosage is only 0-1/3 of anionic dispersed rosin sizing. Production costs can be greatly reduced, while the physical performance of paper can also be greatly improved.
Characteristics:
1. Using the technology of high-temperature and normal pressure inversion method.Fine particle size (0.6-0.8μm), distribution uniformity, stableperformance, no precipitation on shelf life and no caking.
2. The potential is equalizing,in the 24-29mv.It can achieve self-retention and near neutral sizing. No ripening period.It is ripened under the machine.
3. Good compatibility. It's easy to achieve the switch with anionic- highly-dispersed- -rosin-sizing.
4. The product is used in a wide of range. It can be applied to straw, wood pulp, recycled pulp of papermaking sizing.
5. It can completely tolerate calcium carbonate, talc and other fillers.
