High-efficiency strength program used for making paper in higher charge demand system |
| abstract |
A method of enhancing paper strength properties is provided. The method comprises treating a paper sheet precursor with a polyaluminum salt, and a strengthening agent, wherein the strengthening agent comprises a dialdehyde-modified polyacrylamide copolymer and a polyacrylamide copolymer. The polyaluminum salt may be polyaluminum chloride. The methods have been demonstrated to provide, among other things, improvements in retention, strength, and dewatering. |
