Method of producing paper or cardboard |
| abstract |
A process of making paper or paper board comprising forming a cellulosic suspension, flocculating the suspension, mechanically shearing the suspension and optionally reflocculating the suspension, draining the suspension on a screen to form a sheet and then drying the sheet, wherein the suspension is flocculated or reflocculated by introducing a water-soluble polymer of intrinsic viscosity above 3dl/g into the suspension, characterised in that the water soluble polymer exhibits a rheological oscillation value of tan delta at 0.005Hz of above 1.1. The process has the advantage of improving retention. |
