Statistical Process Control of Starch Viscosity

TAPPI TIP 0304-15 – Statistical Process Control of Starch Viscosity

Control of the viscosity of a starch-based corrugating adhesive is critical to controlling the operation of the corrugating process and to obtaining good corrugator runnability. Viscosity that is too high will be difficult to pump, will not flow properly in the pan and will not adequately penetrate the linerboard and medium surfaces. Viscosity that is too low will not be picked up properly by the applicator rolls and will penetrate the linerboard and medium surfaces too quickly. To obtain a true picture of the state of control over the starch preparation and corrugating process, statistical process control techniques should be employed.
