Pilot-Scale Wet Web Surface Treatment of Newsprint, 2000 Metered Size Press Forum

PressWeb.jpg

This report summarizes the results from trials on Paprican's pilot paper machine in which we surface-treated wet newsprint, at 46% solids content, with an experimental film applicator installed in the press section. We applied four commercial-grade starches and three polymer additives commonly used in surface treatment to the wet web at a speed of 600 m/min. A starch application of 2 g/m2 resulted in improvements in strenght and ink holdout were alos observed and almost doubled the z-direction tensile strength. Improvements in strength and ink holdout were also observed with a 0.15 g/m2 application of carboxymethylcellulose, and linting propensity decreased for two of the additives tested. Surface application of 4.3 or 6.5 g/m2 of pigment-starch mixtures resulted in impovements in strength properties, and a 3-point increase in brightness.
