Adsorption of polysaccharide wet-end additives in papermaking systems
The adsorption of polysaccharide guar gum and starch additives and their interactions with cellulosic fiber and fines, as well as soluble and colloidal carbohydrates, present in wood pulp suspensions were investigated by employing HPLC and spectrophotometry. A unique phenomenon, i.e. carbohydrate uptake or ‘substraction’, was observed to occur in a variety of cellulosic systems [whole pulp, was...

متن کاملFour-dimensional Characterization of Paper Web at the Wet End
This report presents a detailed description of a vision system whose purpose is to detect and to localize the nonuniformities that appear on the paper slurry (wood fiber and water mixture) at the wet end of a paper machine. Specifically, the system is capable of monitoring the paper slurry upon its exit from the headbox and alerting the operators of any event (e.g., streaks) that disrupts the o...
