Abstract

A METHOD OF MONITORING AND OPTIONALLY CONTROLLING THE ADDITION OF ONE OR MORE SURFACE ADDITIVES TO A PAPERMAKING PROCESS IS DISCLOSED. THE METHOD COMPRISES THE FOLLOWING STEPS: (A) ADDING A KNOWN AMOUNT OF ONE OR MORE SURFACE ADDITIVES TO A PAPERMAKING PROCESS EITHER ALONE OR IN KNOWN PROPORTION WITH A KNOWN AMOUNT OF ONE OR MORE INERT FLUORESCENT TRACERS, WHEREIN THE SURFACE ADDITIVES CAN ONLY BE ADDED ALONE WHEN THE SURFACE ADDITIVES ARE CAPABLE OF FLUORESCING; (B) MEASURING THE FLUORESCENCE OF THE SURFACE ADDITIVES AND/OR ONE OR MORE INERT FLUORESCENT TRACERS AT A POINT SUBSEQUENT TO ADDING THE SURFACE ADDITIVES AND AFTER A SHEET HAS BEEN FORMED, WHEREIN THE SURFACE ADDITIVES CAN ONLY BE MEASURED WHEN THEY ARE CAPABLE OF FLUORESCING AND WHEREIN FLUORESCENCE IS MEASURED WITH A REFLECTANCE BASED FLUOROMETER (10); (C) CORRELATING THE AMOUNT OF FLUORESCENCE OF THE SURFACE ADDITIVES WHEN THEY ARE CAPABLE OF FLUORESCING AND/OR INERT FLUORESCENT TRACERS ON A SHEET WITH THE CONCENTRATION OF THE SURFACE ADDITIVES IN A COATING ON A SHEET AND/OR THICKNESS OF A COATING ON A SHEET; AND (D) OPTIONALLY CONTROLLING THE ADDITION OF ONE OR MORE SURFACE ADDITIVES TO A PAPERMAKING PROCESS BY ADJUSTING THE AMOUNT OF THE SURFACE ADDITIVES ADDED TO THE PAPERMAKING PROCESS IN RESPONSE TO THE COATING THICKNESS ON A SHEET AND/OR CONCENTRATION OF THE SURFACE ADDITIVES IN A COATING ON A SHEET.
