Objective
TACKY IMPURITIES (STICKIES), WHICH IN PAPER MILLS USING WASTE PAPER RESULT IN A DISTURBANCE IN PRODUCTION AND A DECREASE IN OUTPUT,MAY BE FORMED BY THE SYNERGISTIC COREACTIOW OF ADDITIVES CONTAINED IN THE WASTE PAPER (COATINGS, SURFACE AGENTS, ADHESIVES ETC.) AND THE PROCESS MATERIALS REQUIRED IN THE PRODUCTION OF PAPER. THE PHENOMENA WHICH OCCUR ARE VERY COMPLEX AND MUST BE INVESTIGATED SO THAT THE NATURE AND INTENSITY OF THE INFLUENCE OF CERTAIN COMPONENTS CAN BE STATED AND RECOMMENDATIONS CAN BE GIVEN REGARDING THEIR USE OR THEIR MODIFICATION.
THE BASIS FOR THAT WORK WILL BE FURNISHED BY A COMPLETE ANALYSIS OF SAMPLES OF TACKY IMPURITIES TAKEN IN PAPER MILLS IN WHICH WASTE PAPER IS USED. THE ANALYSES WILL BE CONDUCTED IN ACCORDANCE WITH THE PROGRAM WHICH HAS BEEN DEVELOPED IN OUR RESEARCH LABORATORY AND HAS PROVED SATISFACTORY IN A PREVIOUSLY CONDUCTED AND COMPLETED INVESTIGATION REGARDING TACKY IMPURITIES. THIS ANALYTICAL WORK WILL HAVE THE FOLLOWING AIM:
- TO DISCOVER THE SOURCES OF THE WATER-SOLUBLE AND WATER-INSOLUBLE ORGANIC COMPOUNDS AND OF THE INORGANIC COMPONENTS. IN PARTICULAR THE WATER-SOLUBLE COMPOUNDS, WHICH ARE MOSTLY CONTAINED IN THE FIBROUS MATERIAL, HAVE NOT YET BEEN SUFFICIENTLY INVESTIGATED ALTHOUGH THEIR PROPORTION IN TACKY IMPURITIES MAY BE RELATIVELY HIGH.
- THE INVESTIGATION OF THE RELATIONSHIP BETWEEN THE MOLECULAR WEIGHT AND THE MOLECULAR WEIGHT DISTRIBUTION OF THE ORGANIC CONSTITUENTS OF TACKY IMPURITIES AND THE FORMATION OF TACKY IMPURITIES. THIS PART OF THE INVESTIGATION IS PARTICULARLY SIGNIFICANT BECAUSE THE PARAMETERS TO BE MEASURED (MOLECULAR WEIGHTS) DETERMINE NOT ONLY THE TACKINESS OF THE CONSTITUENTS BUT ALSO THEIR TENDENCY TO BE ADSORBED BY, E.G. INORGANIC PARTICLES. THE TENDENCY TO BE PRECIPITATED OR TO AGGLOMERATE IS ALSO INFLUENCED BY THESE PARAMETERS.
REGARDING THE PROCESS MATERIALS USED IN MAKING PAPER, THE INVESTIGATION OF PURE SUBSTANCES WHICH CAN BE OBTAINED FROM THE PRODUCERS OF PROCESS MATERIALS MUST BE SUPPLEMENTED BY ANALYSES OF AQUEOUS LIQUORS WHICH HAVE DRAINED THROUGH THE WIRE AND OF AQUEOUS LIQUORS WHICH HAVE BEEN CIRCULATED AND WHICH MAY CONTAIN SUCH SUBSTANCES SOMETIMES IN HIGH CONCENTRATIONS. A REGULAR COLLECTION OF SAMPLES IN PAPER MILLS WILL ASSIST THE DISCOVERY OF CORRELATIONS BETWEEN THE NATURE AND QUANTITIES OF THE PROCESS MATERIALS USED AND THE OCCURRENCE OF TACKY IMPURITIES. AN OBSERVATION OF THESE RELATIONSHIPS THROUGH SEVERAL YEARS WILL FURNISH A BASIS FOR THE INTENDED PREPARATION OF RECOMMENDATIONS FOR THE USE OF PROCESS MATERIALS.
