Method for Determining a Sizing Agent Concentration, Particle Size and a Sizing Agent Particle Size Distribution in a Peper Pulp

摘要

Method for determining the size concentration, the particle size and the particle size distribution of natural and/or synthetic sizes in a paper stock by staining a sample of the particles (T_i) of the size with a fluorescent dye, light being radiated into the sample of fluorescent or fluorescently stained particles and scattered light and/or fluorescent light from the sample being recorded and evaluated, and use of this method for determining the particle size distribution of reactive size particles in the paper stock or in the white water of paper machines during papermaking.
