Abstract

The article provides a comparative analysis of the physical and mechanical characteristics of samples of chemicalthermomechanical mass (CTMM) after the first and second stages of grinding, as well as after drying the mass. It was found that increasing the drying temperature reduces the quality indicators of wood pulp. Based on research results, methods have been proposed to reduce the phenomenon of keratinization of fibers as a result of their drying. The possibility of using chemical-thermomechanical mass in the production of cardboard is also considered. For this purpose, compositions were made from waste paper and chemical-thermomechanical mass in various percentage ratios. Research has shown that even taking into account the deterioration in the strength characteristics of the finished product when adding chemical-thermomechanical mass, the resulting properties of the composition of chemical-thermomechanical mass and waste fiber allow the production of paper for corrugation close in quality to the highest grade B-0.
