Title: Development of unbonded and bonded areas in relation to Populus species wood characteristics in grinding

Description: In terms of fibre development in mechanical pulping, most of the energy is spent on the creation of specific surface area. The total surface area created can be divided into two categories: surface area that adds to the unbonded area (optical properties) and surface area that adds to the bonded area (strength properties) of mechanical papers. This paper considers these two types of physical characteristics developed during grinding of Populus species wood. Wood fibre characteristics are used to explain the variation of the development of bonded and unbonded areas. It is shown that the development of unbonded and bonded areas when grinding Populus species is a function of wood cell wall thickness, and thin-walled wood sources produce significantly higher unbonded and bonded areas at constant specific energy consumption. It is also shown that a constant specific energy consumption control philosophy does not compensate for changes in the wood characteristics.

Keywords: Mechanical pulping process, poplar, paper, mechanical properties, optical properties, plant cell walls, surfaces, regression analysis, energy consumption, wood fibers, pulp and paper processes, Populus, tensile strength, grinding of pulp
