“…Monitoring the dust level in the workplace may also be necessary. A well-fitted, effective respirator should also be used if other dust control measures are not practical [65][66][67][68][69][70][71][72]. It is also highly recommended to minimize the exposure time of personnel within the woodworking machine surroundings that create the dangerous dust.…”

During production, thermally modified wood is processed using the same machining operations as unmodified wood. Machining wood is always accompanied with the creation of dust particles. The smaller they become, the more hazardous they are. Employees are exposed to a greater health hazard when machining thermally modified wood because a considerable amount of fine dust is produced under the same processing conditions than in the case of unmodified wood. The International Agency for Research on Cancer (IARC) states that wood dust causes cancer of the nasal cavity and paranasal sinuses and of the nasopharynx. Wood dust is also associated with toxic effects, irritation of the eyes, nose and throat, dermatitis, and respiratory system effects which include decreased lung capacity, chronic obstructive pulmonary disease, asthma and allergic reactions. In our research, granular composition of particles resulting from the process of longitudinal milling of heat-treated oak and spruce wood under variable conditions (i.e., the temperature of modification of 160, 180, 200 and 220 °C and feed rate of 6, 10 and 15 m.min−1) are presented in the paper. Sieve analysis was used to determine the granular composition of particles. An increase in fine particle fraction when the temperature of modification rises was confirmed by the research. This can be due to the lower strength of thermally modified wood. Moreover, a different effect of the temperature modification on granularity due to the tree species was observed. In the case of oak wood, changes occurred at a temperature of 160 °C and in the case of spruce wood, changes occurred at the temperatures of 200 and 220 °C. At the temperatures of modification of 200 and 220 °C, the dust fraction (i.e., that occurred in the mesh sieves, particles with the size ≤ 0.08 mm) ranged from 2.99% (oak wood, feed rate of 10 m.min−1) to 8.07% (spruce wood, feed rate of 6 m.min−1). Such particles might have a harmful effect on employee health in wood-processing facilities.

“…The purposes of these applications are to increase physical, mechanical, and surface properties, to suppress the absorption of water and humidity, and to eliminate the release of formaldehyde emission (Nemli and Colakoglu, 2005;Nemli and Hiziroglu, 2009;Ozdemir et al, 2009;Nemli et al, , 2007. Surface improvement by the lamination depends on the materials used in laminating and the system used for lamination (Ahonen, 1977;Ozdemir et al 2009).…”

“…The surface roughness of the wood surface could be affected by sanding treatment. The roughness parameter (Ra) was used to examine the surface roughness of poplar wood samples (Nemli et al 2007;Sulaiman et al 2009;Nadir Ayrilmis 2010). The contact angle of water and measured roughness parameter are shown in Table 1 and Fig.…”

Wettability of Sanded and Aged Fast-growing Poplar Wood Surfaces: I. Surface Free Energy

et al. 2014

View full text Add to dashboard Cite

The sanding process influences the surface morphology and chemical components of wood, which are two important factors that influence the surface free energy and wettability of wood. The objective of this study was to investigate the roughness of sanded poplar wood and the effects of sanding and aging on the surface free energy using different methods. The roughness parameter (Ra) decreased as the grit number increased, but no change was evident when the grit number increased from 120 to 240. The contact angle of water on the fresh wood samples decreased as the grit number increased. Fresh wood samples were more easily wetted by water than was the aged wood sample, and the contact angles increased as the surface roughness decreased. The surface free energy of sanded, aged wood obtained by the Zisman method may be unsuitable. For the fresh wood samples, the change of surface free energy and its components were not significantly changed when the grit number was higher than 120; for the aged wood samples, the dispersion component appeared to increase slightly as the grit number decreased. The effect of roughness on the acid/base component, acid component, and base component calculated by the vOCG method was unremarkable. The surface free energy of the wood samples (obtained using the liquid parameters provided by Volpe and Siboni (1997)) can effectively balance the relationship between the acid and base components.
