- La variabilidad dimensional y defectos de secado afectan rendimientos en procesos de cepillado de madera de Eucalyptus saligna Napoleón López María Fernanda Yucta Karina Caraguay Rumiñahui Minga Agrociencias harvesting eucalyptus performance workability The losses due to the large number of defects of introduced wood Eucalyptus saligna during air drying were investigated in order to improve utilization yield and quality of wood planing processes. The objective was to evaluate dimensions and defects in 300 commercial pieces: boards (240 x 12 x 3 cm) and 300 tables (300 x 20 x 2 cm), which were subjected to a process of drying on the open air for more than a year. The volume of clean wood slats was obtained for average and 8,139 cm3 were reduced to 2,243 cm3, after a theoretical defect removal, ie hypothetically discounted the geometric volume of each defect. This represented a 27.5 % yield of clean wood and a loss of 73.4 % by defect removal. In tables, the average volume was 13.240 cm3 and the clean volume was calculated 4,406 cm3, an amount that represented 33.2 % least additively to calculate correction. Given this, the removal defect by brushing and squareness was processed in a sample of 15 pieces; this reached yields of 58.4 % for tablets and 51.8 % for tables, which meant losses of 41.6 and 48.2 % respectively; these losses in the brushing process were investigated showing that they affect the performance of E. saligna. 2016 artículo científico 0304-8799 https://www.redalyc.org/articulo.oa?id=173145672016 es http://www.redalyc.org/revista.oa?id=1731 Bosque application/pdf Universidad Austral de Chile Bosque (Chile) Num.1 Vol.37
