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 |
