Potential use of Pinus patula wood for frames and edge glued panels

Abstract

Wood and engineered wood products can be used to replace non-renewable materials in construction and furniture, contributing to a more sustainable society. This study aimed to assess the potential of Pinus patula wood for the production of frames and edge glued panels, and to maximize production process variables, adhesive weight, and pressure, in order to generate a product with adequate quality at the lowest cost. environmental. Fingerjointing and edge gluing were performed. The finger joint gluing was carried out industrially using PVA adhesive. Edge gluing was carried out on a laboratory scale under 18 experimental conditions: 16 with Pinus patula and 2 with Pinus taeda (control). The variables studied were the glue type (PVA and EPI), grammage (160, 180, 200, and 220 g.m^-2), and pressure (7 and 10 kgf.cm^-2). The finger joint gluing quality was assessed by flexural and tensile tests (ASTM, 2019) and edge bonding by shear strength (ES, 2009). The results showed that Pinus patula has potential for the production of frames and edge glued panels, and that process variables can be maximized when using EPI adhesive.
