Adhesive as a Factor Affecting the Properties of Laminated Wood

Abstract

This study focuses on changing wood's bending properties using several types of adhesives. The strength, flexibility, and durability (service life) of laminated wood, glued with four types of adhesives, were examined. The results were compared with solid beech wood, conditioned to 9% moisture content. Depending on the adhesive used, the results indicate that laminated (layered) wood improved the strength and bending characteristics in comparison to the intact wood. Gained knowledge about materials properties have practical applications in the area of dynamic stress (e.g., as components of vibrating machinery mechanisms or in constructing beds, chairs, and sports equipment).

Effect of the surface finishing methods on particleboard volatile organic compounds and formaldehyde emission

“…The surface of the specimen was sanded with 100-mesh sandpaper to remove the paraffin layer of the base material surface. The 50 g of UF adhesive, 12.5 g of PVAc adhesive, 7.5 g of flour, 15 g of water, and 0.5 g of ammonium chloride with 20% concentration was mixed to prepare the UF/PVAc hybrid adhesive (Gáborík et al 2016). The weight of the adhesive on each side of particleboard was 8.28 g. After applying the veneer on the base material for 30 min, the specimens were fed into the hot-pressing machine (BY60222/2; Zhengtai Machinery Manufacturing Co., Ltd., Linyi, China) at conditions of 120 °C, 1 MPa pressure, and 3 min pressing time (Hu et al 2005).…”

Enhancing Mechanical Properties of Rhizophora Apiculata Through Engineered Laminated Boards

“…(Percin et al, 2015). Excellent mechanical properties enable them to be utilized in a broad range of products especially after undergoing modification in the production of layered (laminated) wood with better strength or bending properties (Gáborík et al, 2016). Wood laminating materials are obtained by bonding two or more layers with adhesive and joining the fibre directions of the layers parallel or perpendicular to each other (Cibo et al, 2018).…”

Laminating is a technique that improves the value of the wood material while enabling changes in the wood's properties and can be altered via in various ways which comprise multiple layers of wood, most frequently in the form of veneers (thin slices), glued and pressed together (Gáborík et al, 2016). The established laminated products which are oriented strand board (OSB), laminated veneer board (LVL), Strand-based composites include parallel strand board (PSL), laminated strand board (LSL) and oriented strand board (OSL), and also Glue-laminated timber (GLULAM) (Shmulsky and Jones 2019;Wiegner et al, 2009;Ong 2015).…”
