Effects of Pressing Time on Some Technological Properties of Laminated Veneer Lumber (LVL) Produced Using Nylon Waste as Adhesive
Abstract
It is desired the wood composite materials which have broaden using areas in human residence have no negative effects on human health and environment. But because of formaldehyde content of most of resins used in wood based composite production, wood composite materials have been seen a threat on human health and environment. Therefore, numerous studies have been made to develop an effective method to decrease formaldehyde emission from the wood based panels and various methods have been tried. The aim of the study was to investigate those effects of pressing time on some technological properties of nylon composite LVL. Poplar (Populus deltoides) veneers were used to produce nylon composite LVL. Three different pressing time (8, 10, 12 minutes) and pressing temperature 140 °C were chosen as press parameters in the manufacturing of nylon composite LVL. Bonding strength, bending strength, modulus of elasticity, density and equilibrium moisture content of nylon composite LVL panels were determined according to TS EN 314-1, TS EN 310, TS EN 323 and TS EN 322, respectively. The experimental results showed that technological properties of panels generally increased with decreasing pressing time.
