Abstract

Optimization of process conditions in oriented strand board (OSB) manufacturing is a very important issue for both reducing cost and improving the quality of panels. Taguchi experimental design technique was applied to determination and optimization of the most influential controlling parameters of OSB panels such as press condition (pressure-time-temperature) and the ratio of adhesive parameters on modulus of elasticity (MOE). The value of the MOE is one of the very important mechanical properties of OSB panels. For this purpose, several experiments were conducted according to Taguchi L27 orthogonal design. The signal-to-noise (S/N) and the analysis of variance (ANOVA) were used to find the optimum levels and to indicate the impact of the controlling parameters on MOE. A verification test was also performed to prove the effectiveness of Taguchi technique. Since the predicted and the measured values were very close to each other, it was concluded that the Taguchi method was very successful in the optimization of effective parameters in OSB’s manufacturing.

Summary

Introduction

Oriented strand boards (OSB) are a relatively new kind of wood-based panels that are defined in the European Standard. OSB is a multilayer structural panel made from wood strands by drying, sizing, oriented formation and hot pressing, in which the strands comprise uniformly thick and long wood shavings (Sumardi et al, 2007). While the strands in the surface layers are aligned in parallel to the board length or width, the strands in the core layers can be randomly oriented or perpendicular to the surface layers for enhancing product strength and stiffness (Semple et al, 2015). OSBs, wood-based panel products are classified into four types ranging from general purpose boards to high load-bearing boards in the humid conditions according to the European Standard (EN 300: 2006).
