The influence of treatment and shelling ratio on the mechanical properties of particleboard manufactured from Canola (Brassica napus) stalk particles

In this study, the effect of particle size used in surface layers and shelling ratio on the mechanical properties of there-layered particleboard manufactured from treated canola (Brassica napus) particle was investigated. The shelling ratio at three levels (2.82:16mm, 5.33:16mm and 8.6:16mm), particle size used on surface layers at two levels (>1.25 and 1.25 mm in surface layers of panels caused an increase in MOR, MOE, IB. Besides, it was determined that increment in particle size on surface layers and using water – leached treatment improved the mechanical properties of panels. According to the results, with the usage of canola stalks particles treated with hot-water used in core layer, applying particles with the dimension of >1.25mm on surface layers of three-layered panels with shelling ratio of 2.82:16mm and 5.33:16mm, it can be obtained the desirable MOR and MOE.
