Mineral Based Boards made from Lignocellulosic Wastes: 1st Part - Physical And Mechanical Properties

Abstract

Lignocellulosic waste of eggplant and tomato stalks has used with minerals of olivine and dolomit at various proportions to produce experimental particleboards that have subject to some physical and mechanical tests. In this regards, Thickness Swelling in water (TS, %), Water Absorption (WA, %), Internal Bond (IB), Bending Strength (MOR), Modulus of Elasticity (MOE) and color properties (CIE,L,a,b) of the boards were examined. It has observed that type and content of minerals effects TS and WA of test panels. Besides the internal bond strength values of the test boards that were generally higher than 0.28 N/mm2, it was found that the bending resistance properties of the boards produced with tomato stalk/dolomite mixture show higher MOR values in similar manufacturing conditions than those produced with olivine. However, boards prepeared from tomato/eggplant stalks proportions with dolomite/olivine mixture sho lower MOE values than the standard value in all production conditions.
