Physico-mechanical comparison of urea formaldehyde bonded particle board manufactured from jute sticks and wood of Trewia nudiflora

Abstract

This study is to know the physical and mechanical properties of particle board made up of jute sticks (jutex board) and wood chips (woodex board) of Trewia nudiflora. Two leading particle board manufacturing industries of Bangladesh were selected first which have the same manufacturing process and adhesive composition. Boards of available thicknesses were collected randomly. From each thickness category, three replications were taken. The parameters were studied as adhesive composition,mass of a board, density, bending strength, modulus of elasticity,surface soundness, tensile strength, screw withdrawal, pressure and pressing time. Urea formaldehyde resin is used to manufacture both types of particle board. For achieving the greater efficiency of boards, some chemical compounds were mixed with the resin. Due to the change in thicknesses, boards were not always different in terms of the physical and mechanical properties. Moreover, except the modulus of elasticity (MOE), woodex boards were superior to the properties of jutex boards.
