Effects Of Some Manufacturing Factors On The Properties Of Particleboard Manufactured From Alder (Alnus Glutinosa Subsp. Barbata), Gökay Nemli̇
Turkish Journal of Agriculture and Forestry
In this study, Alder (Alnus glutinosa subsp.Barbata) wood was used for particleboard manufacturing. The purpose of this study was to determine the effects of particle moisture content, shelling ratio and the addition of wood dust on the mechanical properties (static bending, modulus of elasticity and internal bond) and physical property (thickness swelling) of particleboard. The addition of 10% wood dust to particles decreased the thickness swelling, modulus of elasticity and bending strength, while increasing the internal bond. Particleboards manufactured from particles with 1% moisture content had lower internal bond, modulus of elasticity and bending strength and higher thickness swelling values …

The ultimate aim of this work was to develop a phenolic resin for partially replacing phenol with modified organosolv lignin in phenol-formaldehyde (PF) resin production. The lignin-formaldehyde relationship was determined in a reactivity test. Organosolv lignin-phenol-formaldehyde (LPF) resins were produced in a two-step preparation with different additions of lignin. The method selected for the manufacture of lignin resins dealt with modification of the lignin by the methylolation route. The effects of different substitution levels of organosolv lignin on strength properties were evaluated by testing lignin resin impregnated paper strips. A comparison of the tensile properties of organosolv lignin formulations, impregnated …
