Study on Preparation and Properties of Agro-waste Particleboard at Various Press Temperatures

saw win, Win Win Nu, Thet Thet Hla Aung

Abstract


This study concerns the influence of temperature on changes in physical and mechanical properties of particleboard fabricated from betel nut (Areca catechu L) fiber (Agro-waste) and urea-formaldehyde adhesive during hot-pressing with multiple press temperatures (120, 130, 140, 150 and 160°C) at 15 minutes. The physical and mechanical properties of particleboards were determined by British Standard (BS-1811) and Indian Standard (IS-3087) Methods. For some physical and mechanical properties, it appears that moderately degrade occurs until mat temperature 130°C. Control of hot-press temperature appears a potential method to heat-treat particleboard and enhance its serviceability. The particleboard made at press temperature 150°C had the best product quality of thickness (0.50 cm), water absorption (4.5%), thickness swelling (11.11%), hardness (88.0 Shore D) and modulus of rupture (99.22 kgcm-2). These results obtained fulfilled to FAO, SNI (2013) standards. The control of pressing temperature is the one of main important factors for particleboards preparation
