Effect of Resin Type, Pressing Temperature and Time on Particleboard Properties made from Sorghum Bagasse

Abstract

Sorghum bicolor L Monech part Numbu as potential materials for particleboard manufacturing due to its cellulose, hemicellulose and lignin content similar with wood. The objective of the research was to determine the adhesive type, pressing temperature and time on physical and mechanical properties of particleboard made from sorghum bagasse. Size of board was (300 x 300 x 10) mm 3 , 0.7 g cm -3 targeted density, 10% resin content of urea formaldehyde (UF), and Phenol Formaldehyde (PF), 7% for Isocyanate, over all based on oven-dry particles. Furnish (mixture of particle and resin) was placed in hot press machine at temperature of 120 °C and 130 °C for UF, 170 °C and 180 °C for PF, 150 °C and 160 ° C for Isocyanate. Time of pressing in this experiment was 8 and 10 minutes. The result showed that Isocyanate resin was the best resin for resulting of physical and mechanical properties. Almost all those parameters had fulfill to the requirement of JIS A5908-2003.
