Particleboard Products from Bamboo Wastes of Chopstick Factorty

Abstract

This study focused on utilizing scraps from bamboo chopsticks to manufacture particleboard. The objectives were to study the method to produce particleboard from bamboo chopsticks, to test the mechanical properties of the bamboo board in accordance to Thai Industrial Standard (TIS 876-2004), to utilize a suitable type of adhesive for bamboo chopsticks, raw material for particleboard manufacturing, and to study the optimum resin dosing. A comparison between the mechanical properties was also done between a dosage of Polymeric Diphenylmethane Diisocyanate (pMDI) resin at 3, 5 and 7% compared to urea formaldehyde resin at 8, 10 and 12%. The statistical differences were analyzed using ANOVA and Duncan’s New Multiple Range Test. The study revealed that bamboo particleboard utilizing both pMDI at 7% and urea formaldehyde at 12% passed the Thai Industrial Standard (TIS 876-2004). The study found that the amount of adhesive suitable for the production of bamboo particleboard is pMDI at 7% dosing rate, which resulted in the highest values of physical properties including average density (at 659.53 kg/m3), moisture content (at 9.62%) and thickness swelling (at 3.55%). The dosing rate at 7% pMDI also resulted in the highest values of mechanical properties which included modulus of rupture (at 15.98 MPa), modulus of elasticity (at 2,661.97 MPa) and internal bond (at 1.12MPa).
