Application of liquefied adhesive made of oil-palm stem for particleboard binder

Abstract

In order to evaluate the quality of liquefied adhesive made of oil-palm stem, this research compared results of physical and mechanical testing of particleboard bonded by liquefied adhesive made of oil-palm stem (LA), urea-formaldehyde (UF) and isocyanate (IC), respectively. LA was produced in laboratory and for decreasing its viscosity; it was mixed with thinner prior to spraying. UF and IC were commercially type, represented interior and exterior application, respectively. Both applications were following the standard procedure. Results of this study showed quality of the physical and mechanical properties of the particleboard bonded by LA were in between particleboard bonded by UF and particleboard bonded by IC, for instance value of MOE (kgf/cm2) was 10594 (UF) < 23529 (LA) < 24413 (IC) and MOR (kgf/cm2) was 5.37 (UF) < 18.14 (LA) < 25.35 (IC). These results indicated that LA was a promising adhesive even though in this case it can be used for interior application only.

Characteristics of Liquefied Adhesive Made of Oil-Palm Trunk (OPT) and their Application for Particleboard’s Binding

“…The polymeric structural component of OPT will be broken down in the early stages of our technique, and then the liquefaction solvent will react with these broken-up pieces to generate a derivative, which will then all dissolve in the free solvent in the latter stages, resulting in lower viscosity. The final viscosity of the liquefied glue was 96.22 cP, which was similar to our prior study [44] and close to the standard range of 130-300 cP. This viscosity enabled spraying application for producing fiberboard or particleboard.…”

Panel products made of oil palm trunk bagasse (OPTB) and MMA (Methyl methacrylate)-styrofoam binder

“…The MC of the OPTBparticleboard produced has met JIS A 5908-2003 standard (5-13%). The condition of MC of the OPTBparticleboard bonded with MMA-Styrofoam was like the previous work [6] which applied liquified adhesive, urea-formaldehyde resin, or isocyanate on wood-particleboard. In addition, the comparison OPTBparticleboard bonded PF adhesive has an MC value that fluctuates between 8.1-11.1%, relatively higher than the OPTB-particleboard bonded with MMA-Styrofoam.…”

“…Oil palm trunks can be used as wood products such as plywood [5], particleboard [6], composite-plywood [7], laminated board [8], and hybrid plywood biocomposites [9], and fiberboard [10]. Moreover, oil palm trunks can be used for bioplastic materials [4,11,12].…”
