The effect of glue spreads and adhesive type on quality of laminated board from oil palm trunk

[摘要] The objective of this study was to analysis glue spreads and adhesive type on physical and mechanical properties of a laminate board from oil palm trunk and to obtain the optimum glue spread for each adhesive to manufacture laminate board. Adhesive used were polyvenil acetate(PVAc), urea formaldehyde(UF), and phenol formaldehyde(PF). Glue spread variation were 240, 260, 280 and 300g/m2. On this research, the lamina board consists of three layers. Upper and bottom layer made from the outer part of the oil palm trunks with dimension of 45cm x 5cm x 1cm, the middle layer made from the soft-inner part of oil palm trunks with dimension of 45cm x5cm x2cm and then compressed up to dimension of 45cm x 5cm x 1cm. The results will be compared with the JAS standard 243:2003. The results of this study showed that all of the physical properties fulfilled the standard of JAS 243:2003, except laminate board using PVAc adhesive. The other hand, all of the mechanical properties did not fulfil standard, except the value of MOR with treatment 240g/m2 using PF adhesive. The optimum quality in this study using PVAc, UF and PF adhesive using glue spread of 240g/m2, 280g/m2 and 240g/m2, respectively.
