SIFAT FISIK-MEKANIK PAPAN PARTIKEL DARI LIMBAH FINIR BERDASARKAN JUMLAH LAPISAN DAN KERAPATAN

Abstract

This research was aimed to examine the physical and mechanical properties of particleboard from veneer waste based on number the layers and density, and to obtain the number of layers and density to fullfill the JIS A 5908 : 2008 type 8 standard. This research were conducted at Wood Workshop Laboratory, Wood Processing Laboratory Faculty of Forestry, and PT. Duta Pertiwi Nusantara Laboratory. The materials used were veneer waste, urea formaldehida adhesive type 02 C, liquid, and paraffin. The method used in this research were a factorial experiment in random design complete (RAL) with two factors is factor A (number of layers) consist of single layer particleboard and three layers particleboard, and factor B (density) consist 0,6 g/cm³, 0,7 g/cm³, and 0,8 g/cm³. Particleboard size were 30 cm x 30 cm x 1 cm and pressed at 165⁰C for 6 minutes with pressure 30 kg/cm². The results of the research showed that density, moisture content, thickness swelling (single layer and three layers  particleboard 0,6 g/cm³ density), MOE (single layer particleboard 0,8 g/cm³ density), MOR, internal bonding, and screw holding strength  fulfill JIS A 5908 : 2003 type 8 standard.  The best particleboard is single layer particleboard with density 0,8 g/cm³.
